    [0003] TECHNICAL FIELD OF THE INVENTION
    [0004] The present invention is related to a two-wire electronic control home automation device, that is, it comprises only two terminals intended to be connected to an electrical panel and to an active load, such as a lighting lamp. The lamp assembly and home automation device are connected in series.
    [0005] The present invention is related to two-wire home automation devices that comprise an electronic switch.
    [0006] a home automation unit comprising at least one microcontroller for controlling the electronic switch and an electronic home automation component that consumes a lot of energy at least in an on state. The electronic switch can have a variator mode, which allows controlling the power absorbed by the lamp to vary its luminosity according to the user's need or a switch mode, which allows the load to be supplied without controlling its absorbing power for operation as a mechanical switch, that is, all or nothing according to the user's need.
    [0007] STATE OF THE ART
    [0008] A two-wire electronic control home automation device A is known comprising a leakage current supply unit 1, an electronic switch 2 and a home automation unit 3.
    [0009] [Fig. 1A] represents a functional block diagram of a home automation device A of this type connected to a lamp L and to a power supply S. The leakage current supply unit 1 is mounted parallel to electronic switch 2.
    [0010] Figure 1A schematically represents the home automation device in an off mode, that is, when a lamp L is off and therefore the electronic switch 2 is in a locked state, also called an open state. In this off mode, the leakage current supply unit 1 supplies current, referred to as the leakage current Ia off, to the home automation unit 3 to supply it. Arrows in bold represent the circuit of the leakage current Ia turned off in figure 1A. Therefore, the leakage current Ia off passes through the home automation device A and through the lamp L. This leakage current Ia off is insufficient for the lamp L to produce a light visible to the user.
    [0011] [Fig. 1C] represents the home automation device in an on mode, that is, when the lamp is powered by a power supply I on. The electronic switch 2 in the saturated state short-circuits the leakage current supply unit 1.
    [0012] The leakage current supply unit 1 comprises a capacitor, not shown, which makes it possible to supply the home automation unit 3 while the electronic switch 2 is in the saturated state. However, the capacitor discharges. In the on mode, therefore, the home automation unit 3 controls the electronic switch 2 in phase angle dimmer mode to allow recharging of the capacitor by opening the electronic switch 2 so that the current passes as when the lamp is off.
    [0013] When the home automation unit receives a request for the on status at 100 % load, the control unit cannot, therefore, send the current for a whole period, since a time is required in the status blocked, even if this time in the blocked state of switch 2 is short with respect to the time in the saturated state.
    [0014] [Fig. 1B] represents a half period of the voltage at the terminals of the lamp in dimmer mode.
    [0015] The electronic switch 2 is in a locked state during a non-conduction phase 20 for a time t in every half period, so that the leakage current supply unit 1 can charge its capacitor while simultaneously supplying the home automation unit 3. During this phase of non-conduction, a leakage current Ia turned off, therefore, passes in the lamp.
    [0016] The electronic switch 2 is in a saturated state in a conduction phase 21 for the remainder of the half period time. During this conduction phase 21, the electronic switch 2 supplies the lamp L and short-circuits the leakage current supply unit 1. During the conduction phase 21, the charged capacitor supplies the home automation unit 3.
    [0017] In this way, even when the electronic switch 2 is controlled to supply a load in maximum mode, that is, a cyclical ratio in conduction phase 21 as close to 1, it is necessary to still have a part of the medium period, in non-conduction phase 20 for the leakage current supply unit to recharge the capacitor.
    [0018] However, this dimmer mode is problematic for so-called non-dimmable, that is, non-variable or non-dimmable loads, contrary to so-called dimmable or dimmable or variable loads. For example, the load can be a dimmable or non-dimmable lamp. By lamp, it is understood an incandescent or halogen or fluocompact bulb lamp or also an light-emitting diode lamp or any other types of lamps. electrical Indeed, lamps containing electronics, called electronic lamps, whether dimmable or non-dimmable, comprise a capacitor that provides a current draw during a conduction step, that is, from a non-conducting phase to the conducting phase. Indeed, during the charging of the capacitor integrated in the electronic lamp, the lamp produces a current draw that can be several amperes. This current draw can cause flickering, crackling and / or overheating in the electronic lamp, causing discomfort to the user and damage to the electronic lamp or switch.
    [0019] To decrease this current call, it is known that the conduction step is carried out as close to the zero sector, that is, at the beginning of a half period when it is at zero volts. The capacitor of the non-adjustable electronic lamp cannot be fully discharged, it maintains a voltage level at the lamp terminals, which causes the synchronization principle of the control unit 3 to become out of phase. This phase shift leads to overheating of the lamp and home automation device, as well as a crackling effect from the lamp.
    [0020] Two-wire devices are known without a home automation electronic organ that consumes a lot of energy, such as a home automation radio, which comprise, for example, diodes in series with the electronic switch so that the sum of the potential differences at the terminals of the Each diode enables a low consumption control unit to be powered, which controls the electronic switch. However, such a device is devoid of a home automation electronic organ that consumes a lot of energy, such as a home automation radio. Indeed, the supply by the series diodes does not it allows powering a radio whose consumption is significant and causes additional overheating of the switch.
    [0021] Three-wire home automation devices are also known that comprise electronic switches to control a load in all or nothing or in variator mode. However, some types of three-wire home automation devices of this type cannot replace a two-wire switch in a housing without works. Indeed, most two-wire switches have only one phase input wire and one lamp output wire to connect the phase to the lamp.
    [0022] SUMMARY OF THE INVENTION
    [0023] It is found that there is a need to provide a two-wire electronic control home automation device that allows feeding a load in full wave while feeding an electronic home automation device that consumes a lot of energy in the full wave state. The load can be, for example, a so-called dimmable or dimmable or variable lamp or a so-called non-dimmable or non-dimmable or non-dimmable lamp, eliminating its flickering and overheating.
    [0024] According to the invention, the aim is to satisfy this need by providing a two-wire home automation device with electronic control to control the power supply of a load, the device comprising:
    [0025] • a load terminal to connect to the load,
    [0026] • a sector terminal to connect to a phase of a sector, • an electronic switch connected between the load terminal and the sector terminal to control a supply current that supplies the load,
    [0027] a home automation unit comprising a microcontroller to control the electronic switch at least in an on state and a home automation electronic organ that consumes a lot of energy at least in an on state,
    [0028] a power supply unit comprising an input terminal and an output terminal, connected to the electronic switch, so that the supply current passes through the supply unit between the sector terminal and the load terminal, the supply unit comprising:
    [0029] i. a power circuit comprising:
    [0030] 1. an energy storage element connected to the input and output terminals of the power supply unit,
    [0031] 2. a transformer supply comprising a primary coil mounted in parallel to the energy storage element and a secondary coil to power the home automation unit including the microcontroller,
    [0032] ii. an electronic bypass switch connected between the output terminal and the input terminal in parallel with the power circuit, the electronic bypass switch comprising a knob connected to the power circuit to control it either in an open position that allows the power supply of the supply circuit when the storage element is in a discharged state until it is in a charged state, either in a closed position to short-circuit the supply circuit when the storage element is in the charged state until it is in the discharged state.
    [0033] By "connected", it is meant electrically connected. By "connected", we mean electrically connected, that is, by connected by means of a system of connections.
    [0034] By "phase", we mean the phase or neutral of the sector supplying the load. The home automation device of the invention allows, by means of the power supply unit comprising the transformer supply, to power the home automation unit without cutting off the power supply to the load. When the electronic bypass switch is in the open position, the transformer supply is supplied by the switch and when it is in the closed state, the transformer supply is supplied by the energy storage unit. In other words, the power circuit allows the home automation unit to be powered while simultaneously powering the load, such as a full-wave lamp.
    [0035] Indeed, in the case of a full-wave switch command, when the electronic bypass switch is closed, the voltage at the load terminals corresponds to the sector voltage minus the switch losses. In the closed position, the power circuit can continue to power the home automation unit by means of the energy of the energy storage element that electrically feeds the transformer supply. When the electronic bypass switch is in position When open, the current flowing through the load passes through the power circuit that recharges the energy storage element and feeds the transformer supply in parallel, which allows the home automation unit to be powered. In the open position, the voltage at the load terminals corresponds to the sector voltage minus the losses of the switch and the supply circuit.
    [0036] The device according to the invention can also have one or more of the characteristics below, considered individually or according to all the technically possible combinations:
    [0037] According to a first embodiment, the home automation device with electronic control is only two-wire.
    [0038] By "two-wire", it is understood that the home automation device comprises only a load terminal and a sector terminal connected to one phase of the electrical network to be connected in series with the load. In other words, the home automation device does not It comprises a third terminal that allows it to be connected to the other phase of the sector to be connected in parallel to the load.
    [0039] According to a second embodiment, the device comprises a comparator that compares a voltage as a function of the supply voltage of the energy storage element with a maximum threshold voltage and a minimum threshold voltage, the comparator comprises a control output directly connected to the control of the electronic bypass switch and comprises a closing command state in which the comparator comprises a voltage at its output to control the electronic bypass switch in the closed position and an opening command state in which the voltage at the Comparator output controls the electronic bypass switch in the open position and because the comparator goes from the open command state to the close command state when the voltage as a function of the voltage at the terminals of the energy storage element is greater than the maximum threshold voltage and because the comparator goes from the closing command state to the opening command state when the voltage as a function of the voltage at the terminals of the energy storage element is lower than the minimum threshold voltage.
    [0040] This allows the electronic bypass switch to be directly controlled based on the state of charge of the energy storage element to either supply the transformer supply by the energy storage element when the electronic bypass switch is in the closed state, either supply the transformer supply by the sector. Thus, the minimum threshold voltage is an image voltage of a supply voltage of the discharged storage element with respect to the voltage as a function of the supply voltage of the storage element and the maximum threshold voltage is an image voltage of a voltage of Power supply of the charged storage element with respect to the voltage as a function of the supply voltage of the storage element.
    [0041] According to an example of this second embodiment, the comparator comprises at least one operational amplifier.
    [0042] According to an example of this second embodiment, the comparator comprises a non-inverted Schmitt trigger assembly.
    [0043] For example, the power circuit comprises a resistor across the Schmitt trigger op amp output connected to an electronic bypass switch knob to control the electronic switch.
    [0044] For example, the supply circuit comprises a reference supply comprising at least one capacitor for supplying a reference voltage at the negative terminal of the Schmitt trigger operational amplifier.
    [0045] For example, the reference supply is a capacitor mounted in parallel with a resistor connected between the positive and negative terminals of the op amp.
    [0046] According to one example, the supply circuit comprises a comparator supply for supplying a voltage to the comparator.
    [0047] According to one example, the supply circuit comprises a storage element supply voltage level sensor for supplying the voltage as a function of the voltage at the terminals of the storage element.
    [0048] According to a variant of the previous example, the voltage as a function of the voltage at the terminals of the storage element is directly the voltage at the terminals of the storage element.
    [0049] According to one example, the power supply circuit comprises a threshold voltage supplier that makes it possible to supply the minimum threshold voltage and the maximum threshold voltage to the comparator.
    [0050] According to one implementation of this example, the power circuit comprises a regulator and two capacitors for powering the operational amplifier of the Schmitt trigger assembly.
    [0051] According to a third embodiment, the transformer supply is of the flyback type (return) comprising a transformer comprising the primary coil and the secondary coil and a flyback driver (return) coupled to the transformer to allow isolation between primary and secondary.
    [0052] According to an example, the flyback type transformer comprises on its secondary a terminal connected to the power input of the switch. In this way, the voltage at the secondary terminals of the transformer is between the input power potential and a power terminal of the home automation unit. In this way, when the electronic bypass switch is in the open position, a part of the sector current passes in the supply circuit and another part of the sector current passes through the secondary of the transformer to supply the home automation unit and through that when the electronic bypass switch is in the closed state, it is the storage unit that feeds the primary that feeds the secondary of the transformer to feed the home automation unit.
    [0053] According to a fourth embodiment, the electronic switch further comprises:
    [0054] • a load input connected to the load terminal,
    [0055] • a sector input connected to the sector terminal, • a power input connected to the input terminal, • a power output connected to the output terminal,
    [0056] • a first electronic alternating component to control the current coming from the load terminal to the power input and from the power output to the power terminal. sector,
    [0057] • a second electronic alternating device to control the current coming from the sector terminal to the power input and from the power output to the load terminal,
    [0058] • in which the first and second electronic control members each comprise a control connected to the microcontroller to control them.
    [0059] According to an example of this fourth embodiment, the electronic switch also comprises:
    [0060] • a first branch,
    [0061] • a second branch parallel to the first branch,
    [0062] • a first electronic alternation body comprising:
    [0063] i. on the first branch, a first transistor connected to the power input to control the current from the load terminal to the power input and ii. on the second branch, a first electronic member connected to the power output to allow the current from the power output to pass to the sector terminal and
    [0064] • comprising the second electronic alternating body: i. on the second branch, a first transistor connected to the power input to control the current from the sector terminal to the power input and ii. on the first branch, a second electronic organ connected to the power outlet to pass current from the power outlet to the load terminal.
    [0065] An example of this type of this embodiment makes it possible to have a switch that can comprise only two transistors to be controlled by the microcontroller.
    [0066] In another example that is a variant of the previous example, the electronic switch also comprises:
    [0067] • a first branch,
    [0068] • a second branch parallel to the first branch,
    [0069] • comprising the first electronic alternation body:
    [0070] i. on the first branch, a first transistor connected to the supply output to control the current from the supply output to the sector terminal and ii. on the second branch, a first electronic member connected to the power input to let the current from the charging terminal pass to the power input and
    [0071] • comprising the second electronic alternating body i. on the second branch, a second transistor connected to the supply output to control the current from the supply output to the load terminal and ii. On the first branch, a second electronic organ connected to the power input to allow the current from the sector terminal to pass to the power input. feeding.
    [0072] An example of this type of this embodiment makes it possible to have a switch that can comprise only two transistors to be controlled by the microcontroller.
    [0073] According to a particularity of one of these last two examples of this embodiment, the first electronic member and the second electronic member are each a diode. This allows for a simple and inexpensive switch.
    [0074] According to a variant of the previous feature, the first electronic member and the second electronic member are each a transistor controlled by the microcontroller. This makes it possible to avoid a short circuit in the event of a malfunction of one of the two components of the first or second electronic alternating member.
    [0075] According to an implementation of the first example and of the first feature, the diode of the first alternating electronic member comprises an anode connected to the power output and a cathode connected to a connection node connected to the sector terminal and to the first transistor.
    [0076] According to an implementation of the second example and of the first feature, the diode of the second alternating electronic member comprises an anode connected to the power supply output and a cathode connected to a connection node connected to the load terminal and to the second transistor.
    [0077] According to an example of this embodiment, the microcontroller can control the switch:
    [0078] • in an open state that prevents the supply current from pass through the first and second electronic control unit between its charging terminal and its sector terminal, the device being in an off mode,
    [0079] • in a full-wave power supply state in which the first and second electronic control members are in a closed state during a positive or negative alternation that allows the supply current from the sector to supply the load in full wave;
    [0080] • in a variable state, in which the first and second electronic control elements are controlled to chop the sector supply, which allows the effective nominal voltage of the positive or negative alternation of the sector supply to be reduced to vary the load supply .
    [0081] According to a fifth embodiment, the device further comprises a leakage current supply to supply the home automation unit when the switch is in an open state, the leakage current supply comprising a first terminal connected to the load terminal and a second terminal connected to sector terminal.
    [0082] According to a sixth embodiment, which is a variant of the previous embodiment, the home automation unit controls the switch with a cyclic relationship close to zero to recharge the capacitor when the device is in off mode.
    [0083] According to a seventh embodiment, which is a variant of the fifth embodiment, the power circuit comprises two transistors for connecting the terminals of the transformer in parallel to the switching element. storage to the sector terminal and the load terminal and because the microcontroller controls the transistors in an off mode in a saturated state with a cyclic ratio close to zero so that the average leakage current over a half period is less than a current of intensity mean threshold of the order of <150 ^ A.
    [0084] In this way, this allows the load to be insufficiently powered to function normally. For example, in the case where the load is a lamp, the lamp does not exceed a luminosity that allows the discomfort of a user.
    [0085] According to an eighth embodiment that can be combined with the different previous embodiments, the home automation electronic device is a control device that consumes a lot of energy in the on state. The control unit can also consume a lot of energy in the off state.
    [0086] For example, the control unit is a home automation radio, for example a radio that includes a home automation or standard protocol, such as Wi-Fi / Zigbee in router mode or Bluetooth.
    [0087] By Zigbee in router mode it is understood that the radio allows to receive and transmit information from other home automation devices to another router or to other home automation devices that comprise a Zigbee home automation protocol. A router radio of this type of Zigbee protocol consumes more energy than a simple Zigbee protocol radio to only send or receive information from the home automation device and even more than a Bluetooth type protocol radio.
    [0088] The control unit or the microcontroller is configured to Pair the command device with a mobile application or platform. According to an example of this embodiment, the control member is a man / machine command or control home automation interface.
    [0089] According to an implementation of this example, the human-machine interface is tactile, specifically, tactile with a light-type return (sound, vibratory ...), to allow the user to control the switch.
    [0090] According to a variant, the man-machine interface is a proximity sensor that makes it possible to control the switch in the on state during a user detection.
    [0091] According to another variant of this example, the man-machine interface is a push button, for example on a switch or on an encoder that allows the device to be controlled in an on mode.
    [0092] According to another variant of this example, the man-machine interface is a touch screen that allows the user to control the switch by manipulating the touch screen.
    [0093] According to another example of this eighth embodiment, the electronic control device that consumes a lot of energy comprises a home automation radio comprising a low-consumption Zigbee protocol, as well as a man / machine interface, such as a warning light or several warning lights. warning. Indeed, an electronic member of this type comprises several charges, each one of low consumption, but accumulated they become very energy consumers, specifically, in the on state.
    [0094] According to a ninth embodiment, the home automation electronic device is an information device comprising a home automation man / information machine interface. For example, the interface is a screen or a power consuming warning light in the on state.

    [0108] DETAILED DESCRIPTION
    [0109] [Fig. 2] represents a functional block principle diagram of a first embodiment of a two-wire electronic control home automation device B, connected to a sector S and a load, in this specific case, a lamp L. Lamp L can be a dimmable or non-dimmable lamp. Sector S is an alternating network comprising positive and negative alternations, for example, according to a frequency of 50 Hertz or 60 Hertz or - 10% and according to a nominal effective voltage of 110 Vrms or 230 Vrms or - a 10%.
    [0110] The two-wire electronic control home automation device B comprises a charging terminal BL connected to a terminal of the lamp L and a sector terminal BS connected to a phase of sector S. The other phase of the sector being connected to another terminal of the lamp L. In this way, the home automation device two-wire electronic control unit B comprises only two external terminals to be connected to two wires.
    [0111] The two-wire electronic control home automation device B comprises a switch 2 mounted between the charging terminal BL and the sector terminal BS. Switch 2 makes it possible to vary the effective nominal voltage of a positive alternation or a negative alternation or the two alternations of an alternating period of sector S. The switch 2 comprises an open state also called off state that corresponds to the device in an off mode that performs the function of a mechanical switch in an open state and a full-wave on state that performs the function of a mechanical switch in a closed state. Of course, the switch can also be controlled to vary the RMS nominal voltage of a positive or negative alternation or the two alternations of a period of the alternating power of the sector S. The switch 2 will be explained in more detail in the following.
    [0112] The two-wire electronic control home automation device B comprises a home automation unit 3 comprising a microcontroller 30 to control the electronic switch 2 and an electronic home automation device that consumes a lot of energy, such as an electronic control device that consumes a lot of energy. The electronic control unit is, in this example, a communication unit, in this specific case a home automation radio 31 for receiving and sending information about the two-wire electronic home automation device, for example a wireless radio. Therefore, the home automation radio 31 is connected to the microcontroller 30 so that it can communicate information with an application of a mobile terminal, such as a smartphone or with an Internet platform.
    [0113] In this embodiment, the two-wire electronic control home automation device B comprises a leakage current supply unit 1 connected to the sector terminal BS and the load terminal BL to supply the home automation unit 3 when the switch 2 is on. an off state. In the diagram of principle of figure 2, arrows in bold show the path of the leakage current Ia turned off through the different functional blocks of device B. In this way, it can be seen that the current supply unit of Leak 1 is traversed by this leakage current to power the home automation unit 3 including the microcontroller 30 and the home automation radio 31.
    [0114] The two-wire electronic control home automation device B comprises a power supply unit 4 comprising an input terminal 4E and an output terminal 4S connected to the electronic switch 2, such that, in the full-wave on state, the passage of the Power current I on between sector terminal BS and load terminal BL passes through power unit 4.
    [0115] [Fig. 3] represents the principle diagram of Figure 2, but with arrows in bold that represent the path of the supply current I on. The supply unit 4 comprises a supply circuit 40 described in detail, below, in relation to Figure 5, comprising a transformer supply 400 comprising a primary coil 4000 supplied by the current passing from the sector terminal BS to the charging terminal BL and a secondary coil 4001 to transform this energy to power the home automation unit 3 including the microcontroller 30 and the home automation radio 31.
    [0116] In this way, the transformer supply 400 makes it possible to supply the Home automation unit 3 including the microcontroller 30 while keeping the switch in the full-wave on state, that is, without the switch 2 having to perform an attenuation to divert current that feeds the lamp to power the home automation unit.
    [0117] [Fig. 4] represents a time diagram showing the S sector voltage U, the voltage U_Lamp at the terminals of the lamp L, and the supply current I on through the lamp L when switch 2 is controlled in the full wave on state . The voltage U_Lamp at the lamp terminals L is therefore equal to the voltage U of the sector S minus the voltage of the switch and the voltage of the power supply unit. The home automation device B thus makes it possible for the voltage at the terminals of the lamp L to be regular, that is to say, not clipped.
    [0118] [Fig. 5] represents a second embodiment, the home automation unit 3 also comprises a power supply module 32 that allows the current to be distributed to the home automation radio 31 and to the microcontroller 32 under a VCC voltage that comes either from the secondary coil of the transformer 400 from a voltage potential VccOn, either from the leakage current supply unit 1 from a voltage potential VccOff. Furthermore, the power supply module is, in this specific case, connected to switch 2 to supply it with a current under a potential VccEnergy.
    [0119] [Fig. 6] represents a functional block diagram of a power supply unit 4 of the home automation device B of the embodiment of figure 4 or figure 5.
    [0120] The power supply unit 4 is mounted between a reference potential called "computing reference" and an output potential called "Energy_harvesting_Reference". The supply circuit 40 is mounted between the reference potential and the output potential. The microcontroller 30 comprises an input connected to this reference potential to control the switch 2, specifically, to control a change of state of the switch to sector zero.
    [0121] The supply unit 4 comprises, in addition to the supply circuit 40 comprising the transformer supply 400, an electronic bypass switch 41. The electronic bypass switch 41 comprises a terminal connected to the reference potential and a terminal connected to the output potential and a remote to control it. Therefore, the electronic bypass switch 41 is mounted in parallel with the supply circuit 40. The electronic bypass switch 41 comprises a closed position to short-circuit the supply circuit 40 and an open position to allow the switch 2 to supply the supply. power circuit 40.
    [0122] The supply circuit 40 comprises an energy storage element 401 mounted in parallel to the transformer supply 400.
    [0123] The supply circuit 40 comprises a comparator 402 that compares a voltage Vdetec between the output potential and an input of the comparator 402 that is a function of a voltage at the terminals of the storage element 401 called in the continuation supply voltage Vcc_E_H, with a maximum threshold voltage Vmax and a minimum threshold voltage Vmin represented in the time diagram of figure 7 described below. The comparator 402 comprises a signal output connected to the control of the electronic bypass switch 41.
    [0124] When the voltage Vdetec is a function of the supply voltage Vcc_E_H has reached the minimum threshold voltage Vmin, the comparator 402 transmits a voltage at its signal output equal to a voltage at its negative terminal between the output potential and the output to control the electronic bypass switch 41 in the open position. With the electronic bypass switch 41 in the open position, the I-on supply current is divided through the transformer supply 400 and through the storage element 401 which recharges it to a charged state that corresponds to Vdetec equal to the maximum threshold voltage. Vmax.
    [0125] The voltage at the terminal of the storage element 401 increases and when the voltage Vdetec as a function of the supply voltage Vcc_E_H of the storage element 401 has reached the maximum threshold voltage Vmax, the comparator 402 transmits a voltage at its signal output equal to a voltage at its positive terminal between the output and the output potential to control the electronic bypass switch 41 in the closed position. Therefore, the supply circuit 40 is short-circuited and the storage element 401 is discharged by supplying the transformer 400, which thus decreases the supply voltage Vcc_E_H at its terminals to a discharged state that corresponds to Vdetec equal to the voltage minimum threshold Vmin.
    [0126] The supply circuit 40 comprises in this embodiment a voltage level sensor 403 of the energy storage element 401 to supply the voltage Vdetec as a function of the voltage at the terminals of the storage element 401.
    [0127] The supply circuit 40 further comprises, in this embodiment, a comparator supply 404 to supply the comparator. 402 according to a voltage of, for example, 5 V between the output potential and the supply of comparator 404. In this way, the comparator 402 can transmit a signal of 5 V, for example, to the electronic bypass switch 41 to control it in the closed position.
    [0128] The power supply circuit 40 further comprises, in this embodiment, a threshold voltage supplier 405 that allows transmitting a reference voltage Vref to the comparator, so that at the comparator output when Vdetec is lower than the minimum threshold voltage Vmin, the The voltage at the comparator output is equal to the voltage corresponding to the positive supply of the comparator, in this specific case, 5 V, until the voltage Vdetec reaches the maximum threshold voltage Vmax. The threshold voltage supplier 405 supplies a voltage Vref such that the electronic bypass switch 41 is in an open position having at its command the voltage of the output potential that corresponds to the potential energie_havesting_reference, that is, the potential at the output terminal 4S .
    [0129] The supply circuit 40 further comprises in this embodiment a voltage rectifier 406. The voltage rectifier 406 makes it possible to bias the supply current of the supply circuit 40. In this way, the supply of the supply circuit is continuous.
    [0130] [Fig. 7] represents a time diagram that represents a current Mmpa through the lamp corresponding to I on, the voltage Veh at the terminals of the electronic bypass switch 41 and the voltage Vdetec which is a function of the supply voltage Vcc_E_H of the storage element 401.
    [0131] Thus, when the electronic bypass switch 41 is on closed position, the voltage Veh is zero and when the electronic bypass switch 41 is in the open position, the voltage Veh is equal to a voltage at the terminals of the power circuit 40 subtracted from the voltage at the terminals of the voltage rectifier 406 It can be seen from this time diagram that the current Mamma has a sinusoid shape coming from the uninterrupted S sector.
    [0132] Furthermore, when the electronic bypass switch 41 is in the open position, the voltage Vdetec increases and when it reaches the maximum threshold voltage Vmax, the electronic bypass switch 41 goes from the open position to the closed position and the voltage Vdetec decreases to the minimum threshold voltage Vmin, which drives the passage from the closed position to the open position of the electronic bypass switch 41.
    [0133] [Fig. 8] represents a block diagram of an example of the second embodiment of device B comprising an electronic block diagram of the power supply circuit of FIG. 5 and of the functional blocks.
    [0134] The home automation device B of FIG. 8 therefore comprises the power supply module 32.
    [0135] The electronic switch 2 comprises, in this specific case, in these two embodiments, a first electronic alternating member to control the current coming from the charging terminal BL towards the power input 4E and from the power output 4S towards the sector terminal BS and a second electronic alternating member to control the current coming from the sector terminal BS towards the supply input 4E and from the supply output 4S towards the load terminal BL. The first and second electronic control member each comprises a Vmand control connected to the microcontroller to control them.
    [0136] The electronic switch 2 comprises, in this example, a first branch and a second branch in parallel to the first branch. The first electronic alternating member comprises on the first branch, a first transistor M1 connected to the power input 4E and a sector input 2S connected to the sector terminal BS to control the current from the sector terminal BS towards the power input 4E and on the second branch a first electronic member D1 connected to the supply output 4S and to a load input 2L connected to the load terminal BL to allow the current to pass only from the supply output 4S to the load terminal BL. The second electronic alternating member comprises on the second branch, a second transistor M2 connected to the power input 4E and to the lamp input 2L to control the current from the charging terminal BS towards the power input 4E and on the first branch a second electronic member D2 connected to the supply output 4S and to the sector input 2S to allow current to pass only from the supply output 4S to the sector terminal BS.
    [0137] In this example, in this specific case, the first and second electronic components are diodes D1, D2, each comprising an anode connected to the supply output 4S and a cathode connected, for the first diode D1, to the input for load 2L that forms a node that connects the second transistor M2 to the load terminal BL, for the second diode D2, to the input of sector 2S that forms a node that connects the first transistor M1 and the sector terminal BS.
    [0138] The supply circuit 40 comprises, in this example, a flyback type transformer supply 400 comprising a transformer comprising the primary coil 4000 and the secondary coil 4001 and a flyback driver 4002 coupled to the transformer. .
    [0139] The flyback type transformer power supply 400 comprises on its secondary a terminal connected to the power input of the switch 2. In this way, the voltage at the secondary terminals of the transformer 400 is comprised between the input power potential "computing_reference" and the VccOn power potential of the home automation unit 3.
    [0140] In this example, the electronic bypass switch 41 comprises a transistor M3 that allows in a saturated state to be in the closed position and in a blocked state to be in the open position. The transistors M1, M2, M3 are, in this specific case, in this example, NMOS transistors.
    [0141] In this example, the electronic bypass switch 41 also comprises, in this specific case, a bidirectional Zener diode D4 in parallel with the bypass transistor M3 to protect it against overvoltages.
    [0142] The electronic bypass switch 41 also comprises a resistor R7 connected to the control terminal of the transistor M3 and to the comparator 402 to allow limiting a control current in the control as a function of the output voltage of the comparator 402. This allows limiting a degradation of comparator 402.
    [0143] The voltage rectifier 406 of the supply circuit 40 comprises, in this example, a supply terminal connected to the input terminal 4E, a diode D5 and a resistor R1 mounted between the input potential of the input terminal 4E and the anode of diode D5. This makes it possible to restrict the direction of the current in the supply circuit 40 and thus prevent current originating, for example, from the energy storage element 401 from being discharged through the supply terminal of the supply circuit 40. cathode of diode D5 is connected to the flyback type transformer supply, to the energy storage element 401 which is, in this specific case, a capacitor C1, to the voltage level sensor 403 which is mounted in parallel to capacitor C1 and to comparator supply 404.
    [0144] The comparator supply 404 comprises, in this example, a regulator U3 which is, in this specific case, a fixed regulator and two filter capacitors C5 and C6 connected together to a terminal Gnd of the regulator. The two capacitors C5 and C6 each comprise a terminal connected respectively to the input and the output of the regulator U3.
    [0145] The voltage level sensor 403 comprises, in this example, a Zener diode D6 and a resistor R2 mounted between the Zener diode D6 and the potential of the supply output 4S. The cathode of diode D5 is connected to the cathode of zener diode D6. The reference voltage Vdetec is, in this way, at the terminals of the resistor R2.
    [0146] The threshold voltage supplier 405 is mounted between the output potential and the output of the regulator U3. The threshold voltage supplier 403 comprises, in this specific case, two resistors R8 and R3 connected in series and a capacitor C4 in parallel to resistor R3, that is, between the output potential and the potential between the two resistors that correspond to the voltage Vref.
    [0147] According to an example of this embodiment, the comparator 402 comprises at least one operational amplifier U2.
    [0148] According to an example of this embodiment, the comparator 402 comprises a non-inverted Schmitt trigger assembly.
    [0149] The non-inverted Schmitt trigger comparator 402 therefore comprises a resistor R5 between its output and its positive input, a resistor R4 that has a terminal connected to the positive input that comprises at its input the voltage Vdetec corresponding to the input voltage of a Schmitt trigger assembly. Resistor R2 and zener diode D6 of the voltage level sensor are connected to another terminal of resistor R4. The voltage Vdetec, in this example, is therefore an image of the voltage across the terminals of the capacitor C1 in parallel to the voltage sensor 403.
    [0150] In this particular case, the resistor R7 of the electronic bypass switch 41 is therefore mounted between the output of the operational amplifier U2 of the Schmitt trigger comparator and the control of the bypass transistor M3. In this way, the resistor R7 makes it possible, depending on the output voltage of the operational amplifier U2, to supply the current necessary for the transistor to pass in a saturated state or an insufficient current to pass the transistor to the blocked state.
    [0151] Naturally, the invention is not limited to the embodiments described with reference to the figures and variants could be considered without departing from the scope of the invention.
