    The invention relates to electrical engineering and can be used in the power supply of control and regulation devices. The purpose of the invention is to expand the functionality and improve the weight and size of the device. After supplying the input DC voltage, the storage capacitors (K) 1, 2 are charged through the charging resistors 5, 6 until the voltage on them reaches the breakdown voltage of the diodes (D) 3, 4 Zener. In this way, a high-voltage inverter is prepared for switching on. With an increase in the inverter oscillations, the current passes through the primary winding of the current transformer (CT) 12 and K 1, K 2 is recharged. The limiter 13 is designed so that the constant bridge voltage on the diodes D (7-10) does not reach the breakdown voltage DZ and D4. The high-voltage inverter is provided with a blocking device, which is turned off when the charging voltage of K1, K2 is sufficient. The goal is achieved by shunting the primary winding of the TT12 with the power circuit of a controllable key connected to the diagonal of the alternating current of the bridge D7 - D10. 1 il. w O5 CD With

    The invention is mainly used in the power supply of control and regulating devices in high-current electronics devices, in particular in devices with forced commutation.
    For the operation of the control electronics of a valve-type current-switching converter with forced commutation, an electrical voltage is required, which is usually supplied from batteries or from devices with mains supply. The disadvantage in this case is that a charged battery or an additional power grid is needed to start up the gate converter. In addition, the operating voltage dp of the control electronics can be obtained through the additional resistance 1
    from the side of strong currents of the valve control electronics of the valve
    current converter.
    Known technical solutions, in which the energy dp control comes from a transformer that feeds in turn from the valve 25 current bodies, and the energy dp is a current transformer (USSR author's certificate No. 598212, cl. N 02 H 1/08, 1978).
    These known technical solutions have the following disadvantages. Batteries require a lot of supervision, and especially when starting to move vehicles are not always ready for use; besides, it is not possible to use batteries in all cases. Additional electrical networks required for supplying control electronics are not always available, especially in vehicles or mobile units. Receiving current through additional transformers incurs large losses and therefore they cannot be applied with a large required power of the control electronics.
    A known unit dp for power supply of control electronics of forced current transformers with forced commutation, containing knots of control and regulating devices, is extracted at the desired point from the forced current commutator.
    30 The goal is achieved by the fact that in the unit for power supply of control electronics of valve current transducers with forced commutation, containing storage capacitors connected to a threshold element, respectively, connected to at least one current transformer, a control key connected to a diode
    40 to the bridge, the winding of the current transformer, shunted by the power circuit of the controlled key, is connected to the diagonal of the alternating current of the diode bridge. In accordance with the invention, the problem is solved in such a way that one or several transfer capacitors, 50 current formers, which are connected to at least one element, are connected to one or several switching circuits of a gate-mounted current transducer with forced switching. at least one current transformer, a controllable switch connected to a diode bridge.
    However, transformers that are powered by or working with valve current transducers are not always available.

    In addition, the generation of energy through such a transformer is impossible even in those cases when this transformer, powered by or operating together with a valve-type current transformer, operates on a regulated voltage or current, as, for example, is obtained in the case of limiting the current of the tO current converter.
    The invention aims to eliminate these drawbacks and to ensure the supply of control current to valve converters 15 of current with forced switching, which meets the requirements in all cases of operation.
    The basis of the invention is to provide electricity
    current transformers without the aid of batteries, additional power grids and resistors, without transformers powered by valve converters of control and regulating devices are extracted at the desired point from the current transformer with forced switching.
    30 The goal is achieved by the fact that in the unit for power supply of control electronics of valve current transducers with forced commutation, containing storage capacitors connected to the threshold element, respectively, connected to at least one current transformer, a control key connected to a diode
    40 to the bridge, the winding of the current transformer, shunted by the power circuit of the controlled key, is connected to the diagonal of the alternating current of the diode bridge. In accordance with the invention, the problem is solved in such a way that one or more switching circuits of a gate-mounted current converter with forced switching connect one or more conveyors to supply storage capacitors, which in turn receive control energy from the control electronics, and the output windings be short-circuited by controlled or voltage dependent circuit elements.
    Before commissioning the gate converter, the storage capacitors are charged through one or more static resistances; The metering is carried out after the valve converter reaches the operating mode with the energy obtained from the switching circuit of the valve converter.
    The drawing shows a diagram of the proposed unit.
    The unit consists of storage capacitors 1 and 2, Zener diodes 3 and 4, charge resistances 5 and 6, a single-phase bridge diodes 7-10, a baseload resistance 11 and a transformer 12 with Limiter 13, made, for example, on a triac Primary wire of a transformer 12 current is included in the switching circuit of the high-voltage inverter. At the point + Ug is the positive potential of the input DC voltage to be changed; The -Ug point is (in most cases instances) the negative potential of the input DC voltage. At points +1, -and, and O, an auxiliary voltage necessary for the operation of the control electronics can be obtained.
    The unit functions as follows: capacitors connected to
    zom.
    After supplying the input DC voltage, the storage capacitors 1 and 2 are statically charged through the charging resistances 5 and 6 until the voltage on them reaches the breakdown voltage of the Zener diodes 3 and 4. Thus, a high-voltage inverter is prepared for switching on those. energy for the first
    control electronics pulses can be obtained from cumulative

    capacitors 1 and 2. With an increase in the oscillations of the inverter, switching current pulses are supplied through the primary wire of the current transformer 12 and the storage capacitors 1 and 2 are recharged through a single-phase bridge on diodes 7-10. The control electronics is further supplied with energy from the switching circuit of the inverter. Ogra-) 0, the imperfect 13 is so arranged that the constant voltage arising on the single-phase bridge cannot reach the pr-. Zener 3 and 4 diode voltage.
    A blockage (not shown) related to the control electronics ensures that the turn-on signal of the high-voltage inverter can only be given when the storage capacitors are sufficiently charged.
