    less than the load is connected in parallel in such a way that at least one power supply unit is redundant. Easy selection
    one
    The invention relates to electrical engineering and can be used in a power supply system including a series of power supply units connected to a common bus for supplying power to a number of electronic devices.
    The purpose of the invention is to increase the reliability, flexibility of the power supply system and reduce the cost of its production.
    FIG. 1 is a block diagram of a power system; FIG. 2 is the same with the specific implementation of two power supply units and a power supply control circuit,,
     The power supply system (Fig. 1) contains power supply units 1-5 connected to a common bus for energizing the load, a power control circuit consisting of voltage control circuits 6-8 and a power supply control circuit 9 connected to the power inputs to a 5-volt bus 10, k24 volt bus 11 and to a common bus 12. Each power supply unit (Fig. 2) consists of an energy source 13, the test output 14 of which is connected to the indicator lamp 15 and to one of the inputs of circuit 16, to the other input of which the output of the inverter is 1 7, the input 18 of which is connected to one from the terminals of the ballast resistor 19, the other terminal of which is connected to the positive terminal of the power supply unit, an additional transistor 20, the base of which is connected to the output of the AND 16 circuit, the emitter to the negative terminal of the power supply unit, and the collector to the inverter input of the subsequent power supply unit, the collector of the transistor 20 of the last power supply unit is connected to the input 21 of the power supply control circuit 9, consisting of the power supply unit 2
    the required number of power supplies allows the power supply system to meet any load conditions. 2 Il.
    a voltage monitor that checks the voltage on tires 10-12 and issues a normal operation signal to terminals 23 and 24 when all voltages are normal, and from the voltage control unit 25, which receives a signal to input 26 and issues a normal operation signal on terminals 27 and 28, when the transistor 20 in all power supply units 1-5
    is electrically conductive. In addition, the input of the inverter 17 of the first power supply unit is connected to the common bus 12.
    The system works as follows.
    I When power supply 1 is operating normally, power source 13 provides a high level signal to test terminal 14, causing the indicator lamp to light up 15. Level O is on
    common bus 12 causes inverter 17 to provide a high output, and thus circuit 16 also provides a high voltage level, which causes transistor 20 to become electrically conductive. If the same operation occurs in the remaining power supply units 2-5, a low level signal appears at the input 21 of the power supply control circuit 9, and the voltage control block 25
    it is detected from input 26 and outputs a normal operation signal to terminals 27 and 28. The voltage control unit 22 detects certain voltages on the Yu-12 tires and supplies a normal operation signal to terminals 23 and 24.
    Suppose that one of the 5 volt power supply units 1-3 had a malfunction, for example, the power source 13 was faulty in block 1, then the signal from the test output 14 goes low, causing the indicator lamp 15 to go out and the transistor 20 turns off. high level at the inverter output
    adjacent power supply, turning its output into a low one and disconnecting the associated transistor. This operation extends to the following power supply units, and finally, input 26 is given a high level, which excludes the output of the normal operation signal to terminals 27 and 28. This operation also takes place in the event of a failure of any power supply unit W or the presence of a malfunction in one or at least the power supply unit can be determined by the absence of a signal of normal operation at terminals 27 and 28, and the failed power supply unit can be immediately determined by the operator by checking the indicator lamps 15 of each power supply unit.
    In addition, in the event that only one of the 5 volt power supply units 1-3 or only one of the 24 volt power supply units 4 and 5 is faulty, the power required for the 6-8 voltage control circuits.
    meet any load conditions with that simple selection of the required number of power supply units, and in the same case, in the event of a failure in one of the power supplies, it can be repaired or replaced without interrupting the load, and can be made highly reliable and at the same time, an expensive power supply system
