FIELD: electricity.
SUBSTANCE: independent electric power supply system of space vehicle includes solar battery consisting of solar elements and in-series connected blocking diodes, constant-voltage unit connected between solar battery and load, accumulator battery, charging device and discharge device. One of inputs of accumulator battery is connected to output of charging device and to input of discharge device. Input of charging device is connected to solar battery. Output of discharge device is connected to solar battery and to input of constant-voltage unit. Second outputs of solar battery, accumulator battery and load are connected to common bus. Input of charging device is connected to solar battery between solar elements and blocking diodes.
EFFECT: increasing efficiency of using the primary restricted power source.
