SPACECRAFT POWER SUPPLY SYSTEM Russian patent published in 2019 - IPC H02J7/34 

FIELD: electrical engineering.

SUBSTANCE: use: in electrical engineering, for power supply of spacecraft. Spacecraft power supply system consists of solar battery connected by its plus and minus buses to voltage stabilizer, accumulator battery connected by its positive and negative buses to input of discharge and output of charging devices, wherein the solar battery voltage stabilizer and the storage battery discharge device are made in the form of bridge inverters with outputs of the transformer and the rectifier or rectifiers by the number of rated values of the output voltage of the power supply system of the spacecraft. Bridge inverter with output transformer and rectifier or rectifiers in number of output voltage ratings of spacecraft power supply system is made in the form of unified module for certain power, and required capacity of loads of spacecraft both from voltage stabilizer of solar battery, and discharge device is provided, if necessary, parallel connection of unified modules, at that outputs of unified modules are connected to each other respectively in parallel.

EFFECT: improved functional reliability of the power supply system.
