SPACECRAFT POWER SUPPLY SYSTEM

FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering for power supply of spacecraft from primary sources of different power. Spacecraft power supply system comprises: Set of solar batteries of direct solar light (1), Set of solar batteries of reflected solar light (7), generating circuit (8), voltage stabilizer (2), charging device (3), discharge device (4), accumulator battery (5), rectifier (9), accumulator battery charging controller (10) and consumers (6). AC voltage from generating loop (8) is converted into DC in unit (9) and transmitted to the first input of the accumulator battery charging controller (10). Constant voltage from solar batteries of reflected solar light (7) is supplied to the second input of accumulator battery charging controller (10). Total voltage of generating loop and solar batteries of reflected solar light from the first output of controller (10) falls on the second input of accumulator battery (5). First input of accumulator battery (5) receives switches control signals (15-21) from the second output of controller, having contacts 1-3, and switches (22-25), having contacts 1-2. Number of controlled switching devices depends on number of accumulators in battery. For charging selected accumulator (11-14) on associated switches their first contacts open to the third and are closed with the second, on associated switches of the first and second contacts are closed. Connected in such a way to the second input of battery accumulator is charged by nominal current to admission commands from the controller (10) for replacement of another accumulator. Consumer (6) receives power from remaining accumulators bypassing the disconnected, from the first output of battery (5).EFFECT: technical result - increased reliability of power supply.1 cl, 5 dwg Использование: в области электротехники для электроснабжения космических аппаратов от первичных источников разной мощности.
