LOAD POWER SUPPLY METHOD BY DIRECT CURRENT Russian patent published in 2015 - IPC H02J7/35 

FIELD: electricity.

SUBSTANCE: invention is related to electrotechnical industry and may be used in creation of autonomous power supply systems (PSS) of communication satellites. At first voltage is limited at busbars of the solar battery by maximum permissible level, thereafter stabilisation of each voltage for n loads is carried out by n series stabilised converters, at that sequencing of operation of the primary and secondary sources of electric energy is carried out at busbars of the solar battery with limited maximum permissible level of voltage. At that voltage at busbars of the solar battery are limited at the level exceeding Uo.p.sb, where Uo.p.sb is voltage of the solar battery at operating point in the beginning of service life at steady temperature, B; a part of the solar battery that does not exceed by power the minimum total power of loads is connected directly to the input of n series stabilised converters while limitation of voltage at the solar battery busbars is made by a parallel stabilised converter.

EFFECT: improved efficiency of use for the primary source of electric energy (solar battery) and specific energy characteristics of the satellite power supply system on the whole.
