METHOD FOR DC SUPPLY TO LOAD IN AUTONOMOUS POWER SUPPLY SYSTEM OF ARTIFICIAL EARTH SATELLITE Russian patent published in 2010 - IPC H02J7/02 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering industry and may be used to create autonomous power supply systems of artificial Earth satellites (AES). Method for DC supply to load in autonomous power supply system of artificial Earth satellite with several rated values of output voltage, from the primary source of limited capacity, for instance solar battery, and secondary source of electric energy, for instance accumulator battery, consists in stabilisation of voltage on the load and matching of operation of primary and secondary sources of electric energy, besides at first voltage is stablised on the load having maximum output voltage of supply by means of parallel stabilised converter, comprising control circuit with width-pulse modulator, and stabilisation of voltage in other loads is done from supply busbars of the first load by service stabilised converters. Matching of operation of primary and secondary sources of electric energy is done only at the first level of voltage stabilisation. Primary source of electric energy is divided into permanently connected main and switched additional sections, at the same time capacity of the main section of primary source of electric energy is selected by capacity of duty mode based on established ratio, and additional sections of primary source of electric energy with capacity of each section that does not exceed capacity of the main section of primary sources of electric energy, are connected when capacity of the main section is not sufficient, at the same time capacity of parallel stabilised converter is calculated based on capacity of the main section of primary sources of electric energy. Besides connection and disconnection of additional sections in primary source of electric energy is done by extreme integral levels of signals from the outlet of width-pulse modulator of control circuit in parallel stabilised converter.

EFFECT: improved specific power characteristics of autonomous power supply system of AES.
