METHOD FOR LOAD FEEDING WITH CONSTANT CURRENT IN INDEPENDENT ELECTRICAL POWER SUPPLY SYSTEM OF ARTIFICIAL EARTH SATELLITE Russian patent published in 2014 - IPC H02J7/34 

FIELD: electricity.

SUBSTANCE: method consists in stabilisation of voltage on loads and coordination of operation of primary and secondary electrical energy sources; first, voltage on the load having maximum output supply voltage is stabilised by a parallel stabilised converter, and stabilisation of voltage of the rest loads is performed from power buses of the first load with series stabilised converters; with that, coordination of operation of the primary and secondary electrical energy sources is performed only on the first level of voltage stabilisation. The primary source of restricted power is divided into m sections; a power transistor switch of a short-circuited stabilised converter is divided into m single power transistor switches and each section of the primary source of restricted power is stabilised with the corresponding power transistor switch of the parallel stabilised converter. Control of power transistor switches is performed from a common control circuit with a pulse-width modulator.

EFFECT: improving functional reliability.
