POWER SUPPLY AND CONTROL METHOD FOR SPACECRAFT CORRECTION SYSTEM Russian patent published in 2015 - IPC B64G1/24 F03H1/00 

FIELD: electricity.

SUBSTANCE: invention is related to space engineering and may be used for spacecraft correction by means of electric propulsion plasma engines (EPPE). EPPE are selected for switching on, required time of EPPE operation is selected, used and unused electrodes of the engines are selected and connected to the power supply sources by means of contactors, the power supply sources are switched on and off for EPPE start-up and operation within the required period, high-ohmic resistive network if formed for discharge of electric charge from EPPE electrodes to the spacecraft frame, two modes are formed for commutation of the engine electric circuits, the main and reserve power supply sources with capacitive filters are connected to electrodes of non-operating EPPE, electric circuits of the selected EPPE remain connected to the used power supply sources, electric circuits of the other EPPE are switched off from the used power supply sources and still left connected to the unused power supply sources, the used power supply sources are switched on and off in compliance with the defined algorithm.

EFFECT: invention allows increasing reliability of spacecraft correction system.
