Control system for a plurality of electric satellite thrusters and electric propulsion device comprising such a control system

摘要

A control system comprises sources of supply, in terms of power and in terms of control signals, capable of equally piloting each of the electric thrusters and further comprises a switching device capable of linking any one of the sources of supply to any one of the electric thrusters. The switching device comprises a rotary main roller divided into a number of angular segments comprising input and output conductive tracks and pre-wired electrical networks linking the input conductive tracks to the output conductive tracks of each angular segment, the pre-wired electrical networks associated with the different angular segments all being different and dedicated to different configurations for the piloting of the electric thrusters by the sources of supply.
