With the rapid development of spacecraft power distribution system,high power electrome-chanical loads are widely used,and the power supply quality of high-power electromechanical loads are in-creasingly strict.In view of the characteristics of high voltage and high-power steering gear load,such as large change in running state,fast response and high dynamic response,which lead to frequent commuta-tion,acceleration and deceleration of steering gear in the working process,and the reverse charge energy generated to the power supply and distribution system during the high-speed braking of the motor,the Reverse surge suppression strategy of the power distribution system is proposed to improve the power supply reliability,ensuring the reliable operation of steering gear in the space-mission.
