航天供配电系统舵机负载浪涌抑制策略研究

随着航天器供配电系统的快速发展，大功率机电负载的使用逐渐增多，对其负载供电品质的要求也日益严格。针对高压大功率舵机负载工作状态变化大、要求响应快、动态指标高，导致机电舵机负载在工作过程中会频繁出现换向、加减速的工作特点，对电动舵机高速制动过程中产生的反灌能量进行供配电系统影响分析，提出供配电系统反灌浪涌抑制策略，提升供配电系统供电可靠性，确保航天器飞行任务中舵机负载的全程可靠运行。

Research on Reverse Surge Suppression Strategy of Steering Gear in Aerospace Power Supply and Distribution System

With the rapid development of spacecraft power distribution system, high power electromechanical loads are widely used, and the power supply quality of high-power electromechanical loads are increasingly 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 commutation, 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.
