Design and Optimization of Capacitive Device for Electromechanical Servo Power Supply System

飞行器机电伺服设备中,为了提高供电效率和动态响应,在伺服动力电母线并联容性装置。现有母线容性装置组成简单、功能单一,已经不能满足现阶段的试验及地测需求。对母线容性装置进行优化,增加电荷自卸载电路,提高伺服电能响应速度的同时,增加伺服电源供电稳定性、降低逆变桥的尖峰电压、提高操作及测试安全性。

In order to improve the power supply efficiency and dynamic response of electromechanical servo equipment of aircraft,capacitive devices are paralleled in servo power bus.The existing capacitive devices are simple in composition and single in function,which cannot meet the needs of the current test and geological survey.This research optimizes the bus capacitive device,increases the charge unloading circuit,improves the servo power response speed,increases the stability of the servo power supply,reduces the peak voltage of the inverter arm,and improves the operation safety.
