资料介绍

航天系统设备多,负载特性复杂,产生的瞬态浪涌电流通常对航天飞行器电气系统总体电路的危害很大;为了解决航天飞行器电气系统中瞬态浪涌如何有效抑制的问题,文章从瞬态浪涌形成的原理、影响及测量方法出发,在电气系统总体设计角度,分别从浪涌抑制电路、负载分配策略、负载休眠唤醒工作模式三方面提出了串电阻法、软启动法、负载休眠唤醒法等多种解决方案,通过搭建仿真试验平台和实物试验平台开展了相应的试验验证,瞬态浪涌电流得到了有效抑制.

In space system, there are many equipments whose feature is complex. Inrush current is harmful to electrical system total circuit of spacecraft. In order to solve this problem how to restrain the inrush current of electrical system, the paper firstly introduced principle, influence and measurement methods of the inrush current. Based on the restrain circuit of inrush current, load distribution strategy and load sleep and wake modes, a variety of solutions were proposed, for example, connecting resistance method, slow--startup method, waking load method, etc. The relevant tests were carried out by building simulation test platform and physical test platform, the results showed that inrush current was restrained effectively.
