卫星电源放电电路最坏情况仿真分析

Worst case analysis of discharge circuit in satellite power

电源系统作为卫星平台的一个重要组成部分,对保障卫星其他分系统的稳定可靠运行发挥重要的作用。利用Saber软件对卫星电源放电调节模块进行仿真分析,在电路能够实现基本工能基础上,利用蒙特卡洛方法对电路进行了最坏情况分析,用来模拟太空中的不利因素对电路性能产生的影响,并在此基础上提出了电路中的薄弱环节,方便设计人员改善、完善设计。

As a necessary constitute of satellite platform, the power subsystem plays an important role in ensuring the security of other subsystems. Saber software was used to simulate discharge regulator module of satellite power. On the basis of circuit realizing the basic work, Monte Carlo method was used to analyze the worst case, simulating the impact of adverse factors on circuit performance in space. At the same time, finding the weak link is convenience for designer to improve and perfect the design.
