针对卫星电源工作环境恶劣的特点,提出了一种对基于HE-Boost放电电路进行稳健性设计与优化的方法。在电路设计方面,基于某卫星实际情况,采用跨导控制方式,并对其建模分析,得到相应传函与参数;在优化与可靠性方面,采用稳健性设计:通过对电路进行灵敏度及参数扫描分析,实现参数优化;通过应力分析、最坏情况分析以及模拟一种故障模式,验证元器件在一定范围内变动或失效时,多模块并联电路的母线电压依旧稳定。综上,该方法适用于卫星电源电路等对可靠性要求较高的场所。
Aiming at the poor working environment of satellite power supply, a method of robust design and optimization based on HE-Boost discharge circuit is proposed. In the circuit design, based on the actual situation of a satellite, the transconductance control method is adopted, and its modeling and analysis are conducted, and the corresponding communication and parameters are obtained. In terms of optimization and reliability, the robust design is adopted: the sensitivity and parameters Scan analysis to achieve parameter optimization; through the stress analysis, the worst case analysis and simulation of a failure mode to verify component changes or failure within a certain range, the multi-module parallel circuit bus voltage is still stable. In summary, the method is suitable for satellite power supply circuits and other places with high reliability requirements.
