摘　　要：航天器分布式电力系统在运行过程中会遭受各类高能粒子的持续辐射,进而出现性能退化和故障激发,尤其是其集成的关键电力部件一旦发生故障,将严重影响在轨航天器的安全可靠运行。基于航天器上搭载的分布式电力系统,梳理其可能遭受的各种空间辐射环境及常见的辐射效应,探析系统中太阳电池、锂电池、电力电子器件、绝缘材料及电能控制器件等关键部件在辐射环境下的性能退化与故障激发机理,并且基于此机理提出材料、工艺、电路与版图设计、外部防护、软件算法、可靠性评估与故障态势感知等辐射应对策略,最后指出该领域有待开展深入研究的关键问题,为开拓该领域的后续研究提供参考。The distributed power system of spacecraft will suffer continuous radiation from different sorts of high-energy particles during the operation process,which will lead to performance degradation and fault excitation.In particular,once the integrated key power components break down,the safe and reliable operation of spacecraft in orbit will be seriously affected.Based on the distributed power system onboard spacecraft,this paper firstly reviewed various radiation environments and common radiation effects.The performance degradation and fault excitation mechanism of solar cells,lithium batteries,power electronic devices,insulation materials,power control devices and other key components in radiation environment are analyzed.Accordingly,the radiation countermeasures in terms of material,manufacturing process,circuit and layout design,external protection,software algorithm,reliability assessment and fault state perception are proposed.Finally,it points out the key issues to be further studied and provides reference for further research in this field.
