摘　　要：针对无法使用传统非隔离型航天器电源系统的设计问题,提出了一种航天器用新型隔离充电器设计方法。首先通过电路工作时序图,详细分析了所提电路的工作原理,并给出了电路关键工作波形,同时针对锂离子蓄电池的充电特性,深入探讨了新型隔离充电器的控制策略件。最后通过实验电路验证了所提出的隔离电源拓扑的可行性与有效性,为航天器电源系统的设计提供了参考。In order to solve the problem that the traditional non-isolated methods couldn＇t be used in the design ofspacecraft power system, a new isolated charger for spacecraft was presented. The operating sequence diagramwas presented, and the operating principle of the charger was analyzed in detail with the key waveforms. Moreover,based on the charging characters of lithium ion battery, the control strategy was described. Finally, an experimentcircuit verifies the feasibility and effectiveness of the new converter topology, which provides a reference instructionfor the spacecraft power system design.
