摘　　要：本文分析了机车的辅助供电情况,介绍了目前机车蓄电池组的充电方式,深入研究了目前车载蓄电池组充电器的几种电路结构,并通过对其工作原理和性能的对比分析,指出了这几种方案各自的优缺点。采用新型升降压斩波电路的机车蓄电池组充电器,可以灵活控制机车蓄电池组的充电过程,通过对输出值进行闭环反馈控制,可以达到很高的控制精度,最终实现对蓄电池组的高效充电。Several charging modes of current locomotive are introduced, while some typical circuit structures of current vehicular storage battery set charger are specifically studied. By comparing the work principle and performance of these methods, pros and cons of each solution are concluded. A new vehicular storage battery set charger based on lifting voltage chopping circuit is proposed which can control the charging process flexibly, and acquire high controlling precise by close-loop feedback control of output value and eventually realize the high efficiency charging.
