摘　　要：本文讨论了一种新型的机车充电电源,这种电源采用一种简单的零电压零电流开关的全桥DC/DC拓扑结构,通过移相控制,在很宽的负载变化范围内实现了软开关,系统工作效率较高。文中对主电路的工作原理进行了简单的分析,并对控制电路的有关参数设计给予了说明,最后给出了仿真波形与一10KW样机的实验波形。In this article, a novel locomotive charging power supply which is formed of a simple zero—voltage zero—current—switching (ZVZCS) full—bridge(FB) DC/DC topology is introduced. The converter could work in a very high efficiency under a wide power load range due to the ZVZCS soft switching operation by phase—shifting control. The principle of operation is explained and analyzed in detail, the parameter of the converter is also illustrated. Simulated and experimental results of a 10KW prototype are included to show the feasibility of the discussed scheme.
