| Abstract: | In this article, a novel locomotive charging power supply for ,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 operation principle is explained analyzed in detail, the parameters of the converter are also illustrated. Simulative and experimental results of a 10 kW prototype are included to show the feasibility of the discussed scheme. |
