| Abstract: | With the help of full-bridge phase-shifted soft switching technology, an isolated high-frequency DC / DC converter for auxiliary power unit of light rail train is designed, analyzed and verified in this paper. The converter can achieve soft switching, improve conversion efficiency of electrical energy and increase power density of APU. The application of the scheme with isolated high-frequency soft switching can reduce the volume of cabinet and it could be convenient for installing and maintaining the devices. This is also the development trend of light-rail train＇s auxiliary converter. |
