摘要
应用全桥移相软开关技术设计了轻轨列车用辅助高频DC/DC隔离变换器,并进行了实验分析验证。变换器实现了软开关,并能提高电能变换效率和变换器功率密度。应用软开关高频隔离方案可减小机柜体积,便于设备安装维护等,这也是轻轨列车辅助变流器设备发展的趋势。
With the help of phase-shifted full-bridge soft switching technology,an isolated high-frequency DC/DC converter for auxiliary power unit of light rail vehicle is designed and analyzed,and the experimentally is executed.This converter can achieve soft switching,improve power conversion efficiency,and increase power density of the system.Application of high-frequency soft switching isolation scheme can reduce the volume of the cabinet and easy installation and maintenance.This is the development trend of light rail train auxiliary converter.
