摘　　要：以轻量化为主线,从供电模式、变流器拓扑结构、新器件应用三个方面,综述了城市轨道交通车辆辅助逆变电源的发展趋势。随着技术的进步,辅助逆变电源朝着轻量化的方向不断改进:采用并联供电方式替代扩展供电和交叉供电,降低整车电源总容量;采用中频化技术,取消工频隔离变压器,降低体积质量;采用碳化硅(Si C)器件替代Si基IGBT(绝缘栅双极晶体管),减小电感、电容、冷却系统的体积质量。以并联供电、中频化技术、新器件应用为代表的轻量化技术是城市轨道交通车辆辅助逆变电源的发展趋势。Recent development of APS is described from perspectivesof parallel operation mode,converter topology anddevices of the next generation.Following technical progress,light-weight design of APS becomes the main developmentdirection for urban rail transit trains.In which,parallel operationmode will replace the extended power supply and thecross power supply to reduce the total capacity of the train,median frequency technology is adopted to replace the powerfrequency isolating transformer,thus the weight of APS will besignificantly reduced.In the future,application of the nextgeneration power devices such as Silicon Carbine(SiC)willreplace the silicon-based IGBT,leading to smaller coolingcomponents,inductors and capacitors.All the light-weighttechnologies represent the development trend of APS.
