摘　　要：介绍了城轨车辆辅助电源系统供电网络采用集中供电与并网供电2种供电方式的结构与特点。其中辅助电源系统逆变器电路拓扑结构有单逆变器与双逆变器2种,前者又有二电平、三电平和高频隔离型3种型式,后者有电路叠加和磁路叠加2种型式。通过分析这2种供电方式的优缺点及各种逆变器拓扑结构的特点,提出应用建议。Structure and features about power supply network of metro vehicle auxiliary power source system including concreting power supply mode and grid connected power supply mode were introduced. The topological structure of auxiliary inverter circuit included two types, i.e. single inverter and double inverter, also the single inverter contained three types including two levels, three levels and high-frequency isolated types, and the double inverter contained two types including the circuit superimposition and the magnetic path superimposition. Analysis of the above mentioned two power supply modes were made for getting their advantages and disadvantages by comparison between them, and the topological structure characteristics of the different types of inverters were supplied, as well as the suggestion was brought up.
