Traction and auxiliary converter systems are two core pieces of equipment in the traction and power supply system of a metro train. It directly determines the performance, efficiency, and operational reliability of the metro train. This paper introduces energy saving traction and auxiliary converter systems for the next generation of subway trains in China. The basic functions of the traction converter system are introduced, and the application of a permanent magnet synchronous motor on the metro train and design of the self-traction system are explained. The topological structure and basic functions of the auxiliary converter system are also introduced. Then, the structure and function of the new high-frequency auxiliary inverter are discussed. The high-performance, high-efficiency, and reliable operation of a metro train can be realized through the comprehensive optimization design of these traction and auxiliary systems.
