Circuit design of an AC drive test system for metro vehicles

文章介绍了地铁车辆交流传动试验系统电气传动主电路,设计了输出直流电压可调的十二脉波整流电路、牵引逆变器电路,并确定了电路中各部件的参数。运行结果表明,整个试验系统运行稳定可靠,各部分工作正常,参数设计合理。

This paper presents an electric drive schematic of an AC drive test system for metro vehicles,in which both an adjustable DC voltage output circuit based on twelve-pulse converter strategy and a traction inverter circuit are designed. Meanwhile, the performance parameters of the components are also determined. The operation results show that the whole test system is stable and reliable.
