摘　　要：客货两用型的米轨机车对牵引变流器的体积和模块数量有着严格的要求,因此其主电路采用了两重四象限带5个逆变器的模式,并首次将辅助逆变器和列车供电逆变器都集成在牵引变流器中。针对米轨机车牵引变流器主电路的创新设计可能带来的过压、过流等影响,本文以出口马来西亚的Eloco型电力机车为例,对其辅助逆变器和列车供电输出特性进行了仿真研究。仿真结果表明其辅助逆变器和列车供电的控制效果能较好地满足功能需求。Meter-gauge electric locomotive is applicable to passenger and cargo transportation, which has strict requirements for size and module number of traction converter. Therefore, it used a mode of double four-quadrant rectifiers carrying five inverters in the main circuit of traction converter, and firstly integrated auxiliary inverter and train power supply in the main converter. Due to the innovation design of main circuit of traction converter, it may bring impact of over-voltage or over-current faults. Taking Eloco meter-gauge electric locomotive exported to Malaysia as an example, output characteristics of the auxiliary inverter and train power supply were simulated. Simulation results show that control effect of the auxiliary inverter and train power supply can well meet the functional requirements.
