摘　　要：设计了一款用于国产化现代有轨电车辅助电源系统平台的充电机功率模块。该模块的主电路拓扑采用了基于移相控制的全桥零电压开关(ZVS)变换器和倍流整流(CDR)电路,主控制芯片采用了TMS320F28335。主控制芯片发出的移相脉宽调制(PWM)脉冲控制信号经过IGBT的驱动模块2sc0435T进行功率放大和隔离后传输至IGBT的门极,以实现移相全桥变换器主功率开关的ZVS。在进行了ZVS软开关参数、系统软件和硬件的设计以及系统模型仿真之后,组装了一台实验样机。实验结果表明设计方案正确,软开关效果良好,并将实验样机产品化后推广至市场应用。A power module of the charger is designed for the modern rail traction auxiliary power system platform.The main circuit topology of this module adopts the full-bridge zero voltage switch(ZVS)converter based on phase-shift control and the current doubler rectifier(CDR)circuit,and the main control chip adopts the TMS320F28335.The phase-shift pulse width modulation(PWM)pulse control signal sent by the main control chip is amplified and isolated by the IGBT driver module 2sc0435 T and then transmitted to the IGBT gate level to realize the ZVS of the main power switch of the phase-shift full-bridge converter.After the design of ZVS soft switch parameters,system software and hardware,and system model simulation,an experimental prototype is assembled.The experimental results show that the design scheme is correct and the soft switch effect is good.The experimental prototype is promoted to the market.
