摘　　要：升压斩波器作为中速磁浮列车车载电网的核心部件,其均衡输出决定了车载电网的稳定性,目前中速磁浮列车同一套DC 440 V电网中升压斩波器电流输出均衡控制采用的是基于偏差控制的被动调节方法,存在超调量和稳态误差较大等问题。文章提出了一种基于PI控制器的升压斩波器电流输出均衡控制方法,通过仿真和列车动态试验验证,该方法能实现各路升压斩波器输出电流的动态平衡,有效提升中速磁浮列车DC 440 V车载电网对负载变化的适应性和安全性。As the core component of the on-board power grid of medium-speed maglev train,the balanced output of the boost chopper determines the stability of the on-board power grid.Currently,the current output balance control of the boost chopper in the same DC 440 V power grid of medium-speed maglev train adopts a passive adjustment method based on deviation control,which has problems such as large overshoot and steadystate error.This paper proposes a current output balance control method for boost chopper based on PI controller.Through simulation and dynamic testing of trains,this method can achieve dynamic balance of the output current of each boost chopper,effectively improving the adaptability and safety of the DC 440 V on-board power grid of medium-speed maglev train to load changes.
