摘　　要：针对模块化多电平换流器(MMC)运行中存在环流的问题,提出一种结合陷波器和准比例谐振控制器环流抑制策略。在MATLAB/Simulink平台搭建环流抑制模型进行仿真,仿真结果表明该方法有效抑制环流,降低了桥臂电流的畸变率。Aiming at the problem of circulating current in the operation of modular multilevel converter(MMC),a loop suppression control strategy combining notch filter and quasi-proportional resonance controller is proposed.The model is built on MATLAB/Simulink platform for simulation.The simulation results show that the method effectively suppresses the circulating current and effectively reduces the distortion of the bridge arm current.
