摘　　要：提出了一种基于多电平变流器的并联APF系统的电路拓扑结构,并在交直流控制策略和系统参数设计方面进行了系统的分析。仿真和实验结果表明基于CPS-SPWM技术级联H桥型多电平变流器的SAPF系统能够在较低的器件开关频率下实现较好补偿效果,具有良好的工业应用前景。A shunt APF topology with multilevel converter is presented. AC side and DC side control, system parameter design are discussed. The simulation study is carried out. Simulation and Experiment results have proved that the shunt APF system with cascade multilevel converter based on carrier phase shifted PWM can achieve excellent compensation effect at much low switch frequency, which is of perfect prospect in industry application,
