中文摘要：

针对并联型电力有源滤波器电路,研究了零矢量回归方法对设备共模电压的抑制效果,把零矢量回归的三相四桥臂拓扑电路应用到电力有源滤波器中来抑制共模电压,讨论了两种方法对设备本身补偿效果的影响,并利用Matlab/Simulink对理论分析进行验证.

英文摘要：

According to shunt active power filter（APF） circuit, restrain effect of device common voltage with zero vectors recurrence method are researched. Three-phase four-leg topology with zero vectors recurrence method is applied to APF, which restrain the common voltage. The influence to the compensate effect of the two methods are discussed, theoretical analysis are validated with Matlab/Simulink.
