Abstract：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.
