【Abstract】 Based on analysis of the three-phase four-wire active power filter(APF),this paper established a mathematical model of three-leg mid-point capacitor inverter,and by introducing soft switching technology,using the improved ip-iq detection circuit,designed a new type three-phase four-wire APF.Through Matlab/Simulink simulation,the simulation waveform shows that the scheme has good performance of harmonic suppression.The cost and power consumption of the new filtering equipment are decreased greatly.更多还原
