Abstract

A common mode voltage (CMV) reduction method is proposed for the active power filter (APF) integrated single-phase quasi-Z-source inverter (qZSI) based photovoltaic (PV) power system. The APF integrated qZSI completely compensates the dc-side double-line-frequency (2ω) ripple through the APF capacitor, while maintaining low qZS inductance and capacitance. The proposed method reduces the CMV amplitude to half of that using the traditional sinusoidal pulsewidth modulation (SPWM). The switching and conduction power losses are analyzed. Simulation and analysis demonstrate the proposed method reduces CMV without loss of performance and efficiency of the APF integrated single-phase qZSI.
