Improvement and reduction of common mode voltage in active zero space vector pulse width modulation in three-phase inverter

This paper describes common mode voltage (CMV) of popular pulse width modulation (PWM) methods for driving three-phase voltage source inverter (VSI). Among PWM methods tested, Active zero space vector PWM (AZSVPWM) provides the minimum CMV. However, study on a switching loss and RMS of CMV in AZSVPWM has been ignored. In this paper, not only studying CMV of popular PWM methods, but also, we propose and verify our method to reduce switching loss or RMS of CMV in AZSVPWM. It is verified by Matlab/Simulink.
