- With the development of power electronics technology and devices, PWM inverter has been widely used and its fundamental principles have become a new chapter in power electronics course. Three-phase PWM inverter is an important part of motor drive system, the output voltage is composed of differential mode voltage and common mode voltage. The power is transmitted on the basis of differential mode voltage. The current generated by the common mode voltage will consume unfavorable power when it flows through load. However, the impact and analysis of common mode voltage has not attracted enough attention in the teaching of power electronics compared to differential mode voltage. In this paper, software method is used to study the effect of the suppression strategies of common mode voltage. The basic idea is to improve the modulation algorithm and the control of the non zero vector. The traditional SVPWM modulation strategy and several SVPWM based non zero vector PWM (NZPWM) strategies are compared, and then implemented in MATLAB/SIMULINK environment. Finally, the suppression effect on common mode voltage of different strategies is analyzed.
