Abstract: In this paper, the PWM modulation strategy of the electric vehicle（EV） motor driven inverter was studied, and the PWM principle and optimization type of the motor driven inverter were analyzed.In order to improve the voltage utilization ratio of automobile battery, this paper compared the conventional SPWM modulation technique with the optimized SPWM modulation technique, and proposed a new zero sequence voltage calculation method. In addition, three calculation and generation methods of zero sequence voltage during PWM modulation were simulated.
