Abstract

A new modified command voltage of the third harmonics injected PWM inverter is proposed in overmodulation mode. By analyzing the relationship between the modulation index and the peak of the fundamental component of the modified reference voltage, we can settle the problem in over modulation mode without iteration. Then we can increase the maximum fundamental component of the third harmonic injected PWM inverter comparative to six-step inverter continuously in over modulation mode.
