Abstract
This paper presents a hybrid PWM method under a low switching frequency based on SVPWM and SHEPWM, which use asynchronous carrier modulation SVPWM at low frequency, and SHEPWM at high frequency, a square wave after rated conditions. The transitive strategy is proposed to realize smooth transition of individual modes including SVPWM, SHEPWM and square wave. Simulation and experimental results confirm this hybrid modulation method and their transition is reasonable and corrected.
