Multilevel inverters are well used in high power electronic applications because of their ability to generate a very good quality of waveforms, reducing switching frequency, and their low voltage stress across the power devices. This paper presents the Hybrid Pulse Width Modulation (HPWM) strategy base on Sinusoidal PWM (SPWM) and Optimized Harmonics Stepped Waveform (OHSW) of a nine-level asymmetrical inverter. The use of asymmetrical topologies allow to reduce the number of power devices. The HPWM approach is compared to the SPWM strategy. Simulation results demonstrate the better performances and technical advantages of the HPWM controller in feeding a High Power Induction Motor (HPIM).
