Description
Summary:A new multilevel space vector PWM technique is proposed for high power applications. The technique is developed for H-bridge series-connected multilevel inverters. A phase-shift between space vectors produced by power cells is used for harmonic suppression. As a result, hardware and software implementation is greatly simplified. The phase-shift concept has been verified by simulations and experiments with a two-cell (five-level) series-connected voltage inverter with a space vector PWM. The proposed technique can be easily extended to higher level inverters.
