A Switching Frequency Optimized Space Vector Pulse Width Modulation (SVPWM) Scheme for Cascaded Multilevel Inverters

This paper presents a novel switching frequency optimized space vector pulse width modulation (SVPWM) scheme for cascaded multilevel inverters. The proposed SVPWM is developed in a α′β′ coordinate system, in which the voltage vectors have only integer entries and the absolute increment of coordinate values between adjacent vectors is equal to dc-bus voltage of power cells (1 pu). The new SVPWM ...

Multilevel Inverters Based On Space Vector Pulse Width Modulation Technique

In this paper, a simplified space–vector pulse width modulation technique for multilevel inverters is proposed. This method is based on the simplification of the space–vector diagram of a five level inverter into that of a three level inverter. In turn, the three level inverter space vector diagram is simplified into that of two level inverter. Hence, the algorithm of five level space-vector pu...
