Abstract

This paper presents a switching strategy for multilevel cascade inverters, based on the space-vector theory. The proposed high-performance strategy generates a voltage vector across the load with minimum error with respect to the sinusoidal reference. In addition, it generates very low harmonic distortion operating with reduced switching frequency, without the use of traditional sinusoidal pulsewidth modulation techniques or more sophisticated vector modulation methods.
