Simple delta voltages space vector PWM algorithm for voltage source multilevel inverters

Abstract

The paper deals with the voltage source multilevel inverter space vector PWM algorithm developed on the base of one of the more general algorithms for oblique-angled coordinates of two delta voltages. The symmetry of the instantaneous output voltages on the clock cycle is provided by the simple control for the performing of the preset five-segment switching sequence. The calculations being used are quite simple and fast so they can be performed even applying a cheap DSP.
