Abstract

Stepped waveform inverters have the advantages of low harmonic distortion of voltage compared to the ideal sinusoidal waveform. This paper presents a new concept in the realisation of stepped output waveforms by combining, directly, the outputs of several PWM inverters, each fed from the isolated windings of a high frequency DC-DC power converter. The output waveform is optimised to achieve a minimum THD with a given number of switches, operating in any suitable combination of full- or half-bridge inverters. Details regarding the study of such combinations, including experimental verification, is described in the paper
