Abstract

This paper presents an analytical method that makes it possible to define the pulsewidth modulation (PWM) supply output voltage spectral content, particularly the harmonic phase sequences, without switching instant determination. The results obtained from these developments lead to define a PWM control strategy that allows deleting some switching harmonics in order to reduce undesirable effects. Numerical studies and experiments confirm the theoretical approach and this harmonic control strategy.
