Abstract

A comparison between several commonly used PWM modulation strategies is made, namely Sinusoidal Regular-Sampled Asymmetrical PWM, Regular-Sampled Asymmetrical PWM plus 3rd harmonic injection and Centred Asymmetrical Space Vector PWM, in order to determine which of them leads to a higher voltage waveform quality. It is shown that the first PWM method causes higher harmonic losses and that although 3rd harmonic injection PWM spectrum contains few harmonic terms than Centred Asymmetrical Space Vector PWM, the latter shows less weighted harmonic distortion
