Multilevel PWM Waveform Decomposition and Phase-Shifted Carrier Technique

Abstract:   (13261 Views)
Multilevel PWM waveforms can be decomposed into several multilevel PWM components. Phase-shifted carrier (PSC) is an efficient decomposition technique. In this paper, we have first demonstrated the equality of PSC and alternative phase opposition disposition techniques. Second, we have modified PSC to accommodate other disposition techniques. Third, we have investigated the effects of using asymmetrical carriers on the spectrum of the resulting PWM waveform. Fourth, we have proposed a logical algorithm for decomposing all types of multilevel PWM waveforms.
Keywords: Carrier-Based PWM , Phase-Shifted Carrier , Multilevel Inverters
