In this paper, a novel multilevel strategy based on a signal slicing technique, and that employs phase-shifted carrier is presented for the design of SPWM inverters. The method relies on slicing the reference signal into various segments, carriermodulates each segment independently, and multiplexes the carrier modulated slices in amplitudes. The resulting multilevel SPWM switching patterns provide a higher dynamic range than what has been reported in the literature. MatLab simulations have been carried out to…
