Three-phase, Five-level Multi-level Inverter Topology

Abstract This article reports a three-phase multilevel inverter topology. The multilevel inverter configuration generates voltage levels similar to the corresponding well-known conventional diode-clamped, flying capacitors and cascaded H-bridge inverters but with fewer power circuit components and simplicity. By optimizing the proposed switching patterns through analysis, the total harmonic distortion of the inverter output line voltage waveforms have been reduced. The validity of the proposed cascaded multilevel inverter is verified through simulation and experiments.
