This study reports a three‐phase multilevel inverter (MLI) topology. The MLI 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 optimising 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 cascade MLI is verified through simulation and experiments.
