Design and implementation of a multi level three-phase inverter with less switches and low output voltage distortion

This paper proposes and describes the design and operational principles of a three-phase three-level nine switch voltage source inverter. The proposed topology consists of three bi-directional switches inserted between the source and the full-bridge power switches of the classical three-phase invert...
