Three Switch Three Phase Inverter With Improved DC Voltage Utilization
, 2019 This paper proposes a new DC-AC converter with a less number of semiconductor switches and therefore gate drive and control circuit components. A salient feature of this inverter is its pure sinusoidal line-to-line voltages with no need for output filter.
