WE Inverter

This paper proposes a reduced switch count WEtype inverter topology that employs one DC source, nine IGBTs, and one AC-switch comprising of two antiparallel IGBTs, and two capacitors. It is capable of generating 1.5 times boosted 13- level output voltage and employs modified Nearest Level Control (NLC), which considers both zero states. An algorithm based on redundant states controls the voltage across the auxiliary DClink at Vdc/2.
