The two five-levelinverters are fed by both ends of the open-winding inductionmotor. The five-level inverters are connected by cascading offour two-level inverters. This inverter topology does notneutral-point fluctuation so this topology different fromneutral-point clamping inverter and this scheme does not thediode clamping to a fixed neutral point. In the differentmultilevel sinusoidal pulse width modulations used for theproposed topology. The drive is implemented and simulationwith an open-end winding induction motor and simulationresults are presented
