This paper displays another three phase multilevel inverter arrangement suitable for open winding induction motor. Altered setup contains stranded three phase voltage source inverters are utilized along with one bi-directional switch in every phase. Because of this switch one extra voltage level presented in every phase. A modified dabble carrier sine PWM modulation scheme (MDCSM) is developed in such way to overcome the complexity of stranded space vector modulation technique. Hear Phase opposition modulation scheme used to reduce THD. Complete model of multilevel inverters created with basic MDCSM in MATLAB programming.
