This paper is deals the Asymmetric cascaded three phase hybrid multilevel inverter for ac motor application. This proposed hybrid three phase inverter is used to diminishes the no of semiconductor device requirement and enhances the power distribution of each H-bridge cell. The Third Harmonics Injection (THIPWM) with sinusoidal pulse width modulation (SPWM) are used to regulate the output voltage of the inverter, further incorporate the Phase disposition (PD) and Alternative Phase Opposition disposition PWM (APOD) techniques. This control technique is applied to minimize the current harmonic and get the better recital of the system. The circuit is simulated using Mat-lab Simu-link. The circuit performance such as THD, line voltage and phase voltage are compared using two hybrid modulation techniques and verified with simulation results.
