In this paper, the authors proposed a simulation of three phases nine level inverter fed induction motor drive. Various low quality of power a conventional inverter fed induction machine is due to the presence of harmonics and significant level of energy is loss. The proposed nine level inverter is used to reduce the harmonics. These inverters are used to generate high quality voltage waveforms. The voltage reference can follow accuracy in nine levels and the befit is to generate voltage can be modulated instead of PWM.
