This paper presents performance of induction motor for five-level and seven-level inverter using cascaded H-bridge topology. Mathematical model of asynchronous motor in d-q reference frame and analysis of five and seven level inverter is done. In this paper the THD values of line and phase voltages of five and seven level inverter and the speed and torque characteristics of induction motor using cascaded H bridge inverters is obtained .Sine PWM technique is used to control the performance of

Using this scheme, we can control the speed and reduces the torque ripples of Induction motor. In this paper software implementation is performed by using MATLAB SIMULINK software.
