This paper proposes design and simulation of a Pulse Width Modulation Controlled induction motor and analysis of the fundamental component and the total harmonic distortion using Fast Fourier Transform. The system has studied on different loading conditions with Simulated results are obtained in order to achieve better performance of the Induction Motor for the application of Industrial operations. Here two level pulse width modulator is implemented and the results are discussed. If three level

The version of MATLAB used is R2011b.
