Abstract: This paper presents the comparison of performance between matrix converter and conventional DC-link converter fed induction motor drive system. It is noted that conventional converter required two stages for power conversion whereas matrix converter required single stage. The output current from conventional converter contains odd harmonic component which produces additional losses in drive causes de-rating and torque pulsation of motor. This unhealthy operation of drive is reduced by matrix converter which has the unique feature of producing pure sinusoidal output current waveform with minimum harmonic distortion. The main objective of this paper is to reduce total harmonic distortion by employing proper switching of matrix converter. The simulated result is compared with conventional converter to show that proposed system is better than conventional system. This paper also presents modeling and simulation of matrix and conventional converter fed induction motor drive system using MATLAB/SIMULINK software.
