Abstract
This paper discusses the comparison method between two type modulation of direct ac - ac matrix converter system with induction motor load. Matrix converter has received considerable interest as a viable alternative to the conventional back-to-back Pulse Width Modulation (PWM) converter in the ac - ac conversion, especially for no load induction motor drive. However, it is not convenient to control the matrix converter. The important point of matrix converter is the modulation technique that has two different technique in Venturini and indirect space vector modulation (ISVM). These methods are compared and analyzed in the total harmonic distortion of output and input to find better performance for induction motor drive. Simulated input and output parameters of matrix converter are presented using Matlab/Simulink software for both modulation techniques. The result reveal smaller total harmonic distortion in ISVM than Venturini modulation for matrix converter.
