In this p aper, Matrix Converter is which converts the AC to AC in a single stage. The merits of the matrix converter is its able to deliver variable output voltage with unrestricted input and output frequency, the lack of electrolytic capacitors, and the potential to raise the power density, decrease the size, less weight and better input power quality. In whatever way, application of these converters are restricted because of some issues such as different control strategies, high susceptibility to input power disturbances, common mode voltage effects and less voltage transfer ratio. Recently, matrix converters have gained a resurgence of importance due to the improvements in the semiconductor device industry and the increasing of processor technologies, which promises real implementation of matrix converters in the control of drives. The real effect of indirect space vector modulation scheme for very sparse matrix converter performance will be measures by testing of computationally for using indirect space vector modulation strategies with the passive R load and active load .

<p>Matrix converter performs energy conversion by directly connecting input phases with output phases through bidirectional switches. Conventional power converters make use of bulky reactive elements which are subjected to ageing, reduce the system reliability. The matrix converter (MC) stands as an alternative to conventional power converter. Furthermore MC’s provide bidirectional power flow nearly sinusoidal input and sinusoidal output waveform and controllable input power factor. In this work, three modulation methods have been simulated using MATLAB and compared on the basis of input current harmonics, output voltage harmonics and number of switching per cycle.  The three techniques simulated are, Optimal Venturini method, Direct Space Vector Modulation (DSVM) and Indirect Space Vector Modulation (ISVM) on Conventional Matrix Converter (CMC) and obtained form Fuzzy c-Means (FCM).  DSVM with FCM is proposed for obtainting best results compared to other three techniques.</p>
