In this paper, a matrix converter that connects directly a three phase ac load to a three ac source is modelled using MATLAB & Simulink and its working principles are analysed. The gate signals of the power switches of matrix converter are produced using Venturini Modulation and Optimum Amplitude-Venturini Modulation (OAVM) method. This method provides the amplitude of output voltage up to 86.66% of input voltage, and output currents are sinusoidal. The simulation results obtained from the

Consequently, the designed MATALB & Simulink model can be confidently used for an application which requires a variable ac power of variable voltage and frequency.
