Abstract: This paper presents a three-phase AC-AC matrix converter as a frequency converter. Due to continuous increase in the use of electronics converters like AC- AC, AC- DC, DC – AC and DC-DC, there is always a thrust to develop a converter, which generates lesser harmonics, minimum switching losses and high quality desired waveforms across output and input. The matrix converter is modeled as a combined operation of Inverter and Rectifier. In this paper, the focus is to design and Implementation of Matrix Converter (MC) for frequency changing applications .A simple PWM mechanism is proposed to design a mathematical model of three phase Matrix Converter. There is no DC link between rectifier and inverter stage which add up some efficient properties like compact design, bi directional current flow capabilities. A suitable commutation technique is analyzed. Simulation work is done in MATLAB Simulink environment and comparison with mathematical results are presented. 
Keywords: Pulse Width Modulation Matrix Converter, Commutation.
Scope of the Article: Frequency selective surface
