Study of passive filter for application on the single-phase matrix converter (SPMC) operate as AC chopper / Muhammad Azizi Mohd Selam

This paper presents the application of single phase matrix converter (SPMC) as AC chopper by using different type passive filter designs. MATLAB/simulink will be use to develop the simulation model of the SPMC without and with filter and to study the behavior of the proposed converter. Sinusoidal pulse width modulation (SPWM) is used for a switching technique. Safe commutation was developed to avoid voltage spikes. To avoid this kind of problem, filter design represented by low pass RL filter and LC filter. Results of simulation are presented to verify the proposed technique is feasible. The circuit is fed from 50V (rms) and 50Hz supplying a passive R load.
