| Summary: | This paper presents the study of a Single - Phase Matrix Converter (SPMC) operated as a single phase AC - DC controller rectifier with safe commutation to ensure that the supply current is continuous, sinusoidal, and in phase with the voltage. The Pulse Width Modulation (PWM) technique as switching was used to calculate the switch duty ratio to synthesize the output. The combination of modified LC-Filter produced good results and avoid voltage spikes. Basic loads represented by R load are used for this investigation. In this work, a simple commutation strategy for the implementation in SPMC provides the required free-wheeling operation similar to those available in other converter topologies is proposed. The commutation strategy used in this work has also shown reduction in spikes, a common phenomenon in matrix converter topologies. The commutation scheme establish a current path for energy to flow during dead-time, the avoiding the generation of voltage spikes. The simulation has been done by using MATLAB/Simulink software to validate the design approach of SPMC. |
