Single Phase Matrix Converter with Novel Commutation Strategy

In this paper, a single phase matrix converter circuit with novel commutation technique is proposed. With commercial IGBT modules, the proposed converter is quite compact in structure and easy to build. The applied commutation strategy introduces a simple RC circuit as commutation aid without need for sensing information, leading to stable and reliable operation. The modulation method is explained; the detailed commutation procedure is illustrated. Finally, the simulation results show the validity and verification of the proposed single phase matrix converter.
