Computer simulation of single-phase control rectifier using single-phase matrix converter with reduced switch count

In this paper, single-phase control rectifier using single-phase matrix converter with reduced switch count is proposed. The proposed method is able to perform AC-DC converter operation using only six switches as perform by conventional single-phase matrix converter that uses eight main switches. The PWM technique was used to calculate the switch duty ratio to synthesize the output. Switch commutation arrangements were developed that allows dead time to avoid current spikes of non-ideal switches whilst providing a current path for the inductive load to avoid voltage spikes. The SPMC topology with reduced switch count can be easily control using suitable proposed switching algorithm. The feasibility of the proposed topology was verified by a computer simulation.
