摘要：
This paper proposes a single-phase to three-phase converter. Such configuration is composed of two parallel single-phase rectifiers and a three-phase inverter operating at same frequency of the grid voltage. The proposed topology has advantages over the standard one due to: a) reduced power rating of the rectifier switches, which means switches operating at equivalent power rating; b) reduced costs if the price of switches with different power ratings is higher than the cost of switches with close ratings: and c) fault tolerance in the rectifier circuit. The model of the system is derived and a suitable control strategy, including the PWM technique, is developed. Experimental results are presented, as well.
