Abstract

See full text

A switching circuit includes a reverse-voltage-blocking (RB) commutation switch, a first inverter leg, and a second inverter leg. The first inverter leg includes a first dual-gate bidirectional (DGBD) and a second DGBD switch connected in series. The second inverter leg includes a third and a fourth DGBD switch connected in series. A pair of the first DGBD switch, the second DGBD switch, the third DGBD switch, and the fourth DGBD switch that are in different inverter legs of the first inverter leg and the second inverter leg are configured to switch between a first DGBD on-state and a second DGBD on-state when in an inverting operating mode. A current with a positive or a negative polarity is conducted when in the first DGBD on-state. When in the second DGBD on-state, a reverse voltage is blocked by and a current with a positive polarity is conducted through the respective DGBD switch.
