ABSTRACT:
Bidirectional switches are described. The bidirectional switches include first and a second III-N based high electron mobility transistor. In some embodiments, the source of the first transistor is in electrical contact with a source of the second transistor. In some embodiments, the drain of the first transistor is in electrical contact with a drain of the second transistor. In some embodiments, the two transistors share a drift region and the switch is free of a drain contact between the two transistors. Matrix converters can be formed from the bidirectional switches.
