Demonstration of the normally-off bi-directional GaN AC switch

A novel GaN on Si device is presented and tested in an “application like” circuit. The device is a Bi-Directional Normally-Off Switch aimed at AC mains powered applications, it uses a single reference electrode for gating direct and reverse conduction modes. Demonstration of the current collapse free operation of the device under 264V, 3A, 1MHz is presented.
