A normally-off bidirectional switch having two gates is connected to a transformer. The transformer has a first winding and a second winding. A first gate bias power supply configured to use power generated at the first winding to supply power for driving one of the gates of the bidirectional switch and a second gate bias power supply configured to use power generated at the second winding to supply power for driving the other gate of the bidirectional switch are provided. |
