Abstract
A switch device includes at least two bidirectional switches electrically connected in a cascode configuration. A first bidirectional switch and a second bidirectional switch of the at least two bidirectional switches each have a normally-on gate and a normally-off gate. Any remaining bidirectional switch of the at least two bidirectional switches cascoded between the first and second bidirectional switches has a first normally-on gate and a second normally-on gate. The switch device is actively controlled by the normally-off gate of the first bidirectional switch and the normally-off gate of the second bidirectional switch. Each normally-on gate of the at least two bidirectional switches is electrically connected to a source of another one of the at least two bidirectional switches by a voltage blocking device configured to block a portion of the voltage across the switch device when the switch device is off. Additional switch devices embodiments are described.
