Abstract: A composite switch circuit having a normally-on power switch device and a normally-off power switch device in cascode configuration is discussed. The composite switch circuit is with reduced power loss by biasing a common connection of the source terminal of the normally-on power switch device and the drain terminal of the normally-off power switch device with a low voltage supply during a reverse recovery process of the composite switch circuit.

Abstract: A power switch device with cascode structure provides better performance with simple design. It has a normally-on device and a normally-off device coupled in series. A resistor is coupled to a control terminal of the normally-on device; and a capacitor is coupled between a control terminal of the normally-off device and the control terminal of the normally-on device.
