Abstract
A power switching device is disclosed. The power switching device includes a cascode switching circuit comprising a normally-on transistor and a normally-off transistor provided in a cascode topology. The power switching device also includes a gate driver circuit configured to apply a positive bias voltage at a respective gate terminal of the normally-on transistor under a normal operating condition, and to apply a negative bias voltage at the respective gate terminal of the normally-on transistor under a short circuit condition.
