Abstract
An apparatus includes a power semiconductor switch, a driver circuit configured to drive a control terminal of the power semiconductor switch, and a control circuit configured to apply a control signal to the driver circuit responsive to a comparison of a reference voltage to a voltage at the control terminal of the semiconductor switch. In some embodiments, the power semiconductor switch may include a field effect transistor (FET), such as a wide bandgap silicon carbide (SiC) MOSFET. The control terminal may include a gate terminal of the FET, and the voltage at the control terminal may include a gate voltage.
