A driver circuit comprising an insulated gate bipolar transistor having a collector coupled to a voltage supply, an emitter coupled to a source of reference potential, and a gate configured to receive a control signal from a driver circuit, and a desaturation circuit conductively coupled between an insulated gate and a collector of the insulated gate bipolar transistor to desaturate the insulated gate. The desaturation circuit includes a series coupled bias voltage source, uni-directionally conducting element and switch.
