Abstract: Circuits and methods are described for providing gate drive to a gate terminal of a first switching device. The circuit includes a transformer having a core, a primary winding, and at least one secondary winding. The primary winding of the transformer is for coupling to a power source. The at least one secondary winding is for coupling to the gate terminal of the first switching device. A second switching device is connected in series with the primary winding of the transformer. The second switching device controls conduction of current in the primary winding which causes energy to be stored in the core of the transformer. The second switching device is operable to stop the current from flowing in the primary winding thereby causing a current pulse to be generated in the at least one secondary winding from the energy stored in the core. The current pulse is used for driving the gate terminal of the first switching device.
