The present application is directed to drive arrangement for semiconductor switches and in particular to a method of driving the gate of a switch with pulses corresponding to turn-on and turn-off commands through separate turn-on and turn-off transformers. The application provides a fail safe reset feature, a more efficient turn-on circuit and an energy recovery circuit for recovering energy from the gate upon turn-off. The application also provides a novel arrangement for assembling multiple pulse transformers on a circuit board.
