Abstract
Two switching circuits are connected between the gate and the source electrode of a field effect transistor, each of said circuits comprising a controlled switch and a secondary winding of a pulse transformer. A first pulse generator produces at a predetermined rate a pulse having a first logic state for driving the controlled switch of a first of said switching circuits, said pulse being applied to a transformer primary winding, and a second pulse generator produces at a predetermined rate a pulse having a second logic state which is complementary to the logic state of the pulse produced by the first pulse generator, for driving the controlled switch of the second switching circuit, each primary winding being magnetically coupled with a secondary winding.
