ABSTRACT:
First and second gate-controlled switches are connected analogously to a Darlington transistor pair with a slow-response diode connected to delay application of a turn-off signal to the second gate-controlled switch until the first gate-controlled switch is fully turned OFF. The Darlington-type connection reduces a drive current required from a driving source to maintain the second gate-controlled switch fully ON for passing a load current therethrough.
