Abstract
A FET drive circuit is disclosed. The disclosed drive circuit develops a unipolar voltage from a bi-polar source voltage and facilitates fast turn-off of the driven FET. Preferably, the drive circuit includes a first diode having a first reverse recovery time, a transistor, and a second diode having a second reverse recovery time which is longer than the first reverse recovery time.
