Abstract
A drive circuit having a transformer with its secondary winding connected to the base of a transistor and its primary winding connected to a drive source by which the transistor is driven to switch, wherein a directional element is connected between a tap provided on the secondary winding and one end of the secondary winding so as to select the ratio between the forward base current and reverse base current of the transistor.
