Zusammenfassung:Apparatus for automatically controlling the base current of a power transistor operating in a switching mode. Logic circuit means detect the collector-emitter voltage of the power transistor reaching a critical threshold at turn-on, and impedance feedback circuit means control the minimum conducting and blocking times of the power transistor. Circuit means are also provided to control the switching state of the power transistor and to produce a signal indicative of said switching state, thereby permitting plural power transistors to operate in a parallel arrangement.
