Abstract
A switching circuit for conducting a pulse of current between a first and a second terminal, the circuit including a transistor having a base connected to the first terminal, an emitter and a collector and a saturable-core transformer having an emitter winding coupling the emitter to the first terminal and a collector winding coupling the second terminal to the collector so as to provide regenerative current feedback rapidly driving the transistor into saturation after the transistor is suitably triggered, the circuit diverting the collector current from the emitter to the base circuit sweeping carriers out of the base and hastening the transistor turn-off after the transformer core saturates decoupling the emitter and collector windings.
