ABSTRACT:
In a system for energizing the load from a voltage source there is provided a power transistor and regenerative feedback means coupled between a collector and base of the power transistor for only feeding back to the base a signal responsive to an increasing potential sensed at the collector to reduce the time necessary to turn off the power transistor.
