Abstract
An electronic switching device comprises a first bipolar junction transistor (BJT) () adapted to control the flow of current between a pair of switching terminals; a charge recovery circuit coupled to the base of the first BJT () and adapted to establish a supply voltage across a capacitor () by storing in the capacitor () charge carriers accumulated in the base of the first BJT () during application of a base drive current, the quantity of accumulated charge carriers depending on the base drive current; and a controllable current source () adapted to control the base drive current, thereby controlling the supply voltage.
