Abstract: An electronic switching device comprises a first bipolar junction transistor (BJT) (2a) 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 (2a) and adapted to establish a supply voltage across a capacitor (5) by storing in the capacitor (5) charge carriers accumulated in the base of the first BJT (2a) during application of a base drive current, the quantity of accumulated charge carriers depending on the base drive current; and a controllable current source (4) adapted to control the base drive current, thereby controlling the supply voltage.
