ABSTRACT:
A circuit for holding the voltage across a rapidly switched semiconductor element such as a transistor used in an inductive circuit to substantially twice the voltage of an input source when the element is switched to its nonconducting state. Also included is circuitry for recovering and returning to the input source the energy stored in the inductance and wiring of the inductive circuit.
