Abstract: A switch recovery circuit is disclosed for improving the efficiency of switching voltage regulators. The switch recovery circuit includes a first and second inductor, a capacitor, a first diode, and a recovery circuit. The capacitor and diode comprise an AC coupled loop circuit around the first inductor. Current flows through the loop circuit soon after the switch is opened and charges the capacitor. The recovery circuit, which includes a second inductor that is magnetically coupled to the first inductor, provides current, at least some of which discharges the capacitor (i.e. current that flows in the opposite direction to the loop current) after the loop current stops. A second diode is interposed in series with the second inductor to provide appropriate voltage offsets in the circuit and to prevent the first inductor from being shorted to ground through the second inductor.
