Abstract
An energy recovery circuit receives and stores energy associated with switching transitions in a power converter having a first switch and a second switch configured to be operated to selectively apply a voltage source to an output load. The energy recovery circuit includes an inductive element, a diode, and a capacitive element. The inductive element receives at least a portion of electrical current flowing through one of the first switch and the second switch. The at least a portion of the electrical current flows through the diode to charge the capacitive element with a voltage. The energy recovery circuit includes a recovery power converter to transfer the voltage from the capacitor.
