Regenerative and ramping acceleration (rara) snubbers for isolated and tapped-inductor converters

Abstract

A voltage converter circuit comprising a primary inductor; a secondary inductor, at least a portion of the second inductor being mutually coupled to the primary inductor; a rectifier diode connected to the secondary inductor such that the rectifier diode turns off when current flows in the secondary inductor in a first direction; and a snubber circuit arranged to charge a first snubber capacitor with the current flowing through the secondary inductor after the rectifier diode turns off; the snubber circuit being arranged to discharge the first snubber capacitor by complementing the current in the secondary inductor after the flow of the current in the secondary inductor is inverted.
