Abstract
Exemplary embodiments provide a method and an adaptive RCD snubber circuit for a switching converter having a series-connection of a main inductor and a main switching device. A voltage stress of the main switching device is sensed, and the sensed voltage stress is controlled to a reference level by controlling a snubber capacitor voltage, wherein the snubber capacitor voltage is controlled by adjusting the snubber resistance of the RCD snubber.
