This short paper presents a comparison between high-frequency current-fed full-bridge and half-bridge isolated dc/dc converters with active-clamp snubber. Active-clamp snubber, in addition to absorbing the turn-off voltage spike across the switch, acts as a zero-voltage transition auxiliary circuit resulting in zero-voltage switching (ZVS) of the semiconductor devices of converters. ZVS range depends upon the design, in particular, ratio of leakage and magnetizing inductances of the transformer. Cost, ZVS range, efficiency, volume, components' rating, losses and efficiency, and power density per cell are compared to select a converter.
