A Rectification Topology for High-Current Isolated DC-DC Converters

This paper presents a novel current tripler rectification (CTR) topology for secondary-side rectification in high-current low-voltage isolated dc-dc converters. Compared with the conventional center-tapped and current doubler rectifiers, the CTR topology has three filter inductors to share the output current, and thus higher current capability and better thermal management can be achieved. Theoretical analysis and experimental results verify that the proposed CTR is a good candidate for rectification topology in high-current dc-dc converters.
