A High Gain DC-DC Full-Bridge Converter With Integrated Passive Snubber Network

High gain DC-DC converters have become increasingly popular in recent years as there is greater need to interface low voltage DC sources such as solar cells and batteries with much higher voltage DC buses. A new high gain DC-DC converter with high gain, galvanic isolation and an integrated passive snubber network is proposed in the paper. In the paper, the general operation of the converter is discussed, its modes of operation are explained and its features are reviewed. The design of the converter is discussed and a set of general guidelines that can be used in the design are presented. The feasibility of the converter is confirmed with experimental results obtained from a prototype converter.
