Abstract—This paper first introduces several typical topologies of isolated bi-directional DC-DC converter. Based on the analysis and comparison of the main characteristics and applications of each typical topology, this paper presents a novel Buck and Boost topology of isolated Single-ended Forward bi-directional DC-DC converter which has the advantages of compact structure and the adoption of the synchronous rectify. Technique makes the whole system possess the superiority of High efficiency, high control performance and low cost. The circuit structure, working principle, design procedures and analysis in detail are introduced. Experimental waveforms based on UC3875 are given to demonstrate the goodness of this Buck and Boost DC-DC topology.
