Abstract:A kind of isolated bi-directional DC-DC converter based on the single-ended forward converter has been researched in this paper, which has the advantages of simple topology, low loss and high performance. This converter can also be used in the condition of synchronous rectification. Considering the characteristics of the circuit, driving signal waveforms of each switch are analyzed, while the working principle of both forward and reverse mode is introduced. Combining the requests of the system, the methods of choosing the key parameters are given. In order to ensure the efficiency and dynamic response, voltage and current dual-close loop control strategy is adopted in the forward conversion, while single voltage feedback is adopted in the reverse mode. The correctness and feasibility of this converter are verified through simulation tests.
