Abstract:Considering the merits of high power density, high efficiency and low EMI, the DC-DC converter with continuous current is competitive in the application of spacecraft. The concept of continuous current push-pull based topology with coupling inductor is proposed in this paper. In order to obtain continuous current, five new push-pull cells are deduced from traditional push-pull cell. According to the novel structure of continuous current push-pull based topology with coupling inductor, the generation rule is proposed and the topologies based on five new push-pull cells are deduced separately. Depending on the condition that the current of bus side is low-ripple, these topologies are chosen as battery discharge regulator(BDR) or battery charge regulator(BCR). The characteristics are compared to provide optimal topology choice for BDR and BCR. Lastly, a prototype based on a generated topology with high voltage gain is designed and made to verify the correctness of theoretical analysis.
