N2 - In this study, a new circuit topology of tapped-inductor DC-DC converter has been introduced, considering the impacts of parasitic elements. The converter is able to provide wide input and wide output voltage range with high efficiency, including buck, boost and buck-boost modes. First, the principle and algorithm of the new converter has been investigated in detail. Then, the power conversion efficiency has been examined under different duty ratios. The voltage gain and efficiency have simultaneously been analysed with various loads. Finally, the experimental results show that the efficiencies of the new topology are high in most ranges, thus verified the correctness of theory and the effectiveness of the proposed topology.
