Boost–flyback converter with interleaved input current and output voltage series connection
IET Power Electronics, 2018 This study proposed a high‐gain dc–dc converter with an interleaved current at the input stage and voltage series connection at the output stage. This converter was designed based on the boost–flyback topology, which has as main characteristic high voltage gain.

Analysis of integrated boost-flyback step-up converter
IEE Proceedings - Electric Power Applications, 2005 The operating principles, theoretical analysis, and design methodology of a high-efficiency step-up converter are presented. The integrated boost-flyback converter (IBFC) uses coupled-inductor techniques to achieve high step-up voltage with low duty ratio, and thus the slope compensation circuit is disregarded. The voltage gain and efficiency at steady
