Bidirectional Tapped-inductor Boost-Flyback Converter
The Transactions of the Korean Institute of Power Electronics, 2015 This paper proposes a new bidirectional DC–DC converter with high efficiency. The proposed converter is composed of a flyback and a tapped-inductor boost converter to satisfy extreme operating conditions with low cost. The outputs are connected in series to achieve a high-voltage step-up.

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
