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.
