Dual Switching Mode Scheme for Hybrid Boost-Flyback/ Flyback Photovoltaic Microinverter Applications
IET Power ElectronicsDue to a significantly increase of switching frequency in F mode of boundary conduction mode (BCM) hybrid boost-flyback/flyback (BF/F) microinverter, simply applying discontinuous conduction mode (DCM) to F mode could be an intuitive method to solve this issue but brings a serious distortion in the fixed operation mode transition point, which would ...

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.
