A Novel Discontinuous Input Current Boost Flyback Converter for LED Applications
2021 2nd International Conference for Emerging Technology (INCET), 2021In this paper a new boost fly back converter is presented. With this converter a discontinuous input current is achieved along with less voltage stress across the switch. In this converter 1:1 transformer is used but the primary side of transformer is having midpoint tapping to connect the capacitors in series and parallel combination to achieve high ...

Charging multiple batteries using the boost-flyback converter
2012 IEEE International Energy Conference and Exhibition (ENERGYCON), 2012A boost-flyback converter was investigated for its ability to charge separate battery stacks from a low-voltage high-current renewable energy source. A low voltage (12V) battery was connected in the boost configuration, and a high voltage (330V) battery stack was connected in the flyback configuration.

Analysis of integrated boost-flyback step-up converter
IEE Proceedings - Electric Power Applications, 2005The 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

Quadratic Boost-Flyback DC-DC Converter With Coupled Inductors
2018 13th IEEE International Conference on Industry Applications (INDUSCON), 2018A high-gain dc-dc converter, which integrates a quadratic boost flyback converter through coupled inductors is proposed in this paper. The integration generates a converter with high-gain using only one switch. The structure allows using the energy stored in the leakage inductance of the first coupled inductor on the load.

Simulation research of boost-flyback photovoltaic grid-connected micro-inverter
2015 Chinese Automation Congress (CAC), 2015Boost-flyback converter can be regarded as a combination of boost and flyback circuit. The leakage inductance of the transformer serves as the energy inductance of boost converter. In this paper, a new strategy which applies boost-flyback topology to a photovoltaic micro-inverter is proposed.

A novel sinusoidal boost-flyback CCM/DCM DC-DC converter
2014 IEEE Applied Power Electronics Conference and Exposition - APEC 2014, 2014This paper proposed a novel and simple sinusoidal boost-flyback continuous conduction mode (CCM) converter. This converter continuously produces half-sinusoidal voltage to a line frequency DC-AC inverter. This simple boost-flyback structure utilizes a coupled inductor to achieve a wider voltage gain range.

Control IC for Boost-Flyback Converter for Energy Harvesting Applications
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018Conventionally, boost converter is used for high step-up energy harvesting system, but it is needed to be operated in discontinuous conduction mode (DCM) because of the limitation of the topology. Therefore, it causes more conduction loss and current stress on the switch.
