Soft-switched PWM high-frequency with PFC converter using boost-flyback converter interleaved
24th Annual International Telecommunications Energy Conference, 2003This paper proposes as a power factor correction pre regulator converter an AC-DC interleaved boost-flyback using a nondissipative snubber and operating at 100 kHz per cell. That is composed by switches working in ZCS and ZVS way, controlled by PWM. By using interleaved converters, an overall reduction of the boost inductor can be obtained, reducing ...

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.

High power factor integrated buck-boost flyback converter driving multiple outputs
2015 Online International Conference on Green Engineering and Technologies (IC-GET), 2015This paper proposes an integrated single-stage ac-to-dc light-emitting-diode (LED) driver circuit. A buck-boost power factor (PF) corrector is integrated with a flyback converter. A recycling path is built to recover the inductive leakage energy. The proposed circuit provides high PF and low total harmonic distortion.

Design of boost-flyback converter with small capacitor for energy-storage
The 2nd International Symposium on Power Electronics for Distributed Generation Systems, 2010This paper presents the idea of utilizing large voltage ripple with small capacitance for energy storage in LED circuit, instead of large capacitance with small voltage ripple. A typical Single-Stage PFC converter with small capacitor is adopted.
