Design of boost-flyback converter with small capacitor for energy-storage
The 2nd International Symposium on Power Electronics for Distributed Generation Systems, 2010 This 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.

Coexistence of solutions in a boost-flyback converter with current mode control
2017 IEEE 8th Latin American Symposium on Circuits & Systems (LASCAS), 2017 In many practical applications power Converters are designed to work in a desired operation point depending on the needs of the appliance. The ability of the system to work in that point is related to a correct dynamic analysis that eventually leads to de design of a proper control strategy.

Interleaved boost-flyback converter with boundary conduction mode for power factor correction
2011 6th IEEE Conference on Industrial Electronics and Applications, 2011 This paper presents a new interleaved pulse-width modulation (PWM) boost-flyback converter to achieve power factor correction (PFC) and regulate DC bus voltage. The adopted boost-flyback converter has a high voltage conversion ratio to overcome the limit of conventional boost or buck-boost converter with narrow turn-off period.

Soft-switched PWM high-frequency with PFC converter using boost-flyback converter interleaved
24th Annual International Telecommunications Energy Conference, 2003 This 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 ...

High-gain Boost-Boost-Flyback converter for renewable energy sources applications
2015 IEEE 13th Brazilian Power Electronics Conference and 1st Southern Power Electronics Conference (COBEP/SPEC), 2015 In this paper, a non-isolated step-up high-gain DC-DC converter for renewable energy sources applications is proposed. The circuit is composed by a conventional Boost stage and a Boost-Flyback stage, thereby it is possible to attain a high-voltage gain without compromising the converter efficiency.

High power factor integrated buck-boost flyback converter driving multiple outputs
2015 Online International Conference on Green Engineering and Technologies (IC-GET), 2015 This 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.
