Control IC for Boost-Flyback Converter for Energy Harvesting Applications

2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018
Conventionally, 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.

Quadratic Boost-Flyback DC-DC Converter With Coupled Inductors

2018 13th IEEE International Conference on Industry Applications (INDUSCON), 2018
A 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.

A novel sinusoidal boost-flyback CCM/DCM DC-DC converter

2014 IEEE Applied Power Electronics Conference and Exposition - APEC 2014, 2014
This 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.

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 ...

Aggregated modeling and control of integrated boost-flyback high step-up converter

IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011
Integrated boost-flyback converter (IBFC) is constructed with the cascade connection of a boost converter and a flyback converter, it has the advantages of high step-up output voltage and system isolation. Since the boost converter and flyback converter operate in different conduction mode while sharing main switch and dc-link capacitor, a theoretical ...
