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.

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.

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 ...

A Single-Stage Single-Switch Soft-Switching (S6) Boost-Flyback PFC Converter

IEEE Transactions on Power Electronics, 2019
This paper presents a single-stage single-switch soft-switching (S6) power factor correction (PFC) converter to enhance the current shaping performance and reduce the total harmonic distortion. This improvement is achieved by the aid of an auxiliary winding which is used to lower the input current harmonics and also achieve soft-switching condition. As

Highly efficient and compact Sepic-Boost-Flyback integrated converter with multiple outputs

2016 International Conference on Signal Processing, Communication, Power and Embedded System (SCOPES), 2016
This paper proposes a topology of single input multiple-output DC-DC converter by integrating Sepic, Flyback and Boost configuration, whose individual outputs when series connected, results in very high DC-DC conversion ratio. The salient features of the proposed topology are less number of components resulting in a compact structure, less voltage ...

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.
