Designing a hysteresis band in a boost flyback converter

Mechanical Systems and Signal Processing, 2021
Abstract In this paper, we present a method to control a boost flyback converter using a hysteresis band, which is designed using information of the magnetization current and a proportional integral control action of the error. The stability of the periodic orbit is proven via the monodromy matrix, and the robustness, after the first tests of the ...

A Single-stage Boost-Flyback PFC Converter

2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006
This paper presents a novel single-stage single-switch power factor correction (PFC) converter. The proposed topology is derived by combining a boost cell and a flyback cell into one power stage. In this converter, the transformer in the flyback cell has two-coupling primary windings, which have the same turns.

Boost‐flyback converter: Experimental assessment of recent control techniques

International Journal of Circuit Theory and Applications, 2023
AbstractThe boost‐flyback converter is a type of DC‐DC power converter that allows for efficient step‐up voltage conversion. Despite its potential for achieving high voltage gains, there is a lack of comprehensive analysis and practical implementation of reliable control methods for this converter.

A Hybrid Boost–Flyback/Flyback Microinverter for Photovoltaic Applications

IEEE Transactions on Industrial Electronics, 2020
For photovoltaic applications, the flyback microinverter with pseudo-dc-link is popular as a simple topology but brings large transformer turns ratio and thus large leakage inductance, which would deteriorate the converter efficiency. To solve this issue, based on the nonisolated pseudo-dc-link structure, this paper proposed a hybrid boost–flyback ...
