High-Efficiency Boost-Flyback Converter with Voltage Multiplier Cells for High Voltage Gain Application

António Manuel Santos Spencer Andrade, Everson Mattos, Mário Lúcio da Silva Martins

Abstract

In this paper, a Boost-Flyback converter is presented. It combines the voltage multiplier cells to the secondary winding of the coupled inductor in the Flyback part of the converter and a switched capacitor to the output capacitor of the Boost part of the converter. This converter shows attractive characteristics such as high voltage gain, low voltage stresses on semiconductor and a high efficiency at 97.4%. A detailed description of the proposed converter is presented and experimental results.
