단일 변압기를 사용한 SEPIC-Flyback 컨버터의 연료전지 발전 시스템

A Fuel Cell Generation System of SEPIC-Flyback Converter using a Single Transformer

In this paper, a new SEPIC-Flyback converter with a single transformer has been proposed, which is suitable for a fuel cell based power generation system. The proposed converter is superposition of sepic and flyback converter mode. It has outstanding high boosting output voltage, component utilization and high efficiency characteristics under the inherently severe low output voltage of the fuel cell generator. The proposed converter for a full cell generator is described and verified by simulation and experimental result that make used of the Polymer Electrolyte Membrane Fuel Cell(PEMFC) Generator.
