Fuel Cell Generation System Combined Interleaved Full-bridge Converter with Half-bridge Inverter

인터리브드 풀브릿지 컨버터와 하프브릿지 인버터를 결합한 연료전지 발전 시스템

This paper suggested a fuel cell generation system which combined interleaved full-bridge converter with half-bridge inverter. High ratio step-up converter is essential to use the power as general voltage source. Full-bridge converter has high efficiency and can boost the input voltage to high output with transformer. With series connected capacitors, interleaved full-bridge converter and half-bridge inverter are combined. Half-bridge inverter has two fewer switches compared to full-bridge type. Also, switching loss can be reduced. The performance is verified through simulation with 1.5[kW] fuel cell generation system.
