High Step-Up Converter With Three-Winding Coupled Inductor for Fuel Cell Energy Source Applications

High Step-Up Converter With Three-Winding Coupled Inductor for Fuel Cell Energy Source Applications Abstract: This paper presents a high step-up converter for fuel cell energy source applications. The proposed high step-up dc-dc converter is devised for boosting the voltage generated from fuel cell to be a 400-V dc-bus voltage. Through the three-winding coupled inductor and […]


A High Efficiency Flyback Micro-inverter With a New Adaptive Snubber for Photovoltaic Applications

A High-Efficiency Flyback Micro-inverter With a New Adaptive Snubber for Photovoltaic Applications Abstract: Based on the hybrid operation of interleaved flyback micro-inverter in discontinuous and boundary conduction modes (DCM and BCM), a novel adaptive snubber is proposed in this paper. The proposed snubber limits the drain-to-source voltage overshoot of the flyback’s main switch during the […]
