A high-efficiency high step-up current-fed multiresonant converter (CFMRC) is proposed for interfacing the sustainable power sources, such as PV panels and fuel cells, which are characterized by low-voltage high-current output and have strict current ripple requirement. The proposed converter has the features of low input current ripple, low circulating energy, achieving zero-current switching (ZCS)...
A high step-up current fed multi-resonant converter (CFMRC) has been proposed recently for renewable energy harvesting where the sustainable power sources such as PV panels and fuel cells are characterized by low-voltage, high-current output. An output voltage doubler is applied to the previously proposed CFMRC for the purpose of reducing the turns-ratio of the transformer. Compared to the CFMRC with...
A previously proposed current fed multi-resonant converter (CFMRC) has the merits of low input current ripple, high step-up capability and high efficiency. However, in order to ensure zero-current switching (ZCS) of its secondary rectifying diodes, the switching frequency range is limited hence the voltage regulation range is limited. In this paper, the switching frequency range is broadened for the...
