Abstract

A high step up converter having rippleless input current is proposed for a fuel-cell power conditioning system. The proposed converter consists of a double current-fed half-bridge circuit at the primary side and a bridgeless rectifier with series-resonant circuit at the secondary side. Interleaving scheme and fixed 0.5 duty-cycle operation at the primary-side make the input current ripple become zero. A high step-up capability of the proposed converter can be achieved by secondary switching operation. The steady-state operation for the proposed converter is analyzed. A 600-W prototype converter was built and used to validate the performance of the proposed converter.
