A High Boost DC-DC Converter with Less Input Current Ripple: Derivation, Analysis and Implementation

A non-isolated high-boost DC-DC converter is proposed for connecting fuel cell to DC bus. The proposed converter has a remarkable voltage gain at low duty-cycle. Moreover, the less input current ripple and shared input/output ground characteristics also make it more advantageous. Next, the derivatio...

Description
Summary:A non-isolated high-boost DC-DC converter is proposed for connecting fuel cell to DC bus. The proposed converter has a remarkable voltage gain at low duty-cycle. Moreover, the less input current ripple and shared input/output ground characteristics also make it more advantageous. Next, the derivation process and characteristics analysis of this converter were described thoroughly. At last, a 400W prototype was built, which demonstrates the superior performance of this converter and the reliability of theoretical analysis.
