Application of High Voltage Ratio and Low Ripple Interleaved DC-DC Converter for a Fuel Cell
Authors: , ,
Abstract: This paper proposes a high voltage ratio and low ripple interleaved boost DC-DC converter, which can be used to reduce the output voltage ripple. This converter transfers the low DC voltage of fuel cell to high DC voltage in DC link. The structure of the converter is parallel with two voltage-doublers boost converters by interleaving their output voltages to reduce the voltage ripple ratio. Besides, it can lower the current stress for the switches and inductors in the system. Finally, some experimental results are made to verify the feasibility of the proposed converter.
