Simulation and Hardware and Implementation of Directly Coupled Four Phase Interleaved Boost Converter for Fuel Cells

Abstract:

Fuel cell is one of the promising renewable and sustainable power sources because of its high power density and very low emission. In order to design a highly efficient fuel cell power system, a suitable DC-DC converter is required. In this paper, a four-phase directly coupled Interleaved Boost Converter (IBC) for fuel cell is proposed. A four-phase structure with interleaved control is proposed to reduce the input current ripples, the output voltage ripples, and the size of passive components with high efficiency compared with the other topologies. Mathematical analysis of overall current ripple, design of inductance and other components is investigated. Simulation study of the proposed converter interfaced with fuel cells is carried out using MATLAB. A prototype is built using MOSFET to validate the simulation results.
