Fuzzy Logic Implementation of Pem Fuel Cell Based Four Phase Interleaved Boost Converter

M. Tamilarasi and R. Seyezhai

This paper implements the fuzzy logic control technique for the modeling of the PEM (Proton Exchange Membrane) fuel cell interfaced with a four-phase coupled IBC (Interleaved Boost Converter). In the modeling part of the PEM fuel cell, a fuzzy logic controller (FLC) is used to control, the flow rate of methane in the reformer and then output voltage of IBC is maintained constant by incorporating a FLC. The modeling, control and simulation is achieved for PEM fuel cell interfaced with four-phase coupled IBC. MATLAB simulink and fuzzy logic toolbox are used to check the proposed control algorithms.
