Abstract: At present, the electric vehicles (EVs) have a dominant role for visualising the pollution less environment. Moreover, it is important to design efficient power conditioning units for fulfilling the desired tasks. With advancements in the technology, the fuel cells (FCs) can provide a better solution for powering the EVs. However, their downside is the production of very low output voltage. Therefore, this necessitates a high step ratio DC-DC converter for providing the desired dc link voltage for DC-AC converter. This paper focuses on fuzzy logic control (FLC) based high gain DC-DC converter for EV applications. The fuzzy controllers are superior in dealing the nonlinearities and plant parameter variations without the need of strict mathematical modelling of the converter system. The converter is simulated with simple voltage mode control as well as FLC based voltage mode control. The MATLAB simulation results are compared for the above two control strategies with an emphasis on the steady state and dynamic regulations.
