This paper deals with the modeling and simulation of suitable DC-DC converters for Fuel cell system. In the field of renewable energies, power electronics and fuel cell technologies play an important role. As the fuel cells become the main power source for portable applications, demand for fuel cells will increase. A highly efficient converter is an essential requirement in this application and a core parameter of the device as a whole. Therefore, a high efficient converter has to be designed for fuel cell system as the output voltage of fuel cell is low. In this paper, various DC-DC converters such as Boost converter, SEPIC, LUO converter and ZETA converter with fuel cell as an input source are designed and the same is simulated using MATLAB. Total Harmonic Distortion analysis of all the DC-DC converters is carried out and the suitable converter for fuel cell application is selected based on the low Total Harmonic Distortion value.
