Modeling and control of a dc-dc resonant converter interfacing fuel cell in electric vehicle

An electric vehicle powered by the fuel cells called fuel cell electric vehicles has higher efficiency and lower emissions compared with the internal combustion engine vehicles. In this paper presents modeling and control of a dc-dc resonant converter interfacing fuel cell for electric vehicle. The necessary energy to move the vehicle is provided by two separate energy sources, which are fuel cell and a super capacitor. A high frequency DC-DC converter fed by fuel cell is analyzed. The mathematical model of the fuel cell is presented and the average model and the controller of the dc-dc converter is elaborated. The proposed converter is digitally simulated using the MATLAB/ Simulink/ Sim Power Systems software. The dynamic performances of the electric vehicle drives are examined for the standardized European speed cycle type.
