Design and practical study of three phase interleaved boost converter for fuel cell electric vehicle

Even being far from spared by the new challenges, the automotive sector is at the heart of changes as it produces of greenhouse gas emissions and it is responsible for air pollution and global warming. So, moving towards electricity productions based on green/clean energy has become increasingly important. The fuel cell (FC) produces electrical energy from hydrogen and oxygen without the release of pollutants. Its use in the automotive sector is therefore considered in the long term to address the problem of sustainable mobility. However, some matters are persisting due to the feeble voltage generated at the fuel cell outflow. Eventually, a DC/DC converter turns to be necessary to enhance this voltage to the appropriate standard of the DC bus voltage. In order to fulfill all requirements for electrical vehicle applications using fuel cell as main energy, the interleaved boost DC/DC and isolated DC/DC converters were adopted to provide better performance. This research work focuses on the analysis and design approach for the new topology of DC/DC power converter that interface a fuel cell used an electric vehicle. The proposed interleaved boost converter is validated experimentally by the obtained results from a prototype that has been built and tested in our laboratory based on DSP1104 and FPGA. The interleaved converter which ensures the minimization of the output current ripples of the fuel cell and guarantee the reliability of the system.
