Recent researchers and development work in the field of renewable energy sources (RES) have shown excellent progress and became an alternate solution of the conventional fuels. On the other hand, there is a social concern for environmental degradation as a green-house effect, climate change and global warming. Use of conventional fuel sources causes depletion in atmospheric layers and enhance carbon emission in the environment. The solution for such problems can be done by exploring an alternate solution to fulfil the fuel demand through renewable energy sources. The renewable energy sources mainly count fuel cell, photovoltaic, biogas/biomass and wind energy. A fuel cell is an electrochemical energy conversion static device. It is the best alternate solution to fulfil conventional energy demand, where, it uses hydrogen as its fuel and produce water and heat as a byproduct. In modern times, Fuel cell vehicle is the fastest growing market in comparison to vehicles having ICE (Internal combustion engine). This thesis introduces a novel propulsion system architecture of a fuel cell-based vehicle. Efficient Power conversion technologies are strategic to the advancement of fuel cell vehicles. The fuel cell is used to provide power input to proposed system topology, where, an energy storing device (battery) is used to provide fast acceleration to the vehicle and to store energy recovered during regenerative braking. Interleaved isolated bidirectional dc-dc converter topology is proposed in the system to minimize the stress over the system and to gain a high magnitude of stiff dc voltage. An h-bridge inverter is utilized to convert this stiff dc voltage to a balanced three-phase AC waveform to run heavy vehicle using three-phase induction motor drive. A single section LC filter is also designed to get the filtered AC output, with suppressed harmonics in the output.
