DC/DC converters for fuel cell powered hybrid electric vehicle

Many automotive companies are working in developing fuel cell powered hybrid electric vehicles (HEV) because they offer a reduced emission and improves the fuel economy. The key technology for such development of fuel cell for propulsion is the power electronics. This paper reports different DC/DC converter topologies used to interface the fuel cell to the motor controllers in HEVs. The aim is to present a simple and practical boost converter topology with a coordinated control that can regulate both the output voltage and the input current simultaneously. The performance of the proposed power conditioning system is evaluated in simulation results under different dynamics.
