Real Time Simulation of Proton Exchange Membrane Fuel Cell Hybrid Vehicle

This paper will present results on the real time and rapid simulation of a Proton Exchange Membrane (PEM) based fuel cell hybrid electric vehicle. The fuel cell hybrid vehicle (FCHV) is composed of a battery, a fuel cell, a DC-DC converter and a PMSM motor drive. The converters in the circuit are modeled with special interpolating IGBT bridge models (RT-Drive Time Stamped Bridges) that are very accurate despites the 10 kHz carrier frequency and the 10 microseconds sample time of simulation. The detailed Emmeskay PEM fuel cell stack model is used for the simulation. In the paper, the RT-LAB system is demonstrated to accelerate simulation by a factor greater than 1000 and help decrease the development cycle time of FCHV.
