Dynamic model of an FC- and UC-based IPT system for railway vehicle

A fuel cell powered system is regarded as a high current and low voltage source. Effects of electric loads on the power source are of importance to design an optimal integrated system. In particular, dynamics of the system should be considered to determine a configuration and the size of the components. In this paper, we present an IPT system that operates in parallel with FC and UC bank, because the available power generated from a FC power plant may not be sufficient to meet sustained load demands, especially during peak demand or transient events encountered in railway vehicle applications. A new dynamic model and design methodology for an FC- and UC-based IPT system for railway vehicle applications has been developed. Simulation results are presented using MATLAB, Simulink, and Ansoft EM environments based on the mathematical and dynamic electrical/magnetical models developed for the proposed system.
