Design and dynamic modeling of a fuel cell/ultra capacitor hybrid power system

摘要

The aim of this paper is firstly to describe the design than to introduce a new approach of dynamic modeling and simulation results of a Fuel cell/Ultra capacitor (FC/ULC) hybrid power system. The developed model is represented in the state space, so it can be used to implement a suitable control strategy. The given design shows that the transient behavior, effect of the Fuel Cell, is eliminated by the use of the Ultra capacitor through the Flyback converter (FIBC). Thus, the output voltage from the source is maintained with a certain range and meets power demand of the load at high efficiency.
