Abstract :
The fuel cell and the accumulator and/or super-capacitor are connected to the same voltage bus through an appropriate multiport DC/DC converter, in fuel cell electric vehicle. The accumulator and/or the super-capacitor are auxiliary energy source, which provides or absorbs the dynamic power when the load varies and the main power supply cannot respond immediately, so the system dynamic characteristics are improved. A multiple port dc-dc converter (MPDC) devoted to combine the power flowing from combined on-board energy sources is presented; Eventually, the analysis and design validation are verified via the simulation and experiment.
