Abstract: This paper presents an approach to synthesizing the power electronics conversion topologies for the fuel cell UPS. Various topology structures are obtained. One structure is selected for further study. Since the inverter is critical to the utilization of the expensive fuel cell, the inverter efficiency is investigated with loss breakdown and the experiment. With regards to the energy management for fuel cell, ultra-capacitor is introduced. The connecting of the Ultra-capacitor to FC-UPS is studied and connecting approaches are compared.
