Abstract

The paper deals with the power converter to be used in realising small scale UPS based on fuel cell. Different structures of standard UPS are analysed and modified to consider the presence of fuel cell as DC current energy source. The control of the DC/AC converter interfacing the fuel cell based UPS with the AC grid is based on feed-forward action able to minimize the time delay in reconstructing the AC voltage at the load bus whichever UPS structure is used. The realised 1.2 kW prototype is also shown demonstrating the actual possibility of realizing the proposed system using commercial converters
