Abstract<br />
This research presents a new method based on predictive current control (PCC) <strong>of</strong><br />
fuel cell based distributed generation systems (DGS) in a standalone AC power supply. To<br />
boost low output DC voltage <strong>of</strong> the fuel cell to high DC voltage and compensate for its<br />
slow response during the transient, two full-bridge DC to DC converters are adopted and<br />
their controllers are designed based on PCC. The proposed method produces the reference<br />
current by using <strong>of</strong> the DC link capacitor voltage. Thereupon the method determines the<br />
portion <strong>of</strong> fuel cell and backup battery to feed load and capacitor. The analysis results<br />
presented in this research demonstrate that the suggested method is capable to increase<br />
transient performance <strong>of</strong> adopted system in load and fuel cell output voltage variations.<br />
Simulations with MATLAB have been carried out to verify the proposed predictive current<br />
controller in mentioned application and the results are discussed in this research.<br />
