چکیده
In this paper a high frequency DC-DC converter fed by fuel cell is analyzed. The converter consists of full bridge inverter connected to full bridge rectifier through two planar transformers and parallel resonant. The mathematical model of the fuel cell is first presented and the average model of the converter is elaborated. The developed model is used to study the characteristics and dynamics of the DC-DC converter in closed loop. Validation of the proposed model is verified through simulation.
