Abstract :
Several converter configurations have been proposed in literature to achieve fuel-cell power conversion systems. In this paper a new converter high frequency unidirectional DC-DC was proposed simulated and realized. This last one allows to obtain an output voltage is 550V from an input voltage of 28V (output voltage of fuel-cell). The control strategy used is the shift phase of the full bridge converter. In this case, we minimize the switching losses. We replaced the converter at two levels of voltage by only one full bridge converter using two planar transformers in high frequency (the primary are coupled in parallel and the secondary are in series). Indeed, we minimized the size and the weight of the converter. Simulation results are carried out with Matbab/Simulink Software. Finally the experimental results are given and compared to the simulation ones.
