Abstract

In this paper, the two-stage DC-DC converter is proposed to make the control simple and to boost the low input voltage in the fuel cell generating system. The low efficiency of the conventional power converter is caused by a characteristic of the low-voltage and high-current in the fuel cell generating system. High-frequency transformer is needed to block the noise and to guarantee the safety of cell and load as a magnetically insulation. The proposed two-stage DC-DC converter for a fuel cell generation is more efficient than the traditional one-stage converter and easy to control. The design of a high-frequency transformer is also simple. Finally, the utility of the proposed converter is proved by the simulations and experiments.
