{"title":"Comparison of the DC\/DC-Converters for Fuel Cell Applications ","authors":"Oleksandr Krykunov","volume":3,"journal":"International Journal of Energy and Power Engineering","pagesStart":520,"pagesEnd":529,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/11554","abstract":"The source voltage of high-power fuel cell shows strong load dependence at comparatively low voltage levels. In order to provide the voltage of 750V on the DC-link for feeding electrical energy into the mains via a three phase inverter a step-up converter with a large step-up ratio is required. The output voltage of this DC\/DC-converter must be stabile during variations of the load current and the voltage of the fuel cell. This paper presents the methods and results of the calculation of the efficiency and the expense for the realization for the circuits of the DC\/DC-converter that meet these requirements.
