A double inductor current source DC/DC converter for 2kW fuel cell application

In order to use hydrogen fuel cells in domestic applications either as main power supply or backup source, their low DC output voltage has to be matched to the level and frequency of the utility grid AC voltage. Such power converter systems usually consist of a DC-DC converter and a DC-AC inverter. In this paper a double inductor step-up push-pull converter is investigated, presenting simulation and experimental results of the system. The converter is elaborated for 2kW power to match the rated power of the proton exchange membrane (PEM) fuel cell located in hydrogen fuel cell research laboratory of Riga Technical University.
