| Abstract |
Fuel cells deliver dc current which demands a dc/ac converter between the fuel cell and the mains to feed in electrical energy. An inverter of the current source type makes it possible to convert the energy supplied by a fuel cell into the mains without using an auxiliary dc/dc-converter. The current
source inverter’s efficiency depends on the input dc voltage of the inverter, so the rating of the fuel cell voltage influences the
overall efficiency of the system.
After a short introduction of the fuel cell’s electrical behaviour, the current source inverter and the impact of its LCFilter on the inverter’s input voltage are described. The dimensioning process dependent on the power range of the fuel cell and the current source inverter is shown. In doing so, the characteristics of the fuel cell and the inverter are taken into
account. A laboratory setup of a current source inverter has been built and a control scheme is presented. Simulation results of the
general system behaviour are shown. |
