The purpose of the green power inverter is to converter the dc-power delivered from the fuel cell to ac power into the grid. The fuel cell voltage is relative low (18-55 V) compared to the 230 Vrms ac line voltage and the voltage gain is therefore relative high. Hence, the green power inverter must invert the dc-power to ac-power and magnify the voltage level. Two types of converter systems will be analysed: Single step topologies consisting of only a single power electronic converter and two step topologies which consist of and dc-dc converter in series with an inverter. A circuit topology is selected and a prototype is realized and tested up against a fuel cell and the grid " Christian Klumpner, Gert K. Andersen, Frede Blaabjerg, Søren B. Kjær.
