Interest of renewable energy sources increases with the increasing world power demand and decreasing of fossil energy sources. Many of the new energy sources like the PV, the fuel cell or the wind, produces direct voltage so it is needed a suitable direct current to alternating current inverter to connect them to an alternating current load or the utility line. In this case utility interactive inverters became more important. In this study, a dSPACE based current controlled utility interactive inverter has been designed and implemented. PI current controller was used for the production of switching pattern and the output of the inverter was filtered by an LCL type filter. A graphical user interface has been designed to monitor the analog and the digital variables. Results of both MATLAB/Simulink simulation and experimental studies show that inverter output current is in phase with line voltage and current harmonies in the limits of international standards (<5%).
