In this study, implementation of a 10kW three-phase grid-connected inverter system is discussed. The system includes a high voltage dc-link, a two-level inverter and filter inductances. The high voltage dc-link is obtained from AC grid by means of a transformer, a diode rectifier and filter capacitors. The two-level inverter is controlled with SVPWM technique, and L filter is used between the inverter and the AC grid. The system is simulated in MATLAB/Simulink and, appropriate dc-link voltage, filter inductance and switching frequency values are selected. The experimental results are presented from the laboratory prototype which is controlled by dSPACE DS1103 board to demonstrate the power control and harmonic performance. It is observed that at 9 kHz switching frequency, 650V dc-link voltage and 10 kW output power, the total harmonic distortion of the grid current is less than 3.4%, and power factor is higher than 0.99.
