Control of PV-grid connected inverter introduces a delay between sinusoidal current reference and measured current at the output of the inverter. This leads to a phase difference between the current injected by the inverter and grid voltage when using a simple PI controller. To overcome this problem, PI controllers used to control injected currents to the grid have been substituted, in this study, by resonant controllers. The obtained results show that phase difference between grid current and voltage have been practically suppressed; hence power factor obtained is close to one.
