This paper focuses on grid connected PV inverter incorporating the improvement of power quality issues in its controller design. Proportional resonant (PR) controller is used for eliminating steady state error and for the fast dynamic response. A repetitive controller is used for tracking periodic reference signals and to compensate harmonic disturbances. To attain low THD and quick steady state process, feed forward approach is implemented in controller design. The stability of the voltage and current controller is examined in bode plot. Phase locked loop (PLL) synchronization technique with LCL filter is also examined. A single phase Grid connected 3Kw PV inverter is modeled and simulated in MATLAB/Simulink/PLECS environment with the accurate results in its waveform. © 2015 IEEE.
