Several advance control solutions have been recently introduced to cope with this problem and introduce a control scheme that improves the harmonic distortion in such adverse conditions. A simple control scheme is proposed here as a good alternative of previous control solutions for voltage source single-phase PV inverters connected to the utility grid. In this paper Phase, the Shift modulation technique is carried out, in order to obtained low current distortion even during polluted grid conditions. To achieve the reliability of the system, good quality of power must be transmitted to the grid with less harmonic and unbalance. Hence proper filter action is to be carried out to attenuate ripple. Thus the main contribution of this work is the Phase Shift PWM control scheme intended for single-phase applications which features high harmonic rejection capability and obtained improved THD.
