This Paper proposes a Hilbert transform weight factor (HTWF) based control strategy for improving the reliability of grid integrated solar photovoltaic (PV) system. The integration of PV to the main grid increasing numerously across the globe. However, grid synchronization, stability and harmonic elimination is always a challenge under distorted grid voltage conditions. The proposed HTWF control strategy uses delayed input vectors to extract fundamental supply voltage components from the distorted supply voltage. Further, a complex filter is being inserted to synchronize the PV system with the utility grid without any phase delay. The proposed HTWF based DC-link voltage control technique is developed in a MATLAB®/ Simulink environment. The performance of the proposed HTWF based DC-link voltage control technique is tested in comparison with LMS and LAD based control techniques under various grid supply and load currents. The MATLAB simulation results show that the proposed system is robust, takes lesser time for convergence, no synchronizing problems along with maintain the harmonic spectral of source current within IEEE-519 standards.
