N2 - Synchronization control is of great importance for grid-connected power converters, therefore precise phase angle information of the grid voltage is essential. SRF-PLL aims to track the fundamental frequency positive sequence with zero steady state error. The moving average filter (MAF) is used to eliminate the disturbances of phase error, which is set in-loop of PLL in dq rotate frame. Due to additional time constant induced by MAF, the transient response of the MAF-SRF-PLL is slow. In this paper, a digital effective lead comb compensator cascaded with MAF is proposed to improve the dynamic response. The simulation by using Matlab/Simulink is made to verify the validity and effectiveness. Experiments results are also presented and the comparison with conventional MAF-SRF-PLL verified that the dynamic performance can be significantly improved.
