An Effective Solution to Eliminate DC-Offset for Extracting the Phase and Frequency of Grid Voltage
Recently, several approaches with the ability to reject the DC-offset in phase locked loop (PLL) methods have been developed. These approaches include different filtering structures which can be classified into two categories: prefiltering before the PLL input and in-loop filtering in the PLL contro...
