All-Pass-Filter-Based PLL for Single-Phase Grid-Connected Converters Under Distorted Grid Conditions

All-Pass-Filter-Based PLL for Single-Phase Grid-Connected Converters Under Distorted Grid Conditions

All-pass-filter-based single-phase phase-locked loop (APF-PLL) is a widely used grid synchronization method in grid-connected power converters. However, the performance of APF-PLL degrades under distorted grid conditions and the estimated phase and frequency will contain low-frequency oscillation te...
