A Family of Gradient Descent Grid Frequency Estimators for the SOGI Filter
IEEE Transactions on Power Electronics, 2018 This paper applies the adaptive gradient descent method to the second-order generalized integrator (SOGI) filter in order to find an online estimation algorithm for the grid frequency, which leads to the proposal of three possible estimators. One of them is identical to the FLL algorithm reported in literature, which proves that it should be understood

Modeling and Analysis of SOGI-PLL/FLL-Based Synchronization Units: Stability Impacts of Different Frequency-Feedback Paths [PDF]
IEEE Transactions on Energy Conversion, 2021 Second-order Generalized Integrator (SOGI)-based quadrature-signal-generator (QSG), in conjunction with either a phase-locked-loop (PLL) or a frequency-locked-loop (FLL), is widely used as the synchronization unit of grid-tied converters. This paper will

A Frequency-Fixed SOGI-Based PLL for Single-Phase Grid-Connected Converters [PDF]
IEEE Transactions on Power Electronics, 2017 © 1986-2012 IEEE. Second-order generalized integrator (SOGI) based phase-locked loops (PLLs) are widely used for grid synchronization in single-phase grid-connected power converters. Previously, the estimated frequency of the PLL stage is fed back to the

Impedance Analysis of SOGI-FLL-Based Grid Synchronization
IEEE Transactions on Power Electronics, 2017 The latest research has pointed out that the Phase-Locked Loop (PLL) plays an important role in shaping the impedance of grid-connected converters, yet most of the works so far merely focus on the synchronous reference-frame PLL.
