Multiresonant Frequency-Locked Loop for Grid Synchronization of Power Converters Under Distorted Grid Conditions [PDF]

IEEE Transactions on Industrial Electronics, 2011
This paper presents a new multiresonant frequencyadaptive synchronization method for grid-connected power converters that allows estimating not only the positive- and negative-sequence components of the power signal at the fundamental frequency but ...

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 Fixed-Length Transfer Delay Based Adaptive Frequency-Locked Loop for Single-Phase Systems [PDF]

IEEE Transactions on Power Electronics, 2019
This letter presents an adaptive frequency-locked loop (FLL) with fixed-length transfer delay units for single-phase systems. By analyzing the relationship between the grid voltage and its transfer delay signals, a linear regression model of the grid ...
