A new LPF-based grid frequency estimation for the SOGI filter with improved harmonic rejection

open access: yes
This paper proposes a new method for the estimation of the grid voltage frequency using a low-pass filter (LPF) approach. The estimated frequency is used to tune a second order generalized integrator (SOGI) filter commonly used for grid monitoring ...

Impedance Analysis of SOGI-FLL-Based Grid Synchronization

open access: yesIEEE 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. Alternatively, this letter presents the impedance analysis of the second-order generalized integrator frequency-locked loop (

A Speed Estimation Scheme Based on An Improved SOGI-FLL for Speed-Sensorless Control of Induction Motor Drives

open access: yesIECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
With the aim to enhance the system reliability and reduce the system cost of induction motor drives, the speed-sensorless control, implemented by various speed estimation schemes, is demanded. The speed estimation provided by the second-order generalized integrator-frequency-locked loop (SOGI-FLL) is emerging as a promising method for speed-sensorless ...

Improving performance of single-phase SOGI-FLL under DC-offset voltage condition

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
The second-order-generalized-integrator frequency-locked loop (SOGI-FLL) is typically employed to synchronize with the grid in the single-phase grid-connected converter. The SOGI creates two orthogonal signals from an input grid voltage, and estimates the magnitude while the frequency locked-loop identifies the grid frequency.
