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 (
