An Adaptive Frequency Phase-Locked Loop Based on a Third Order Generalized Integral

An Adaptive Frequency Phase-Locked Loop Based on a Third Order Generalized Integral

In this paper, the basic principle and characteristics of a phase-locked loop (PLL) in a single phase grid-connected system are analyzed, and this paper introduces one type virtual orthogonal voltage vector method based on a third order generalized integrator (TOGI) to construct an alpha and beta st...
