DOI: 10.1109/tie.2021.3095813
Abstract: Suppressing the negative effects of grid voltage harmonics on the estimated frequency of a phase-locked loop (PLL) is a challenge in literature. This article proposes an easy-to-implement quadrature signal generator (QSG) to attenuate the oscillations… read more here.
