Abstract: Dual quadrature signal generator (QSG) along with a positive sequence calculator (PSC) eliminates the negative sequence components from unbalanced grid voltages. The QSGs also offer attenuation to harmonics and dc-offset present in the sensed input… read more here.

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.
