Abstract

The correct current or voltage phase angle of a power electronics equipment is an essential information, especially in those connected to grid as: thyristor rectifiers, active power filters and distributed generation systems. For this reason, up to this day there are several Phase-Locked Loop (PLL) algorithms presented. However, those algorithms usually suffer from unsatisfactory dynamic response when phase angle jumps or harmonic distortion are presented. In this paper, 2 (two) single-phase PLL strategies will be discussed and compared to a novel PLL based on Fuzzy Logic theory. From this, it will be possible to evaluate the dynamic behavior of each of the PLLs.
