This paper presents various applications of a nonlinear adaptive notch filter which operates based on the concept of an enhanced phase-locked loop (PLL). Applications of the filter for online signal analysis for power systems protection, control a

Article_herra Distorted voltage and current waveforms is one of the problems associated to electric power quality. Continuous use of non-linear loads provokes the existence of voltage waveforms with a high distortion. Thus, it is necessary to k

This paper presents a fuzzy logic algorithm to control DC-bus voltage of a shunt active power filter (APF). This work is done to illustrate the Performance and robustness of current Identification references by calculating the harmonics (THD) res
