The first six components in the load current are determined using the information contained in the time-varying waveforms. The effectiveness of this method is verified by using it in a single-phase active power filter with selective compensation of the current drained by an AC controller. The proposed method is compared with the fast Fourier transform.65-73porHarmonicspower systemartificial neural networksArtigo10.1109/TLA.2010.5453948WOS:000277053200010Acesso abertoWOS000277053200010.pdf48317899018238490000-0002-9984-9949
