Study on Adaptive Harmonic Extraction Approaches in Active Power Filter Applications [PDF]

open access: yes, 2014
Active power filter (APF) has now become a mature technology for harmonic and reactive power compensations in two-wire (single phase), three-wire (three phase without neutral), and four-wire (three phase with neutral) ac power networks with nonlinear ...
