Review of harmonic current extraction techniques for an active power filter

Massoud, A. and Finney, S.J. and Williams, B.W. (2004) Review of harmonic current extraction techniques for an active power filter. In: Harmonics and Quality of Power 2004. IEEE, New York, pp. 154-159. ISBN 0780387465

Since the early 80s, many harmonic extraction techniques have been published in the literature but there is a lack of publications which review harmonic current extraction techniques for researchers and engineers in the field of active filters. In this paper, classification of harmonic extraction techniques (time-based and frequency-based) is presented, giving a brief explanation of the techniques classified under each category and their reference source.
