– Harmonic distortion, zero sequence harmonic currents, electromagnetic filter.


– This paper aims at presenting the operation principle, modelling, computational implementation and performance studies of an electromagnetic zero sequence harmonic filter. This proposal considers a combined shunt and series filter units so as to reach a better overall performance. Besides theoretical and computational concepts, a prototype experimental performance is also included into the studies.
