Title: Single-phase filter for reducing harmonics

Abstract: A harmonic current filter includes a first and second power system connectors and first and second load connectors, wherein the second power system connector is directly connected to the second load connector. The filter has a magnetically permeable core with three legs. A first line winding is connected between the first power system connector and the first load connector and is wound around one leg in a manner to produce magnetic flux having a given polarity. A capacitor and a first shunt winding are connected in series between the first power system connector and the second load connector. The first shunt winding is wound around another leg in a manner to produce magnetic flux having an opposite polarity.
