Beschreibung
Zusammenfassung:	A differential and common mode filter for an inverter, comprising an inductor having a core. The core comprises: an upper yoke and a lower yoke which comprise a first magnetic material; a first leg, a second leg and a third leg which extend between the upper and lower yokes and around which a first coil, a second coil, and a third coil are arranged, respectively, wherein at least one portion of the first, second and third legs, when seen in a transverse cross section, is made of one second magnetic material, and wherein the first magnetic material has a magnetic permeability higher than the second magnetic material; at least one unwound leg extending between the upper and lower yokes.
