Abstract (en)
An inductor comprising a magnetic core (2) forming a closed loop path for a magnetic flux, the magnetic core (2) having a high permeance element (4) interrupted by a low-permeance gap (6), the low-permeance gap (6) having an inner portion (61) and an outer portion (62), a distance between a centre (41) of the magnetic core (2) and the outer portion (62) being greater than a distance between the centre (41) of the magnetic core (2) and the inner portion (61), and a conductor (8) coiled around the magnetic core (2). The inner portion (61) of the low-permeance gap (6) has a substantially greater dimension in a circumferential direction than the outer portion (62) of the low-permeance gap (6).
