Multiple inductive component
First Claim
1. A device, comprising:
- a cylindrical drum core component with a cylindrical outer surface and at least two axially spaced circumferential grooves in the cylindrical outer surface, the cylindrical drum core component comprising a separation disc portion between the at least two axially spaced circumferential grooves and two outer disc portions at the sides of the at least two axially spaced circumferential grooves, respectively, directed away from the separation disc portion;
a first winding arranged in a first axially spaced circumferential groove;
second winding arranged in a second axially space circumferential groove;
a cylindrical shell core component arranged coaxially around the cylindrical drum core component;
an annular core component disposed between the cylindrical shell core component and the separation disc portion of the cylindrical drum core component; and
two outer air gaps between the cylindrical shell core component and the two outer disc portions, respectively,wherein the separation disc portion is (i) magnetically short circuited with the cylindrical shell core component, or (ii) separated from the cylindrical shell core component by a central air gap narrower than a narrowest air gap of the two outer air gaps such that the first winding and the second winding are magnetically separated.

Abstract
A multiple inductive component (100) comprises:—a cylindrical drum core component (120) with at least two axially spaced circumferential grooves (131, 132) in its cylindrical outer surface (121), a separation disc portion (111) between said two circumferential grooves and two outer disc portions (112, 113) at the sides of the said two circumferential grooves, respectively, directed away from the separation disc portion;—at least one first winding (141) arranged in a first one (131) of said grooves;—at least one second winding (142) arranged in a second one (132) of said grooves;—a cylindrical shell core component (150) arranged coaxially around the cylindrical drum core component;—two outer air gaps (162, 163) between the cylindrical shell core component and said two outer disc portions, respectively. The separation disc portion is magnetically short circuited with the cylindrical shell core component.
