Induction component

Abstract

The invention proposes an induction component produced using thin film technology which can be used for a variety of functions. It contains, on a magnet core with a ring shape, two coil devices which, for their Part, are in turn constructed from at least two coils. The adjacent end windings of adjacent coils are connected to one another and to a common solder pad within each coil device. This makes it possible to connect individual coils and thus to utilize different functions of the induction component.

Description

(1) Further features, details and preferences of the invention result from the claims and the abstract, with the wording of said claims and abstract hereby being incorporated by a reference in the content of the description, and from the following description of preferred embodiments of the invention as well as with reference to the drawing, in which:

(2) FIG. 1 shows, schematically, the illustration of a possible induction component in accordance with the invention.

(3) FIG. 1 shows the plan view of the induction component. In the embodiment illustrated, it contains a magnet core 1. This has the shape of a rectangular ring, with two limbs 2 running in the longitudinal direction and two transverse limbs 3 connecting said limbs. A plurality of coils 4 are arranged around each longitudinal limb 2, wherein all of the coils 4, 5 of a longitudinal limb 2 form a coil device 6. The expression that the coils 4, 5 are wound is only to be understood in terms of function since the coils are produced using the thin film method, i.e. are not wound. This method for producing coils. is known per se.

(4) Each coil 4 has a winding start 7 and an end winding 8. All of the coils 4 are wound in the same direction, i.e. have the same winding sense. All of the coils 4 have the same number of turns. The coils 4 are arranged one behind the other in the longitudinal direction of the limb 2 and have a certain distance from one another. The winding start 7 of the coil 4 illustrated furthest on the left is passed out and connected to a solder pad 9. The end winding 8 of this coil is likewise passed out and connected to a solder pad 9. The winding start 7 of the second coil is also connected to this solder pad 9. The end winding 8 of said second coil is in turn connected to a solder pad 9, to which the winding start 7 of the third coil is also connected.

(5) Everything that has been mentioned for the coils 4 of the first coil device 6 also applies to the second coil device illustrated below in FIG. 1. In particular, the turns numbers and the winding sense of the coils can also be the Same as one another.

(6) The induction component shown in FIG. 1 has in total 8 connections. By virtue of the subdivision. into two coil devices, which are not electrically connected to one another, the induction component can be used as a transformer. The following transformation ratios are possible 1:1, 1:2, 1:3, 2:1, 2:2, 2:3, 3:1, 3:2, 3:3.

(7) However, it is also possible to use the induction component as an inductance, wherein a single coil 4 or else a series connection of a plurality of coils both 4 and 5 can be used. Therefore, an inductance with the inductance value of a coil up to the inductance value of 6 coils can be implemented.
