- a soft magnetic segment for example, a ferrite segment may be provided. Furthermore, an amorphous, nanocrystalline or even bonded powder material can be used.
- the current capability can be increased by introducing suitable permanent magnets into a plurality of gaps.
- At least one insulator or an insulator segment is inserted into the stack of a plurality of soft magnetic segments.
- the insulator may be, for example, air or an insulating component, namely an insulator segment.
- insulator segment for example, a plastic segment, such as a plastic disc is suitable.
- a permanent magnet segment is arranged between all mutually spaced soft magnetic segments.
- the advantage of as many permanent magnet segments as possible is that, starting from a desired overall remanence of the arrangement, it is possible to use cost-effective magnets.
- the material of the permanent magnet segments may comprise a magnetic material made of a rare earth compound, in particular 5
- SmCo particular SmCo, NdFeB, SmFeN or a hard ferrite material, in particular SrFe, BaFe or a mixture of these materials.
- the soft magnetic segments and the permanent magnet segments and possibly the insulator segments have an identical outer contour and are stacked aligned with each other.
- a circular or angular outer contour of the stack can be provided.
- a cylindrical stack and, for example, a quadrangular outer contour would result in a square bar as a stack.
- the magnetic circuit of the inductor according to the invention may be designed as ETD circuit, E-circuit, OR circuit or as a shell core and have a single stack with wrapped coil.
- the individual constituents of such a preassembled, manageable unit are fixedly connected to one another, preferably glued, cast or encased by a suitable material.
- FIG. 1 shows a first exemplary embodiment of a throttle according to FIG. 1

- FIG. 1 shows a first embodiment of a throttle according to the present invention in side view and sectional view 8th
- the throttle is designated by the reference numeral 1 and has a magnetic circuit 10 which is formed as an ETD circuit.
- the magnetic circuit 10 has a lower, horizontally extending yoke 10a, at the left and right end of which connect vertically extending upward yokes 10b and 10c. These two yokes 10b, 10c are connected at their upper end via another, transverse yoke 10d. These yokes 10a, 10b, 10c and 10d are soft magnetic material.
- a stack 20 of a plurality of soft magnetic segments 22 is placed such that the stack 20 is connected at its upper and lower ends to the lower yoke 10a and the upper yoke 10d.
- an air gap, permanent magnet segment or an insulator segment can also be placed here.

- a permanent magnet segment 30 is placed in each case. 9
- the entire arrangement of the stack 20 shown in Figure 2 is aligned with each other and has, as Figure 3 shows, an annular outer contour. However, it is also conceivable to provide an angular contour here.
- the individual components of the stack 20, that is to say the soft-magnetic segments 22, the insulator segments 40 and the permanent-magnet segments 30, are fixedly mounted to one another, ie in particular glued together. After all, it is also easily possible for the entire stack 20 to be surrounded or enveloped by a suitable material.
- a suitable material for such encapsulation or enveloping for example, offers a resin material, polyamide, polyurethane, polypropylene, epoxy or silicone.
- This Umgie H or wrapping, for example, can be provided tubular, as it is indicated in Figure 2 by the dotted line and the reference numeral 60.
- a sleeve-shaped sheath 60 has the advantage that the upper side of the uppermost soft-magnetic segment 22 and the underside of the lowermost soft-magnetic segment remain free in order to be able to lie directly against the yokes 10a and 10d mentioned in connection with FIG.
- the envelope 60 is designed tubular in FIGS. 2 and 3 with the reference numeral 60.
- the material of the soft magnetic segments 22 may be, for example, ferrite, amorphous material, nanocrystalline material or bonded powder material or in the form of iron sheets.

- These coils 50 are wound around the stack 20 so that the permanent magnet segments 30 and also the air gap 40 are wound by the coil 50.
- FIG. 5 shows a third embodiment with a magnetic circuit 10 in E-shape.
- the magnetic circuit 10 consists of a bottom transverse yoke 10a from which two yokes 10b, 10c extend upwardly away. Between these two legs 10b, 10c lies the already known stack 20.
- FIG. 6 shows a magnetic circuit 10 in U-shape.
- FIG. 7 shows a magnetic circuit 10 in UR form with a yoke 10a, which is transverse and has a rectangular cross-sectional contour. From this yoke 10a extends left also with rectangular cross-section, a yoke 10b in one piece upward. At the right end of the yoke 10a sits the already known stack 20 with its soft magnetic segments 22 and the permanent magnet segments 30 and an air gap 40th
- FIG. 8 shows a throttle with a shell core, which has a circular yoke 10 with upper and lower lid and a centrally arranged stack 20 with permanent magnet segments 30 and soft magnetic segments 22.
- FIG. 9 shows two magnetic circuits 10 of virtually identical configuration, similar to FIG. 1, wherein only the stack 20 located in the middle varies with respect to its number of permanent magnet segments 30 used.
- the already known reference numerals stand for the same parts.
- only arrows are entered into the arrangements of the magnetic circuits 10 of FIG. 8 at the locations where permanent magnet segments 30 are inserted between the soft magnetic segments 22.
- the stack 20 has a total of eight soft-magnetic segments 22.
- a permanent-magnet segment 30 is located between all soft-magnetic segments 22.
- the entire stack 20 is wound by a coil 50.
- the stack 20 is likewise equipped with eight soft-magnetic segments 22.
- only between the fourth and fifth soft magnetic segment 22 is a single permanent magnet segment 30, which is significantly thicker than the seven permanent magnet segments 30 of FIG. 9 on the left.
- the entire stack 20 is in turn wrapped by a coil 50.
- Such cantilevered fields are responsible for ensuring that a large gap between two soft magnetic segments 22 is effective 13 has a larger cross-section. As a result, the magnetic resistance of the gap decreases, which is compensated by broadening the gap again.
- the throttle shown in Figure 9 right has a single gap into which a permanent magnet segment 30 is inserted with a thickness of 5.0 mm and on this permanent magnet segment 30 directly above and below a soft magnetic segment 22 adjacent, this corresponds a throttle, as shown on the left in Figure 9 with seven columns, in each of which a permanent magnet segment 30 is inserted, these need only have a thickness of 0.495 mm.
- FIG. 10 shows the inductance course of the two inductors shown in FIG. 9 as a function of the current with the same initial inductance of approximately 100 pH.
- the solid line corresponds to the throttle shown in Figure 9 right with a 14 thick permanent magnet segment 30, while the dashed line corresponds to the throttle in Figure 9 left.
- Figure 10 clearly shows that when using more than one permanent magnet segment 30, the inductance curve is shifted to the right.
- more current can be conducted in the choke with the seven permanent magnet segments 30 with the same initial inductance than in the variant with only a single permanent magnet segment 30.
- FIG. 11 shows a further exemplary embodiment of a throttle according to the invention.
- thirteen soft magnetic segments 22 are now provided in total in the stack 20, for example, the permanent magnet segments 30 inserted between these soft magnetic segments 22 being significantly narrower than the remaining components of the stack 20. This means that the soft magnetic segments 22 on the left and right in the sectional view of FIG. 11 project beyond the permanent magnet segments 30. 15
- a narrower permanent magnet segment 30 is inserted between the first and second soft magnetic segment 22, between the eighth and ninth soft magnetic segment 22, and between the twelfth and thirteenth soft magnetic segment 22.
- These permanent magnet segments 30 are 11, between the third and fourth Wexchmagnetsegment 22 and between the tenth and eleventh Wexchmagnetsegment 22 insert an insulator segment 40.
- These insulator segments 40 are in their outer contour equal to the outer contour the soft magnetic segments 22, but may also be formed narrower than this or even wider than this if necessary.
