[0005] Magnetic field-sensitive component, magnetic field-sensitive assembly, inductive assembly and use

[0006] The invention relates to a magnetic field-sensitive component, a magnetic field-sensitive assembly, an inductive assembly and a use.

[0007] Inductive components or assemblies, especially chokes, are used for a multitude of electronic and / or electrical applications, preferably for limiting currents in electrical lines, for intermediate storage of energy in the form of their magnetic field, for impedance matching and / or for filtering an electronic and / or electrical signal, especially for eliminating interference currents in the electrical lines.

[0008] When using such an inductive component or assembly as a suppression choke, direct current and low-frequency currents in the electrical lines should be unaffected or only minimally affected by the choke, while high-frequency alternating currents should be effectively reduced by utilizing the impedance of the inductance of the inductive component or assembly. Page 2 of 64

[0009] P81039DE

[0010] In direct current (DC) networks, connecting lines between electrical components or devices typically have two conductors, which, regardless of the current direction during operation, can be referred to as the supply and return lines. The interference currents that occur in such electrical lines can be divided into common-mode interference currents and differential-mode interference currents, also known simply as common-mode and differential-mode interference. Common-mode interference currents are interference currents on the connecting lines that occur equally on both the supply and return lines. In contrast, differential-mode interference currents do not propagate equally on the connecting lines, but rather, for example, in opposite directions.

[0011] Currently, in corresponding DC networks, it is necessary to use separate components, especially chokes, to filter or attenuate differential-mode and common-mode interference currents. While this has generally proven effective, it is considered disadvantageous in some respects because the corresponding arrangement of these separate components is relatively complex and requires a relatively large amount of installation space.

[0012] Especially for mobile applications and / or other space-sensitive, cost-sensitive, and / or weight-sensitive applications, there is a desire to design the required tasks in a way that is as space-saving, lightweight, cost-effective, and robust as possible. Furthermore, good filtering of high-frequency interference currents, a constant temperature, and good adaptability to the designated application are also desirable. Page 3 / 64

[0013] P81039DE

[0014] The invention is therefore based on the objective of providing an improvement or an alternative to the prior art.

[0015] According to a first aspect, the problem underlying the present invention is solved by a magnetic field-sensitive component with the features of claim 1. Advantageous embodiments of the magnetic field-sensitive component are described in claims 2 to 14, which depend on claim 1.

[0016] In more detail, the problem underlying the present invention is solved by a magnetic field-sensitive component with a ring shape, wherein the magnetic field-sensitive component forms an internal through-opening for the passage of at least one first and one second electrical conductor, and the through-opening extends in a through-direction through the magnetic field-sensitive component, and the magnetic field-sensitive component comprises a soft magnetic material, in particular an amorphous soft magnetic material, further in particular a metallic glass, preferably having a nanocrystalline structure, wherein the through-opening has a first passage area and a second passage area for the passage of the first and the second electrical conductor, wherein a connecting line between the first and second electrical conductor to be passed through is provided.The centers of the first and second passage areas define a width direction perpendicular to the passage direction.

[0017] The magnetic field-sensitive component according to the invention is characterized in that opposing areas of the ring shape have a form such that the through-opening has a height extension in a vertical direction transverse to the width direction and to the through-direction, and a maximum height extension of page 4 / 64

[0018] P81039DE

[0019] The passage opening in the first passage area and in the second passage area is larger than a minimum height extension of the passage opening in an intermediate area located along the connecting line between the first passage area and the second passage area.

[0020] The invention is based on the fundamental idea of ​​creating a magnetic field-sensitive component that can effectively filter or dampen both common-mode and differential-mode interference currents.

[0021] The magnetic field-sensitive component filters, i.e., attenuates or cancels, common-mode interference currents. This attenuation or cancellation of the common-mode interference currents preferably occurs through superposition in the magnetic flux. Since the electrical conductors are typically routed around the magnetic field-sensitive component in opposite regions or through one of the through-sections, the common-mode interference currents each induce a magnetic flux in the magnetic field-sensitive component. The magnetic fluxes based on the common-mode interference currents can superimpose, thereby filtering them, i.e., attenuating or canceling them out. As a result, the common-mode interference currents are filtered by the magnetic field-sensitive component.The magnetic field-sensitive component thus forms a circumferential first magnetic path for filtering common-mode interference currents, i.e., for damping or canceling the common-mode interference currents.

[0022] The magnetic field-sensitive component, on the other hand, filters out, i.e., attenuates or cancels, differential-mode interference currents. For this purpose, a second magnetic path is provided, encompassing the intermediate range where the minimum vertical extent of the through-hole is smaller than the value shown on page 5 / 64.

[0023] P81039DE Maximum height extent of the through-hole in the first through-hole region and in the second through-hole region. The minimum height extent is, for example, greater than zero, so that a constructive gap remains in the intermediate region, i.e., a distance between the inner surfaces of the magnetic field-sensitive component in the intermediate region. The minimum height extent of the through-hole in the intermediate region accordingly defines a gap width of the remaining gap. With a minimum height extent greater than zero, a continuous through-hole typically results, extending through the constructive gap. It is important here that the constructive gap allows a lower magnetic flux in the direction between the opposite regions of the ring shape compared to one circumferential direction of the annular magnetic-sensitive component, which is why the gap is considered a flux gap in terms of its function.In principle, the minimum height extent can also approach zero or be zero, meaning that the opposing regions of the ring shape can be in contact with each other, thus constructively subdividing the through-opening. The resulting gap between the opposing regions of the ring shape can therefore be constructively zero. Even in this case, however, a flux gap exists, which, compared to the circumferential direction of the ring-shaped magnetically sensitive component, allows a lower magnetic flux across the flux gap, i.e., in the direction between the opposing regions of the ring shape. This is particularly true if the permeability of the magnetically sensitive component is lower in its circumferential direction than in a transverse direction, i.e., in a direction between the opposing regions of the ring shape.This applies, for example, if the magnetic field-sensitive component is constructed from layers of soft magnetic material, as further detailed below. The second magnetic path for filtering, i.e., for damping or canceling, differential-mode interference currents therefore includes the resulting flux gap (page 6 / 64).

[0024] P81039DE

[0025] Through-opening in the intermediate region. This second magnetic path has an inductance compared to the first magnetic path formed around the magnetic field-sensitive component for filtering common-mode interference currents, which is well suited for filtering differential-mode interference currents, so that this second magnetic path is designed for filtering differential-mode interference currents, i.e., for attenuating or canceling differential-mode interference currents.This filtering effect of the second magnetic path, taking into account the soft magnetic material of the magnetic field-sensitive component, is achieved by forming a flux gap in the intermediate region. The relative permeability of this flux gap is lower than that of the soft magnetic material, so that, based on the design of the intermediate region with the gap, the second magnetic path for filtering differential-mode interference currents exhibits a significantly lower effective permeability compared to the first magnetic path for filtering common-mode interference currents. The effective permeability is determined by the permeabilities of the entire respective path.

[0026] The second magnetic path encloses the flux gap of the through-opening in the intermediate region and, in particular, filters the differential-mode interference currents for each of the two through-openings. The filtering of common-mode interference currents in the first magnetic path is not affected.

[0027] Advantageously, the magnetic field-sensitive component can be designed such that the first magnetic path has an effective permeability that is greater than or equal to 1.1 times the effective permeability of the second magnetic path, in particular by a factor greater than or equal to 10, preferably by a factor greater than or equal to 100, and most preferably by a factor greater than or equal to 1000. A magnetic field-sensitive component designed in this way (page 7 / 64)

[0028] P81039DE

[0029] The component can react particularly quickly to high-frequency alternating currents and thus better compensate for induced interference currents. The effective permeability is determined from the permeabilities of the entire respective path.

[0030] As a result, the magnetic field-sensitive component according to the invention can efficiently filter, i.e., attenuate or cancel out, both common-mode and differential-mode interference currents. This eliminates the need for separate components or assemblies, preferably designed as inductors, for each type of interference current. Consequently, an electrical system comprising the magnetic field-sensitive component according to the invention can be optimized with regard to filtering effect, installation space, weight, and cost.

[0031] The following terms are explained in this context:

[0032] First, it should be expressly noted that, within the context of this patent application, indefinite articles and numerical terms such as "one", "two", etc., are generally to be understood as "at least" specifications, i.e., as "at least one...", "at least two...", etc., unless it is expressly clear from the respective context or it is obvious or technically necessary for the person skilled in the art that only "exactly one...", "exactly two...", etc., can be meant.

[0033] In the context of the present patent application, the expression "in particular" is always to be understood as introducing an optional, preferred feature. The expression is explicitly not to be understood as "namely" or "indeed".

[0034] A "magnetically sensitive component" is understood to be a component, in particular a ferromagnetic component, which is affected by a magnetic field with a change of at least page 8 / 64

[0035] P81039DE reacts to a state variable of the component. A magnetic field-sensitive component can be used, among other things, together with electrically conductive conductors to create an inductive component that can be used for electrical and / or electronic applications.

[0036] A "through opening" is understood to be a free cross-section that is formed in the interior of the magnetic field-sensitive component and is bounded by its inner surface.

[0037] A "pass-through area" is understood to be a free cross-section extending through the magnetic field-sensitive component, which forms part of the through-opening. The pass-through area can have an oval cross-section, preferably an elliptical or circular cross-section, or any other cross-section, in particular a D-shaped or semicircular cross-section. The pass-through areas are preferably formed on opposite sides of the through-opening. The first pass-through area and the second pass-through area are designed to accommodate the corresponding first and a second electrical conductor.

[0038] The passage areas preferably run along parallel axes in the magnetic field-sensitive component. Preferably, the parallel axes of the passage areas run parallel to an axis of the direction of travel of the passage opening. This further simplifies the process of guiding a designated electrical conductor through the passage opening of the magnetic field-sensitive component and through the corresponding passage area.

[0039] The magnetic field-sensitive component contains a soft magnetic material. A "soft magnetic material" is understood to be a material which, in a magnetic field, [page 9 / 64]

[0040] P81039DE can be easily magnetized. Preferably, a soft magnetic material has a coercive field strength of less than or equal to 1,000 A / m.

[0041] The soft magnetic material can in particular be an amorphous soft magnetic material, especially a metallic glass, which preferably has a nanocrystalline structure.

[0042] Preferably, the soft magnetic material comprises an alloy of iron, nickel and / or cobalt.

[0043] The amorphous atomic arrangement, which is very unusual for metals, advantageously enables special physical material properties. In particular, the use of metallic glass can advantageously reduce the coercive field strength of the magnetic field-sensitive component and / or advantageously increase its permeability.

[0044] A "metallic glass" is understood to be a metal-based alloy of a material which, at the atomic level, does not have a crystalline but rather an amorphous structure, yet still exhibits metallic conductivity. Preferably, metallic glass may contain non-metallic alloying elements in addition to metallic alloying elements.

[0045] Preferably, a soft magnetic material can have the following atomic composition:

[0046] [Fei- a Ni a ] ioo-xyza-ß-Y Cu x Si y B z NbaM' ßM" Y with a < 0.3, 0, 6 < x < 1.5, 10 < y < 17, 5 < z < 14, 2 < a < 6, β < 7, y < 8, where M' is at least one of the elements V, Gr, Co, Al and Zn, where M" is at least one of the elements C, Ge, P, Ga, Sb, In and Be. Page 10 / 64

[0047] P81039DE Further preferably, a soft magnetic material can contain 73.5 wt.% iron and / or 1 wt.% copper and / or 3 wt.% niobium and / or 13.5 wt.% silicon and / or 9 wt.% boron. Advantageously, a soft magnetic material can contain 74.5 wt.% iron and copper, wherein the copper content is less than or equal to 1 wt.%.

[0048] The magnetic field-sensitive component has a ring shape, meaning it features a through-hole extending through the ring. The magnetic field-sensitive component is essentially flat.

[0049] The ring shape can be implemented in various ways. The magnetic field-sensitive component can have a circular outer surface. Alternatively, its outer surface can comprise two opposing, parallel, straight sections connected by semicircular arcs. Another alternative is an oval outer surface. The key element of the ring shape is the opening within it. It's important to note that the inner surface, which borders the opening, and the outer surface of the magnetic field-sensitive component can have different shapes.

[0050] An "oval" is a flat, rounded, convex figure. Ovals include circles and ellipses as special cases, but unlike these, an oval need not possess an axis of symmetry. In particular, an oval is a closed, twice continuously differentiable convex curve in the plane.

[0051] The direction of passage through the magnetic field-sensitive component defines a direction for the passage for the first page 11 / 64

[0052] P81039DE or . second electrical conductor . The magnetic field-sensitive component is preferably designed in a plane perpendicular to the direction of transmission .

[0053] The magnetic field-sensitive component can extend in the direction of travel over a length of at least 1 mm, preferably at least 10 mm, more preferably at least 15 mm, even more preferably at least 20 mm, in particular at least 25 mm, particularly preferably at least 35 mm, and / or at most 100 mm, in particular at most 75 mm, preferably at most 60 mm, particularly preferably at most 40 mm.

[0054] The first and second passage areas for the first and second electrical conductors constitute a section of the opening. Depending on their design, the two passage areas can be adjacent to each other, with the intermediate area being very small. In principle, the two passage areas can be shaped differently. Preferably, however, the two passage areas have the same shape or are symmetrical to each other, for example, mirror-symmetrical along a perpendicular bisector of the connecting line.

[0055] The connecting line between the first and second electrical conductors to be routed, or between the centers of the first and second passage areas, defines a lateral direction perpendicular to the direction of passage. If the first or second electrical conductor passes through the corresponding passage area multiple times, a definition based on the centers of the passage areas is preferable. The centers of the passage areas can be determined geometrically in a known manner. The definition of the lateral direction and the intermediate area are particularly important for the connecting line. Page 12 / 64

[0056] P81039DE

[0057] The altitude direction, the latitude direction, and the transit direction together define an orthogonal coordinate system.

[0058] The maximum height of the opening in the first and second passage areas is preferably the same. In principle, however, the first and second passage areas can have different maximum heights. In that case, the minimum height of the opening in the intermediate area is smaller than the smaller of the maximum heights of the two passage areas.

[0059] The maximum height of the opening in the first and second passage areas can be at least 8 mm, in particular at least 12 mm, preferably at least 15 mm, and / or at most 50 mm, in particular at most 40 mm, preferably at most 30 mm. Particularly preferably, the maximum height is approximately 20 mm.

[0060] Such dimensions have proven advantageous for the damping properties of the magnetic field-sensitive component, particularly for filtering common-mode interference currents. The dimensions can be adapted to the specific application.

[0061] In an advantageous embodiment of the invention, the magnetic field-sensitive component has a profile at least on one side of the connecting line between the first and second electrical conductors or the centers of the first and second passage areas, wherein the magnetic field-sensitive component has a greater distance to the connecting line on its inner side in the first passage area or in the second passage area than on page 13 / 64

[0062] P81039DE

[0063] Intermediate region. The minimum height of the through-hole in the intermediate region can be adjusted by bringing the magnetic field-sensitive component closer to the connecting line with its inner surface. This approach can occur on one side of the connecting line or on both sides. Regardless, the through-hole in the intermediate region is provided with the minimum height that is smaller than the maximum height of the through-hole in the first and second through-hole regions. In principle, the magnetic field-sensitive component can also approach the connecting line multiple times. If the magnetic field-sensitive component approaches the connecting line on both sides, the approach can be independent for each side, i.e.,The approach can vary in intensity and / or occur at different positions along the connecting line.

[0064] In an advantageous embodiment of the invention, the magnetic field-sensitive component has a profile at least on one side of the connecting line between the first and second electrical conductors or the centers of the first and second passage areas, wherein the magnetic field-sensitive component extends with its inner surface over the connecting line in the intermediate area. The minimum height of the passage opening in the intermediate area can thus be adjusted by ensuring that the magnetic field-sensitive component extends with its inner surface over the connecting line and approaches its inner surface on the other side of the connecting line. This approach can occur on one side of the connecting line or on both sides of the connecting line.Regardless, the passage opening in the intermediate area is provided with the minimum height extension, which is less than the maximum height extension of the passage opening in the first and second passage areas. Page 14 / 64.

[0065] P81039DE

[0066] In principle, the magnetic field-sensitive component can have a shape in which its inner surface extends across the connecting line multiple times in the intermediate region. If the magnetic field-sensitive component has a shape in which its inner surface extends across the connecting line on both sides in the intermediate region, the component can be shaped independently on both sides; that is, its inner surface can extend across the connecting line to different distances on each side and / or to different positions along the connecting line.

[0067] In principle, the design of the magnetic field-sensitive component can be chosen independently on both sides of the connecting line. For example, on one side of the connecting line between the first and second electrical conductors or the midpoints of the first and second passage areas, the magnetic field-sensitive component can have a path in which its inner surface approaches or extends beyond the connecting line in the intermediate area, while on the other side, its inner surface can even move away from the connecting line or maintain a constant distance from it in the intermediate area.

[0068] Preferably, the magnetic field-sensitive component can have a corresponding profile on only one side of the connecting line in the intermediate region, such that its inner surface approaches or extends beyond the connecting line. Accordingly, the magnetic field-sensitive component can be located on page 15 / 64

[0069] P81039DE on the other side have a “simple profile” that corresponds, for example, to a circular arc, a straight line or part of an oval.

[0070] The remaining gap or flux gap in the through-opening of the magnetic field-sensitive component in the intermediate region between the through-areas can be centrally located, i.e., the gap lies, for example, on the connecting line, or the gap can be decentralized, i.e., for example, on one or the other side of the connecting line.

[0071] The gap or flux gap in the through-opening of the magnetic field-sensitive component in the intermediate area between the through-areas can be arranged centrally between the through-areas, or the gap is formed along the connecting line closer to the first or to the second through-area.

[0072] In an advantageous embodiment of the invention, the magnetic field-sensitive component has, in a section corresponding to the intermediate region in the width direction, at least one inner and one outer ring element on one side, between which a recess is formed, wherein an inner wall of the inner ring element defines an inside of the magnetic field-sensitive component, and wherein an outer wall of the outer ring element defines an outside of the magnetic field-sensitive component. In a further embodiment, the magnetic field-sensitive component can have further ring elements in the section corresponding to the intermediate region, which are arranged between the inner and outer ring elements. The inner ring element and the outer ring element can be dimensioned independently of each other.Advantageously, the inner ring element and the outer ring element have the same extent in the direction of passage, which simplifies the manufacturing process. Page 16 / 64.

[0073] P81039DE is lighter. Alternatively or additionally, the inner and outer ring elements can have different material thicknesses. This allows the magnetic properties of the inner and outer ring elements to be individually adjusted. Accordingly, the magnetic field-sensitive component can be manufactured with desired magnetic properties, which are also influenced by the magnetic properties of the inner and outer ring elements. Alternatively, the inner and outer ring elements can have the same material thickness. The design of the magnetic field-sensitive component as a multi-part ring element allows for the manufacture of the magnetic field-sensitive component with a particularly free shape. This allows the magnetic field-sensitive component to be shaped independently, especially on its outer and inner surfaces.Particularly in the section corresponding to the intermediate region in the width direction, the magnetic field-sensitive component can have independent configurations on its inner and outer surfaces. This allows the magnetic field-sensitive component, for example, to have an overall oval shape on its outer surface, depending on the shape of the outer ring element, while on its inner surface, depending on the shape of the inner ring element, the magnetic field-sensitive component has a profile that defines the dimensions of the through-opening, with the minimum height of the through-opening in an intermediate region being smaller than the maximum height of the through-opening in the first through-opening region and in the second through-opening region.The design of the magnetic field-sensitive component with at least the inner and outer ring elements also provides simple possibilities for adjusting the magnetic properties of the magnetic field-sensitive component. Thus, the filter properties of the magnetic field-sensitive component for filtering common-mode and / or differential-mode interference currents can be easily adjusted. Page 17 / 64.

[0074] P81039DE

[0075] In an advantageous embodiment of the invention, the inner and outer ring elements have essentially the same length. Such an embodiment enables the simple manufacture of the magnetic field-sensitive component. Furthermore, the magnetic properties of the entire magnetic field-sensitive component can be easily determined and thus adjusted.

[0076] In an advantageous embodiment of the invention, the magnetic field-sensitive component is configured at least on one side as a one-piece ring element in a section corresponding to the intermediate region in the width direction, wherein an inner wall of the ring element defines an inside of the magnetic field-sensitive component, and wherein an outer wall of the ring element defines an outside of the magnetic field-sensitive component. The configuration of the magnetic field-sensitive component as a one-piece ring element enables both simple manufacturing and simple shaping. In particular, in the section corresponding to the intermediate region, the one-piece ring element can have a corresponding outside configuration depending on its inner configuration, with the outside in the first passage area being...The second passage area has a greater distance to the connecting line than the intermediate area, or even extends beyond the connecting line. In principle, even with this design of the magnetic field-sensitive component, the inner and outer surfaces can have independent shapes, for example, if the magnetic field-sensitive component has a different extent in the vertical direction in the area corresponding to the intermediate area, i.e., a different ring thickness or material thickness. Page 18 / 64.

[0077] P81039DE

[0078] In an advantageous embodiment of the invention, the magnetic field-sensitive component has a substantially constant material thickness around its circumference. The material thickness is defined in a direction from the inside of the magnetic field-sensitive component to its outside, which, for example, may involve a vertical extension in the area corresponding to the intermediate region. The material thickness refers to the ring material belonging to the magnetic field-sensitive component, but not, for example, to increases in the distance between the inside and outside of the magnetic field-sensitive component resulting from cutouts in the ring material. Therefore, if the magnetic field-sensitive component is designed as a single-piece ring element, it can have a substantially constant cross-section in the circumferential direction.In a magnetic field-sensitive component designed with at least one inner and an outer ring element, between which a recess is formed, the material thickness between the inner wall of the inner ring element and the outer wall of the outer ring element is the same. This applies accordingly to embodiments of the magnetic field-sensitive component with further ring elements, for example, between the inner and the outer ring element. Due to the essentially constant material thickness, a homogeneous magnetic flux can be generated in the magnetic field-sensitive component. It is particularly advantageous for the magnetic field-sensitive component to be designed with an essentially constant material thickness around its circumference if the magnetic field-sensitive component is built up in layers.The magnetic field-sensitive component can be provided with a uniform layer structure, wherein the magnetic field-sensitive component has the same number of layers over its entire circumference.

[0079] In an advantageous embodiment of the invention, the minimal

[0080] Height extension of the through-opening in the intermediate area, page 19 / 64

[0081] P81039DE, located along the connecting line between the first and second electrical conductors or the midpoints of the first and second passage areas, is selected to adjust an inductance for suppressing differential-mode interference for the first and second electrical conductors. The specific design of this magnetically sensitive component allows the second magnetic path to be adjusted to the required filtering characteristics for the differential-mode interference currents. This adjustment is achieved by changing the width of the resulting gap or flux gap, which corresponds to the minimum height of the passage opening in the intermediate area.

[0082] In addition to the minimum height extension of the through-opening in the intermediate region, other properties of the magnetic field-sensitive component can be modified to adjust the inductance for suppressing differential-mode interference for the first and second electrical conductors, for example, a position of the resulting gap between the two through-areas or a length of the resulting gap.

[0083] In an advantageous embodiment of the invention, the magnetic field-sensitive component is constructed in layers from a soft magnetic material, wherein the magnetic field-sensitive component is, in particular, wound from a soft magnetic material, and wherein, furthermore, the magnetic field-sensitive component is wound circumferentially from a strip. The layered construction allows for a reduction in eddy current losses of the magnetic field-sensitive component. Preferably, the eddy current losses can be specifically adjusted via the layered structure of the soft magnetic material, thereby allowing the eddy current losses and thus the impedance of the magnetic field-sensitive component to be controlled. For example, the eddy current losses and the impedance can be adjusted by the [page 20 / 64]

[0084] P81039DE

[0085] Layer thicknesses can be adjusted. The impedance of the magnetic field-sensitive component can influence and / or adjust its transmission characteristics, particularly its damping, with respect to high-frequency currents. This allows high-frequency currents, especially high-frequency interference currents, to be partially or completely dissipated by the magnetic field-sensitive component. The layering involves a direction from the inside of the magnetic field-sensitive component to its outside, in which the layers are arranged one above the other.

[0086] The layer thickness can be at least 5 pm, in particular at least 10 pm, and / or at most 200 pm, in particular at most 100 pm, preferably at most 25 pm. Particularly preferably the layer thickness is 14 to 24 pm, in particular about 20 pm.

[0087] The total number of layers can be at least 100, in particular at least 250, preferably at least 400, and / or at most 1,500, in particular at most 1,000, preferably at most 600. Particularly preferably, the magnetic field-sensitive component comprises approximately 500 layers.

[0088] In an advantageous embodiment of the invention, the magnetic field-sensitive component has a relative permeability of greater than or equal to 1,000, preferably greater than or equal to 5,000, more preferably greater than or equal to 10,000 and particularly preferably greater than or equal to 20,000.

[0089] Furthermore, the magnetic field-sensitive component can advantageously have a relative permeability of greater than or equal to 30,000, preferably a relative permeability of greater than or equal to 45,000, more preferably a relative permeability of greater than or equal to 60,000, and particularly preferably a relative permeability of greater than or equal to 75,000. Page 21 / 64

[0090] P81039DE

[0091] According to an optional embodiment, the magnetic field-sensitive component can have a relative permeability of less than or equal to 150,000, preferably a relative permeability of less than or equal to 100,000, more preferably a relative permeability of less than or equal to 90,000, and particularly preferably a relative permeability of less than or equal to 75,000. The relative permeability is preferably measured with a magnetic field oscillating at 50 Hz. The relative permeability values ​​proposed above for the magnetic field-sensitive component are particularly suitable for compensating common-mode interference currents, especially high-frequency common-mode interference currents induced on the load side or the grid side.

[0092] Permeability is a measure of a material's magnetization in an external magnetic field. The higher the permeability of a magnetically sensitive component, the greater the ratio of magnetic flux density within the component to the magnetic field strength acting upon it. Thus, a magnetically sensitive component with high permeability results in a comparatively high magnetic flux density even at low magnetic field strengths. The permeability p is calculated as the product of the relative permeability p R , also known as permeability number , formed with the magnetic field constant p₀ (p = p₀ R p0) .

[0093] In an advantageous embodiment of the invention, the magnetic field-sensitive component has a magnetic saturation flux density of greater than or equal to 1 T, preferably greater than or equal to 1.2 T, and particularly preferably greater than or equal to 1.4 T. This allows, for example, the magnetic field-sensitive component to be used as an inductive (page 22 / 64).

[0095] Even with comparatively large interference currents, it is possible to ensure that the magnetic field-sensitive component is not driven into a saturation state and that the interference currents can be filtered accordingly.

[0096] The "saturation flux density" is a measure of the maximum extent to which a material can be magnetized by an applied magnetic field. The flux density initially increases continuously with increasing field strength. Above a certain value, this effect diminishes sharply, so that a further increase in field strength leads only to a very small increase in the flux density in the material. The flux density at which this flattening occurs is called the saturation flux density.

[0097] In an advantageous embodiment of the invention, the magnetic field-sensitive component has a coercive field strength of less than or equal to 10 A / m, preferably a coercive field strength of less than or equal to 5 A / m, and particularly preferably a coercive field strength of less than or equal to 3 A / m. This results in reduced heat loss due to a changing magnetic field in the magnetic field-sensitive component. In this way, the magnetic field-sensitive component can be dimensioned even smaller while maintaining constant common-mode interference currents, thus improving the power density of the magnetic field-sensitive component. Such coercive field strengths also support the attenuation of differential-mode interference currents. The term "coercive field strength" refers to the magnetic field strength required to completely demagnetize a magnetic field-sensitive component that has been previously charged to its saturation flux density.

[0098] In an advantageous embodiment of the invention, the through-opening has a through-opening width in the width direction (page 23 / 64).

[0099] P81039DE, and the intermediate area has an intermediate area width in the lateral direction, wherein the intermediate area width is less than 80% of the through-opening width, preferably less than 70% of the through-opening width, particularly preferably less than 60% of the through-opening width, and / or the intermediate area width is greater than 20% of the through-opening width, preferably greater than 30% of the through-opening width, particularly preferably greater than 40% of the through-opening width. Corresponding size ratios have proven advantageous in practice for efficiently filtering both common-mode and differential-mode interference currents with the magnetic field-sensitive component.The detailed dimensions can be adapted to the specific application, for example to the dimensions of the first and / or second conductor, the number of windings of the first and / or second conductor around the magnetic field-sensitive component, as well as to a desired filtering effect.

[0100] In an advantageous embodiment of the invention, the minimum height extent of the through-opening in the intermediate region has a maximum extent of 1.0 mm, preferably a maximum extent of 0.7 mm, more preferably a maximum extent of 0.5 mm, and particularly preferably an extent of approximately 0 mm. In practice, these absolute values ​​of the height extent of the through-opening in the intermediate region have proven advantageous for conventional magnetic field-sensitive components with standard dimensions in order to efficiently filter common-mode and differential-mode interference currents with the magnetic field-sensitive component and, in particular, to provide the second magnetic path for filtering the differential-mode interference currents in a suitable manner. The magnetic field-sensitive component can, for example, be easily manufactured if the minimum height extent of the [page 24 / 64]

[0101] P81039DE

[0102] The through-opening in the intermediate region is zero or approaches zero, since the opposing areas of the ring shape only need to be brought into contact. The detailed design of the magnetic field-sensitive component with regard to the minimum height extent can be adapted to a specific application, for example, to the dimensions of the first and / or second conductor, the number of windings of the first and / or second conductor around the magnetic field-sensitive component, as well as to a desired filtering effect.

[0103] Regarding the minimum height extent of the through-hole in the intermediate region, it has already been explained above that the minimum height extent can be greater than zero, so that a constructive gap remains in the intermediate region, i.e., a distance between the inner surfaces of the magnetic field-sensitive component in the intermediate region. Alternatively, the minimum height extent can approach zero or be zero, i.e., the opposing areas of the ring shape can be in contact with each other, thus constructively subdividing the through-hole. The resulting gap between the opposing areas of the ring shape can therefore be constructively zero, with a flux gap being present in each case, allowing a lower magnetic flux compared to the circumferential direction of the ring-shaped magnetic field-sensitive component.The flux gap therefore causes a lower magnetic flux in the direction between the opposite areas of the ring shape compared to the circumferential direction of the ring-shaped magnetically sensitive component.

[0104] The explanations regarding the flux gap apply particularly when the magnetic field-sensitive component is constructed in layers from the soft magnetic material. The layers are typically arranged in a ring shape on top of each other, for example, by winding the magnetic field-sensitive component from the soft magnetic material, especially around a band. (See page 25 / 64)

[0105] In one case, the permeability in a direction transverse to the layers is lower than in the circumferential direction of the ring-shaped magnetically sensitive device, i.e., in the direction along the layers. This can result in a flux gap in the direction of the second magnetic path.

[0106] According to a second aspect, the problem underlying the present invention is solved by a magnetic field-sensitive assembly with the features of claim 15. Advantageous embodiments of the magnetic field-sensitive assembly are described in claims 16 and 17, which depend on claim 15.

[0107] More precisely, the problem underlying the present invention according to the second aspect is solved by a magnetic field-sensitive assembly with a magnetic field-sensitive component according to one of the preceding claims 1 to 14.

[0108] The magnetic field-sensitive assembly according to the invention is characterized in that the magnetic field-sensitive assembly has an insulating housing in which the magnetic field-sensitive component is received.

[0109] It is understood that the advantages of the magnetic field-sensitive component according to the first aspect of the invention, as described above, extend directly to the magnetic field-sensitive assembly according to the second aspect of the invention, which comprises the magnetic field-sensitive component according to the first aspect of the invention.

[0110] It should be expressly noted that the subject matter of the second aspect can be advantageously combined with the subject matter of the preceding aspect of the invention, either individually or cumulatively in any combination. Page 26 / 64

[0111] P81039DE

[0112] An "insulating housing" is a component that electrically isolates the magnetic field-sensitive component from its environment.

[0113] The insulating housing can be made of a plastic, in particular a thermoplastic and / or a thermosetting plastic, or may contain such a material.

[0114] Advantageously, the insulating housing can be manufactured or produced using an injection molding process and / or a thermoforming process and / or a PUR-RIM process and / or another plastic manufacturing process from a thermoplastic and / or a thermoset.

[0115] The insulating housing can at least partially enclose the magnetic field-sensitive component, and in particular, completely enclose it. "Completely enclose" means that the insulating housing surrounds the magnetic field-sensitive component along its inner surface, outer surface, and connection sides, either completely or with cutouts. The insulating housing can be shaped to match the ring shape of the magnetic field-sensitive component, possibly with some play. The insulating housing can therefore have a ring shape corresponding to the magnetic field-sensitive component.

[0116] In the insulating housing, the first and second passage areas are at least partially opened, so that the first and second electrical conductors can be routed through the first and second passage areas accordingly.

[0117] Preferably, the housing has a temperature resistance of greater than or equal to 120 °C, more preferably a temperature resistance of greater than or equal to 150 °C, and most preferably a temperature resistance of greater than or equal to 180 °C. Page 27 / 64

[0118] P81039DE

[0119] In an advantageous embodiment of the invention, the insulating housing is designed as a coating on the magnetic field-sensitive component. The magnetic field-sensitive component can thus be immersed, for example, in a liquid plastic material, so that the material adheres to the magnetic field-sensitive component and solidifies, forming the insulating housing after solidification. Solidification can be achieved, in particular, by cooling the liquid plastic material. Alternatively, plastics are also known that solidify, for example, by irradiation with UV light. Designing the insulating housing as a coating on the magnetic field-sensitive component enables simple manufacturing of the magnetic field-sensitive assembly and, moreover, reliable insulation of the magnetic field-sensitive component.

[0120] In an advantageous embodiment of the invention, the insulating housing is designed as a separate housing, in particular as a plastic housing, especially made of an injection-molded material, and the magnetic field-sensitive component is enclosed in the plastic housing. The insulating housing can be formed in one piece around the magnetic field-sensitive component. Alternatively, the insulating housing is designed as at least two parts, in particular exactly two parts. Preferably, the insulating housing comprises a housing shell and a housing cover. A multi-part housing can be manufactured separately from the magnetic field-sensitive component and attached around it, which simplifies manufacturing.

[0121] According to a third aspect, the problem underlying the present invention is solved by an inductive assembly with the features of claim 18.

[0122] More precisely, the problem underlying the present invention according to the third aspect is achieved by an inductive assembly comprising a magnetic field-sensitive assembly according to page 28 / 64

[0123] P81039DE one of the preceding claims 15 to 17 and at least a first and a second electrical conductor solved; wherein the first electrical conductor is passed at least once through the first passage area; and the second electrical conductor is passed at least once through the second passage area.

[0124] It is understood that the advantages of the magnetic field-sensitive component according to the first aspect of the invention and the magnetic field-sensitive assembly according to the second aspect of the invention, as described above, extend directly to the inductive assembly according to the third aspect of the invention, which comprises the magnetic field-sensitive assembly according to the second aspect of the invention and, above it, the magnetic field-sensitive component according to the first aspect of the invention.

[0125] It should be expressly noted that the subject matter of the third aspect can be advantageously combined with the subject matter of the preceding aspects of the invention, either individually or cumulatively in any combination.

[0126] The first electrical conductor and / or the second electrical conductor can be designed as a busbar. Such a busbar is typically routed once through the corresponding passage area. Alternatively, the first electrical conductor and / or the second electrical conductor can be designed as a stranded conductor with multiple individual strands or wires. Another alternative is that the first electrical conductor and / or the second electrical conductor can be designed as a solid conductor with a single conductor wire. Solid conductors as well as stranded conductors can each be routed once through the corresponding passage area, or multiple times by wrapping the respective electrical conductor around the magnetic field-sensitive component in the area of ​​the passage opening. Regardless of the design, the respective electrical properties are described on page 29 / 64.

[0127] P81039DE

[0128] Conductors preferably designed with insulation and / or shielding.

[0129] Once the first and / or second electrical conductor has passed through the relevant passage area, it can, in principle, be positioned anywhere within it, for example, in the center. Alternatively, the first and / or second electrical conductor can be positioned at the edge of the passage area, i.e., adjacent to the magnetic field-sensitive component. If the first and / or second electrical conductor has passed through the relevant passage area multiple times, the second electrical conductor is typically positioned at the edge of the passage area, i.e., adjacent to the magnetic field-sensitive component. In this case, the electrical conductor is preferably wound tightly around the magnetic field-sensitive component within the relevant passage area.

[0130] According to a fourth aspect, the problem underlying the present invention is solved by the use of a magnetic field-sensitive assembly with the features of claim 19.

[0131] In more detail, the problem underlying the present invention according to the fourth aspect is solved by using a magnetic field-sensitive assembly according to one of claims 15 to 17 as an inductive component, in particular for reducing common-mode and / or differential-mode interference for at least one first and one second electrical conductor in the state accordingly guided through the first passage area and the second passage area.

[0132] It is understood that the advantages of the magnetic field-sensitive component are evident from the first aspect of the invention and page 30 / 64.

[0133] P81039DE magnetic field-sensitive assembly according to the second aspect of the invention, as described above, directly extends to the use of the magnetic field-sensitive assembly according to the fourth aspect of the invention, which comprises the magnetic field-sensitive assembly according to the second aspect of the invention and, above that, the magnetic field-sensitive component according to the first aspect of the invention.

[0134] It should be expressly noted that the subject matter of the fourth aspect can be advantageously combined with the subject matter of the preceding aspects of the invention, either individually or cumulatively in any combination.

[0135] Advantageously, a magnetic field-sensitive assembly can be used as an inductive component or inductive assembly in a power supply system, preferably in a DC power supply system and particularly preferably in a DC power supply system for powering a battery-electric storage device.

[0136] The power supply system can be designed as a charger, in particular as a charger for a vehicle having a battery-electric storage device, preferably for a battery electric vehicle (BEV), and more preferably for a battery-electric commercial vehicle.

[0137] Alternatively, the power supply system, particularly as a direct current (DC) power supply system, can be configured to supply an electrical load with current, in particular an electric drive unit, preferably an electric motor, especially an electric motor of a vehicle, most preferably from a battery storage system. Page 31 / 64

[0138] P81039DE

[0139] The power supply system can include at least one frequency converter.

[0140] Further advantages, details, and features of the invention will become apparent from the illustrated examples below. Specifically, the following will be shown:

[0141] Figure 1: a schematic representation of a magnetic field-sensitive component with a through-opening having two through-areas, according to a first, preferred embodiment in top view, wherein the magnetic field-sensitive component is formed in one piece on both sides of a connecting line between the two through-areas and has a profile on one side of the connecting line, wherein the magnetic field-sensitive component extends with its inner side over the connecting line;

[0144] P81039DE

[0145] From a top view, the magnetic field-sensitive component is formed in one piece on both sides of a connecting line between the two passage areas and has a profile on both sides of the connecting line, wherein the magnetic field-sensitive component has a greater distance to the connecting line on its inner side in the first passage area and in the second passage area than in an intermediate area lying between the passage areas; and

[0147] In the following description, the same reference symbols denote the same components or the same features, so that a description given for one component in relation to one figure also applies to the other figures, thus avoiding repetitive descriptions. Furthermore, individual features described in connection with one embodiment can also be used separately in other embodiments. Page 33 / 64

[0148] P81039DE

[0149] Figure 1 shows a representation of a magnetic field-sensitive component 1 according to a first embodiment of the present invention.

[0150] As can be seen in Figure 1, the magnetic field-sensitive component 1 is flat and ring-shaped. Thus, the magnetic field-sensitive component 1 forms an internal opening 2 for the passage of at least one first and one second electrical conductor. The first electrical conductor and / or the second electrical conductor can be configured as a busbar. Alternatively, the first electrical conductor and / or the second electrical conductor can be configured as a stranded conductor with multiple individual strands or wires. As a further alternative, the first electrical conductor and / or the second electrical conductor can be configured as a wire conductor with a single conductor wire.Wire conductors as well as stranded conductors can each be passed once through the corresponding passage area, or multiple times by wrapping the corresponding electrical conductor around the magnetic field-sensitive component 1 in the area of ​​the passage opening 2. Regardless of the configuration, the respective electrical conductors are preferably provided with insulation and / or shielding.

[0151] The through-opening 2 extends in a through-direction 3 through the magnetic field-sensitive component 1. In this embodiment, the magnetic field-sensitive component 1 extends in through-direction 3 over a length of approximately 35 mm.

[0152] The magnetic field-sensitive component 1 comprises a soft magnetic material, which in this exemplary embodiment is designed as an amorphous soft magnetic material, in particular as metallic glass, and has a nanocrystalline structure. Page 34 / 64

[0153] P81039DE

[0154] A “soft magnetic material” is understood to be a material which can be easily magnetized in a magnetic field and, in this embodiment, has a coercive field strength of less than or equal to 1,000 A / m.

[0155] A “metallic glass” is understood to be a metal-based alloy of a material which, at the atomic level, does not have a crystalline but an amorphous structure and yet exhibits metallic conductivity as a property.

[0156] In this embodiment, the soft magnetic material comprises an alloy of iron, nickel and / or cobalt with the following atomic composition:

[0157] [Fei- a Ni a ] ioo-xyza-ß-Y Cu x Si y B z NbaM' ßM" Ywith a < 0.3, 0, 6 < x < 1.5, 10 < y < 17, 5 < z < 14, 2 < a < 6, ß < 7, y < 8, where M' is at least one of the elements V, Gr, Co, Al and Zn, where M" is at least one of the elements C, Ge, P, Ga, Sb, In and Be.

[0158] In this embodiment, the soft magnetic material can contain 73.5 wt.% iron and / or 1 wt.% copper and / or 3 wt.% niobium and / or 13.5 wt.% silicon and / or 9 wt.% boron.

[0159] The passage opening 2 includes a first passage area

[0160] 4 and a second passage area 5 for the passage of the first and second electrical conductors. A connecting line 6 between the first and second electrical conductors to be passed through, or between the centers of the first and second passage areas 4 and 5, defines a lateral direction 7 perpendicular to the passage direction 3. The two passage areas 4,

[0161] 5 are symmetrically designed with respect to a perpendicular bisector of the connecting line 6. Page 35 / 64

[0162] P81039DE

[0163] Between passage areas 4 and 5, an intermediate area 8 remains, located along the connecting line 6 between the first passage area 4 and the second passage area 5. Passage areas 4 and 5, together with intermediate area 8, thus form passage opening 2.

[0164] The through-opening 2 has a height extent in a vertical direction 9 perpendicular to the horizontal direction 7 and the through-direction 3. The maximum height extent 10 of the through-opening 2 in the first through-area 4 and in the second through-area 4 is greater than the minimum height extent 11 of the through-opening 2 in the intermediate area 8, which is located between the two through-areas 4 and 5. The minimum height extent 11 of the through-opening 2 in the intermediate area 8 is greater than zero, so that a gap 12 remains in the intermediate area 8, i.e., a distance between opposing inner surfaces 13 of the magnetic field-sensitive component 1. The gap 12 is therefore a constructive gap 12. The minimum height extent 11 thus defines a gap width of the remaining gap 12 .The maximum height extension 10 of the passage opening 2 in the first passage area 4 and in the second passage area 5 is the same in this embodiment and is approximately 20 mm.

[0165] In this exemplary embodiment, the magnetic field-sensitive component 1 is designed as a single-piece ring element, wherein the inner wall of the ring element defines an inner surface 13 of the magnetic field-sensitive component 1, and wherein an outer wall of the ring element defines an outer surface 14 of the magnetic field-sensitive component 1. The magnetic field-sensitive component 1 has a constant material thickness 15 around its circumference. The material thickness 15 is defined in a direction from the inner surface 13 of the magnetic field-sensitive component 1 to its outer surface 14, which, for example, corresponds to the intermediate area 8 (page 36 / 64).

[0166] P81039DE has an extension in the vertical direction 9. The magnetic field-sensitive component 1 therefore has a constant cross-section in the circumferential direction.

[0167] In this embodiment, the ring shape of the magnetic field-sensitive component 1 is identical on its outer surface 14 and its inner surface 13. The magnetic field-sensitive component 1 thus has two essentially semicircular sections 16, which define the passage opening 2 in the width direction 7. In Figure 1, above the connecting line 6, a straight section 17 connects the two semicircular sections 16. In Figure 1, below the connecting line 6, the magnetic field-sensitive component 1 has a curved section 18 that connects the two semicircular sections 16 below the connecting line 6. The curved section 18 has a profile in which the magnetic field-sensitive component 1 extends completely across the connecting line 6 in a section corresponding to the intermediate area 8.This means that the gap 12 is located off-center above the connecting line 6. Furthermore, the gap 12 is located centrally between the passage areas 4 and 5 in the width direction 7.

[0168] In this embodiment, the minimum height extent 11 of the passage opening 2 in the intermediate area 8 lies in a range between 10% and 50% of the maximum height extent of the first and second passage areas 4, 5.

[0169] In this embodiment, the passage opening 2 has a passage opening width 19 in the width direction 7, and the intermediate area 8 has an intermediate area width 20 in the width direction 7, wherein the intermediate area width 20 in this embodiment is less than 60% of the passage opening width 19, but greater than 30% of the passage opening width 19. Page 37 / 64

[0170] P81039DE

[0171] In this embodiment, the magnetic field-sensitive component 1 is constructed in layers from the soft magnetic material, with the magnetic field-sensitive component 1 being wound from a continuous strip. The layering is arranged in a direction from the inner side 13 of the magnetic field-sensitive component 1 to its outer side 14, in which the layers are arranged one above the other. The layer thickness in this embodiment is approximately 20 pm. The magnetic field-sensitive component 1 comprises approximately 500 layers in this embodiment. It follows that the magnetic field-sensitive component 1 has a relative permeability of greater than or equal to 75,000, where the relative permeability is measured with a magnetic field oscillating at 50 Hz. Furthermore, the magnetic field-sensitive component 1 has a magnetic saturation flux density of greater than or equal to 1.4 T and a coercive field strength of less than or equal to 3 A / m.

[0172] The magnetic field-sensitive component 1 filters, i.e., attenuates or cancels, common-mode interference currents in the electrical conductors passing through it. This attenuation or cancellation of the common-mode interference currents occurs through superposition of the magnetic fluxes. Since the electrical conductors are typically routed around the magnetic field-sensitive component 1 in opposite regions or through a passage 4, 5, each common-mode interference current induces a magnetic flux in the magnetic field-sensitive component 1. These magnetic fluxes can superimpose, thereby filtering them, i.e., attenuating or canceling them out. The magnetic field-sensitive component 1 thus forms a circumferential first magnetic path 21 for filtering the common-mode interference currents.

[0173] On the other hand, the magnetic field-sensitive component 1 causes the

[0174] Filtering, i.e., attenuation or cancellation, from page 38 / 64

[0175] P81039DE

[0176] Differential-mode interference currents in through-hole electrical conductors. For this purpose, a second magnetic path 22 is provided, which encompasses the intermediate region 8 in which the minimum height extent 11 of the through-hole 2 is smaller than the maximum height extent 10 of the through-hole 2 in the first through-hole 4 and in the second through-hole 5. The second magnetic path 22 for filtering differential-mode interference currents thus encompasses the resulting gap 12 of the through-hole 2 in the intermediate region 8. This second magnetic path 22 has an inductance relative to the first magnetic path 21 formed around the circumference by the magnetic field-sensitive component 1 for filtering common-mode interference currents, which is well suited for filtering the differential-mode interference currents.This filtering effect of the second magnetic path 22, taking into account the soft magnetic material of the magnetic field-sensitive component 1, is achieved by forming a gap 12 in the intermediate region 8. The relative permeability of this gap is lower than that of the soft magnetic material, so that, based on the configuration of the intermediate region 8 with the gap 12, the second magnetic path 22 for filtering differential-mode interference currents has a significantly lower effective permeability compared to the first magnetic path 21 for filtering common-mode interference currents. The effective permeability is determined based on the permeabilities of the entire respective path.

[0177] Based on these considerations, the minimum height extension 11 of the through-opening 2 in the intermediate area 8 is chosen to set an inductance to suppress differential-mode interference for the first and the second electrical conductor.

[0178] In addition to the minimum height extension 11 of the through-opening 2 in the intermediate region 8, further properties of the magnetic field-sensitive component 1 can be modified, as described on page 39 / 64.

[0179] P81039DE allows the magnetic properties of the first and second magnetic paths 21, 22 to be adjusted. In particular, the inductance for suppressing differential-mode interference can be adjusted for the first and second electrical conductors.

[0180] Overall, the magnetic field-sensitive component 1 in this embodiment is designed such that the first magnetic path 21 has an effective permeability that is greater than or equal to 1,000 times greater than the effective permeability of the second magnetic path 22.

[0181] In a modified embodiment not shown in the figures, the minimum height extent 11 of the through-opening 2 in the intermediate region 8 has a dimension of 0 mm, so that the opposing regions of the ring shape come into contact in the intermediate region 8. This constructively subdivides the through-opening 2, and the resulting gap 12 between the opposing regions of the ring shape is constructively zero. However, even in this case, a gap 12 exists in the form of a flux gap, which allows a lower magnetic flux relative to the circumferential direction of the ring-shaped magnetic-sensitive component 1. The magnetic flux in the direction between the opposing regions of the ring shape is therefore lower than in the circumferential direction of the ring-shaped magnetic-sensitive component 1.This occurs because the permeability of the magnetically sensitive component 1 is lower in its circumferential direction than in a transverse direction, i.e., in a direction between the opposite regions of the ring shape, since the magnetically sensitive component 1 is constructed in layers of the soft magnetic material. The layers of the soft magnetic material are arranged in a ring shape on top of each other within the magnetically sensitive component 1. Therefore, the permeability is lower in a direction transverse to the layers (page 40 / 64).

[0182] P81039DE as in the circumferential direction of the ring-shaped magnetically sensitive component 1, i.e. in the direction along the layers. This results in the gap 12 as a flux gap in the direction of the second magnetic path 22.

[0183] Figure 2 shows a representation of a magnetic field-sensitive component 1 according to a second embodiment of the present invention.

[0184] The magnetic field-sensitive component 1 of the second embodiment largely corresponds to the magnetic field-sensitive component 1 of the first embodiment, so that identical features are not described again in detail. Where necessary and unless otherwise specified, features of the magnetic field-sensitive component 1 of the second embodiment correspond to those of the magnetic field-sensitive component 1 of the first embodiment.

[0185] As can be seen in Figure 2, the magnetic field-sensitive component 1 is also planar and has a ring shape. Thus, the magnetic field-sensitive component 1 forms an internal opening 2 for the passage of at least one first and one second electrical conductor. The opening 2 extends through the magnetic field-sensitive component 1 in a direction 3. In this embodiment, the magnetic field-sensitive component 1 extends in the direction 3 over a length of approximately 35 mm.

[0186] The magnetic field-sensitive component 1 of the second embodiment comprises a soft magnetic material, which in this exemplary embodiment is designed as an amorphous soft magnetic material, in particular as metallic glass, and has a nanocrystalline structure. The soft magnetic material corresponds to that of the first embodiment. Page 41 / 64

[0187] P81039DE

[0188] As shown in Figure 2, the passage opening 2 comprises a first passage area 4 and a second passage area 5 for the passage of the first and second electrical conductors. A connecting line 6 between the first and second electrical conductors to be passed through, or between the centers of the first and second passage areas 4 and 5, defines a lateral direction 7 perpendicular to the passage direction 3. The two passage areas 4 and 5 are symmetrical with respect to a perpendicular bisector of the connecting line 6.

[0189] Here too, an intermediate area 8 remains between the passage areas 4 and 5, which is located along the connecting line 6 between the first passage area 4 and the second passage area 5.

[0190] The through-opening 2 has a height extent in a vertical direction 9 perpendicular to the horizontal direction 7 and the through-direction 3. The maximum height extent 10 of the through-opening 2 in the first through-area 4 and in the second through-area 4 is greater than the minimum height extent 11 of the through-opening 2 in the intermediate area 8, which is located between the two through-areas 4 and 5. The minimum height extent 11 of the through-opening 2 in the intermediate area 8 is greater than zero, so that a gap 12 remains in the intermediate area 8, i.e., a distance between opposing inner surfaces 13 of the magnetic field-sensitive component 1 in the intermediate area 8. The minimum height extent 11 thus defines a gap width of the remaining gap 12.The maximum height extension 10 of the passage opening 2 in the first passage area 4 and in the second passage area 5 is the same in this embodiment and is approximately 20 mm.

[0191] In the second embodiment, the magnetic field-sensitive component 1 is only partially designed as a one-piece ring element, with the inner wall of the ring element having an inner surface 13 (page 42 / 64).

[0192] P81039DE of the magnetic field-sensitive component 1 is defined, and wherein an outer wall of the ring element defines an outer surface 14 of the magnetic field-sensitive component 1.

[0193] The magnetic field-sensitive component 1 of the second embodiment thus has, in accordance with the magnetic field-sensitive component 1 of the first embodiment, two essentially semicircular sections 16 which define the through-opening 2 in the width direction 7. In Figure 2, above the connecting line 6, a straight section 17 connects the two semicircular sections 16. In the semicircular sections 16 and the straight section 17, the ring shape of the magnetic field-sensitive component 1 is identical on its outer surface 14 and its inner surface 13.

[0194] In Figure 2 below the connecting line 6, the magnetic field-sensitive component 1 has a two-part section 23 that connects the two semicircular sections 16 below the connecting line 6.

[0195] In this two-part section 23, which corresponds in the width direction 7 with the intermediate area 8, the magnetic field-sensitive component 1 has an inner and an outer ring element 24, 25, between which a recess 26 is formed.

[0196] Accordingly, an inner wall of the inner ring element 24 forms an inner surface 13 of the magnetic field-sensitive component 1, and an outer wall of the outer ring element 25 forms an outer surface 14 of the magnetic field-sensitive component 1. The inner ring element 24 and the outer ring element 25 have the same extent in the direction of passage 3. Page 43 / 64

[0197] P81039DE

[0198] The two-part section 23 of the magnetic field-sensitive component 1 has a profile in which the inner ring element 24 extends completely across the connecting line 6 in a section corresponding to the intermediate region 8. This results in the gap 12 in Figure 2 being arranged off-center above the connecting line 6. Furthermore, the gap 12 is positioned centrally between the passage regions 4 and 5 in the lateral direction 7. The outer ring element 25 is also straight, in accordance with the shape of the straight section 17 above the connecting line 6. Consequently, the magnetic field-sensitive component 1, with its two-part section 23 corresponding to the intermediate region 8 in the lateral direction 7, has independent configurations on its inner side 13 and its outer side 14.

[0199] The magnetic field-sensitive component 1 has a constant material thickness 15 around its circumference. The material thickness 15 is measured in a direction from the inner surface 13 of the magnetic field-sensitive component 1 to its outer surface 14, which, for example, in a region corresponding to the intermediate area 8, represents an extension in the vertical direction 9. The material thickness 15 refers to the ring material belonging to the magnetic field-sensitive component 1, but not to any increase in the distance between the inner surface 13 and the outer surface 14 of the magnetic field-sensitive component 1 resulting from the cutouts 26 in the ring material.

[0200] In this exemplary embodiment, the minimum height extent 11 of the passage opening 2 in the intermediate area 8 lies in a range between 10% and 50% of the maximum height extent of the first and second passage areas 4, 5.

[0201] In this exemplary embodiment, the passage opening 2 has a passage opening width 19 in the width direction 7, and page 44 / 64

[0202] P81039DE

[0203] The intermediate area 8 has an intermediate area width 20 in the width direction 7, wherein the intermediate area width 20 in this embodiment is less than 60% of the passage opening width 19, but greater than 30% of the passage opening width 19.

[0204] The magnetic field-sensitive component 1 of the second embodiment is constructed from a layered soft magnetic material, as described above with reference to the magnetic field-sensitive component 1 of the first embodiment. The descriptions of the construction of the magnetic field-sensitive component 1 therefore apply accordingly. The same applies to the filtering effect of the magnetic field-sensitive component 1 with regard to the filtering of common-mode interference currents of the first embodiment as well as differential-mode interference currents in through-hole electrical conductors. The circumferential first magnetic path 21 includes both the inner ring element 24 and the outer ring element 25. The second magnetic path 22 includes the gap 12 in the intermediate region 8, in which the minimum height extent 11 of the through-hole 2 is smaller than the maximum height extent 10 of the through-hole 2 in the first through-hole 4 and in the second through-hole 5.Of the two-part section 23, the inner ring element 24 in particular contributes to the second magnetic path 22. The further explanations regarding the filtering effect of the first and second magnetic paths 21 and 22, as well as the inductance and magnetic properties, apply accordingly, as with the magnetic field-sensitive component 1 of the first embodiment.

[0205] Figure 3 shows a representation of a magnetic field-sensitive component 1 according to a third embodiment of the present invention.

[0206] The magnetic field-sensitive component 1 of the third embodiment largely corresponds to the magnetic field-sensitive component on page 45 / 64.

[0207] P81039DE

[0208] Component 1 of the first embodiment, so that identical features are not described again in detail. Unless otherwise specified, these features correspond to those of the magnetic field-sensitive component 1 of the first embodiment.

[0209] As can be seen from Figure 3, the magnetic field-sensitive component 1 shown there is also planar and has a ring shape. Thus, the magnetic field-sensitive component 1 forms an internal opening 2 for the passage of at least one first and one second electrical conductor. The opening 2 extends through the magnetic field-sensitive component 1 in a direction 3. In this embodiment, the magnetic field-sensitive component 1 extends in the direction 3 over a length of approximately 35 mm.

[0210] The magnetic field-sensitive component 1 of the third embodiment comprises a soft magnetic material, which in this exemplary embodiment is designed as an amorphous soft magnetic material, in particular as metallic glass, and has a nanocrystalline structure. The soft magnetic material corresponds to that of the first embodiment.

[0211] As shown in Figure 3, the through-opening 2 comprises a first through-area 4 and a second through-area 5 for the passage of the first and second electrical conductors. A connecting line 6 between the first and second electrical conductors to be passed through, or between the centers of the first and second through-areas 4 and 5, defines a lateral direction 7 perpendicular to the passage direction 3. The two through-areas 4 and 5 are symmetrical with respect to a perpendicular bisector of the connecting line 6. Page 46 / 64

[0212] P81039DE

[0213] Here too, an intermediate area 8 remains between the passage areas 4 and 5, which is located along the connecting line 6 between the first passage area 4 and the second passage area 5.

[0214] The through-opening 2 has a height extent in a vertical direction 9 perpendicular to the horizontal direction 7 and the through-direction 3. The maximum height extent 10 of the through-opening 2 in the first through-area 4 and in the second through-area 4 is greater than the minimum height extent 11 of the through-opening 2 in the intermediate area 8, which is located between the two through-areas 4 and 5. The minimum height extent 11 of the through-opening 2 in the intermediate area 8 is greater than zero, so that a gap 12 remains in the intermediate area 8, i.e., a distance between opposing inner surfaces 13 of the magnetic field-sensitive component 1 in the intermediate area 8. The minimum height extent 11 thus defines a gap width of the remaining gap 12.The maximum height extension 10 of the passage opening 2 in the first passage area 4 and in the second passage area 5 is the same in this embodiment and is approximately 20 mm.

[0215] The magnetic field-sensitive component 1 of the third embodiment is designed as a single-piece ring element, wherein the inner wall of the ring element defines an inner surface 13 of the magnetic field-sensitive component 1, and wherein an outer wall of the ring element defines an outer surface 14 of the magnetic field-sensitive component 1. The magnetic field-sensitive component 1 has a constant material thickness 15 over its circumference. The material thickness 15 is measured in a direction from the inner surface 13 of the magnetic field-sensitive component 1 to its outer surface 14, which, for example, in a region corresponding to the intermediate area 8, has a vertical extent 9. The magnetic field-sensitive component 1 is described on page 47 of 64.

[0216] The magnetically sensitive component 1 (P81039DE) therefore has a constant cross-section in the circumferential direction. In this embodiment, the ring shape of the magnetically sensitive component 1 is identical on its outer surface 14 and its inner surface 13.

[0217] The magnetic field-sensitive component 1 has two ring segment sections 27, which define the passage opening 2 in the width direction 7. In Figure 3, an arc segment 28 connects the two ring segment sections 27 above and below the connecting line 6. This forms the magnetic field-sensitive component 1 with a continuous profile, whereby the magnetic field-sensitive component 1 has a greater distance to the connecting line 6 on its inner side 13 in the first passage area 4 and in the second passage area 4 than in the intermediate area 8. The minimum height 11 of the passage opening 2 in the intermediate area 8 is thus set by the magnetic field-sensitive component 1 approaching the connecting line 6 equally from both sides with its inner side 13.The gap 12 of the third embodiment is arranged centrally in the intermediate area 8 between the passage areas 4 and 5 and lies centrally on the connecting line 6. This means that the gap 12 is arranged symmetrically with respect to the connecting line 6.

[0218] The magnetic field-sensitive component 1 has a constant material thickness 15 around its circumference. The material thickness 15 is measured in a direction from the inside 13 of the magnetic field-sensitive component 1 to its outside 14, which, for example, in a region corresponding to the intermediate area 8, has a vertical extent 9. The material thickness 15 refers to the ring material belonging to the magnetic field-sensitive component 1. Page 48 / 64

[0219] P81039DE

[0220] In this exemplary embodiment, the minimum height extent 11 of the passage opening 2 in the intermediate area 8 lies in a range between 10% and 50% of the maximum height extent 10 of the first and second passage area 4, 5.

[0221] In this embodiment, the passage opening 2 has a passage opening width 19 in the width direction 7, and the intermediate area 8 has an intermediate area width 20 in the width direction 7, wherein the intermediate area width 20 in this embodiment is less than 60% of the passage opening width 19, but greater than 30% of the passage opening width 19.

[0222] The magnetic field-sensitive component 1 of the third embodiment is constructed from a layered soft magnetic material, as described above in relation to the magnetic field-sensitive component 1 of the first embodiment. The descriptions of the construction of the magnetic field-sensitive component 1 therefore apply accordingly. The same applies to the filtering effect of the magnetic field-sensitive component 1 with regard to the filtering of common-mode and differential-mode interference currents in through-hole electrical conductors.

[0223] The further explanations regarding the filtering effect of the first and second magnetic path 21, 22, as well as regarding the inductance and the magnetic properties, also apply accordingly, as described for the magnetic field-sensitive component 1 of the first embodiment.

[0224] Figure 4 shows a representation of a magnetic field-sensitive component 1 according to a fourth embodiment of the present invention.

[0225] The magnetic field-sensitive component 1 of the fourth embodiment largely corresponds to the magnetic field-sensitive component on page 49 / 64.

[0226] P81039DE

[0227] Component 1 of the second or third version is described in detail, so that identical features are not described again. Unless otherwise specified, the features of the magnetic field-sensitive component 1 of the fourth version correspond to those of the magnetic field-sensitive component 1 of the second or third version.

[0228] As can be seen in Figure 4, the magnetic field-sensitive component 1 is also flat and has a ring shape. Thus, the magnetic field-sensitive component 1 forms an internal opening 2 for the passage of at least one first and one second electrical conductor. The opening 2 extends through the magnetic field-sensitive component 1 in a direction 3. In this embodiment, the magnetic field-sensitive component 1 extends in the direction 3 over a length of approximately 35 mm.

[0229] The magnetic field-sensitive component 1 of the fourth embodiment comprises a soft magnetic material, which in this exemplary embodiment is designed as an amorphous soft magnetic material, in particular as metallic glass, and has a nanocrystalline structure. The soft magnetic material corresponds to that of the previously described embodiments.

[0230] As shown in Figure 4, the through-opening 2 comprises a first through-area 4 and a second through-area 5 for the passage of the first and second electrical conductors. A connecting line 6 between the first and second electrical conductors to be passed through, or between the centers of the first and second through-areas 4 and 5, defines a lateral direction 7 perpendicular to the passage direction 3. The two through-areas 4 and 5 are symmetrical with respect to a perpendicular bisector of the connecting line 6. Page 50 / 64

[0231] P81039DE

[0232] Here too, an intermediate area 8 remains between the passage areas 4 and 5, which is located along the connecting line 6 between the first passage area 4 and the second passage area 5.

[0233] The through-opening 2 has a height extent in a vertical direction 9 perpendicular to the horizontal direction 7 and the through-direction 3. The maximum height extent 10 of the through-opening 2 in the first through-area 4 and in the second through-area 4 is greater than the minimum height extent 11 of the through-opening 2 in the intermediate area 8, which is located between the two through-areas 4 and 5. The minimum height extent 11 of the through-opening 2 in the intermediate area 8 is greater than zero, so that a gap 12 remains in the intermediate area 8, i.e., a distance between opposing inner surfaces 13 of the magnetic field-sensitive component 1 in the intermediate area 8. The minimum height extent 11 thus defines a gap width of the remaining gap 12.The maximum height extension 10 of the passage opening 2 in the first passage area 4 and in the second passage area 5 is the same in this embodiment and is approximately 20 mm.

[0234] In the fourth embodiment, the magnetic field-sensitive component 1 is partially designed as a one-piece ring element, wherein the inner wall of the ring element defines an inner surface 13 of the magnetic field-sensitive component 1, and wherein an outer wall of the ring element defines an outer surface 14 of the magnetic field-sensitive component 1. This concerns two essentially semicircular sections 16, which limit the through-opening 2 in the width direction 7.

[0235] In Figure 4, both above and below the connecting line 6, the magnetic field-sensitive component 1 each has a two-part section 23, which essentially defines the two... Page 51 / 64

[0236] P81039DE connect the semicircular sections 16 above and below the connecting line 6 accordingly. In the two-part sections 23 corresponding to the intermediate area 8 in the width direction 7, the magnetic field-sensitive component 1 each has an inner and an outer ring element 24, 25, between which a recess 26 is formed. The inner ring element 24 and the outer ring element 25 each have the same extent in the through-direction 3.

[0237] Accordingly, the inner walls of the inner ring elements 24 form an inner surface 13 of the magnetic field-sensitive component 1, and the outer walls of the outer ring elements 25 form an outer surface 14 of the magnetic field-sensitive component 1. According to the fourth embodiment, the magnetic field-sensitive component 1 has an overall oval shape on its outer surface 14. The outer ring elements 25 thus have a greater distance to the connecting line 6 in a central region between the essentially semicircular sections 16 than in the transition region with the essentially semicircular sections 16, with the outer ring elements 25 being designed with a corresponding arc shape to form the oval shape.

[0238] The inner ring elements 24 of the magnetic field-sensitive component 1 have a profile such that the magnetic field-sensitive component 1 has a greater distance to the connecting line 6 on its inner side 13 in the first passage area 4 and in the second passage area 5 than in the intermediate area 8. The minimum height extent 11 of the passage opening 2 in the intermediate area 8 is thus set by the fact that the two inner ring elements 24, with their inner sides 13, approach the connecting line 6 equally from both sides. Page 52 / 64

[0239] P81039DE

[0240] As a result, the magnetic field-sensitive component 1 with the two-part section 23, which corresponds to the intermediate area 8 in the width direction 7, has an independent design on its inner side 13 and on its outer side 14.

[0241] The gap 12 of the fourth version is located in the intermediate area 8, centrally between the passage areas 4 and 5, and lies centrally on the connecting line 6. This means that the gap 12 is arranged symmetrically with respect to the connecting line 6.

[0242] The magnetic field-sensitive component 1 has a constant material thickness 15 around its circumference. The material thickness 15 is measured in a direction from the inner surface 13 of the magnetic field-sensitive component 1 to its outer surface 14, which, for example, in a region corresponding to the intermediate area 8, represents an extension in the vertical direction 9. The material thickness 15 refers to ring material belonging to the magnetic field-sensitive component 1, but not to any increase in the distance between the inner surface 13 and the outer surface 14 of the magnetic field-sensitive component 1 resulting from the recesses 26 between the inner ring element 24 and the outer ring element 25.

[0243] In this exemplary embodiment, the minimum height extent 11 of the passage opening 2 in the intermediate area 8 lies in a range between 10% and 50% of the maximum height extent of the first and second passage areas 4, 5.

[0244] In this embodiment, the passage opening 2 has a passage opening width 19 in the width direction 7, and the intermediate area 8 has an intermediate area width 20 in the width direction 7, wherein the intermediate area width 20 in this embodiment is less than 60% of page 53 / 64

[0245] P81039DE

[0246] Passage opening width 19, but greater than 30% of the passage opening width 19.

[0247] The magnetic field-sensitive component 1 of the fourth embodiment is constructed from a layered soft magnetic material, as described above with reference to the magnetic field-sensitive component 1 of the first embodiment. The descriptions of the construction of the magnetic field-sensitive component 1 therefore apply accordingly. The same applies to the filtering effect of the magnetic field-sensitive component 1 with regard to the filtering of common-mode interference currents of the first embodiment as well as differential-mode interference currents in through-hole electrical conductors. The circumferential first magnetic path 21 includes both the inner ring element 24 and the outer ring element 25. The second magnetic path 22 includes the gap 12 in the intermediate region 8, in which the minimum height extent 11 of the through-hole 2 is smaller than the maximum height extent 10 of the through-hole 2 in the first through-hole 4 and in the second through-hole 5.Of the two-part sections 23, the inner ring elements 24 in particular contribute to the second magnetic path 22. The further explanations regarding the filtering effect of the first and second magnetic paths 21 and 22, as well as the inductance and magnetic properties, apply accordingly as for the magnetic field-sensitive component 1 of the second or third embodiment.

[0248] For each of the first to fourth embodiments, a magnetic field-sensitive assembly can be formed starting from the corresponding magnetic field-sensitive component 1, which includes the corresponding magnetic field-sensitive component 1. Additionally, the magnetic field-sensitive assembly has an insulating housing in which the magnetic field-sensitive component 1 is accommodated. Page 54 / 64

[0249] P81039DE

[0250] The insulating housing completely encloses the magnetic field-sensitive component 1, i.e., the insulating housing surrounds the magnetic field-sensitive component 1 along the inner side 13, the outer side 14, and along connecting sides 29, either completely or with cutouts. The first and second passage areas 4, 5 in the insulating housing are provided for the passage of the first and second electrical conductors.

[0251] The insulating housing consists of a plastic, in particular a thermoplastic and / or a thermosetting plastic.

[0252] In one embodiment, the insulating housing is designed as a coating on the magnetic field-sensitive component 1. The magnetic field-sensitive component 1 can, for example, be immersed in a liquid plastic material, so that this adheres to the magnetic field-sensitive component 1 and solidifies on it, forming the insulating housing after solidification.

[0253] In an alternative embodiment, the insulating housing is designed as a separate housing, and the magnetic field-sensitive component 1 is enclosed within the housing. The insulating housing is designed in two parts, consisting of a housing shell and a housing cover. The insulating housing is manufactured from a thermoplastic and / or a thermoset using an injection molding process and / or a thermoforming process and / or a PUR-RIM process and / or another plastic manufacturing process.

[0254] The magnetic field-sensitive assembly, together with at least one first and one second electrical conductor, forms an inductive assembly. In the inductive assembly, the first electrical conductor passes at least once through the first passage area 4, and the second electrical conductor (page 55 / 64)

[0255] P81039DE has passed through the second passage area 5 at least once.

[0256] Once the first and / or second electrical conductor has passed through the corresponding passage area 4, 5, it can, in principle, be positioned arbitrarily within it, for example, in the center. Alternatively, the first and / or second electrical conductor is positioned in an edge region of the passage area 4, 5, i.e., adjacent to the magnetic field-sensitive component 1. If the first and / or second electrical conductor has passed through the corresponding passage area 4, 5 multiple times, the second electrical conductor is typically positioned in an edge region of the passage area 4, 5, i.e., adjacent to the magnetic field-sensitive component 1. In this case, the electrical conductor is preferably tightly wound around the magnetic field-sensitive component 1 within the corresponding passage area 4, 5.

[0257] The magnetic field-sensitive assembly described above can be used as an inductive component for reducing common-mode and / or differential-mode interference for the first and second electrical conductors in the state correspondingly guided through the first passage 4 and the second passage 5. Advantageously, the magnetic field-sensitive assembly can be used as an inductive component or inductive assembly in a power supply system, preferably in a DC power supply system and particularly preferably in a DC power supply system for powering a battery-electric storage device.

[0258] The power supply system can be designed as a charger, in particular as a charger for a vehicle, having a page 56 / 64

[0259] P81039DE battery-electric storage device, preferably for a battery-electric vehicle (BEV), and more preferably for a battery-electric commercial vehicle. Alternatively, the power supply system, in particular as a DC power supply system, can be configured to supply an electrical consumer with current, in particular an electric drive unit, preferably an electric motor, in particular an electric motor of a vehicle, most preferably from a battery-electric storage device.

[0260] The power supply system can include at least one frequency converter.
