[0025] When an element or layer is described as being "on" or "interacting with" another element or layer, or as being "connected" or "coupled" or "attached" to the same, it may be directly on or interacting with, connected with, coupled to, or attached to the other element or layer, or there may be intervening elements or layers. However, when an element is described as being "directly on" or "directly interacting with" another element or layer, or as being "directly connected" or "directly coupled" or "directly attached" to the same, there must be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted similarly (e.g.,B. “between” as opposed to “directly between”, “neighboring” or “adjacent” as opposed to “directly adjacent” or “directly bordering”, etc.). The term “and / or” as used herein encompasses all combinations of one or more of the related listed points.

[0026] The terms “first,” “second,” “third,” etc., may be used herein to describe different elements, components, areas, layers, and / or sections. These elements, components, areas, layers, and / or sections should not be restricted by these terms. These terms may only be used to distinguish one element, component, area, layer, or section from another. Unless explicitly stated by the context, terms such as “first,” “second,” and other numerical terms do not imply any particular sequence or order.Thus, one could refer to a first element, a first component, a first area, a first layer or a first section, which are discussed below, as a second element, second component, second area, second layer or second section, without deviating from the principles of the exemplary designs.

[0031] Non-transient memory can be physical devices used for the temporary or permanent storage of programs (e.g., sequences of instructions) or data (e.g., program status information) for use by a computer. Non-transient memory can be volatile and / or non-volatile addressable semiconductor memory.

[0035] To enable interaction with a user, one or more aspects of the revelation can be implemented on a computer that has a display device, such as a CRT or LCD monitor or a touchscreen, to show information to the user, and optionally a keyboard and pointing device, such as a mouse or trackball, with which the user can input information into the computer. Other types of devices can also be used to enable interaction with the user; for example, the user can receive any form of sensory feedback, such as visual, auditory, or tactile feedback, and user input can be received in any form, including acoustic, verbal, or tactile input. Furthermore, a computer can interact with a user by sending and receiving documents to and from a device used by the user, such as...by sending web pages to a web browser on a user's client device after requests have been received from the web browser.

[0036] In general, battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), hybrid electric vehicles (HEVs), and fuel cell electric vehicles (xEVs) can be affected by electromagnetic interference (EMI). For example, EMI can disrupt the operation of vehicle electronics and / or violate EMI regulations. EMI is a process by which electromagnetic energy is transferred from one electrical device to another via radiation and / or conduction. Types of EMI include radiated EMI, common-mode EMI, and differential EMI.

[0037] EMI emissions originate from an emitting source and propagate along a radiation path until they reach a sensitive receiver. The intensity of the radiated EMI can depend on the source, the device, and the sensitive receiver.

[0038] Common-mode EMI can be electrically generated when a circuit with a high voltage rise rate (i.e., dV / dt) has significant parasitic capacitance to ground. In other words, common-mode EMI appears as an unwanted current measured across one or more conductors connected in parallel to a common reference ground.

[0039] Differential EMI can be a signal that appears on two lines of a closed control loop where the current flows in opposite directions. This generally occurs in series with a desired signal.

[0040] Existing chokes typically rely on expensive materials to handle one or more types of EMI and / or filter noise currents. According to the principles of this disclosure, a choke is provided to reduce costs, reduce weight, improve thermal conductivity, and / or improve inductance for a target frequency.

[0041] With reference to Fig. Figure 1 provides an illustrative example of a vehicle 10 with a vehicle body 12. The vehicle 10 includes one or more wheels 14 coupled to the vehicle body 12. Furthermore, the vehicle 10 includes a drive system 100 that supplies energy to at least one of the wheels 14 in order to propel the vehicle 10.

[0042] In general, the drive system 100 comprises a power source (e.g., a battery) 110, an inverter 120, and an electric motor (i.e., a motor) 130. The inverter 120 includes an input coupled to the battery 110 and an output coupled to the motor 130.

[0043] In a configuration such as in Fig. As shown in Figure 2A, the drive system 100 also includes an inductor 200, which is communicatively coupled to and located between the battery 110 and the input of the inverter 120. Positioning the inductor 200 between the battery 110 and the inverter 120 may be desirable to reduce EMI emanating from or received by other systems connected to the battery.

[0044] In a further embodiment, as in Fig. As shown in Figure 2B, the drive system 100' includes the choke 200, which is communicatively coupled to the output of the inverter 120 and the motor 130 and is located between them. The arrangement of the choke 200 between the inverter 120 and the motor 130 may be desirable to reduce EMI, common-mode current, and bearing current.

[0045] In yet another variation, as in Fig. As shown in Figure 2C, the 100" drive system includes the throttle 200, which is communicatively coupled to and located within the motor 130. Positioning the throttle 200 inside the motor 130 may be desirable to reduce the packaging size and overall weight and to increase the power density.

[0046] With reference to Fig. Figure 3 describes a choke 300 comprising two or more materials arranged circumferentially to improve and / or target its electrical, thermal, and / or mechanical properties. For example, the choke 300 may be configured to filter noise currents, reduce electromagnetic interference, improve thermal conductivity, and / or reduce vibrations. The choke 300 comprises a first end 302 and a second end 304 spaced apart from the first end 302. The choke 300 includes one or more first segments 306 and one or more second segments 308 coupled to the first segments 306. The one or more first segments 306 and the one or more second segments 308 may be arranged to define a perimeter extending between the first end 302 and the second end 304.Furthermore, the one or more first segments 306 and the one or more second segments 308 can be arranged to define an opening 310 extending between the first end 302 and the second end 304. The opening 310 can be configured to receive one or more wires or cables 311 extending between the first end 302 and the second end 304. In the present illustrative example, the one or more first segments 306 comprise end caps 312 having one or more connecting surfaces 314. The one or more second segments 308 can comprise plates 316 having one or more end surfaces 318 that correspond to and are configured to connect to the one or more connecting surfaces of the end caps 312.

[0047] According to one aspect, the one or more first segments 306 can consist of a first material and the one or more second segments 308 of a second material that differs from the first material. In at least one example, the first material and the second material are nanocrystalline but exhibit different electrical, thermal, and / or mechanical properties. In an embodiment such as in Fig. As shown in Figure 3, one or more first segments 306 can be made of material A (e.g., FT-3K50T) and one or more second segments 308 can be made of material B (e.g., FT-3KM). In a further embodiment, as shown in Fig. As shown in Figure 4, the choke 300' can be arranged such that the one or more first segments 306 are made of material B and the one or more second segments 308 are made of material A. Other materials can also be chosen for the one or more first segments 306 and / or the one or more second segments 308, such as other nanocrystalline materials, ferrite materials, magnetic materials, heat-insulating materials, thermally conductive materials, electrically insulating materials, or other materials commonly used to manage unwanted NVH (noise, vibration, and harshness). Additionally or alternatively, a material with low magnetic permeability can be arranged in a region of the choke 300 with a high electromagnetic field, and a material with high permeability can be arranged in a region of the choke 300 with a low electromagnetic field, or vice versa.

[0048] With reference to Fig. Figure 5 shows a diagram illustrating the relationship between frequency (MHz) and inductance (µH) for two chokes made of one material and for chokes 300 and 300', which consist of more than one material. In the low-frequency range, choke 300 achieves a similar inductance to a single-material choke made of material A, which helps reduce bearing current, while in the medium and high-frequency ranges, lower inductance is required to reduce choke losses. In choke 300', 40% of the total volume was replaced by material B, which is less expensive than material A.

[0049] Fig. Figure 6 shows another exemplary embodiment of a 400-series throttle. This embodiment is similar in many respects to the embodiment shown in Figure 6. Fig. 3-5. Accordingly, the descriptions of the designs are hereby mutually included, and the description of objects that the designs have in common is generally not repeated.

[0050] With reference to Fig. Figure 6 describes the choke 400, which comprises two or more materials arranged circumferentially to improve and / or target electrical, thermal, and / or mechanical properties. The choke 400 can, for example, be configured to filter noise currents, reduce electromagnetic interference, improve thermal conductivity, and / or reduce vibrations. The choke 400 comprises one or more first segments 402 and one or more second segments 404 coupled to the first segments 402. The one or more first segments 402 can be coupled to the one or more second segments 404 by welding (e.g., spot welding, laser welding, etc.), brazing, bonding, or any other technique commonly used in the automotive industry, or otherwise attached.The one or more first segments 402 and the one or more second segments 404 can be arranged to form a perimeter 406. In the present example, the perimeter 406 is rectangular, but other examples may have a circular, square, oval, or other perimeter shape 406. Furthermore, the one or more first segments 402 and the one or more second segments 404 can be arranged to define an opening 408 configured to receive one or more wires or cables (not shown).

[0051] According to one aspect, the one or more first segments 402 can have a slot 410 designed to receive an insert 412. Likewise, the one or more second segments 404 can have a slot 414 designed to receive an insert 416. The one or more first segments can be made of a first material, the one or more second segments can be made of a second material, and the inserts 412 and 416 can be made of a third material. According to another aspect, the inserts 412 for the one or more first segments 402 can be made of the third material, and the inserts 416 for the one or more second segments 404 can be made of a fourth material, different from the third. The inserts 412 and 416 may be desirable for improving the thermal management (e.g., heat dissipation) of the throttle 400.For example, for inserts 412, 416, which are located in areas of the throttle 400 that have a high heat loss, a material with a low thermal resistance (R) can be selected.

[0052] The inserts 412, 416 can be arranged in the slots 410 and 414, respectively, such that there are no air gaps between the inserts 412, 416 and the one or more first and second segments 402, 404. The absence of an air gap may be desirable, for example, to increase the inductance of the choke 400. In another example, one of the inserts 412, 416 can be arranged with respect to the one or more first and second segments 402, 404 such that air gaps are present (not shown). Including the air gap may be desirable, for example, to increase the saturation limit in a region of the choke 400. Finally, more than one of the chokes 400 can be stacked, fastened, coupled, and / or arranged side by side, so that, for example, multiple openings for multiple wires and / or cables are present.

[0053] Fig. Figure 7 shows another exemplary embodiment of a 500-series throttle. This embodiment is similar in many respects to the embodiment shown in Figure 7. Fig. 3-5 and Fig. 6. Accordingly, the descriptions of the designs are hereby mutually included, and the description of objects that the designs have in common will generally not be repeated.

[0054] With reference to Fig. 7 The throttle 500 comprises a first segment or first half 502 and a second segment or second half 504. The first half 502 can generally have an inner surface 506 and an outer surface 508 spaced apart from the inner surface 506. The first half 502 can also have end surfaces 510 extending between the inner surface 506 and the outer surface 508. The second half 504 can generally have an inner surface 512 and an outer surface 514 spaced apart from the inner surface 512. The second half 504 can also have end surfaces 516 extending between the inner surface 512 and the outer surface 514. In the present illustrative example, the end surfaces 510, 516 of the first and second halves 502, 504 are designed to interlock, such that an opening 518 is defined by the inner surface 506 of the first half 502 and the inner surface 512 of the second half 504. Although in Fig. Although not immediately apparent, the throttle 500 may have a hinge so that the first half 502 can open and close in relation to the second half 504 (clamshell design).

[0055] According to one aspect, the first half 502 can be made of a first material and the second half 504 of a second material that differs from the first material. For example, the first half 502 can be made of a material with high thermal conductivity. Thus, according to at least one example, a cooling plate or a cooling housing 520 can be arranged on part of the inner and / or outer surfaces 512, 514, for example, to dissipate heat from the second half 504 during operation.

[0056] Fig. Figures 8-10 show exemplary configurations of a 600, 600' throttle. These configurations are similar in many respects to the configurations from Fig. 3-5, Fig. 6 and Fig. 7. Accordingly, the descriptions of the designs are hereby mutually included, and the description of objects that the designs have in common will generally not be repeated.

[0057] With reference to Fig. Figure 8 shows the throttle 600, which comprises one or more first segments 602 and one or more second segments 604. The one or more first segments 602 can be arranged to form a circumference 606. Furthermore, the one or more first segments 602 can be arranged to define an opening 608 that is radially inwardly spaced from the circumference 606. Each of the one or more first segments 602 includes a through-hole 610 extending between a first end 612 and a second end (not shown) that projects into the side. As shown in Fig. As shown in Figure 8, one or more second segments 604 are arranged in the through-holes 610. In the present example, the through-holes 610 are rectangular and the second segments 604 are also rectangular. In another embodiment, the through-holes 610 and the second segments 604 are oval or triangular. In a further embodiment of the throttle 600', as shown in Fig. As shown in Figure 9, some of the through-holes 610 have a first (e.g., oval) shape 610a and a second (e.g., rectangular) shape 610b. Similarly, some of the one or more second segments 604 may have a first (e.g., oval) shape 604a and are configured to correspond with the through-holes 610 that have the first shape 610a. Likewise, some of the one or more second segments 604 may have a second (e.g., rectangular) shape 604b and are configured to correspond with the through-holes 610 that have the second shape 610b. In one aspect, more than one of the chokes 600, 600' can be stacked, fastened, coupled, and / or arranged side by side, so that, for example, multiple openings are provided for multiple wires and / or cables.

[0058] Fig. Figure 10 shows an exemplary design of a Drossel 700. These designs are similar in many respects to the designs from Fig. 3-5, Fig. 6, Fig. 7 and Fig. 8-9. Accordingly, the descriptions of the designs are hereby mutually included, and the description of objects that the designs have in common is generally not repeated.

[0059] With reference to Fig. Figure 10 shows a unit cell of the throttle 700. The throttle 700 comprises a first segment 702 and one or more second segments 704. The first segment 702 comprises a circumference 706 and an opening 708 spaced radially inward from the circumference 706. The first segment 702 includes one or more through-holes 712, each extending between a first end 714 and a second end (not shown) projecting into the side.
