AI Technical Summary
Existing automotive controller filtering solutions are costly and prone to causing EMC performance degradation. In plastic-coated filtering solutions, the coupling between the capacitor and the main copper busbar leads to EMC performance degradation. In PCB filtering solutions, the cost of soldering materials is high and the extended current path generates redundant equivalent series inductance.
An integrated capacitor module combining X and Y capacitor units is adopted. The X capacitor unit is located between two adjacent Y capacitor units, and its leads are bent to form an extension perpendicular to the current direction of the copper busbar. Combined with an iron-based nanocrystalline inductor module, the layout of the capacitor module in the filter device is optimized.
This reduces the space occupied by the capacitor module in the filter device, improves electromagnetic compatibility performance, reduces production costs, and ensures the consistency of the equivalent series inductance and EMC performance.

[0002] The filter scheme of the prior art automobile controller mainly has two kinds, which are plastic-wrapped filter scheme and PCB filter scheme.
[0003] In the plastic-wrapped filter scheme, on the one hand, some capacitors are arranged in parallel with the main copper bar, causing the coupling of the current magnetic field of the main copper bar and the current magnetic field of the capacitors, resulting in the degradation of EMC (electromagnetic compatibility) performance; on the second hand, the capacitors and the main copper bar and the grounding copper bar all adopt the clamp welding method of capacitor pins and copper bar pins, and the excess equivalent series inductance is generated in the unnecessary current path of the capacitor pins and the copper bar pins, resulting in the degradation of EMC performance; on the third hand, due to the inconsistency of the copper bar and the expansion coefficient of the wrapped plastic, the wrapped plastic is prone to cracking in temperature cycling, reducing the product reliability.
[0004] In the PCB filter scheme, on the one hand, the capacitor pins and the PCB board need to adopt selective welding process, in order to ensure the welding reliability, the welding material must be selected from special solder, which requires maintaining the temperature of the soldering furnace equipment and cannot be cooled, and the maintenance cost is high, which increases the production cost of the overall filter scheme; on the second hand, the current path of the capacitors and the main copper bar needs to pass through the PCB board and the adapter copper bar, and the ground current of the capacitors also needs to flow through the PCB, which prolongs the current path and generates excess equivalent series inductance, resulting in the degradation of EMC performance; on the third hand, a support plastic piece is arranged between the PCB board and the main copper bar, which makes the filter assembly process complex and increases the production cost.

Referring to Figure 1 The present application provides a capacitor module 10, which includes at least one X capacitor unit and at least one Y capacitor unit, and the X capacitor unit and the Y capacitor unit are arranged along a reference direction A, i.e. the X capacitor unit and the Y capacitor unit are arranged in a linear shape. For example, Figure 1 The X capacitor unit is located between two Y capacitor units. Of course, when the number of X capacitor units and Y capacitor units is multiple, the multiple X capacitor units and the multiple Y capacitor units are arranged in sequence along the reference direction, and the X capacitor unit can be arranged between adjacent Y capacitor units, or the multiple X capacitor units are arranged in sequence adjacent to one side, and the multiple Y capacitor units are arranged in sequence adjacent to the other side. The X capacitor unit includes at least one X capacitor core 11, and the Y capacitor unit includes at least one Y capacitor core 12. For example, referring to Figure 1The X capacitor unit demonstrated by the embodiment comprises a single X capacitor core 11, the Y capacitor unit comprises a single Y capacitor core 12, and two Y capacitor cores 12 are arranged on the two sides of the X capacitor core 11 respectively. The X capacitor core 11 and the Y capacitor core 12 are integrated together to realize the integrated capacitor module 10, so that the space of the capacitor module 10 can be greatly reduced, and the design cost can be saved.
[0047] Further, when the X capacitor unit comprises at least two X capacitor cores 11, the at least two X capacitor cores 11 are connected in series or in parallel, that is, the at least two X capacitor cores 11 are arranged in series along the reference direction A or are arranged in parallel along the direction perpendicular to the reference direction A.

Further, the capacitor module 10 further comprises a capacitor base shell 16, the X capacitor unit and the Y capacitor unit are accommodated in the capacitor base shell 16, one side of the capacitor base shell 16 is open, the inside of the capacitor base shell 16 can be handled by pouring glue through the opening of the capacitor base shell 16, so that the X capacitor core 11 and the Y capacitor core 12 in the capacitor base shell 16 are encapsulated, insulated and fixed.
[0049] Figure 3is a schematic diagram of the filter device of one embodiment of the present application. The present application schematically provides a filter device, which comprises a copper bar group 30, at least one inductance module 20 and at least one capacitance module. The capacitance module here is the capacitance module 10 as described above, and the number of Y capacitor units in the capacitance module 10 is at least two. The copper bar group 30 comprises two copper bars arranged in the same plane and side by side, one of which is a positive copper bar and the other is a negative copper bar. The inductance module 20 and the capacitance module 10 are arranged along the parallel direction of the copper bar group 30, and the capacitance module 10 and the inductance module 20 are connected between the positive copper bar and the negative copper bar. Specifically, for the capacitance module 10, the arrangement direction (the reference direction A) of the X capacitor unit and the Y capacitor unit in the capacitance module 10 is parallel to the plane of the copper bar and perpendicular to the parallel direction of the copper bar group 30, the X capacitor unit is connected between the positive copper bar and the negative copper bar, at least one Y capacitor unit is connected between the positive copper bar and the reference ground, and at least another Y capacitor unit is connected between the negative copper bar and the reference ground. The filter device can be applied to an automobile controller, and the reference ground here can be the external shell of the automobile controller. It should be noted that for the capacitance module 10 applied to the filter device, the arrangement of at least two Y capacitor units and at least one X capacitor unit in the capacitance module 10 is not limited, such as arranging X capacitor units between two adjacent Y capacitor units, or arranging Y capacitor units adjacent to one side of X capacitor units.
[0050] Thus, the capacitance module 10 of the present embodiment is applied to the filter device, and based on the layout design of the capacitance module 10, the space occupied by the capacitance module 10 in the filter device can be reduced. Moreover, the X capacitor core 11 and the Y capacitor core 12 are arranged along the reference direction A, that is, collinearly arranged. When the capacitance module 10 is applied to the filter device, the arrangement direction of the X capacitor core 11 and the Y capacitor core 12 can be perpendicular to the parallel direction of the copper bar group 30 in the filter device, so that the arrangement of the X capacitor core 11 and the Y capacitor core 12 in the capacitance module 10 is perpendicular to the current direction on the copper bar group 30. In this way, the layout of the capacitance module 10 can not only improve the electromagnetic compatibility of the filter device, but also reduce the space occupied by the copper bar group 30 in the parallel direction thereof. Preferably, X capacitor units are arranged between two adjacent Y capacitor units, so that the two Y capacitor units are symmetrically arranged on both sides of the X capacitor units, which not only ensures the ESL (equivalent series inductance) performance between the positive copper bar and the negative copper bar, the ESL performance of the positive copper bar to the reference ground and the ESL performance of the negative copper bar to the reference ground, but also makes the ESL performance of the positive copper bar to the reference ground and the ESL performance of the negative copper bar to the reference ground consistent.
[0051] Optionally, the filter device comprises at least two capacitor modules 10, and an inductor module 20 is arranged between two adjacent capacitor modules 10. In this way, the corresponding capacitor modules 10 and inductor modules 20 can be configured according to the actual filtering requirements of the scene, thereby improving the applicability and platform compatibility of the filter device. It should be noted that the number of capacitor modules 10 and inductor modules 20 and the arrangement manner need to meet that the two sides are capacitor modules 10, for example, two capacitor modules 10 and one inductor module 20 are configured as a CLC three-stage filter device, and three capacitor modules 10 and two inductor modules 20 form a CLCLC five-stage filter device.
[0052] Preferably, the inductor module 20 comprises a Fe-based nanocrystalline inductor. The main body of the inductor module 20 is made of a Fe-based nanocrystalline alloy, which has higher performance than a traditional ferrite powder core in a unit volume, that is, a volume advantage is obtained under a certain performance premise, thereby greatly reducing the filtering volume and improving the flexibility of overall arrangement of the filter device. Further, the inductor module 20 further comprises an inductor protective shell, the Fe-based nanocrystalline inductor is contained in the inductor protective shell, and the inductor protective shell is provided with a fixing seat 21 on both sides along the parallel reference direction A, and the fixing seat 21 can be fixed to the external shell of the automobile controller, for example, the fixing seat 21 is connected to the automobile controller through bolts.
[0053] Figure 4 is a schematic view of a protective shell of the filter device of an embodiment of the utility model. Referring to Figure 4 Optionally, the filter device comprises a protective shell 40, the capacitor modules 10 and the inductor modules 20 are contained in the protective shell 40, and the copper bar group 30 passes through the protective shell 40. The design of the protective shell can avoid that particulate matter enters the capacitor modules 10 and the inductor modules 20, and the capacitor modules 10 and the inductor modules 20 are protected from collision. In an embodiment, the protective shell 40 comprises an upper base shell 41 and a lower base shell 42 that can be assembled with each other, facilitating disassembly and replacement of the capacitor modules 10 and the inductor modules 20.
[0054] For the manner that the X capacitor unit is connected between the positive copper bar and the negative copper bar, the manner that at least one Y capacitor unit is connected between the positive copper bar and the reference ground, and the manner that at least another Y capacitor unit is connected between the negative copper bar and the reference ground, refer to Figure 1The capacitor module is demonstrated to have X capacitor units symmetrically arranged with Y capacitor units on both sides of the X capacitor units, and the first pin 13 is led out from the side of the X capacitor unit along the reference direction A close to the Y capacitor unit. It should be noted that the X capacitor unit is symmetrically arranged with Y capacitor units on both sides, and here it means that the X capacitor unit leads out one first pin 13 on each side. The Y capacitor unit on each side leads out one second pin 14 from the side of the Y capacitor unit along the reference direction A close to the X capacitor unit, and leads out one ground pin 15 from the side of the Y capacitor unit along the reference direction A away from the X capacitor unit. The first pin 13 is connected with the X capacitor core 11, and when there are at least two X capacitor cores 11 in the X capacitor unit, all the X capacitor cores 11 are connected with the first pin 13. The first pin 13 on each side of the X capacitor unit is connected to the positive copper bar and the negative copper bar respectively, so as to connect the X capacitor unit between the positive copper bar and the negative copper bar. The second pin 14 and the ground pin 15 are both connected with the corresponding Y capacitor core 12, and when there are at least two Y capacitor cores 12 in the Y capacitor unit, all the Y capacitor cores 12 in the Y capacitor unit are connected with the second pin 14, and all the Y capacitor cores 12 are connected with the ground pin 15. The second pin 14 of one Y capacitor unit is connected to the positive copper bar, and the second pin 14 of the other Y capacitor unit is connected to the negative copper bar, and the ground pin 15 is used to connect to the reference ground, such as connecting the external shell of the automobile controller. In the actual product, the ground pin 15 extends out of the protective shell 40 in the filter device, so as to connect to the reference ground. For example, a bolt connection hole is formed on the ground pin 15, and the ground pin 15 is fixed and connected to the reference ground through the bolt.
[0055] Further, the capacitor module 10 has a reference end face parallel to the reference direction A, and the first pin 13, the second pin 14 and the ground pin 15 extend on the same side of the reference end face. The reference end face here can be the reference end face of the parallel copper bar group 30 in the capacitor module 10, which is only used for position reference. For example, the reference end face here can be the reference end face defined at the opening of the capacitor base shell 16, and the first pin 13, the second pin 14 and the ground pin 15 all extend out of the capacitor base shell 16 through the opening of the capacitor base shell 16, so that the first pin 13, the second pin 14 and the ground pin 15 are all located on the same side of the opening of the capacitor base shell 16, which ensures that in the assembly process, the first pin 13 and the second pin 14 are easily welded to the copper bar group 30, and the operation of connecting the pins to the reference ground is facilitated.
[0056] Preferably, the first pin 13, the second pin 14 and the ground pin 15 are all plate-shaped. The first pin 13 is bent to form a first extension 130, the first extension 130 extends along the reference direction A and is parallel to the reference end face, that is, the first pin 13 is bent by 90° to form the first extension 130, and the first extension 130 is used to lap on the copper bar group 30. The second pin 14 is bent to form a second extension 140, the second extension 140 extends along the reference direction A and is parallel to the reference end face, that is, the second pin 14 is bent by 90° to form the second extension 140, and the second extension 140 laps on the copper bar group 30. The ground pin 15 is bent to form a third extension 150, the third extension 150 extends along the reference direction A and is parallel to the reference end face, that is, the ground pin 15 is bent by 90° to form the third extension 150, and the third extension 150 laps on the reference ground. In this way, the first extension 130 and the second extension 140 formed by the bending process lap on the surface of the copper bar group 30, which can realize the welding of the first pin 13 and the second pin 14 with the copper bar group 30 on one side of the copper bar group 30, simplify the welding operation, reduce the welding tooling, and reduce the production cost. Moreover, the first extension 130 and the second extension 140 formed by the bending process can offset certain assembly errors between the first pin 13 and the second pin 14 and the copper bar, and the third extension 150 formed by the bending process can also offset certain assembly errors of the ground pin 15 to the reference ground, thereby improving the overall reliability of the filter device. In this way, the first pin 13 and the second pin 14 can lap on the copper bar at the shortest distance after the bending process of the first pin 13, the second pin 14 and the ground pin 15, and the ground pin 15 is connected to the reference ground at the shortest distance, which ensures that the distance between the X capacitor unit and the Y capacitor unit connected to the copper bar group 30 is the shortest, and the distance between the Y capacitor unit and the reference ground is the shortest, thereby greatly improving the ESL performance of the capacitor module 10.
[0057] It should be noted that, taking the example that the X capacitor unit is arranged between two adjacent Y capacitor units, the embodiment does not limit the bending direction of the first pin 13 on both sides of the X capacitor unit, does not limit the bending direction of the second pin 14 corresponding to each of the two Y capacitor units, and does not limit the bending direction of the ground pin 15 corresponding to each of the Y capacitor units. For example, when the first pin 13 is bent to form the first extension 130, the two first pins 13 are bent away from each other, bent towards each other, or bent in the same direction along the reference direction A, and when the first pin 13 is bent towards the X capacitor unit, at least a part of the vertical projection of the first extension 130 is within the range of the X capacitor unit, and when the first pin 13 is bent towards the Y capacitor unit, at least a part of the vertical projection of the first extension 130 is within the range of the Y capacitor unit. The two second pins 14 are bent away from each other, bent towards each other, or bent in the same direction along the reference direction A, and when the second pin 14 is bent towards the X capacitor unit, at least a part of the vertical projection of the second extension 140 is within the range of the X capacitor unit, and when the second pin 14 is bent towards the Y capacitor unit, at least a part of the vertical projection of the second extension 140 is within the range of the Y capacitor unit. When the ground pin 15 is bent to form the third extension 150, the two ground pins 15 are bent away from each other along the reference direction A, and the third extension 150 extends out of the Y capacitor unit along the reference direction A.
