[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Reference below Figure 1-Figure 9 The inductor assembly 100 and the power generation device according to the embodiment of the utility model are described. The power generation device may be a new energy power generation device such as an inverter. The present application takes the power generation device as an inverter as an example for description.

[0037] According to the inductor assembly 100 of the embodiment of the present utility model, Figure 1-Figure 5 As shown, the inductor component 100 includes: a common-mode core 10, the common-mode core 10 has a first assembly hole 11; a plurality of differential-mode cores 20, each of which has a second assembly hole 21; a plurality of annular windings 30, the plurality of annular windings 30 and the plurality of differential-mode cores 20 are assembled in a one-to-one correspondence, each annular winding 30 passes through the first assembly hole 11 and the corresponding second assembly hole 21, so that each annular winding 30 is wound around the common-mode core 10 and the corresponding differential-mode core 20, and the axial directions of the plurality of annular windings 30 are parallel to each other.

[0038] Among them, the inductor component 100 may include: a common-mode core 10, a plurality of differential-mode cores 20 and a plurality of annular windings 30, for example: the common-mode core 10 may be made of materials such as ferrite and nanocrystalline ribbon, and the differential-mode core 20 may be made of materials such as magnetic powder core, silicon steel sheet, ferrite, etc. This application is described by taking the annular winding 30 made of copper wire as an example, but the utility model is not limited to this, and the common-mode core 10 and the differential-mode core 20 may also be made of other materials respectively, as long as the common-mode core 10 and the differential-mode core 20 can play an anti-interference role. Specifically, the plurality of differential-mode cores 20 may all be the same runway-shaped differential-mode cores 20 with equal long sides, and the shapes and sizes of the plurality of annular windings 30 may also be the same.

[0039] The common mode core 10 may have a first assembly hole 11, which may penetrate the common mode core 10 along the thickness direction of the common mode core 10, so that the annular winding 30 passes through the first assembly hole 11. Each differential mode core 20 has a second assembly hole 21, which may penetrate the differential mode core 20 along the thickness direction of the differential mode core 20, so that the annular winding 30 passes through the second assembly hole 21.

[0040] Multiple annular windings 30 and multiple differential-mode cores 20 are assembled in a one-to-one correspondence. For example, the number of annular windings 30 can be three, four, five, six, etc., and the number of differential-mode cores 20 can be three, four, five, six, etc., but the utility model is not limited thereto. The number of annular windings 30 and the number of differential-mode cores 20 can also be other numbers, as long as there are multiple annular windings 30 and differential-mode cores 20. Specifically, the number of annular windings 30 can be the same as the number of differential-mode cores 20, so that multiple annular windings 30 and multiple differential-mode cores 20 are assembled in a one-to-one correspondence. This application is explained by taking multiple annular windings 30 passing through the second assembly holes 21 of the corresponding differential-mode cores 20 for assembly as an example.

[0041] Each annular winding 30 passes through the first assembly hole 11 and the corresponding second assembly hole 21, so that each annular winding 30 is wound around the common-mode magnetic core 10 and the corresponding differential-mode magnetic core 20. The annular winding 30 and the common-mode magnetic core 10 constitute a common-mode inductor, and the annular winding 30 and the differential-mode magnetic core 20 constitute a differential-mode inductor. Such an arrangement enables the common-mode magnetic core 10 and the differential-mode magnetic core 20 to share the annular winding 30, which can reduce the board area of ​​the inductor component 100, thereby saving the overall space of the power generation device, and under the same temperature rise, the cross-sectional area of ​​the annular winding 30 can be reduced, further reducing the manufacturing cost of the power generation device, and can also improve the overall efficiency of the power generation device.

[0042] The axial directions of the multiple annular windings 30 are parallel to each other, so that the partitions separating the multiple annular windings 30 can be eliminated, thereby simplifying the component composition of the inductor assembly 100 and reducing the manufacturing cost of the inductor assembly 100. Figure 1 and Figure 2 As shown, along the X direction, the winding directions of the multiple annular windings 30 are consistent, so that the cold wind can penetrate the multiple annular windings 30 in sequence without shielding for air cooling and heat dissipation. Figure 2 In the middle Y direction, the two rows of differential-mode cores 20 can be staggered so that the two rows of differential-mode cores 20 will not block the corresponding annular windings 30 from each other, thereby facilitating cold air to penetrate the multiple annular windings 30 in sequence without obstruction for air cooling and heat dissipation, thereby improving the air cooling and heat dissipation effect of the inductor component 100.

[0043] According to the inductor assembly 100 of the embodiment of the utility model, by arranging multiple annular windings 30 and multiple differential-mode magnetic cores 20 for one-to-one matching assembly, each annular winding 30 passes through the first assembly hole 11 and the corresponding second assembly hole 21, so that each annular winding 30 is wound around the common-mode magnetic core 10 and the corresponding differential-mode magnetic core 20, the board area occupied by the inductor assembly 100 can be reduced, thereby saving the overall space of the power generation device, and under the same temperature rise, the cross-sectional area of ​​the annular winding 30 can be reduced, further reducing the manufacturing cost of the power generation device, and can also improve the overall efficiency of the power generation device. The axial directions of the multiple annular windings 30 are parallel to each other, which can improve the air-cooling heat dissipation effect of the inductor assembly 100.

[0044] According to some embodiments of the present invention, Figure 1 As shown, a plurality of differential mode cores 20 may be sequentially arranged along a first direction of the inductor assembly 100 , and a plurality of annular windings 30 may be sequentially arranged along the first direction, and the first direction is perpendicular to the axial direction of the first assembly hole 11 .

[0045] The first direction can be Figure 1 In the X direction shown in , multiple differential-mode cores 20 can be arranged in sequence along the first direction of the inductor assembly 100, and the central axes of the multiple differential-mode cores 20 are parallel, and the central axes of the differential-mode cores 20 are perpendicular to the central axis of the common-mode core 10, that is, the axial direction of the first assembly hole 11 is perpendicular to the axial direction of the second assembly hole 21, and multiple annular windings 30 all pass through the common-mode core 10 and the corresponding differential-mode core 20, so that the common-mode core 10 and the differential-mode core 20 can share the annular winding 30, which can reduce the board area of ​​the inductor assembly 100, thereby saving the overall space of the power generation device. Therefore, by arranging multiple differential-mode cores 20 in sequence along the first direction, and arranging multiple annular windings 30 in sequence along the first direction, the directions of the multiple annular windings 30 can be kept consistent, the air-cooling heat dissipation effect of the inductor assembly 100 can be improved, and under the same temperature rise, the cross-sectional area of ​​the annular winding 30 can be further reduced, the manufacturing cost of the power generation device can be further reduced, and the overall efficiency of the power generation device can be further improved.

[0046] According to some embodiments of the present invention, Figure 1 As shown, the central axes of the plurality of toroidal windings 30 may coincide.

[0047] Among them, the central axes of multiple annular windings 30 can overlap, and the axial directions of multiple annular windings 30 remain consistent, which is conducive to the wind flowing through the multiple annular windings 30 in sequence, and can further improve the air-cooling and heat dissipation effect of the inductor component 100. At the same temperature rise, the cross-sectional area of ​​the annular winding 30 can be further reduced, further reducing the manufacturing cost of the power generation device, and can also further improve the overall efficiency of the power generation device.

[0048] According to some embodiments of the present invention, Figure 2 As shown, a plurality of differential mode cores 20 can form a plurality of rows of differential mode cores, at least one row of differential mode cores includes a plurality of differential mode cores 20 arranged in sequence along a first direction of the inductor assembly 100, and the plurality of rows of differential mode cores are arranged in sequence along a second direction of the inductor assembly 100, and the first direction, the second direction and the axial direction of the first assembly hole 11 are perpendicular to each other.

[0049] Among them, multiple differential mode cores 20 can form multiple rows of differential mode core rows, for example: the number of rows of differential mode core rows can be two rows, three rows, four rows, etc., but the utility model is not limited to this. The number of rows of differential mode core rows can also be other numbers of rows, as long as multiple differential mode cores 20 can form multiple rows of differential mode core rows.

[0050] At least one row of differential-mode core rows includes a plurality of differential-mode cores 20 arranged in sequence along the first direction of the inductor component 100. For example, a plurality of rows of differential-mode core rows may have a row of differential-mode core rows including a plurality of differential-mode cores 20 arranged in sequence along the first direction of the inductor component 100, or a plurality of rows of differential-mode core rows may have two rows of differential-mode core rows including a plurality of differential-mode cores 20 arranged in sequence along the first direction of the inductor component 100. However, the present invention is not limited thereto. A plurality of rows of differential-mode core rows may also have other numbers of rows of differential-mode core rows including a plurality of differential-mode cores 20 arranged in sequence along the first direction of the inductor component 100, as long as at least one row of differential-mode core rows includes a plurality of differential-mode cores 20 arranged in sequence along the first direction of the inductor component 100.

[0051] The second direction can be Figure 2 In the Y direction shown, multiple rows of differential-mode magnetic cores can be arranged in sequence along the second direction of the inductor assembly 100, and the first direction, the second direction and the axial direction of the first assembly hole 11 are perpendicular to each other. This arrangement can reduce the length dimension of the inductor assembly 100 in the first direction, making the structure of the inductor assembly 100 more compact, further reducing the board area of ​​the inductor assembly 100, and further saving the overall space of the power generation device. In addition, since the differential-mode magnetic cores 20 and the annular windings 30 are assembled one by one, by arranging multiple rows of differential-mode magnetic cores in sequence along the second direction of the inductor assembly 100, multiple annular windings 30 can be staggered along the first direction, which can further improve the air-cooling and heat dissipation effect of the inductor assembly 100.

[0052] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, along the axial direction of the first assembly hole 11 , the plurality of differential mode magnetic cores 20 may be located on the same side of the common mode magnetic core 10 .

[0053] Among them, along the axial direction of the first assembly hole 11, multiple differential-mode magnetic cores 20 can be located on the same side of the common-mode magnetic core 10. Such a configuration can reduce the length dimension of the inductor component 100 in the axial direction of the first assembly hole 11, and the arrangement of the multiple differential-mode magnetic cores 20 is also more compact, thereby further reducing the board area occupied by the inductor component 100 and further saving the overall space of the power generation device.

[0054] According to some embodiments of the present invention, Figure 2 As shown, the multiple rows of differential mode cores may include: a first core row 22 and a second core row 23, the first core row 22 includes two differential mode cores 20, the second core row 23 includes one differential mode core 20, and along the second direction, the positive projection of the differential mode core 20 of the second core row 23 and the positive projection of multiple differential mode cores 20 of the first core row 22 have an overlapping area.

[0055] Among them, along the second direction, the orthographic projection of the differential mode core 20 of the second magnetic core row 23 and the orthographic projection of multiple differential mode cores 20 of the first magnetic core row 22 have an overlapping area. Such a setting can make the arrangement of multiple rows of differential mode core rows more dense, and make the structure of the inductor component 100 more compact, thereby further reducing the board area occupied by the inductor component 100 and further saving the overall space of the power generation device.

[0056] According to some embodiments of the present invention, Figure 3-Figure 5 As shown, each differential mode magnetic core 20 may include: a first magnetic core 24 and a second magnetic core 25. Along the axial direction of the first assembly hole 11, the first magnetic core 24 and the second magnetic core 25 are respectively located on both sides of the common mode magnetic core 10. The first magnetic core 24 and the second magnetic core 25 are both formed with a second assembly hole 21. The annular winding 30 is passed through the second assembly hole 21 of the corresponding first magnetic core 24 and the second assembly hole 21 of the second magnetic core 25.

[0057] Each differential mode magnetic core 20 may include: a first magnetic core 24 and a second magnetic core 25, and along the axial direction of the first assembly hole 11, the first magnetic core 24 and the second magnetic core 25 are respectively located on both sides of the common mode magnetic core 10, such as Figure 3 As shown, the present application takes the differential mode core 20 located on the upper side of the common mode core 10 as the first core 24 and the differential mode core 20 located on the lower side of the common mode core 10 as the second core 25 as an example for explanation. Such a configuration can configure the common mode core 10, the first core 24 and the second core 25 as a stacked structure, so that the inductor component 100 can obtain a higher differential mode inductance without increasing the board area of ​​the inductor component 100, and the height of the inductor component 100 is only slightly increased, thereby further saving the overall space of the power generation device.

[0058] The first magnetic core 24 and the second magnetic core 25 are both formed with a second assembly hole 21, and the annular winding 30 is inserted through the second assembly hole 21 of the corresponding first magnetic core 24 and the second assembly hole 21 of the corresponding second magnetic core 25. In this way, one annular winding 30 can be inserted through the second assembly hole 21 of the first magnetic core 24 and the second assembly hole 21 of the second magnetic core 25 at the same time, which can reduce the height dimension of the inductor component 100, further reduce the board area occupied by the inductor component 100, and at the same time increase the space utilization of the annular winding 30, reduce the use of copper wire, and further reduce the manufacturing cost of the inductor component 100.

[0059] According to some embodiments of the present invention, Figure 6-Figure 9 As shown, the differential mode core 20 may include: a first core body 26 and a second core body 27 , the first core body 26 and the second core body 27 are connected to jointly define a second assembly hole 21 , so that the annular winding 30 can be passed through the second assembly hole 21 .

[0060] According to some embodiments of the present invention, Figure 6 As shown, the first magnetic core body 26 and the second magnetic core body 27 have the same structure. The first magnetic core body 26 and the second magnetic core body 27 both include a first magnetic core segment 201, a second magnetic core segment 202 and a third magnetic core segment 203. The two ends of the second magnetic core segment 202 are respectively connected to one end of the first magnetic core segment 201 and one end of the third magnetic core segment 203. The first magnetic core segment 201 and the third magnetic core segment 203 extend toward the same side of the second magnetic core segment 202 and are spaced apart. The first magnetic core segment 201 of the first magnetic core body 26 and the first magnetic core segment 201 of the second magnetic core body 27 are butted against each other, and the third magnetic core segment 203 of the first magnetic core body 26 and the third magnetic core segment 203 of the second magnetic core body 27 are butted against each other, so that the first magnetic core body 26 and the second magnetic core body 27 define a second assembly hole 21. The first magnetic core body 26 and the second magnetic core body 27 can be fixed by bonding, or they can be fixed by snapping.

[0061] or, as Figure 7 and Figure 8 As shown, the first magnetic core body 26 includes a fourth magnetic core segment 204, a fifth magnetic core segment 205 and a sixth magnetic core segment 206, two ends of the fifth magnetic core segment 205 are respectively connected to one end of the fourth magnetic core segment 204 and one end of the sixth magnetic core segment 206, and the fourth magnetic core segment 204 and the sixth magnetic core segment 206 extend toward the same side of the fifth magnetic core segment 205, and the second magnetic core body 27 is constructed as a straight line segment, and the second magnetic core body 27 is connected to both the fourth magnetic core segment 204 and the sixth magnetic core segment 206, so that the first magnetic core body 26 and the second magnetic core body 27 define a second assembly hole 21.

[0062] Specifically, Figure 7As shown, the second core body 27 is located between the fourth core segment 204 and the sixth core segment 206, and the two ends of the second core body 27 are fixedly connected to the fourth core segment 204 and the sixth core segment 206, respectively, so that the first core body 26 and the second core body 27 define a second assembly hole 21. Figure 8 As shown, the first magnetic core body 26 and the second magnetic core body 27 are arranged opposite to each other, the other end of the fourth magnetic core segment 204 and the other end of the sixth magnetic core segment 206 are arranged opposite to the second magnetic core body 27, and the other end of the fourth magnetic core segment 204 and the other end of the sixth magnetic core segment 206 are fixedly connected to the second magnetic core body 27, so that the first magnetic core body 26 and the second magnetic core body 27 define a second assembly hole 21.

[0063] or, as Fig. 9 As shown, the first magnetic core body 26 and the second magnetic core body 27 have the same structure. The first magnetic core body 26 and the second magnetic core body 27 both include a seventh magnetic core segment 207, an eighth magnetic core segment 208, a ninth magnetic core segment 209 and a tenth magnetic core segment 210. One end of the eighth magnetic core segment 208, one end of the ninth magnetic core segment 209 and one end of the tenth magnetic core segment 210 are all connected to the seventh magnetic core segment 207, and the eighth magnetic core segment 208, the ninth magnetic core segment 209 and the tenth magnetic core segment 210 are oriented toward the seventh magnetic core segment 207. The eighth core segment 208, the ninth core segment 209 and the tenth core segment 210 are arranged in sequence along the length direction of the seventh core segment 207, and the eighth core segment 208, the ninth core segment 209 and the tenth core segment 210 of the first core body 26 are respectively connected with the eighth core segment 208, the ninth core segment 209 and the tenth core segment 210 of the second core body 27, so that the first core body 26 and the second core body 27 define a second assembly hole 21. It should be noted that in this embodiment, the first core body 26 and the second core body 27 can both be an "E"-shaped structure. After the first core body 26 and the second core body 27 are connected, the first core body 26 and the second core body 27 jointly define two second assembly holes 21, and the annular winding 30 passes through the first assembly hole 11 and the two second assembly holes 21 at the same time.

[0064] Therefore, the structure of each differential mode magnetic core 20 can be set and adjusted according to the actual situation, as long as it can meet the normal operation of the inductor assembly 100. The cross section of the magnetic core portion of the differential mode magnetic core 20 wound by the annular winding 30 can be rectangular or polygonal with an arc, thereby further reducing the winding size, reducing the cost of the inductor assembly 100, and making full use of the winding space of the second assembly hole 21.

[0065] According to some embodiments of the present invention, Figure 3-Figure 5 As shown, the axial directions of the second assembly holes 21 of the plurality of differential mode magnetic cores 20 may be parallel to each other.

[0066] Among them, the axial directions of the second assembly holes 21 of the multiple differential mode magnetic cores 20 can be parallel to each other, so as to ensure that the axial directions of the multiple annular windings 30 passing through the second assembly holes 21 remain consistent, thereby improving the air-cooling heat dissipation effect of the inductor component 100, thereby improving the overall efficiency of the power generation device.

[0067] According to some embodiments of the present invention, Figure 3-Figure 5 As shown, each differential mode magnetic core 20 may be spaced apart from the common mode magnetic core 10 , and the spacing distance between the differential mode magnetic core 20 and the common mode magnetic core 10 is positively correlated with the current of the toroidal winding 30 .

[0068] Among them, each differential mode core 20 can be set apart from the common mode core 10, for example: each differential mode core 20 can be separated from the common mode core 10 by using a PCB board, epoxy board or skeleton and other structural limits, but the utility model is not limited to this, each differential mode core 20 can also be separated from the common mode core 10 by other structures, as long as it can be ensured that each differential mode core 20 can be set apart from the common mode core 10, for example: using a spacer clamped between the differential mode core 20 and the common mode core 10 to separate the differential mode core 20 from the common mode core 10. In addition, the differential mode core 20 and the common mode core 10 can be fixed at different positions of the mounting frame to ensure that the differential mode core 20 is separated from the common mode core 10.

[0069] The spacing distance between the differential mode core 20 and the common mode core 10 is positively correlated with the current of the annular winding 30. It can also be understood that the larger the current of the annular winding 30, the larger the spacing distance between the differential mode core 20 and the common mode core 10, and the smaller the current of the annular winding 30, the smaller the spacing distance between the differential mode core 20 and the common mode core 10. The spacing distance between the differential mode core 20 and the common mode core 10 is reasonably designed according to the usage. The current of the annular winding 30 will generate magnetic fields inside the differential mode core 20 and the common mode core 10, respectively, which will interfere and couple with each other, thereby affecting the performance of the inductor component 100. Each differential mode core 20 can be spaced apart from the common mode core 10, which can reduce the interference between the differential mode core 20 and the common mode core 10, make the differential mode magnetic circuit and the common mode magnetic circuit independent of each other, and improve the anti-saturation characteristics of the differential mode inductance of the inductor component 100, thereby improving the performance of the inductor component 100.

[0070] The power generation device according to the embodiment of the utility model includes the above-mentioned inductor component 100, which can reduce the board area occupied by the inductor component 100, thereby saving the overall space of the power generation device, and under the same temperature rise, the cross-sectional area of ​​the annular winding 30 can be reduced, further reducing the manufacturing cost of the power generation device, and can also improve the air cooling and heat dissipation effect of the inductor component 100, and can also improve the overall efficiency of the power generation device.
