[0032] To address the issues of high production costs and limited safety distances in existing technologies, the following will be discussed in conjunction with the appendix. Figures 1 to 5 A magnetically combined PFC inductor provided in the embodiments of this utility model will be described in detail.

[0033] Please see Figures 1 to 4 , Figure 1 This is an exploded view of a magnetically combined PFC inductor according to an embodiment of the present invention; Figure 2 This is a first partial exploded view of a magnetically combined PFC inductor according to an embodiment of the present invention.

[0034] A magnetically combined PFC inductor, comprising:

[0035] Magnetic core 1, at least three pieces are provided and are parallel to each other;

[0036] At least two coil frame groups 2 are provided. Each coil frame group 2 is located between two adjacent magnetic cores 1. Each coil frame group 2 includes two symmetrically arranged coil frames. Each coil frame includes a mounting tube 202 and a baffle 204. One end of the mounting tube 202 is connected to the baffle 204 and an opening is provided on the baffle 204.

[0037] At least two sets of magnetic pillars 3 are provided corresponding to the coil frame group 2. Each set of magnetic pillars 3 is located between two adjacent magnetic cores 1. The two ends of each magnetic pillar 3 pass through the mounting tube 202 and the opening of each coil frame and are connected to the magnetic core 1.

[0038] The vertically wound coil 4 is provided in at least two sets corresponding to the coil frame group 2, with each set of vertically wound coils being sleeved on the outer wall of the mounting tube of each set of coil frame group.

[0039] Specifically, magnetic core 1 shall be provided in at least three parts, including a first magnetic core 11, a second magnetic core 12 and a third magnetic core 13 that are spaced apart and parallel to each other;

[0040] Coil frame group 2, at least two groups are provided, including a first coil frame group 21 and a second coil frame group 22. The first coil frame group 21 is located between the first magnetic core 11 and the second magnetic core 12, and the second coil frame group 22 is located between the second magnetic core 12 and the third magnetic core 13. Each coil frame group includes two symmetrically arranged coil frames. Each coil frame group 2 includes a mounting tube 202 and a baffle 204. One end of the mounting tube 202 is connected to the baffle 204 and has an opening on the baffle 204. The mounting tube 202 includes an inner wall 2021 and an outer wall 2022.

[0041] The magnetic pillars 3 are provided in at least two groups, including a first magnetic pillar group 31 and a second magnetic pillar group 32.

[0042] The vertically wound coil 4 is provided in at least two sets corresponding to the coil frame group 2, including a first vertically wound coil group 41 and a second vertically wound coil group 42, which are respectively sleeved on the outer wall 2022 of the mounting tube 202 of the two sets of coil frame groups.

[0043] The vertically wound coils 4 are arranged along the same line of magnetic field lines. Three or four magnetic cores 1 can be used. Adjacent vertically wound coils 4 can share the same magnetic core 1, reducing the number of magnetic cores 1 by two to three. The magnetic core 1 is a sheet-like, simple shape, easy to assemble and splice, offering greater flexibility. The vertically wound coils 4 are wound left and right together for automated winding. The magnetic column 3 has a simple shape, is easy to assemble and splice, and offers greater flexibility. Reducing the length by the size of multiple magnetic cores 1 reduces the amount of raw materials used, lowering costs. This scheme is suitable for inductors with different power ratings and number of phases. The magnetic core 1 provides magnetic flux transmission, the coil frame 2 fixes the magnetic core 1, and the vertically wound coils 4 are used for excitation and flux transmission.

[0044] Please see Figure 3 , Figure 3 This is a second partially exploded view of a magnetically combined PFC inductor according to an embodiment of the present invention.

[0045] In one embodiment, the coil frame group 2 includes a first coil frame group 21 and a second coil frame group 22. The first coil frame group 21 includes a first frame 211 and a second frame 212. The second coil frame group 22 includes a third frame 221 and a fourth frame 222. The first magnetic core 11 is disposed outside the first frame 211. The second magnetic core 12 is disposed between the second frame 212 and the third frame 221. The third magnetic core 13 is disposed outside the fourth frame 222. The second frame 212 and the third frame 221 are arranged back to back.

[0046] Specifically, the first coil frame group 21 has two coil frames, including the first frame 211 and the second frame 212, and the second coil frame group 22 has two coil frames, including the third frame 221 and the fourth frame 222. A magnetic post 3 and a vertically wound coil 4 are arranged between the first frame 211 and the second frame 212, and a magnetic post 3 and a vertically wound coil 4 are arranged between the third frame 221 and the fourth frame 222. The coil frame group 2 is used to support the vertically wound coil 4, isolate the magnetic core 1, and dissipate heat from the magnetic post 3.

[0047] In one embodiment, each coil frame group 2 has two mounting tubes 202 arranged symmetrically, each mounting tube 202 protruding from the baffle 204, and the four mounting tubes 202 of each coil frame group 2 protruding inward and inserted into the end of the vertical winding coil 4 group, with the inner wall of the vertical winding coil 4 and the outer wall 2022 of the mounting tube 202 in contact.

[0048] Specifically, the inward protrusion of the mounting tube 202 facilitates the installation of the vertically wound coil 4, and is used to fix the magnetic post 3 and the vertically wound coil 4. The magnetic post 3 is inserted into the mounting tube 23, and the mounting tube 23 is inserted into the vertically wound coil 4, that is, the vertically wound coil 4 is sleeved on the outside of the mounting tube 23. The mounting tube 23 can fix the same set of magnetic posts 3 and vertically wound coil 4.

[0049] In one embodiment, the inner diameter of the vertically wound coil 4 is larger than the outer diameter of the magnetic post 3, and the vertically wound coil 4 does not come into contact with the magnetic post 3.

[0050] Specifically, the mounting tube 202 on the coil frame assembly 2 has a certain thickness, the magnetic post 3 is inserted into the mounting tube 202 of the coil frame assembly 2, and the vertical winding coil 4 is nested outside the mounting tube 202 on the coil frame assembly 2. Therefore, the distance between the magnetic post 3 and the coil frame assembly 2 is the thickness of the mounting tube 202.

[0051] By keeping the vertically wound coil 4 and the magnetic core 1 out of contact, heat loss can be avoided, improving the stability and lifespan of the inductor. The main function of the PFC inductor is to improve the power factor and reduce reactive power, thereby improving energy utilization efficiency. Keeping them out of contact reduces electromagnetic interference, ensuring stable system operation, and reduces mechanical stress caused by direct contact, thus extending the inductor's lifespan and improving its reliability.

[0052] In one embodiment, the inner diameter of the mounting tube 202 is larger than the outer diameter of the magnetic column 3. The magnetic column 3 is inserted into the mounting tube 202 and the end of the magnetic column 3 passes through the mounting tube 202 and the opening and contacts the magnetic core 1. The vertical winding coil 4 is sleeved on the outer wall 2022 of the mounting tube 202, and the end of the vertical winding coil 4 contacts the baffle 204.

[0053] Specifically, the mounting tube 202 is open at both ends. Near the connection point with the baffle 204, the baffle 204 has an opening. The magnetic post 3 passes through the mounting tube 202, with its end contacting the magnetic core 1. The side of the magnetic post 3 contacts the inner wall 2021 of the mounting tube 202. The magnetic core 1 can increase the magnetic flux of the inductor, thereby increasing the inductance value. The magnetic core 1 is typically made of materials such as ferrite, ferrite alloy, and nickel-zinc alloy, which have high permeability and low energy loss characteristics.

[0054] Without the magnetic core 1, the inductor can only generate magnetic flux by its own vertical winding coil 4. When the magnetic core 1 is used, the magnetic core 1 will absorb the external magnetic field, enhance the magnetic flux of the inductor, and thus increase the inductance value of the inductor. Therefore, the end of the magnetic column 3 passes through the mounting tube 202 and contacts the magnetic core 1, which can increase the magnetic flux.

[0055] The baffle 204 is in close contact with the end of the vertical winding coil 4, which can fix the vertical winding coil 4, prevent the vertical winding coil 4 from moving, and enhance stability and reliability.

[0056] In one embodiment, the side of the magnetic column 3 includes four planes and four arc surfaces, which are alternately distributed. The side shapes of the mounting tube 202, the magnetic column 3, and the vertical winding coil 4 are the same.

[0057] Specifically, the vertical winding coil 4 is typically cubic or cylindrical in shape, capable of withstanding higher voltages and exhibiting more stable power transmission. It is generally a flat, elongated wire with an elliptical cross-section. Multiple planes and curved surfaces facilitate the winding of the vertical winding coil 4, reducing the bending amplitude. The vertical winding coil 4 employs left and right coil winding, with automated winding. The magnetic column 3 has a simple shape, is easy to assemble and splice, and offers greater flexibility.

[0058] In one embodiment, the first magnetic column group 31 and the second magnetic column group 32 are spaced apart by the second magnetic core 12, and the first vertical winding coil group 41 and the second vertical winding coil group 42 are spaced apart by the second frame 212, the second magnetic core 12 and the third frame 221.

[0059] Please participate Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the installation of a magnetically combined PFC inductor according to an embodiment of this utility model. Figure 5 This is a three-dimensional structural diagram of a mounting base for a magnetically combined PFC inductor according to an embodiment of this utility model.

[0060] In one embodiment, a mounting base 5 is also included. The mounting base 5 includes a base plate 51 and a side wall 52. The base plate 51 and the side wall 52 form an accommodating space for placing the magnetic core 1 and the vertically wound coil 4. The magnetic core 1 and the vertically wound coil 4 are placed in the accommodating space of the mounting base 5 and fit against the mounting base 5. Along the top view direction, the side wall 52 is fitted with the shape of the magnetic core 1 and the vertically wound coil 4.

[0061] Specifically, the mounting base 5 is made of plastic and serves as insulation. The mounting base 5 has vertical side walls 52 that serve as isolation around the vertically wound coil 4. The pin leads out and is fixed. The mounting base 5 surrounds the vertically wound coil 4 to meet the safety distance requirements between the vertically wound coil 4 and the housing, thereby enhancing the safety performance of the product.

[0062] In one embodiment, the sum of the outer diameters of the two vertically wound coils 4 is the same as the width of the baffle 204 and greater than the width of the magnetic core 1. The vertically wound coils 4 and the coil frame assembly 2 and the magnetic core 1 are recessed inward at the position of the magnetic core 1 to form a groove. The side wall of the mounting base 5 is provided with a protrusion 521. The protrusion 521 of the mounting base 5 is engaged with the groove to fix the coil frame assembly 2 and the magnetic core 1.

[0063] Specifically, the groove and protrusion 521 can be used to fix the magnetic core 1 and the vertical winding coil 4. At the same time, the magnetic column 3 and the coil frame group 2 are located inside the vertical winding coil 4 and are indirectly fixed, which enhances its safety performance. Compared with the existing technology where each group of inductors is set independently and the upper and lower magnetic cores are added with magnetic columns, in this utility model, the magnetic column 3 and the vertical winding coil 4 are changed from vertical to horizontal placement, and the polarity ends are set on the same line. The mounting base 5 fixes their positions. In this way, two adjacent vertical winding coils 4 can share the same magnetic core 1, reducing the number of magnetic cores 1 and reducing costs. The reduction in the number of magnetic cores 1 can save the size and volume of the mounting base 5 and reduce the amount of potting glue.

[0064] In some embodiments, the base plate 51 is provided with a plurality of fixing holes 511 for passing through the pins of the terminals of the vertical winding coil 4, and the pins are led out from the fixing holes 511.

[0065] Specifically, the terminal of the vertical winding coil 4 is a PIN. The purpose of setting the fixing hole 511 is to fix the PIN of the vertical winding coil 4. Since the magnetic column 3 and the coil frame are fixed by the vertical winding coil 4, and the end of the magnetic column 3 is bonded to the magnetic core 1, the PIN of the vertical winding coil 4 can be fixed to the magnetic core 1, the magnetic column 3, the coil frame group 2 and the vertical winding coil 4.

[0066] Beneficial effects: This utility model proposes a magnetic combination PFC inductor. The magnetic core 1 and magnetic column 3 are simple, easy to assemble, and have a high degree of flexibility. The vertical winding coil 4 isolates the magnetic core 1. By changing the placement of the magnetic column 3 and the vertical winding coil 4 from vertical to horizontal, and setting the polarity ends on the same line, they share a single magnetic core 1. The mounting base 5 fixes its position, which can reduce the amount of magnetic core used, save the volume of the mounting base 5, and reduce the amount of potting compound. The mounting base 5 surrounds the vertical winding coil 4 on all sides to meet the safety distance requirements between the vertical winding coil 4 and the housing.

[0067] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above.
