Description

Technical Field

[0001] This application relates to the technical field of transformers, and in particular to a transformer and a power supply. Background Technology

[0002] Due to its limited height, a 1U server power supply imposes strict requirements on the overall layout, height, and size of its internal electronic components, especially larger components like the transformer, whose height is subject to rigorous limitations. For the transformer, the industry typically uses copper sheets for secondary rectification. The primary and secondary windings are overlapped, and the secondary copper sheets extend out, either from one side or both sides of the transformer, and are soldered to the rectifier PCB. The transformer's secondary winding and secondary rectifier components share a common rectification circuit. However, this transformer structure is limited by the available board space (typically only 31mm) in a 1U power supply product.

[0003] To expand power output, an ISOP (Input-Series Output-Parallel) architecture is often used to expand a transformer into two or three, either discretely or magnetically integrated, to increase the power window. However, this approach often increases the iron loss of the transformer. Summary of the Invention

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the transformer provided in this application.

[0022] This application provides a transformer. For example... Figure 1and Figure 2 As shown, the transformer in this embodiment includes: a rectifier assembly 2, a primary winding 22, a magnetic core assembly 3, and a connecting assembly 4. The rectifier assembly 2 includes several circuit boards 21, which are arranged sequentially in one direction. Each circuit board 21 has opposing end faces. Specifically, the sequential arrangement of the circuit boards 21 in one direction means that the end faces of adjacent circuit boards 21 are opposite each other, i.e., the circuit boards 21 are distributed in parallel with each other at intervals. The circuit boards 21 integrate a secondary winding (not shown) and a rectifier network (not shown). The primary winding 22 is disposed between two adjacent circuit boards 21. The magnetic core assembly 3 is magnetically coupled to the primary winding 22 and the secondary winding, thereby completing the conversion and transmission of electrical energy to magnetic field energy and back to electrical energy, thus achieving the corresponding step-up and step-down operation, and working with the rectifier network to achieve stable DC signal transmission. Furthermore, the connection terminals 23 on several circuit boards 21 are electrically connected through the connection component 4. That is, when the rectifier component 2 outputs a DC signal, it can output through the connection component 4 connected to several circuit boards 21.

[0023] Specifically, the transformer can be a 1U high transformer, whose height is limited. Therefore, in this application, several circuit boards 21 are arranged sequentially along one direction to form a rectifier assembly 2. When power adjustment of the transformer is required, the number of circuit boards 21 can be adjusted according to the actual operating conditions, thereby adjusting the transformer's power. In other words, the sequential arrangement of several circuit boards 21 in the rectifier assembly 2 in this application allows for power adjustment of the rectifier assembly 2 without being limited by the transformer's height, thus adjusting the transformer's power. For example, when the transformer's power needs to be increased, the number of circuit boards 21 can be increased accordingly. Since the circuit boards 21 are arranged in one direction, increasing the number of circuit boards 21 only changes the transformer's width or length, without being limited by its height, thereby effectively ensuring the transformer's applicability and convenience.

[0024] Furthermore, several circuit boards 21 are used to form rectifier components 2, thereby eliminating the need for copper sheets for rectification, effectively reducing the impedance of AC signals, and reducing copper losses.

[0025] In an optional embodiment, the transformer further includes a magnetic core assembly 3, with a circuit board 21 disposed inside the magnetic core assembly 3. The magnetic core assembly 3 is magnetically coupled to the primary winding 22 and the secondary winding. That is, when an electrical signal is transmitted through the primary winding 22 to the rectifier assembly 2, the rectifier network in the rectifier assembly 2 rectifies the electrical signal, and the primary winding 22, the magnetic core assembly 3, and the secondary winding achieve corresponding step-up or step-down operation. Furthermore, the connection terminals 23 on the circuit board 21 extend out of the magnetic core assembly 3 and are electrically connected through a connection assembly 4. Thus, when multiple circuit boards 21 transmit electrical signals, the signals can be transmitted through the connection terminals 23 to the connection assembly 4, and then output through the connection assembly 4. Specifically, the connection terminals 23 of multiple circuit boards 21 are electrically connected to the secondary winding and the connection assembly 4, thereby realizing the transmission of electrical signals.

[0026] The connecting component 4 can be a metal part, such as a conductive metal like copper. In this application, the connecting component 41 is specifically a copper busbar. In other embodiments, it can also be other conductive parts, such as terminals, ribbon cables, etc. This application does not make specific limitations here.

[0027] In the above embodiments, the rectifier assembly 2 includes several circuit boards 21, on which secondary windings and rectifier networks are integrated. A primary winding 22 is provided between two adjacent circuit boards 21. The magnetic core assembly 3 is disposed inside the circuit board 21, and the connection end 23 on the circuit board 21 extends out of the magnetic core assembly 3. The connection assembly 4 realizes the electrical connection of the connection end 23 on the several circuit boards 21, thereby effectively improving the integration of the transformer, reducing the size of the transformer, and improving the layout capability of the transformer. Furthermore, the several circuit boards 21 are arranged sequentially in a certain direction, so that the transformer is not limited by the height of the transformer to adjust the power of the rectifier assembly 2, effectively ensuring the applicability and convenience of the transformer.

[0028] In an optional embodiment, the transformer in this application further includes a main board 1, and the rectifier assembly 2, the magnetic core assembly 3, and the connecting assembly 4 are all disposed on one side end face of the main board 1. The rectifier assembly 2 includes a plurality of circuit boards 21 arranged sequentially in one direction. Specifically, the plurality of circuit boards 21 are arranged sequentially along the width or length direction of the main board 1. Specifically, the end faces of the plurality of circuit boards 21 are perpendicular to one side end face of the main board 1, that is, the plurality of circuit boards 21 are perpendicularly disposed on one side end face of the main board 1, thereby forming a rectifier assembly 2 on one side end face of the main board 1.

[0029] In an optional embodiment, one end of the connecting component 4 is electrically connected to the rectifier component 2, and the other end is electrically connected to the motherboard 1, thereby making the rectifier component 2 and the motherboard 1 electrically connected. That is, when an electrical signal output is required, the electrical signal of the rectifier component 2 can be transmitted to the motherboard 1 through the connecting component 4, and then output through the motherboard 1.

[0030] In an optional embodiment, such as Figure 2 As shown, the motherboard 1 can be hollowed out, that is, a through slot 11 is formed on the motherboard 1. This through slot 11 can be used to accommodate the rectifier component 2. The width of the through slot 11 on the motherboard 1 can be set based on the width of the rectifier component 2, so that when the rectifier component 2 is installed on the motherboard 1, it can be placed within the through slot 11. It can be understood that when the rectifier component 2 is installed on the motherboard 1, the rectifier component 2 is at least partially placed within the through slot 11, and one end of the through slot 11 is flush with the side end face of the motherboard 1 away from the magnetic core component 3, thereby preventing the rectifier component 2 from extending beyond the end face of the motherboard 1, which would affect the layout of the power supply when the transformer is used in the power supply. In other embodiments, the through slot 11 may not be formed on the motherboard 1, that is, the rectifier component 2 is directly placed on one side end face of the motherboard 1. The specific setting can be set according to actual needs, and this application does not make specific limitations here.

[0031] In one optional embodiment, the motherboard 1 may have sockets corresponding to a plurality of circuit boards 21, that is, the plurality of circuit boards 21 can be inserted into the sockets, thereby fixing the plurality of circuit boards 21 on the motherboard 1 through the sockets, and can be used in conjunction with the connecting component 4 to fix the plurality of circuit boards 21. In other embodiments, the plurality of circuit boards 21 may also be fixed in other ways, which are not specifically limited in this application.

[0032] In an optional embodiment, the circuit board 21 is provided with at least one through hole 24, and the magnetic core assembly 3 is provided with magnetic posts 33 corresponding to the through hole 24. The magnetic posts 33 pass through the secondary winding through the through hole 24; the primary winding 22 is wound around the magnetic posts 33. That is, when the rectifier assembly 2 is magnetically coupled to the magnetic core assembly 3, the magnetic coupling is specifically achieved through the through hole 24 on the rectifier assembly 2 and the magnetic posts 33 located in the through hole 24. In this application, the rectifier assembly 2 includes three through holes 24 as an example, that is, three magnetic posts 33 are formed on the magnetic core assembly 3, and the three magnetic posts 33 are correspondingly arranged with the three through holes 24. The three magnetic posts 33 can be respectively located in the three through holes 24 of the rectifier assembly 2, thereby forming a three-magnetic-post 33 transformer. In other embodiments, the transformer can be a two-magnetic-pillar 33 transformer, that is, the rectifier assembly 2 has two through holes 24, and correspondingly, the magnetic core assembly 3 has two magnetic pillars 33, which are arranged corresponding to the two through holes 24. When the transformer is installed, the two magnetic pillars 33 can be located in the two through holes 24 respectively, thereby forming a two-magnetic-pillar 33 transformer. Correspondingly, the transformer can also be a single-magnetic-pillar 33 transformer, etc., which can be set according to actual needs, and this application does not make specific limitations.

[0033] In an optional embodiment, such as Figure 2 As shown, the magnetic core assembly 3 includes a first magnetic core 31 and a second magnetic core 32, which are distributed on opposite end faces of the rectifier assembly 2. A first magnetic post 311 is disposed on the first magnetic core 31, and a second magnetic post 321 is disposed on the second magnetic core 32. The first magnetic post 311 and the second magnetic post 321 abut against each other to form a magnetic post 33. It can be understood that the magnetic post 33 passes through the secondary winding via a through hole 24, and the primary winding 22 is wound around the magnetic post 33. Since the circuit board 21 has at least one through hole 24, the first magnetic post 311 and the second magnetic post 321 each have the same number of through holes 24, meaning the number of first magnetic posts 311 and the number of second magnetic posts 321 are the same as the number of through holes 24 on the same circuit board 21. Several first magnetic posts 311 and several second magnetic posts 321 are arranged in a one-to-one correspondence to form corresponding magnetic posts 33. The first magnetic core 31 and the second magnetic core 32 can be symmetrically arranged, that is, the symmetrically arranged first magnetic core 31 and second magnetic core 32 can be arranged opposite each other on the opposite end faces of the rectifier assembly 2. That is, while fixing several circuit boards 21 through the motherboard 1 and the connecting assembly 4, several circuit boards 21 can also be fixed through the first magnetic core 31 and the second magnetic core 32.

[0034] In this embodiment, the first magnetic post 311 on the first magnetic core 31 and the second magnetic post 321 on the second magnetic core 32 are symmetrically arranged, so that when the first magnetic core 31 and the second magnetic core 32 are arranged on opposite sides of several circuit boards 21, the first magnetic core 31 and the second magnetic core 32 are in contact with each other. Specifically, the first magnetic post 311 on the first magnetic core 31 and the second magnetic post 321 on the second magnetic core 32 abut against each other to form a magnetic post 33, so that the magnetic post 33 is located in the through hole 24 of the rectifier assembly 2. Furthermore, the first magnetic post 311 on the first magnetic core 31 and the second magnetic post 321 on the second magnetic core 32 can be used to limit the movement of several circuit boards 21.

[0035] In an optional embodiment, the first magnetic core 31 has first side posts 312 at both ends, with a first magnetic post 311 located between the two first side posts 312; the second magnetic core 32 has second side posts 322 at both ends, with a second magnetic post 321 located between the two second side posts 322; the two first side posts 312 and the two second side posts 322 correspond one-to-one and abut against each other. Thus, a cavity is formed when the two first side posts 312 and the two second side posts 322 abut against each other, and several circuit boards 21 can be located in this cavity. The first magnetic post 311 on the first magnetic core 31 is located between two first side posts 312. Correspondingly, the second magnetic post 321 on the second magnetic core 32 is located between two second side posts 322. When the first magnetic core 31 and the second magnetic core 32 are in contact, the magnetic posts 33 formed by the first magnetic post 311 and the second magnetic post 321 are located in the through holes 24 of several circuit boards 21. That is, the magnetic posts 33 formed by the first magnetic post 311 and the second magnetic post 321 can generate magnetic field energy when the electrical signal is transmitted to the primary winding 22. The magnetic field energy is converted into electrical energy in conjunction with the secondary winding integrated on the rectifier assembly 2, thereby outputting the corresponding electrical signal after realizing the boost and buck.

[0036] In an optional embodiment, the power of the transformer can be adjusted by changing the number of circuit boards 21. It can be understood that when the number of circuit boards 21 is adjusted, the width of the rectifier assembly 2 will change with the number of circuit boards 21. Based on this, when adjusting the power of the transformer, the dimensions of the first magnetic core 31 and the second magnetic core 32 can be adjusted relative to each other. That is, the dimensions of the first magnetic post 311 and the two first side posts 312 on the first magnetic core 31, and the second magnetic post 321 and the two second side posts 322 on the second magnetic core 32 can be adjusted. Thus, when the first magnetic core 31 and the second magnetic core 32 are set on opposite sides of the rectifier assembly 2, the two first side posts 312 on the first magnetic core 31 can abut against the two second side posts 322 on the second magnetic core 32 in a one-to-one correspondence. This ensures that the cavity formed by the two first side posts 312 and the two second side posts 322 can accommodate a number of circuit boards 21, and ensures that the first magnetic post 311 on the first magnetic core 31 and the second magnetic post 321 on the second magnetic core 32 abut against each other in a one-to-one correspondence to form a magnetic post 33.

[0037] In an optional embodiment, the circuit board 21 is provided with a plurality of through holes 24, which are arranged in an array along the length of the circuit board 21. The number of magnetic pillars 33 is the same as the number of through holes 24 on each circuit board 21, and the magnetic pillars 33 correspond one-to-one with the through holes 24. That is, the number of first magnetic pillars 311 on the first magnetic core 31 is the same as the number of through holes 24, and the number of second magnetic pillars 321 on the second magnetic core 32 is the same as the number of through holes 24. The number of magnetic pillars 33 formed by the first magnetic pillars 311 and the second magnetic pillars 321 abutting is the same as the number of through holes 24, so that when the magnetic core assembly 3 and the rectifier assembly 2 are magnetically coupled, the magnetic pillars 33 formed by the one-to-one abutment of the first magnetic pillars 311 and the second magnetic pillars 321 can be located one-to-one within the through holes 24, thereby realizing the magnetic coupling between the magnetic core assembly 3 and the primary winding 22 and the secondary winding.

[0038] In an optional embodiment, the connection component 4 includes at least one connector 41, one end of which is electrically connected to the end of the rectifier component 2 away from the motherboard 1, and the other end is electrically connected to the motherboard 1. In this application, an example is provided with three magnetic pillars 33, meaning the rectifier component 2 includes three through holes 24 and the magnetic core component 3 includes three magnetic pillars 33. In this case, the connection component 4 includes two connectors 41, one end of which is electrically connected to the rectifier component 2, and the other end of which is electrically connected to the motherboard 1.

[0039] In one optional embodiment, the connector 41 has a plurality of fixing holes 413 corresponding to a plurality of circuit boards 21; the connecting ends 23 on the plurality of circuit boards 21 correspond one-to-one with the plurality of fixing holes 413, and the plurality of connecting ends 23 extend into the corresponding fixing holes 413 to realize the electrical connection of the plurality of circuit boards 21. Specifically, the plurality of fixing holes 413 and the plurality of connecting ends 23 on the plurality of circuit boards 21 are detachably connected. It is understood that when connecting the rectifier assembly 2 and the main board 1 through the connector 41, the connection can be achieved by soldering. In other embodiments, other connection methods can also be used, and this application does not specifically limit them here. In order to ensure the stability and structural strength of the connection between the connector 41 and the rectifier assembly 2, a plurality of fixing holes 413 can be opened on the connector 41, and connecting ends 23 can be correspondingly provided on the plurality of circuit boards 21, that is, each circuit board 21 is provided with a connecting end 23, and the connecting end 23 extends out of the corresponding fixing hole 413. When connecting the connector 41 to the rectifier assembly 2, the connector 41 can be plugged into the corresponding connection terminals 23 on the circuit boards 21 through the fixing holes 413 on the connector 41, thereby completing the electrical connection between the connector 41 and the circuit boards 21.

[0040] In this embodiment, when installing the transformer, several circuit boards 21 can be arranged sequentially in advance, and a rectifier network and secondary windings can be integrated on the circuit boards 21 to form a rectifier assembly 2. When forming the rectifier assembly 2, a primary winding 22 is set between two adjacent circuit boards 21. The rectifier assembly 2 is then set on one end face of the main board 1, and then the first magnetic core 31 and the second magnetic core 32 are set on the main board 1, with the first magnetic core 31 and the second magnetic core 32 set on opposite end faces of the rectifier assembly 2. In other embodiments, several circuit boards 21 integrating secondary windings and rectifier networks can be arranged sequentially to form the rectifier assembly 2, and then the rectifier assembly 2 can be fixed by the first magnetic core 31 and the second magnetic core 32. Then, the whole assembly formed by the first magnetic core 31, the second magnetic core 32 and the rectifier assembly 2 can be installed on the main board 1. When the rectifier assembly 2 is fixed by the first magnetic core 31 and the second magnetic core 32, the first magnetic post 311 on the first magnetic core 31 and the second magnetic post 321 on the second magnetic core 32 abut against each other to form a magnetic post 33 in the through hole 24 of the rectifier assembly 2. After the magnetic core assembly 3 and the rectifier assembly 2 are installed on the motherboard 1, the electrical connection between the rectifier assembly 2 and the motherboard 1 can be achieved through the connector 41. When installing the connector 41, the fixing hole 413 on the connector 41 can be inserted into the corresponding connection terminal 23 on several circuit boards 21, so that the connector 41 is limited and fixed by the connection terminal 23 on several circuit boards 21. After the connector 41 is fixed on several circuit boards 21, the electrical connection between the rectifier assembly 2 and the connector 41 can be achieved by soldering, and then the connection between the connector 41 and the motherboard 1 can be achieved by soldering, thereby completing the installation of the transformer.

[0041] In an optional embodiment, such as Figure 3 At Figure 4 As shown, connector 41 includes a first connecting portion 411 and a second connecting portion 412. The first connecting portion 411 and the second connecting portion 412 are connected. The first connecting portion 411 is electrically connected to the rectifier assembly 2, and the second connecting portion 412 is an output terminal. Specifically, the second connecting portion 412 can be connected to the motherboard 1 and is located on the end face of the magnetic core assembly 3 away from the rectifier assembly 2. Figure 3 As shown, the connector 41 can be configured as an "L-shaped" structure, thereby ensuring electrical connection between the rectifier assembly 2 and the motherboard 1 while allowing the first connecting part 411 and the second connecting part 412 to fit against the magnetic core assembly 3 and the rectifier assembly 2, thus effectively improving the space utilization of the transformer. In this application, the first connecting part 411 and the second connecting part 412 are arranged perpendicularly. For example, when the rectifier assembly 2 is connected to the motherboard 1 through the connector 41, the first connecting part 411 can fit against the side of the rectifier assembly 2 away from the motherboard 1, and the second connecting part 412 can fit against the side of the magnetic core assembly 3 away from the rectifier assembly 2, that is, the second connecting part 412 is arranged perpendicular to the side of the motherboard 1. In other embodiments, the second connecting part 412 connected to the first connecting part 411 can be set at a preset angle to the first connecting part 411. The angle between the first connecting part 411 and the second connecting part 412 can be set according to actual needs, and this application does not make specific limitations here.

[0042] In an optional embodiment, such as Figure 4 and Figure 5 As shown, two second connecting parts 412 are provided. The two second connecting parts 412 are respectively connected to both ends of the first connecting part 411, and the other end is connected to the motherboard 1. The two second connecting parts 412 are respectively provided on the opposite end faces of the magnetic core assembly 3. Specifically, the first connecting part 411 has a second connecting part 412 at both ends. The two second connecting parts 412 serve as output ends and can be connected to the motherboard 1. That is, the rectifier assembly 2 can be connected to the motherboard 1 through the first connecting part 411 and the two second connecting parts 412. That is, the connector 41 has a "U-shaped" structure.

[0043] In an optional embodiment, such as Figure 6 and Figure 7 As shown, an inductor assembly 5 is provided on the second connecting part 412. Specifically, since the connector 41 is used to transmit DC signals, the inductor assembly 5 is fitted onto the connector 41 to filter AC current and reduce AC interference. Specifically, as... Figure 6As shown, taking a connector 41 with a first connecting part 411 and a second connecting part 412 as an example, the connector 41 has an "L-shaped" structure. When the connector 41 is set on the rectifier assembly 2, the inductor assembly 5 can be set on the second connecting part 412. That is, the second connecting part 412 and the magnetic core assembly 3 are spaced apart, so that the inductor assembly 5 can be sleeved on the second connecting part 412.

[0044] In an optional embodiment, for example, a second connecting portion 412 is provided at both ends of the first connecting portion 411, such as... Figure 7 As shown, when the connector 41 is disposed on the rectifier assembly 2, inductor assemblies 5 can be disposed on both second connection portions 412. In other embodiments, inductor assemblies 5 can be disposed on both connectors 41, and the inductor assemblies 5 are correspondingly disposed on the second connection portions 412 of the connector 41. This application does not make specific limitations here.

[0045] In an optional embodiment, when the transformer is working, the electrical signal can be transmitted to several circuit boards 21 through the primary winding 22. The through holes 24 of the several circuit boards 21 are magnetically coupled to the magnetic core assembly 3, that is, the primary winding 22 is magnetically coupled to the magnetic column 33, thereby converting electrical energy into magnetic field energy. Then, the magnetic field energy is converted into electrical energy through the magnetic column 33 and the secondary winding, thereby completing the corresponding voltage boost and voltage buck. During voltage boost and voltage buck, the electrical signal can be rectified through the rectifier network in the rectifier assembly 2, and the electrical signal is transmitted to the main board 1 through the connector 41. When the signal is transmitted to the main board 1, the AC signal can be filtered by the inductor assembly 5 provided on the second connection part 412 to reduce interference with the DC signal, and then the signal is output through the main board 1.

[0046] Unlike the prior art, this application discloses a power supply that includes a transformer, which is the transformer of any of the above embodiments.

[0047] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
