Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] The present disclosure claims priority to Chinese patent applications with application numbers 202311412844.2 and 202322907300.5, filed on October 27, 2023, and entitled “A rectifier module and transformer”, and Chinese patent applications with application numbers 202410302855.3 and 202420513644.X, filed on March 15, 2024, and entitled “A rectifier module and transformer”, the entire contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] The present disclosure relates to the field of power electronics technology, and in particular to a rectifier module and a transformer. Background Art

[0004] As people's requirements for smart life increase, society's demand for data processing is growing. The global energy consumption for data processing reaches hundreds of billions or even trillions of degrees per year on average; and a large data center can occupy tens of thousands of square meters. Therefore, high efficiency and high power density are key indicators for the healthy development of this industry.

[0005] As the integration of electrical devices per unit volume continues to increase, the electricity that powers these electrical devices is expected to have higher efficiency, higher power density and smaller volume to support the overall power demand. In order to meet the demand for high power density, the demand for low-voltage, high-current power supplies is increasing. With the development of low-voltage, high-current power supplies, the processing of high-current windings has become increasingly important. The form of the winding must not only cooperate with the placement of the secondary rectifier tube, but also have high manufacturability.

[0006] At the same time, in a high current environment, there is a proximity effect problem between adjacent transmission lines. The so-called proximity effect problem in a two-wire transmission line refers to the phenomenon that the AC current in the two conductors approaches the adjacent conductors. The proximity effect problem will cause the resistance of adjacent transmission lines to increase, thereby increasing the power loss on the line and affecting the power supply efficiency. Therefore, for low-voltage and high-current transformers, the design of the rectifier board is also particularly important. A poor design will cause the rectifier board to have excessive losses, low efficiency, excessive heat, and potential safety hazards.

[0007] However, the prior art still lacks a targeted solution to the proximity effect problem in the design of the transformer and rectifier board of the power supply. Therefore, how to design the transformer and rectifier board to avoid the proximity effect problem and improve the power supply efficiency has become a technical problem to be solved in this field.

The transformer 110 includes: a magnetic core 113, a first winding 111 and a second winding 112. The transformer 110 changes the AC voltage through the first winding 111 and the second winding 112. The rectifier board 120 includes a plurality of switch element groups ( Figure 1A The rectifier board 120 is electrically connected to the transformer 110, and is used to rectify the alternating current of the transformer 110 into direct current. It should be noted that, for the sake of simplicity, the switching elements on the rectifier board 120 are not shown in the figure, and the rectifier board 120 here is only used for illustration. In addition, in other embodiments of the present case, a substrate (not shown in the figure) can be further arranged between the transformer 110 and the rectifier board 120, and a through hole is reserved on the substrate for the comb-type pins of the second winding 112 to pass through, so as to fix the second winding 112.

[0118] like Figure 1BAs shown, the transformer 110 includes: a magnetic core 113, a first winding 111 and a second winding 112. The first winding 111 is composed of a coil and is used to receive the input alternating current. The magnetic core 113 includes a magnetic column 118, and the coil constituting the first winding 111 is arranged on the magnetic column 118. The magnetic core 113 mainly plays a magnetic conductive role. The second winding 112 is arranged on the outside of the first winding 111, and is used to electrically connect to the rectifier board 120, and input the alternating current output by the transformer 110 into the rectifier board 120 for rectification. Comb-type pins 1121 are respectively arranged on opposite sides of the second winding 112. The comb-type pins 1121 are arranged along the first direction X. The comb-type pins 1121 include at least two comb teeth 1121A, and a comb space 1121B is arranged adjacent to the comb teeth 1121A. The comb-type pin 1121 is arranged alternately by a plurality of comb teeth 1121A and comb spaces 1121B, presenting a comb-like structure. The transformer 110 is electrically connected to the rectifier plate 120 through the comb teeth 1121A. It should be noted that the shape of the comb-type pin 1121 shown in the figure is only an example. In other embodiments, the shape of the comb-type pin 1121 is not limited, and as long as an electrical connection can be made, it should be considered to belong to the protection scope of this case. In some embodiments of the present case, the magnetic column 118 is a cylinder, and the axial direction of the magnetic column 118 is the first direction X.

[0119] The so-called opposite sides of the second winding 112 refer to the two ends of the second winding 112, and their specific positions are related to the shape and structure of the second winding 112. For example, Figure 1B The opposite sides of the second winding 112 are opposite sides along the second direction Y. Figure 5A The opposite sides of the second winding 512 are shown as opposite sides along the third direction Z.

[0120] Please refer to Figure 1B , wherein the second winding 112 is U-shaped, wherein the comb-shaped pins are arranged at two free ends of the U-shaped second winding 112. In other embodiments of the present case, the second winding 112 may also be in other shapes, and the present case is not limited thereto.

[0121] In an exemplary embodiment, the second winding 112 may be a metal sheet or a PCB winding. Specifically, the metal sheet includes iron sheets, copper sheets, aluminum sheets, nickel sheets, tungsten sheets, molybdenum sheets, cobalt sheets, etc., and also includes metal sheets made of various metal alloys, including stainless steel sheets, nickel-based alloy sheets, copper alloy sheets, and aluminum alloy sheets. The PCB winding may be a flexible PCB winding or a rigid PCB winding. For example, in Figure 1B In the embodiment shown, the second winding 112 may also be a flexible PCB winding, thereby being bent into a U-shaped winding. Figure 1C In the embodiment shown, the second winding 112 may also be a rigid PCB winding. Figure 1CIn the illustrated embodiment, except for the different material used for the second winding 112, the other parts are the same as those of the aforementioned embodiment in structure, and will not be described in detail here.

[0122] In an exemplary embodiment, if Figure 1B As shown, the comb-type pins 1121 and the rectifier plate 120 can be welded through via holes. In other embodiments of the present invention, such as Fig. 1I As shown, the comb-type pins 1121 and the rectifier plate 120 can also be welded by surface mounting.

[0123] It should be noted that the first direction X, the second direction Y, and the third direction Z referred to in the present disclosure are all set based on the circuit board. When the position of the circuit board changes, the first direction X, the second direction Y, and the third direction Z may be different according to different embodiments, such as Figure 1A and 1C shown.

[0124] In some embodiments of the present invention, Figure 1B and Figure 1H As shown, the magnetic column 118 extends along the first direction X, and the second winding 112 includes a main body 1122 (eg Figure 1B The comb-type pin 1121 (shown in the dashed box) Figure 1B and 1H The main body 1122 includes a first end 1122A and a second end 1122B that are relatively arranged along the first direction X, and a third end 1122C and a fourth end 1122D that are relatively arranged, wherein a comb-type pin 1121 is connected to the third end 1122C and the fourth end 1122D, and the main body 1122 extends along the first direction. That is, the extension direction of the main body 1122 of the second winding 112 is the same as the extension direction of the magnetic column 118. In an exemplary embodiment, the second winding 112 is integrally formed, and in other embodiments of the present case, the second winding 112 may include a plurality of sub-windings. Each sub-winding may include a comb-type pin, and each sub-winding may also be integrally formed. At the same time, the sub-windings may be arranged in a variety of ways, for example Figure 5A and 6A The second winding shown is composed of a plurality of half-turn windings. In other embodiments of the present invention, each of the plurality of sub-windings forming the second winding may not have a comb-type pin-out, for example Figure 2A and 2B The second winding shown is composed of a plurality of coils, and the pins on both sides of the coil group composed of the plurality of coils are comb-type pins.

[0125] In an exemplary embodiment, if Figure 1EAs shown, the magnetic core 113 includes at least two magnetic columns. Exemplarily, the at least two magnetic columns of the magnetic core 113 are arranged along the second direction Y. The first winding 111 and the second winding 112 are disposed on the at least two magnetic columns. It should be noted that the magnetic column referred to here refers to a magnetic column with a winding disposed thereon, such as Figure 1A , 1B In the embodiments shown in the above, in addition to the magnetic columns with windings, there may also be magnetic columns without windings. This case does not limit whether to provide magnetic columns without windings, and the number and position of magnetic columns without windings.

[0126] In an exemplary embodiment, if Figure 1D As shown, the rectifier board 120 includes: a circuit board 121 and a plurality of switch element groups 122, wherein the switch element groups 122 are as shown in FIG. Figure 1D The plurality of switch element groups 122 are disposed on the circuit board 121. The plurality of switch element groups 122 are arranged along the first direction X and are used to rectify the output current of the second winding 112. Each switch element group 122 includes at least one switch element 1221.

[0127] Among them, each switch element 1221 in the same switch element group 122 is arranged along the second direction Y. Also along the second direction Y, the comb teeth 1121A are adjacent to the switch element 1221. On the circuit board 121, a first line P is arranged along the first direction X, and a second line Q is arranged along the second direction Y. At least part of the second line Q is formed between the combs 1121B that are relatively arranged in the second winding 112. The first line P and the second line Q are electrically connected to the part of the switch elements 1221 respectively, wherein the potential at the connection point between the first line P or the second line Q and the switch element is the same, and part of the switch elements 1221 are connected to form a rectifier circuit. The first direction X and the second direction Y are perpendicular to each other. It should be noted that the so-called "a and b are arranged along the first direction", "a and b are arranged along the second direction", etc. does not mean that a and b must be arranged in a straight line. Due to the needs of the process or actual manufacturing, when a and b are arranged along a certain direction, the two may have a certain deviation or misalignment in the same direction, and the present case is not limited to this. Figure 3F The comb teeth 3121A arranged along the first direction on the circuit board shown in the figure are not arranged in a straight line between adjacent comb teeth 3121A, but are offset to a certain extent. Similarly, "a and b are arranged along the first direction" and "a and b are arranged along the second direction" can also mean that a and b overlap or do not overlap in a certain direction, such as Figure 1D The non-overlapping case is shown. Figure 3D and 3D-1 For overlapping situations.

[0128] In some embodiments of the present invention, along the second direction Y, the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112 are adjacent to the switch elements 1221 of the switch element group 122, and the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112 are on the same side or different sides of the switch elements 1221 in the same row in the switch element group 122 along the first direction X. Among them, at least one switch element 1221 may be included between the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112, such as Figure 1D , 1D-1 Along the second direction Y, the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112 are arranged in the same gap. The gap here refers to the gap between the switch elements 1221 in different rows in the switch element group 122 or the gap between the switch element 1221 and the edge of the rectifier plate 120, that is, the switch element 1221 may not be arranged between the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112. Figure 1D-3 shown.

[0129] In an exemplary embodiment, if Figure 1D As shown, the rectifier board 120 is provided with a first line P along the first direction X, and a second line Q along the second direction Y; the first line P and the second line Q are electrically connected to part of the switching elements, respectively. It should be noted that the figure only schematically shows a first line P and a second line Q. In fact, it can be understood that the first line P and the second line Q can be set between different switching tubes, wherein the first line P can be used as a power path, and the second line Q can be used as a harmonic path. Because of the existence of the second line Q, harmonics can have multiple paths to flow, thereby reducing the influence of the proximity effect between the lines, reducing the current loss on the rectifier board, and improving the overall power supply efficiency. As shown Figures 1A-1D As shown, the second line Q is formed between two comb spaces 1121B arranged opposite to each other along the second direction Y.

[0130] In an exemplary embodiment, if Figure 1DAs shown, any of the switch element groups 122 includes four switch elements 1221, namely a first switch element 1221A, a second switch element 1221B, a third switch element 1221C and a fourth switch element 1221D. The first switch element 1221A, the second switch element 1221B, the third switch element 1221C and the fourth switch element 1221D are arranged along the second direction Y. The two comb teeth 1121A of the comb-type pins 1121 are arranged on opposite sides of the second winding 112, and are respectively arranged between the first switch element 1221A and the second switch element 1221B, and between the third switch element 1221C and the fourth switch element 1221D. The second winding 112 inputs the alternating current into the rectifier circuit formed by the switch element group 122 through the two correspondingly arranged comb teeth 1121A for rectification. The so-called corresponding arrangement means that in space, multiple comb teeth between the same or different windings correspond one to one, such as Figure 1B and 1D As shown in FIG6A , the pins 1121 of the same second winding 112, along the second direction Y, the adjacent comb teeth of the same switch element group correspond to each other, as shown in FIG6B , the comb teeth of different first sub-windings 612A and second sub-windings 612B correspond to each other. Moreover, due to process or actual manufacturing requirements, the so-called corresponding arrangement of comb teeth does not mean that the corresponding comb teeth must be aligned, and the corresponding comb teeth may also be misaligned to a certain extent, such as Figure 2C As shown, the present invention is not limited thereto. In other embodiments of the present invention, as Figure 1D-3 As shown, any of the switch element groups 122 includes four switch elements 1221, namely a first switch element 1221A, a second switch element 1221B, a third switch element 1221C and a fourth switch element 1221D. The first switch element 1221A, the second switch element 1221B, the third switch element 1221C and the fourth switch element 1221D are arranged along the second direction Y. The two comb teeth 1121A of the comb-type pins 1121 arranged on opposite sides of the second winding 112 are both arranged between the second switch element 1221B and the third switch element 1221C. Of course, the present case is not limited to this, and the two comb teeth 1121A of the comb-type pins 1121 arranged on opposite sides of the second winding 112 can also be arranged between other different switch elements 1221 or between the gaps between the switch element 1221 and the edge of the rectifier plate 120.

[0131] In an exemplary embodiment, if Figure 1DAs shown, each switch element 1221 in the switch element group 122 is formed into a rectifier circuit by the first line P and the second line Q according to the bridge rectifier circuit. The four switches of the same switch element group 122 constitute a switch unit of a full-bridge rectifier circuit. Among them, the bridge rectifier circuit is a rectifier circuit well known to those skilled in the art, and its specific circuit structure is not described in detail here. Those skilled in the art use other rectifier circuit structures well known in the art to connect the circuit of the switch element group 122, which should also be within the scope of protection of the present disclosure.

[0132] Figure 1D-1 and Figure 1D The difference between the illustrated embodiments is that the positions of the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112 are different, wherein along the second direction Y, there is only one switch element 1221 between the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112 . Figure 1D-2 and Figure 1D The difference between the illustrated embodiments is that the positions of the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112 are different, wherein along the second direction Y, there are three switch elements 1221 between the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112. In other embodiments of the present case, along the second direction Y, the number of switch elements 1221 between the comb teeth 1121A of the comb-type pins 1121 on both sides of the second winding 112 can be flexibly adjusted according to actual needs.

[0133] In an exemplary embodiment, along the first direction X, at least one row of the switch elements 1221 (eg Figure 1D The first switch element 1221A shown is directly electrically connected to the comb-type pin 1121. That is, the switch element 1221 and the comb-type pin 1121 can be directly electrically connected without passing through other components such as capacitors and resistors.

[0134] In an exemplary embodiment, the plurality of switch element groups 122 may be electrically connected in series or in parallel on the circuit board 121. Some switch elements of each switch element group 122 are also electrically connected through the first line P and the second line Q, wherein the potential at the connection point between the first line P or the second line Q and the switch element is the same.

[0135] Figure 1F 1 is an assembly diagram of a rectifier module according to Embodiment 1 of the present disclosure. Figure 1F-1 1 is a schematic diagram of a rectifier board structure of a rectifier module of the first embodiment of the present disclosure. The transformer 110 and the rectifier board 120 are assembled into the rectifier module 100 as shown in the figure. Among them, each switch element group 122 is located on a side close to the transformer 110, such as Figure 1F-1 shown.

[0136] In an exemplary embodiment, at least one output capacitor group 125 is further provided on the circuit board 121. Figure 1F As shown in the dotted box. The output capacitor groups 125 are arranged along the second direction Y. The output capacitor group 125 includes a plurality of output capacitors. The output capacitors in the same output capacitor group 125 are arranged along the first direction X. The switch element groups 122 are connected to the output terminal through the output capacitor group 125, and the rectified current is output to the load through the output terminal.

[0137] In an exemplary embodiment, the circuit board 121 includes at least two output capacitor groups 125 on one side where the switch element group 122 is provided, wherein along the second direction Y, the at least two output capacitor groups 125 are adjacent to the switch element 1221 of the switch element group 122. It should be understood that the at least two output capacitor groups 125 can be arranged together between two rows of switch elements, or respectively adjacent to switch elements in different rows. Figure 1F-1 As shown, at least two output capacitor groups 125 include two rows of switch elements 1221. In other embodiments of the present invention, at least two output capacitor groups 125 may not include switch elements 1221, or may include one row, three rows, four rows, etc. of switch elements 1221, and the present invention is not limited thereto. In addition, usually, one side of the circuit board 121 where the switch element group 122 is not provided will also be provided with an output capacitor group 125 corresponding to the other side. It should be understood that the position of the output capacitor group is not limited thereto. In other embodiments, the output capacitor groups provided on the circuit board 121 may also be arranged entirely on the side where the switch element group 122 is not provided.

[0138] In an exemplary embodiment, if Figure 1D As shown, a plurality of driving resistors 1222 are also provided on the circuit board 121. The plurality of driving resistors 1222 are adjacent to the corresponding switch elements 1221, and are used to turn on the corresponding switch elements 1221. The plurality of driving resistors 1222 are arranged along the first direction X or the second direction Y. In this embodiment, the driving resistors 1222 and the switch elements 1221 correspond one to one, and in other embodiments of the present case, one driving resistor 1222 can be connected to a plurality of switch elements 1221, and the present case is not limited thereto.

[0139] In an exemplary embodiment, if Figure 1G As shown, an output terminal 123 is also provided on the circuit board 121. The rectifier board 120 is connected to the output terminal 123 through the conductive sheet 124, thereby being electrically connected to an external device. Therefore, the AC power output by the transformer 110 in the present disclosure does not need to be transmitted to the external device through the main board 127 after being rectified by the switch element group 122. Figure 1G-11 is a schematic diagram of a partial cross-section of the conductive sheet 124 of this embodiment. As shown in the dotted frame portion, the conductive sheet 124 is directly electrically connected to the output terminal 123. The design of the output terminal 123 shortens the transmission path of the high-current output signal, effectively reducing the energy loss of the output signal during transmission. In some embodiments of the present case, the conductive sheet 124 can be a copper busbar. The structure of the conductive sheet 124 connected between the rectifier plate 120 and the output terminal 123 can be implemented in many ways. Figure 1G The structure provided is a schematic implementation structure. A person skilled in the art can design a structure of the conductive sheet 124 that matches the actual structural requirements, which should be considered within the protection scope of the present disclosure.

[0140] It should be understood that Figure 1G In the embodiment, there are two rectifier plates 120, which are respectively arranged on both sides of the transformer 110 and are perpendicular to the main board 127. In some other embodiments of the present application, there may be only one rectifier plate 120, and at least a part of the rectifier plate 120 is arranged below the transformer 110. Furthermore, the main board 127 and the rectifier plate 120 may be integrally formed, that is, the main board 127 and the rectifier plate 120 are the same plate, and the rectifier plate 120 is an area on the main board 127.

[0141] The rectifier module and transformer provided by the embodiments of the present disclosure are designed to be comb-type pins by connecting the second winding to the rectifier board. The comb-type pins include a plurality of comb teeth and comb spaces arranged adjacent to the comb teeth. The comb teeth are arranged along a first direction. At the same time, in conjunction with the circuit design of the switch element group of the rectifier board, the switch elements of the same switch element group are arranged along a second direction perpendicular to the direction of the comb teeth. This forms a first line P along the first direction and a second line Q along the second direction on the rectifier board. By leaving gaps between the switch elements of adjacent switch element groups, a path is provided for alternating current, thereby reducing the influence of the proximity effect between the lines, reducing the current loss on the rectifier board, and improving the overall power supply efficiency.

[0142] Embodiment 2

[0143] See also Figure 2A , 2B and 2C, Figure 2A is a structural diagram of a rectifier module according to the second embodiment of the present disclosure, Figure 2B It is a schematic diagram of the structure of the transformer of the second embodiment of the present disclosure. Figure 2C 1 is a schematic diagram of the structure of the rectifier board of the second embodiment of the present disclosure. The difference between the second embodiment and the first embodiment is the structure of the second winding of the transformer. The other parts are similar to the first embodiment and will not be repeated here.

[0144] like Figure 2AAs shown, the rectifier module 200 includes: a transformer 210 and a rectifier plate 220. Among them, the transformer 210 includes: a magnetic core 213, a first winding 211 and a second winding 212. The rectifier plate 220 is a circuit board including a plurality of switch element groups. The rectifier plate 220 is electrically connected to the transformer 210. It should be noted that, for the sake of simplicity, the switch elements on the rectifier plate 220 are not shown in the figure, and the rectifier plate 220 here is only used for illustration. In addition, in other embodiments of the present case, a substrate (not shown in the figure) can also be arranged between the transformer 210 and the rectifier plate 220, and a through hole is reserved on the substrate for the comb-type pins of the second winding 212 to pass through, so as to fix the second winding 212.

[0145] like Figure 2B As shown, the transformer 210 includes: a magnetic core 213, a first winding 211 and a second winding 212. The first winding 211 is composed of a coil for receiving input alternating current. The magnetic core 213 includes a magnetic column, and the coil constituting the first winding 211 is arranged on the magnetic column, and the magnetic core 213 mainly plays a magnetic conductive role. The second winding 212 is a coil group composed of multiple coils in parallel. Each coil has two side pins arranged oppositely. The two side pins of each parallel coil respectively constitute the comb pins 2121 of the second winding 212 (as shown in the dotted box in the figure). The comb pins 2121 of each coil are arranged along the first direction X. The transformer 210 is electrically connected to the rectifier plate 220 through the comb pins 2121. In other embodiments of the present case, the multiple coils of the second winding 212 can also be connected in series to form a coil group, and the present case is not limited to this.

[0146] The so-called corresponding arrangement refers to a one-to-one correspondence between multiple comb teeth of the same or different windings in space, for example, a corresponding arrangement along the second direction Y. However, due to process or actual manufacturing requirements, the so-called corresponding arrangement of comb teeth does not mean that the corresponding comb teeth must be flush, such as Figure 2C As shown, since the coil constituting the second winding 212 is a multi-turn coil, its two pins 2121A are offset to a certain extent along the first direction X. Therefore, the second line Q (not shown in the figure) arranged along the second direction Y is not necessarily parallel to the second direction Y, and it only needs to be formed between the oppositely arranged combs of the second winding 212.

Among them, the transformer 310 includes: a magnetic core 313, a first winding 311 and a second winding 312. The rectifier plate 320 is a circuit board including a plurality of switch element groups. The rectifier plate 320 is electrically connected to the transformer 310. It should be noted that, for the sake of simplicity, the switch elements on the rectifier plate 320 are not shown in the figure, and the rectifier plate 320 here is only used as a schematic. In addition, in other embodiments of the present case, a substrate (not shown in the figure) can also be arranged between the transformer 310 and the rectifier plate 320, and a through hole is reserved on the substrate for the comb-type pins of the second winding 312 to pass through, so as to fix the second winding 312. Figure 3F 3 is an assembly diagram of a rectifier module according to the third embodiment of the present disclosure. The transformer 310 and the rectifier board 320 are assembled into the rectifier module 300 as shown in the figure.

[0150] like Figure 3B and 3CAs shown, the transformer 310 includes: a magnetic core 313, a first winding 311 and a second winding 312. The first winding 311 is composed of a coil and is used to receive input alternating current. The magnetic core 313 includes a magnetic column, and the coil constituting the first winding 311 is arranged on the magnetic column. The magnetic core 313 mainly plays a magnetic conduction role. The second winding 312 includes a first sub-winding 312A and a second sub-winding 312B. The first sub-winding 312A is arranged outside the first winding 311. The second sub-winding 312B is arranged outside the first sub-winding 312A. The comb-type pins 3121 of the second winding 312 are respectively arranged on opposite sides of the first sub-winding 312A and the second sub-winding 312B. The comb-type pins 3121 include comb teeth 3121A and comb spaces 3121B arranged adjacent to the comb teeth 3121A. The comb-type pins 3121 are arranged along the first direction X. Taking the first sub-winding 321A as an example, the comb-type leg 3121 includes at least two comb teeth 3121A', and a comb space 3121B' is arranged adjacent to the comb teeth 3121A'.

[0201] like Fig. 10AIn the illustrated embodiment, the second winding 1012 includes a first separate winding 1012A and a second separate winding 1012B, wherein the first separate winding 1012A and the second separate winding 1012B both include comb-type pins, and the comb-type pins of the first separate winding 1012A and the second separate winding 1012B have different directions. Correspondingly, the rectifier plate 1020 includes a first separate rectifier plate 1020A and a second separate rectifier plate 1020B, wherein the comb-type pins of the first separate winding 1012A are disposed on the first shunt rectifier plate 1020A, and the comb-type pins of the second separate winding 1012B are disposed on the second shunt rectifier plate 1020B. It should be noted that the first separate winding 1012A and the second separate winding 1012B, the first separate rectifier plate 1020A and the second separate rectifier plate 1020B in this embodiment are different from the first winding 511, the second winding 512, the first circuit board 521A and the second circuit board 521B in the fifth embodiment.

[0202] In some embodiments of the present case, the first separate winding 1012A and / or the second separate winding 1012B may also be configured in the form of the second winding 912 in Embodiment 9, such as Fig. 10B and 10C As shown, no further details are given here.

[0203] Embodiment 11

[0204] See also Fig.11 , Fig.11 1 is a schematic diagram of the structure of a transformer according to the eleventh embodiment of the present disclosure. The difference between the eleventh embodiment and the first embodiment is the second winding of the transformer.

[0205] like Fig.11As shown, the transformer 1110 includes: a magnetic core 1113, a first winding 1111 and a second winding 1112. The first winding 1111 is composed of a coil for receiving input alternating current. The magnetic core 1113 includes a magnetic column, and the coil constituting the first winding 1111 is arranged on the magnetic column. The magnetic core 1113 mainly plays a magnetic conductive role. The second winding 1112 is arranged on the outside of the first winding 1111. Rows of first pins 1130 and 1140 are respectively arranged on opposite sides of the second winding 1112. The first pin 1130 and the second pin 1140 are arranged on the circuit board in a surface mounting manner. Along the second direction Y, the first pin 1130 and the second pin 1140 are adjacent to the switching element; the first direction X and the second direction Y are perpendicular to each other. It should be understood that Fig.11 The specific distribution mode of the first pin and the second pin of the transformer and the switch element is the same as that of the comb-type pins in the above embodiment, and will not be described in detail here.

[0206] In addition, it can be seen that Fig.11 The second winding 1112 and Fig. 1I The second winding 112 shown differs in that Fig.11 The pins of the second winding 1112 are not comb-shaped pins, and the first pin 1130 and the second pin 1140 are respectively arranged in a row. Fig. 1I The effect achieved by the embodiment shown is similar. That is, by arranging the first pin 1130 and the second pin 1140 connecting the second winding 1112 to the rectifier board on the circuit board in a surface mount manner, the first pin 1130 and the second pin 1140 of the second winding 1112 are prevented from blocking the AC path as a whole, so that the gap between the switching elements can provide a path for the AC, that is, multiple second lines can be formed in the second direction of the circuit board, so that harmonics can flow through multiple paths, thereby reducing the influence of the proximity effect between the lines, reducing the current loss on the rectifier board, and improving the overall power supply efficiency.

[0207] In some embodiments of the present invention, along the first direction X, the lengths of the first pin 1130 and the second pin 1140 are greater than the length of at least one switch element.

[0208] In some embodiments of the present invention, along the first direction X, the first pin 1130 and the second pin 1140 have the same length.

Similarly, the second winding can also be disposed on the outside of the first winding through the skeleton, and the present case is not limited thereto.

[0211] In some embodiments of the present case, the circuit board may be a multi-layer circuit board, and the switch element may be disposed on the topmost and / or bottommost circuit board, but the present case is not limited thereto.

Among them, the bridge rectifier circuit and the center-pull rectifier circuit are rectifier circuits well known to those skilled in the art, and their specific circuit structures are not described in detail here. Those skilled in the art use other rectifier circuit structures well known in the art to perform circuit connection of the switch element group, which should also be within the scope of protection of the present disclosure.

[0213] In some embodiments of the present invention, the second winding is a metal sheet or a PCB winding. The PCB winding can be a flexible PCB winding or a rigid PCB winding. Figure 1B In the embodiment shown, the second winding 112 may also be a flexible PCB winding. Figure 1C In the illustrated embodiment, the second winding 112 may also be a rigid PCB winding.

[0214] In some embodiments of the present invention, along the first direction X, at least one row of switch elements (eg Figure 1D The first switch element 1221A) shown in the figure is directly electrically connected to the comb-type pins, that is, the switch element and the comb-type pins can be directly electrically connected without passing through other components such as capacitors and resistors.

[0215] In some embodiments of the present case, on a circuit board, a plurality of switch element groups may be electrically connected in series or in parallel, wherein each switch element group is also electrically connected via the aforementioned first circuit and second circuit.

[0216] In some embodiments of the present case, an output terminal is also provided on the circuit board. The rectifier board is connected to the output terminal through a copper busbar, thereby being electrically connected to an external device. As a result, the alternating current output by the transformer in the present disclosure does not need to be transmitted to the external device through the system board after being rectified by the switch element group. Through the design of the output terminal, the transmission path of the high-current output signal is shortened, and the energy loss of the output signal during the transmission process is effectively reduced.

[0217] In some embodiments of the present case, the comb-type pins and the rectifier plate can be welded by via holes or surface mounting.

[0218] In some embodiments of the present case, along the second direction Y, at least a portion of the second line Q is formed between the relatively arranged combs of the second winding, the second line Q is arranged on the circuit board, and the second line Q is used to provide a path for harmonics.

Specifically, the metal sheet includes an iron sheet, a copper sheet, an aluminum sheet, a nickel sheet, a tungsten sheet, a molybdenum sheet, a cobalt sheet, etc., and also includes metal sheets made of various metal alloys, including stainless steel sheets, nickel-based alloy sheets, copper alloy sheets, and aluminum alloy sheets, etc. The PCB winding may be a flexible PCB winding or a rigid PCB winding.

[0220] In some embodiments of the present case, distributed air gaps are provided on the transformer. The distributed air gaps can be provided on the magnetic columns, for example, and the distributed air gaps can also be filled with non-conductive and non-magnetic air gap forming materials, or filled with air gap forming materials with low magnetic permeability.

[0221] The rectifier module and transformer provided by the embodiments of the present disclosure are designed to be comb-type pins by designing the pins connecting the second winding to the rectifier board, and the comb-type pins include a plurality of comb teeth and comb spaces arranged adjacent to the comb teeth. The comb teeth are arranged along a first direction. At the same time, in conjunction with the circuit design of the switch element group of the rectifier board, the switch elements of the same switch element group are arranged along a second direction perpendicular to the direction of the comb teeth. There are gaps between the switch elements, and the gaps can provide a path for alternating current, that is, multiple second lines can be formed in the second direction of the circuit board, so that harmonics have multiple paths to flow, thereby reducing the influence of the proximity effect between the lines, reducing the current loss on the rectifier board, and improving the overall power supply efficiency.
