The entire content of the Chinese patent applications is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure relates to the field of power electronics technology, and more particularly, to a rectifier module and a transformer. Background Art

[0004] With the improvement of human requirements for intelligent life, the social demand for data processing is increasing day by day. The energy consumption for global data processing reaches hundreds of billions or even trillions of degrees annually on average; and the floor area of a large data center can reach tens of thousands of square meters. Therefore, high efficiency and high power density are the key indicators for the healthy development of this industry.

[0005] As the integration degree of electrical equipment per unit volume continues to increase, the power supply for these electrical equipment is expected to have higher efficiency, higher power density, and smaller volume to support the overall power consumption requirements. 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 large-current windings becomes increasingly important. The form of the windings should not only match the placement of the secondary rectifier tubes 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 alternating current in two conductors approaches the adjacent conductor. The proximity effect problem will cause the resistance of adjacent transmission lines to increase, thereby increasing the power loss on the lines and affecting the power supply efficiency. Therefore, for a low-voltage high-current transformer, the design of its rectifier board is also particularly important. Poor design will result in excessive loss, low efficiency, and excessive heating of the rectifier board, posing a safety hazard.

[0007] However, in the prior art, there is still a lack of targeted solutions to the proximity effect problems existing in the transformers and rectifier boards of power supplies. Therefore, how to design the transformers and rectifier boards to avoid the proximity effect problems and improve the power supply efficiency of the power supply has become an urgent technical problem in this field.

[0117] As Figure 1A As shown, the rectification module 100 includes: a transformer 110 and a rectification plate 120. Among them, the transformer 110 includes: a magnetic core 113, a first winding 111 and a second winding 112. Among them, the transformer 110 changes the AC voltage through the first winding 111 and the second winding 112. The rectification plate 120 is a circuit board including a plurality of switch element groups ( Figure 1A not shown in the figure). The rectification plate 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 simplicity, the switch elements on the rectification plate 120 are not shown in the figure, and the rectification plate 120 here is only for illustration. In addition, in other embodiments of this case, a substrate (not shown in the figure) may be provided between the transformer 110 and the rectification plate 120, and through holes for the comb-shaped leads of the second winding 112 to pass through are reserved on the substrate for fixing the second winding 112.

[0118] As 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 coils and is used to connect to the input alternating current. The magnetic core 113 includes magnetic posts 118, and the coils constituting the first winding 111 are arranged on the magnetic posts 118. The magnetic core 113 mainly functions as a magnetic conductor. The second winding 112 is arranged outside the first winding 111 and is used to electrically connect to a rectifying plate 120 to input the alternating current output by the transformer 110 into the rectifying plate 120 for rectification. Comb-shaped pins 1121 are respectively arranged on opposite sides of the second winding 112. The comb-shaped pins 1121 are arranged along the first direction X. The comb-shaped pins 1121 include at least two comb teeth 1121A, and there are comb intervals 1121B adjacent to the comb teeth 1121A. The comb-shaped pins 1121 are formed by alternating multiple comb teeth 1121A and comb intervals 1121B, presenting a comb-shaped structure. The transformer 110 is electrically connected to the rectifying plate 120 through the comb teeth 1121A. It should be noted that the shape of the comb-shaped pins 1121 shown in the figure is only an example. In other embodiments, the shape of the comb-shaped pins 1121 is not limited, and as long as it can be electrically connected, it should be considered within the protection scope of this case. In some embodiments of this case, the magnetic posts 118 are cylindrical, and the axial direction of the magnetic posts 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 shown are the opposite sides along the second direction Y, Figure 5A and the opposite sides of the second winding 512 shown are the opposite sides along the third direction Z.

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

[0121] In an exemplary embodiment, the second winding 112 can 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, and 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, etc. The PCB winding can be a flexible PCB winding or a rigid PCB winding. For example, in Figure 1B the embodiment shown, the second winding 112 can also be a flexible PCB winding, so as to be bent into a U-shaped winding. And in an embodiment such as Figure 1C shown, the second winding 112 can also be a rigid PCB winding. The Figure 1CIn the illustrated embodiment, except for the different materials used for the second winding 112, other parts have the same structure as the previous embodiment and will not be elaborated here.

[0122] In an exemplary embodiment, as Figure 1B shown, the comb-shaped lead 1121 and the rectifying plate 120 can be welded through vias. In other embodiments of this case, as Figure 1I shown, the comb-shaped lead 1121 and the rectifying 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 this 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, as Figure 1A and 1C shown.

[0124] In some embodiments of this case, as Figure 1B and Figure 1H shown, the magnetic post 118 extends along the first direction X, and the second winding 112 includes a main body portion 1122 (such as Figure 1B shown by the dashed box in Figure 1B and 1H ), and a comb-shaped lead 1121 (such as Figure 5A and 6A shown by the dashed box). The main body portion 1122 includes a first end 1122A and a second end 1122B oppositely arranged along the first direction X, and a third end 1122C and a fourth end 1122D oppositely arranged. Among them, the comb-shaped lead 1121 is connected to the third end 1122C and the fourth end 1122D, and the main body portion 1122 extends along the first direction. That is, the extending direction of the main body portion 1122 of the second winding 112 is the same as the extending direction of the magnetic post 118. In an exemplary embodiment, the second winding 112 is integrally formed. In other embodiments of this case, the second winding 112 may include multiple sub-windings. Among them, each sub-winding may include a comb-shaped lead, and each sub-winding may also be integrally formed. At the same time, the arrangement manner of the sub-windings can also be diverse. For example, Figure 2A and 2B shown, the second winding is composed of multiple half-turn windings. In other embodiments of this case, among the multiple sub-windings forming the second winding, each sub-winding may not be a comb-shaped lead. For example, Figure 2A and 2B shown, the second winding is composed of multiple coils, and the leads on both sides of the coil group formed by the multiple coils are respectively comb-shaped leads.

[0125] In an exemplary embodiment, as Figure 1EAs shown, the magnetic core 113 includes at least two magnetic posts. Exemplarily, at least two magnetic posts of the magnetic core 113 are arranged along the second direction Y. The first winding 111 and the second winding 112 are both arranged on the at least two magnetic posts. It should be noted that the so-called magnetic posts herein refer to the magnetic posts on which windings are arranged. For example, in the embodiments shown in Figure 1A , 1B etc., in addition to the magnetic posts on which windings are arranged, there may also be magnetic posts on which no windings are arranged. This case does not limit whether there are magnetic posts on which no windings are arranged, as well as the number and positions of the magnetic posts on which no windings are arranged.

[0126] In an exemplary embodiment, as shown in Figure 1D , the rectifying plate 120 includes: a circuit board 121 and a plurality of switch element groups 122, where the switch element groups 122 are as shown in Figure 1D within the dashed box. The plurality of switch element groups 122 are arranged on the circuit board 121. The plurality of switch element groups 122 are arranged in a row 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, the switch elements 1221 in the same switch element group 122 are 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 opposing comb spaces 1121B of the second winding 112. The first line P and the second line Q are respectively electrically connected to some of the switch elements 1221. Among them, the potentials at the connection points of the first line P or the second line Q and the switch elements are the same, and some of the switch elements 1221 are connected to form a rectifying 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. do not mean that a and b must be arranged in a straight line. Due to process or actual manufacturing requirements, when a and b are arranged along a certain direction, there may be a certain deviation or misalignment between the two in the same direction, and this case is not limited thereto. For example, as shown in Figure 3F , the comb teeth 3121A arranged along the first direction on the circuit board shown are not arranged in a straight line, and there is a certain misalignment between adjacent comb teeth 3121A. Similarly, "a and b are arranged along the first direction", "a and b are arranged along the second direction" can also mean that a and b overlap or do not overlap along a certain direction. For example, as shown in Figure 1D is the case of non-overlap, and as shown in Figure 3D and 3D-1 are the cases of overlap.

[0128] In some embodiments of the present case, along the second direction Y, the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112 are adjacent to the switching elements 1221 of the switching element group 122, and the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112 are on the same side or different sides of the same row of switching elements 1221 in the switching element group 122 along the first direction X. Among them, there may be at least one switching element 1221 between the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112, such as Figure 1D , 1D-1 as shown in FIG. 1D-2. Along the second direction Y, the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112 are arranged in the same gap. The gap mentioned here refers to the gap between different rows of switching elements 1221 in the switching element group 122 or the gap between the switching element 1221 and the edge of the rectifying plate 120. That is, there may be no switching element 1221 between the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112, such as Figure 1D - 3 shown in FIG.

[0129] In an exemplary embodiment, as Figure 1D shown, the rectifying plate 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 respectively electrically connected to some of the switching elements. It should be noted that only one first line P and one second line Q are schematically drawn in the figure. In fact, it can be understood that the first line P and the second line Q can be provided between different switching tubes. Among them, 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, the harmonics can flow through multiple paths, thereby reducing the influence of the proximity effect between the lines, reducing the current loss on the rectifying plate, and improving the overall power supply efficiency. As Figure 1A - 1D shown, the second line Q is formed between two comb spaces 1121B arranged oppositely along the second direction Y.

[0130] In an exemplary embodiment, as Figure 1DAs shown, any one 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. Two comb teeth 1121A of the comb-shaped pins 1121 provided on opposite sides of the second winding 112 are respectively disposed 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 an alternating current into the rectification 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 terms of space, multiple comb teeth between the same or different windings correspond one by one, such as Figure 1B and 1D shown, for 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 6B, the comb teeth of different first sub-windings 612A and second sub-windings 612B correspond to each other. And due to process or actual manufacturing requirements, the so-called corresponding arrangement of the comb teeth does not mean that the corresponding comb teeth must be flush, and there can also be a certain misalignment between the corresponding comb teeth, such as Figure 2C shown, and this case is not limited thereto. In other embodiments of this case, such as Figure 1D - 3 shown, any one 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. Two comb teeth 1121A of the comb-shaped pins 1121 provided on opposite sides of the second winding 112 are both disposed between the second switch element 1221B and the third switch element 1221C. Of course, this case is not limited thereto, and the two comb teeth 1121A of the comb-shaped pins 1121 provided on opposite sides of the second winding 112 can also be disposed between other different switch elements 1221 or in the gap between the switch element 1221 and the edge of the rectification plate 120.

[0131] In an exemplary embodiment, such as Figure 1DAs shown, each switching element 1221 in the switching element group 122 forms a rectifier circuit with the first line P and the second line Q according to a bridge rectifier circuit. Four switches of the same switching element group 122 constitute a switching 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 will not be elaborated here. Those skilled in the art using other rectifier circuit structures well-known in the art to connect the circuit of the switching element group 122 should also be within the protection scope of this disclosure.

[0132] Figure 1D - 1 and Figure 1D The difference from the embodiment shown is that the positions of the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112 are different. Among them, along the second direction Y, there is only one switching element 1221 between the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112. Figure 1D - 2 and Figure 1D The difference from the embodiment shown is that the positions of the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112 are different. Among them, along the second direction Y, there are three switching elements 1221 between the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112. In other embodiments of this case, the number of switching elements 1221 between the teeth 1121A of the comb-shaped leads 1121 on both sides of the second winding 112 along the second direction Y can be flexibly adjusted according to actual needs.

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

[0134] In an exemplary embodiment, on the circuit board 121, the multiple switching element groups 122 can be electrically connected in series or in parallel. Some of the switching elements of each switching element group 122 are also electrically connected through the aforementioned first line P and second line Q. Among them, the potentials at the connection points of the first line P or the second line Q and the switching elements are the same.

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

[0136] In an exemplary embodiment, at least one output capacitor bank 125 is further provided on the circuit board 121, as Figure 1F shown by the dashed box. The output capacitor banks 125 are arranged along the second direction Y. Inside the output capacitor bank 125, a plurality of output capacitors are included. The output capacitors within the same output capacitor bank 125 are arranged along the first direction X. The switch element groups 122 are connected to the output terminals through the output capacitor bank 125, and the rectified current is output to the load through the output terminals.

[0137] In an exemplary embodiment, on the surface of the circuit board 121 where the switch element group 122 is provided, at least two output capacitor banks 125 are included. Among them, along the second direction Y, at least two output capacitor banks 125 are adjacent to the switch elements 1221 of the switch element group 122. It should be understood that at least two output capacitor banks 125 can be arranged together between two rows of switch elements, or respectively adjacent to the switch elements in different rows. As Figure 1F - 1 shown, two rows of switch elements 1221 are included between at least two output capacitor banks 125. In other embodiments of this case, at least two output capacitor banks 125 may not include switch elements 1221, or may include one row, three rows, four rows, etc. of switch elements 1221. This case is not limited thereto. In addition, usually on the surface of the circuit board 121 where the switch element group 122 is not provided, output capacitor banks 125 corresponding to the other surface are also provided. It should be understood that the position of the output capacitor bank is not limited thereto. In other embodiments, the output capacitor banks provided on the circuit board 121 can also be all arranged on the surface where the switch element group 122 is not provided.

[0138] In an exemplary embodiment, as Figure 1D shown, a plurality of driving resistors 1222 are further 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 are in one-to-one correspondence. In other embodiments of this case, one driving resistor 1222 can be connected to a plurality of switch elements 1221. This case is not limited thereto.

[0139] In an exemplary embodiment, as Figure 1G shown, an output terminal 123 is further provided on the circuit board 121. The rectifying board 120 is connected to the output terminal 123 through a conductive sheet 124, so as to be electrically connected to an external device. Thus, the alternating current 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 - 1It is a schematic structural diagram of a partial cross-section of the conductive sheet 124 in this embodiment. As shown in the dashed box in the figure, the conductive sheet 124 is directly electrically connected to the output terminal 123. Through the design of this output terminal 123, the transmission path of the output signal of the large current is shortened, and the energy loss of the output signal during transmission is effectively reduced. In some embodiments of this case, the conductive sheet 124 can be a copper busbar. There can be many implementation manners for the structure of the conductive sheet 124 connected between the rectifying plate 120 and the output terminal 123. The above Figure 1G shows a schematic implementation structure. Those skilled in the art should consider the structures of the conductive sheet 124 designed according to actual structural requirements to be within the protection scope of this disclosure.

[0140] It should be understood that Figure 1G in, there are two rectifying 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 this application, there can also be only one rectifying plate 120, and at least a part of the rectifying plate 120 is arranged below the transformer 110. Further, the main board 127 and the rectifying plate 120 can be integrally formed, that is, the main board 127 and the rectifying plate 120 are the same board, and the rectifying plate 120 is an area on the main board 127.

[0141] For the rectifying module and the transformer provided by the embodiments of this disclosure, by designing the lead-out pins connecting the second winding and the rectifying plate as comb-shaped lead-out pins, the comb-shaped lead-out pins include a plurality of comb teeth and combs adjacent to the comb teeth. The comb teeth are arranged along the first direction. At the same time, in cooperation with the circuit design of the switching element group on the rectifying plate, the respective switching elements of the same switching element group are arranged along the second direction perpendicular to the comb teeth direction. This forms a first line P along the first direction and a second line Q along the second direction on the rectifying plate. By leaving a gap between the switching elements of adjacent switching element groups, a path is provided for the alternating current, thereby reducing the proximity effect between the lines, reducing the current loss on the rectifying plate, and improving the overall power supply efficiency.

[0142] Embodiment 2

[0143] See Figure 2A 、 2B and 2C, Figure 2A which is a schematic structural diagram of the rectifying module of the second embodiment of this disclosure, Figure 2B which is a schematic structural diagram of the transformer of the second embodiment of this disclosure. Figure 2C which is a schematic structural diagram of the rectifying plate of the second embodiment of this disclosure. The difference between this second embodiment and the foregoing first embodiment lies in the structure of the second winding of the transformer. Other parts are similar to those in the first embodiment and will not be repeated here.

[0144] As Figure 2AAs shown, the rectification module 200 includes a transformer 210 and a rectification board 220. Among them, the transformer 210 includes a magnetic core 213, a first winding 211, and a second winding 212. The rectification board 220 is a circuit board including a plurality of switch element groups. The rectification board 220 is electrically connected to the transformer 210. It should be noted that, for simplicity, the switch elements on the rectification board 220 are not shown in the figure, and the rectification board 220 here is only for illustration. Additionally, in other embodiments of this case, a substrate (not shown in the figure) may be provided between the transformer 210 and the rectification board 220, and through holes for the comb-shaped leads of the second winding 212 to pass through are reserved on the substrate for fixing the second winding 212.

[0145] As Figure 2B 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 coils and is used to access the input alternating current. The magnetic core 213 includes magnetic columns, and the coils constituting the first winding 211 are arranged on the magnetic columns. The magnetic core 213 mainly plays a role in guiding magnetic flux. The second winding 212 is a coil group composed of a plurality of coils connected in parallel. Each coil has two opposite side leads. The two side leads of each parallel coil respectively constitute the comb-shaped leads 2121 of the second winding 212 (as shown by the dashed box in the figure). The comb-shaped leads 2121 of each coil are arranged along the first direction X. The transformer 210 is electrically connected to the rectification board 220 through the comb-shaped leads 2121. In other embodiments of this case, the multiple coils of the second winding 212 may also be connected in series with each other to form a coil group, and this case is not limited thereto.

[0146] The so-called corresponding setting means that in space, multiple comb teeth between the same or different windings correspond one by one, for example, they are correspondingly arranged along the second direction Y. However, due to process or actual manufacturing requirements, the so-called comb tooth corresponding setting does not mean that the corresponding comb teeth must be flush, as Figure 2C shown. Since the coils constituting the second winding 212 are multi-turn coils, there is a certain displacement between its two leads 2121A 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, as long as it is formed between the relatively arranged combs of the second winding 212.

The difference between the third embodiment and the foregoing first embodiment lies in the structure of the second winding of the transformer and the layout structure of the switching element group in the corresponding rectifying plate. Other parts are similar to those in the first embodiment and will not be repeated here.

[0149] As Figure 3A shown, the rectifying module 300 includes: a transformer 310 and a rectifying plate 320. Among them, the transformer 310 includes: a magnetic core 313, a first winding 311, and a second winding 312. The rectifying plate 320 is a circuit board including a plurality of switching element groups. The rectifying plate 320 is electrically connected to the transformer 310. It should be noted that for simplicity, the switching elements on the rectifying plate 320 are not shown in the figure, and the rectifying plate 320 here is only used for illustration. Additionally, in other embodiments of this case, a substrate (not shown in the figure) may be provided between the transformer 310 and the rectifying plate 320, and through holes for the comb-shaped leads of the second winding 312 to pass through are reserved on the substrate for fixing the second winding 312. Figure 3F is a schematic assembly view of the rectifying module of the third embodiment of the present disclosure, and the transformer 310 and the rectifying plate 320 are assembled into the rectifying module 300 as shown.

[0150] As 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 coils and is used to connect to the input alternating current. The magnetic core 313 includes magnetic columns, and the coils constituting the first winding 311 are arranged on the magnetic columns. The magnetic core 313 mainly plays a role in guiding magnetic flux. 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. Comb-shaped leads 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-shaped lead 3121 includes comb teeth 3121A and combs 3121B adjacent to the comb teeth 3121A. The comb-shaped lead 3121 is arranged along the first direction X.

It should be noted here that the combs 3121B' are adjacent to the comb teeth 3121A', and the combs 3121B' are not necessarily between two comb teeth 3121A'. For example Figure 3B the comb teeth 3121A' and combs 3121B' at the edge of the comb-shaped lead in Figure 3B .

The comb teeth 3121A' of the first sub-winding 312A and the comb teeth 3121A'' of the second sub-winding 312B are arranged at intervals.

In addition to the above-mentioned first set of spaced-apart comb-shaped leads 4121, a second set of spaced-apart comb-shaped leads 4122 along the first direction X is formed between the first side and the second side of the second winding. Among them, the second set of spaced-apart comb-shaped leads 4122 may include two rows of comb-shaped leads along the second direction Y, or may be arranged only along the first direction X, as Figure 4C shown, but in fact, it has the same function as the two rows of comb-shaped leads and the same number of comb teeth, only the arrangement positions of the two rows of comb-shaped leads have a deviation in the second direction, as Figure 4CThe middle comb teeth 4122A include two types, diagonal shading and dotted-line shading, corresponding to two rows of comb-shaped pins respectively.

The so-called that the comb teeth 4122A in the second group of spaced-apart comb-shaped pins 4122 are arranged corresponding to the comb teeth 4121A in the first group of spaced-apart comb-shaped pins 4121 means that the comb teeth of one row of the first group of spaced-apart comb-shaped pins 4121 correspond to the comb teeth of one row of the second group of spaced-apart comb-shaped pins 4122, as Figure 4A - 4C shown. Among them, the second group of spaced-apart comb-shaped pins is used to form the center tap of the center-tapped rectifier transformer.

[0198] Embodiment Ten

[0199] See Figure 10A , 10B,Figure 10C , Figure 10A is a first schematic structural diagram of the rectification module according to Embodiment 10 of the present disclosure. Figure 10B is a second schematic structural diagram of the rectification module according to Embodiment 10 of the present disclosure. Figure 10C is a third schematic structural diagram of the rectification module according to Embodiment 10 of the present disclosure. The difference between Embodiment 10 and the foregoing Embodiment 1 lies in the structures of the second winding of the transformer and the rectification plate. Other parts are similar to those in Embodiment 1 and will not be repeated here.

[0200] As Figures 10A to 10C shown, the rectification module 1000 includes: a transformer 1010 and a rectification plate 1020. Among them, the transformer 1010 includes: a magnetic core 1013, a first winding 1011, and a second winding 1012. The rectification plate 1020 is a circuit board including a plurality of switch element groups. The rectification plate 1020 is electrically connected to the transformer 1010. It should be noted that, for simplicity, the switch elements on the rectification plate 1020 are not shown in the figure, and the rectification plate 1020 here is only used for illustration. In addition, in other embodiments of this case, a substrate (not shown in the figure) may be provided between the transformer 1010 and the rectification plate 1020, and through holes for the comb-shaped leads of the second winding 1012 to pass through are reserved on the substrate for fixing the second winding 1012.

[0201] As Figure 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. The first separate winding 1012A and the second separate winding 1012B in this embodiment are electrically connected to each other, and actually realize the function of a second winding 1012, and the first separate rectifier plate 1020A and the second separate rectifier plate 1020B are electrically connected to each other, and actually realize the function of a rectifier plate, but the separate setting changes the position layout of the second winding 1012 and the rectifier plate 1020. Of course, in other embodiments of the present case, the second winding 1012 may include three or more separate windings, and the rectifier plate 1020 may also include three or more separate rectifier plates, and the present case is not limited to this.

[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 Figure 10B and 10C As shown, no further details are given here.

[0203] Embodiment 11

[0204] See also Figure 11 , Figure 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 Figure 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 coils and is used to access the input alternating current. The magnetic core 1113 includes magnetic columns, and the coils constituting the first winding 1111 are arranged on the magnetic columns. The magnetic core 1113 mainly plays a role in guiding magnetic flux. The second winding 1112 is arranged outside the first winding 1111. On opposite sides of the second winding 1112, strip-shaped first pins 1130 and 1140 are respectively arranged. 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 Figure 11 The specific distribution manner of the first pin and the second pin of the transformer in

[0206] is the same as that of the comb-shaped pins in the above-mentioned embodiment, and will not be elaborated here. Figure 11 In addition, it can be seen that Figure 1I the difference between the second winding 1112 shown in Figure 11 and the second winding 112 shown in Figure 1I is that the outgoing pins of the second winding 1112 shown in

[0207] are not comb-shaped outgoing pins. The first pin 1130 and the second pin 1140 are respectively strip-shaped outgoing pin structures, but their effects are similar to those of the embodiment shown in

[0208] That is, by arranging the first pin 1130 and the second pin 1140 connecting the second winding 1112 to the rectifying board on the circuit board in a surface-mounting manner, the overall blocking of the AC path by the first pin 1130 and the second pin 1140 of the second winding 1112 is prevented. In this way, the gap existing 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, enabling the harmonics to have multiple paths to flow through, thereby reducing the proximity effect between the lines, reducing the current loss on the rectifying board, and improving the overall power supply efficiency.

[0209] Of course, it can be understood that the solution in this embodiment can also be analogized to the foregoing other embodiments, and will not be elaborated here.

[0210] In some embodiments of the present case, the first winding of the transformer is indirectly disposed on the magnetic core through a bobbin, that is, the first winding is disposed on the magnetic column through the bobbin, and the second winding is disposed outside the first winding. Similarly, the second winding can also be disposed outside the first winding through the bobbin, and the present case is not limited thereto.

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

[0212] In some embodiments of the present case, each switching element in the switching element group is connected by the first line and the second line according to a bridge rectifier circuit or a center-tapped rectifier circuit to form a rectifier circuit. Among them, both the bridge rectifier circuit and the center-tapped rectifier circuit are rectifier circuits well-known to those skilled in the art, and their specific circuit structures will not be described in detail herein. Those skilled in the art using other rectifier circuit structures well-known in the art to connect the circuit of the switching element group should also be within the protection scope of the present disclosure.

[0213] In some embodiments of the present case, 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. For example, in Figure 1B the illustrated embodiment, the second winding 112 can also be a flexible PCB winding, and in an embodiment such as Figure 1C shown, the second winding 112 can also be a rigid PCB winding.

[0214] In some embodiments of the present case, along the first direction X, at least one row of the switching elements (such as Figure 1D the first switching element 1221A shown) is directly electrically connected to the comb-shaped pin. That is, the switching element and the comb-shaped pin can be directly electrically connected without passing through other components such as capacitors and resistors.

[0215] In some embodiments of the present case, on the circuit board, multiple switching element groups can be electrically connected in series or in parallel. Among them, the relevant electrical connections between the respective switching element groups are also realized through the aforementioned first line and second line.

[0216] In some embodiments of the present case, an output terminal is also provided on the circuit board. The rectifying board is connected to the output terminal through a copper bus bar, so as to be electrically connected to an external device. Thus, 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 switching element group. Through the design of this output terminal, the transmission path of the output signal of the large current is shortened, and the energy loss of the output signal during transmission is effectively reduced.

[0217] In some embodiments of this case, the comb-shaped lead-out feet and the rectifying plate can be welded by vias or surface mounting.

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

[0219] In some embodiments of this case, the second winding can 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, etc. The PCB winding can be a flexible PCB winding or a rigid PCB winding.

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

[0221] For the rectifying module and the transformer provided by the embodiments of the present disclosure, by designing the lead-out feet connecting the second winding and the rectifying plate as comb-shaped lead-out feet, the comb-shaped lead-out feet include a plurality of comb teeth and combs adjacent to the comb teeth. The comb teeth are arranged along the first direction. At the same time, in cooperation with the circuit design of the switching element group on the rectifying plate, each switching element of the same switching element group is arranged along the second direction perpendicular to the comb teeth direction. There are gaps between the switching elements, and the gaps can provide a path for alternating current, that is, multiple second circuits can be formed in the second direction of the circuit board, so that harmonics have multiple paths to flow through, thereby reducing the influence of the proximity effect between the circuits, reducing the current loss on the rectifying plate, and improving the overall power supply efficiency.
