Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of power electronics, and in particular, to a separated comb-type foot-out rectifier module and transformer. BACKGROUND

[0002] With the increasing demand for intelligent life, the demand for data processing is growing. The global energy consumption in data processing reaches hundreds of billions or even thousands of billions of degrees per year on average; and a large data center can cover tens of thousands of square meters. Therefore, high efficiency and high power density are key indicators for the healthy development of this industry.

[0003] With the increasing integration of electrical equipment per unit volume, the power supply for these electrical equipment is expected to have higher efficiency and higher power density. In order to meet the above requirements, it is necessary to develop low-voltage and high-current power supply. With the development of low-voltage and high-current power supply, the processing of high-current winding becomes more and more important, and the form of winding not only needs to match the placement of secondary rectifier tubes, but also needs to be highly manufacturable.

[0004] At the same time, in the high-current environment, there is a proximity effect problem between adjacent transmission lines. The so-called proximity effect problem in double-line transmission lines refers to the phenomenon that the alternating current in two conductors approaches each other. The proximity effect problem will increase the resistance of adjacent transmission lines, 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 plate is also particularly important. Poor design will cause excessive loss of the rectifier plate, low efficiency, and excessive heat, which poses a safety hazard.

[0005] In addition, in some cases, the windings of the transformer are not conducive to heat dissipation due to the overlapping parts between them. SUMMARY

[0065] like Figure 1A As shown, the rectifier module 100 includes a transformer 110 and a rectifier board 120. 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 multiple switching element groups (…). Figure 1A A circuit board (not shown in the figure). The rectifier board 120 and the transformer 110 are electrically connected to rectify the AC power from the transformer 110 into DC power. It should be noted that, for simplicity, the switching elements on the rectifier board 120 are not shown in the figure; the rectifier board 120 is only used for illustration. In other embodiments of this invention, a substrate (not shown in the figure) may also be provided between the transformer 110 and the rectifier board 120. The substrate has through holes for the comb-shaped leads of the second winding 112 to pass through, for fixing the second winding 112.

[0066] like Figure 1A and 1BAs shown, the transformer 110 comprises a magnetic core 113, a first winding 111 and a second winding 112. The first winding 111 is composed of coils for accessing input alternating current. The magnetic core 113 comprises a magnetic column 118, and the coils of the first winding 111 are arranged on the magnetic column 118. The magnetic core 113 mainly plays a role of magnetic conduction. The second winding 112 is arranged outside the first winding 111 and is used for electrically connecting the rectifier plate 120 to input alternating current output by the transformer 110 into the rectifier plate 120 for rectification. The second winding 112 comprises a first sub-winding and a second sub-winding. As shown, Figure 1C As shown, the first sub-winding comprises a plurality of first sub-winding wires 1122, and the second sub-winding comprises a plurality of second sub-winding wires 1123. The first sub-winding wires 1122 and the second sub-winding wires 1123 are arranged at intervals to form comb-shaped pins 1121 on opposite sides of the second winding 112, respectively. The comb-shaped pins 1121 are arranged along a first direction X. The comb-shaped pins 1121 comprise at least two comb teeth 1121A, and a comb gap 1121B is arranged adjacent to the comb teeth 1121A. Adjacent two comb teeth 1121A correspond to the comb teeth of the first sub-winding wires 1122 and the second sub-winding wires 1123, respectively. The comb-shaped pins 1121 are arranged alternately by the plurality of comb teeth 1121A and the comb gaps 1121B, and present a comb structure. The transformer 110 is electrically connected to the rectifier plate 120 through the comb teeth 1121A. In some embodiments, the transformer 110 and the rectifier plate 120 form a middle-extraction rectification, in which the first sub-winding and the second sub-winding flow through current in different half cycles of power frequency, respectively. In other embodiments, the transformer 110 and the rectifier plate 120 can also form a full-bridge rectification, in which the first sub-winding and the second sub-winding flow through current at the same time, which is related to the specific connection mode of the rectifier plate 120, and the present application does not limit this. It should be noted that the shape of the comb-shaped pins 1121 shown in the figure is only an example, and in other embodiments, the shape of the comb-shaped pins 1121 is not limited as long as it can be electrically connected and should be considered to belong to the protection scope of the present application. In some embodiments of the present application, the magnetic column 118 is a cylindrical body, and the axial direction of the magnetic column 118 is the first direction X. Here, the opposite sides of the second winding 112 refer to the two ends of the second winding 112, and the specific positions are related to the shape and structure of the second winding 112. Therefore, it can be understood that, Figure 1C and Figure 1C-1 As shown, the structure diagram of the sub-winding wires arranged at intervals is only a schematic, and in different embodiments, the first sub-winding wires 1122 and the second sub-winding wires 1123 are not necessarily straight lines.

[0067] As shown, Figure 1BAs shown, the second winding 112 comprises first sub-winding wires 1122 and second sub-winding wires 1123 arranged in intervals, and the first sub-winding wires 1122 and the second sub-winding wires 1123 form a U-shaped winding surface. The U-shaped winding surface is arranged outside the first winding 111. As described above, the comb-shaped pins 1121 are arranged at both ends of the U-shaped winding surface. The comb teeth at both ends of the U-shaped winding surface are arranged correspondingly. The comb-shaped pins 1121 at both ends of the U-shaped winding surface are electrically connected to the circuit board.

[0068] In the example embodiment, the first sub-winding wire can be a metal sheet or a PCB winding. Specifically, the metal sheet includes iron sheet, copper sheet, aluminum sheet, nickel sheet, tungsten sheet, molybdenum sheet, cobalt sheet, and various metal alloy sheets, including stainless steel sheet, nickel-based alloy sheet, copper alloy sheet, and aluminum alloy sheet. The PCB winding can be a flexible PCB winding or a rigid PCB winding. For example, in the example embodiment shown in Figure 1B In the example embodiment shown, the first sub-winding wire 1122 and the second sub-winding wire 1123 can be a metal sheet, and can also be a flexible PCB winding, which can be bent into a U-shaped winding.

[0069] In the example embodiment, as shown in Figure 1B The comb-shaped pins 1121 and the rectifier plate 120 can be welded through a via. In other embodiments of the present application, as shown in Figure 1D The comb-shaped pins 1121 and the rectifier plate 120 can also be welded through surface mounting. In addition, Figure 1D The example embodiment shown and Figure 1B The example embodiment shown are basically the same, and will not be described again. In addition, the present application does not limit the shape of the transformer magnetic core. For example, in Figure 1A and Figure 1B The transformer magnetic core is U-shaped, and in Figure 1D The transformer magnetic core is EE-shaped, and it should be understood that it can also be other shapes.

[0070] 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 set with the circuit board as the reference. When the position of the circuit board changes, the first direction X, the second direction Y, and the third direction Z can be different according to different embodiments.

[0071] In the example embodiment, as shown in Figure 1C-1As shown, in order to facilitate manufacturing, the transformer further comprises a winding placement plate 114. The first sub-winding and the second sub-winding are arranged on the same side of the winding placement plate 114. By arranging the first sub-winding and the second sub-winding on the same side of the winding placement plate 114, the first sub-winding and the second sub-winding can have the same heat dissipation performance, so that the second winding 112 can be better heat-dissipated. In some embodiments, the first sub-winding and the second sub-winding can be arranged on the outer side of the winding placement plate 114, i.e., the side away from the first winding 111, so as to be spaced apart from the first winding 111 by the winding placement plate 114, and at the same time, the first sub-winding and the second sub-winding are exposed on the outer side, so that the heat dissipation effect is better. Of course, in other embodiments, the first sub-winding and the second sub-winding can also be arranged on the inner side of the winding placement plate 114.

[0072] It should be understood that the winding placement plate 114 can be a flexible PCB plate or a rigid PCB plate, for example. In an exemplary embodiment, a plurality of heat dissipation holes (not shown in the figure) are further arranged on the winding placement plate 114, so as to provide better heat dissipation conditions for the second winding 112.

[0073] The rectifier module and the transformer provided by the embodiments of the present disclosure have the following advantages. The pins connected to the second winding and the rectifier plate are designed as comb-shaped pins. The comb-shaped pins comprise a plurality of comb teeth and a comb gap arranged adjacent to the comb teeth. The comb teeth are arranged in a first direction. At the same time, the structure of the rectifier plate shown in FIGS. 1 and 2 is adopted, so that the first line P in the first direction X and the second line Q in the second direction Y are formed on the rectifier plate. By leaving a gap between the switching elements of the adjacent switching element groups, a passage is provided for alternating current, so as to reduce the influence of the proximity effect between the lines, reduce the current loss on the rectifier plate, and improve the overall power supply efficiency. At the same time, by arranging the second winding in the form of the first and second sub-windings, the second winding is arranged in a spaced-apart manner without overlapping, so that the second winding can maintain good heat dissipation. Figures 8A to 8C and Figures 9A-9C The rectifier module and the transformer provided by the embodiments of the present disclosure have the following advantages. The pins connected to the second winding and the rectifier plate are designed as comb-shaped pins. The comb-shaped pins comprise a plurality of comb teeth and a comb gap arranged adjacent to the comb teeth. The comb teeth are arranged in a first direction. At the same time, the structure of the rectifier plate shown in FIGS. 1 and 2 is adopted, so that the first line P in the first direction X and the second line Q in the second direction Y are formed on the rectifier plate. By leaving a gap between the switching elements of the adjacent switching element groups, a passage is provided for alternating current, so as to reduce the influence of the proximity effect between the lines, reduce the current loss on the rectifier plate, and improve the overall power supply efficiency. At the same time, by arranging the second winding in the form of the first and second sub-windings, the second winding is arranged in a spaced-apart manner without overlapping, so that the second winding can maintain good heat dissipation.

The rectifier module of the present case can adopt the rectifier board shown in Figures 8A to Figure 8C and Figures 9A to Figure 9C .

[0117] In the exemplary embodiments, as shown in Figure 8A and 8A-1As shown, the rectifier plate includes a circuit board 821 and a plurality of switch element groups 822. The circuit board 821 includes a first face 821A and a second face 821B oppositely arranged. The plurality of switch element groups 822 are arranged on the circuit board 821.

It should be noted that the so-called "a and b are arranged along the first direction" and "a and b are arranged along the second direction" do not mean that a and b must be arranged along a straight line. Due to the need for process or actual manufacturing, when a and b are arranged along a certain direction, they can have a certain deviation or misalignment in the same direction, which is not limited in the present case.

[0121] The same switch element group 822 includes a first switch element 8221A and a second switch element 8221B.

Along the second direction Y, the comb-shaped output terminals 8121 on both sides of the second winding are located outside the first switch element 8221A and the second switch element 8221B, respectively, and are electrically connected through the corresponding comb teeth 8121A and the rectifier plate. On the circuit board 821, a first line P is arranged along the first direction X, and a second line Q is arranged along the second direction Y. The first line P and the second line Q are electrically connected to part of the first switch element 8221A and the second switch element 8221B, respectively, to connect the switch elements to form a rectifier circuit, wherein the potential at the connection between the first line P or the second line Q and the switch element is the same.

[0122] It should be noted that in some embodiments of the present case, Figure 8B and 8B-1 In the above, the switch element group 822 can not be centrally arranged along the second direction Y of the circuit board 821, so as to reserve a position for the capacitor (not shown in Figure 8B , see Figure 2C ) arranged on the circuit board 821.

[0123] In an exemplary embodiment, as Figure 8C In the above, the rectifier plate includes a circuit board 821 and a plurality of switch element groups 822. The plurality of switch element groups 822 are arranged on the same surface of the circuit board 821. The plurality of switch element groups 822 are arranged along the first direction X and used for rectifying the output current of the second winding 812.

[0124] The same switching element group 822 includes a first switching element 8221A and a second switching element 8221B. The first switching element 8221A and the second switching element 8221B are located on the same surface of the circuit board 821. The first switching element 8221A and the second switching element 8221B do not overlap along the second direction Y, but are arranged along the first direction X, i.e., they are staggered. Along the first direction, the first switching element 8221A and the second switching element 8221B can be completely staggered or partially overlapped, as long as the corresponding comb teeth 8121A can be staggered, all of which should be considered within the protection scope of this disclosure. Along the second direction Y, the comb-shaped leads 8121 on both sides of the second winding are located outside the first switching element 8221A and the second switching element 8221B, respectively, and are electrically connected to the rectifier board through the corresponding comb teeth 8121A. On the circuit board 821, a first line P is provided along the first direction X, and a second line Q is provided along the second direction Y. The first line P and the second line Q are electrically connected to portions of the first switching element 8221A and the second switching element 8221B, respectively, connecting the various switching elements to form a rectifier circuit. The potentials at the connection points between the first line P or the second line Q and the switching elements are the same. The first direction X and the second direction Y are perpendicular to each other. The term "corresponding arrangement" refers to a one-to-one correspondence between multiple comb teeth of the same or different windings in space. It should be noted that the figure only schematically shows one first line P and two second lines Q. In reality, it can be understood that the first line P and the second line Q can be set between different switching transistors or at positions adjacent to switching transistors. The first line P can serve as a power path, and the second line Q can serve as a harmonic path. Because of the existence of the second line Q, harmonics can have multiple paths to flow, thereby reducing the proximity effect between lines, reducing current loss on the rectifier board, and improving the overall power supply efficiency.
