Description

Technical Field

[0001] This utility model relates to the field of pulse power supply technology, and in particular to a pulse power supply. Background Technology

[0002] In recent years, pulse power supplies have been gradually developed. Pulse power supplies with IGBTs as the core are gradually replacing traditional thyristor-based pulse power supplies and are used in fields such as accelerators and magnet power supplies. They usually need to meet the requirements of compact structure and easy operation and maintenance. For special application scenarios such as magnet loads, the power supply also needs to meet the requirements of low external interference and fast response.

[0003] In the existing technology, there are no relevant patents or literature records regarding the overall setup of such pulse power supplies based on IGBTs. In terms of interference, the two output pins of traditional high-frequency switching power supplies are often set up separately. If this setup is applied to the output of a pulse power supply, there will be significant electromagnetic interference, making it difficult to meet the needs of various applications.

[0004] Therefore, a new type of pulse power supply is needed to meet the requirements of low cost, compact structure, easy operation and maintenance, low external interference and fast response speed. Utility Model Content

[0005] The purpose of this invention is to provide a pulse power supply that is low in cost, compact in structure, easy to operate and maintain, and has low external interference and fast response speed.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model discloses a pulse power supply. By placing the transformer and reactor in the bottom area of ​​the cabinet, it facilitates corresponding testing and operation by the staff. At the same time, by setting the bridge circuit module in the middle or top area of ​​the cabinet according to the actual situation, the overall layout flexibility of the pulse power supply is improved while ensuring functionality. In addition, the use of stacked copper busbars for the energy storage module can reduce the external electromagnetic interference of the pulse power supply. This utility model discloses a pulse power supply with a more compact structure by reasonably setting the positions of each module, which is easy to disassemble, install and transport, and is suitable for various places.

[0009] Preferably, the system also includes an output filter inductor, which is disposed near the perimeter of the bridge circuit module. This perimeter can be located anywhere on the bridge circuit module (top, bottom, left, right), allowing the output filter inductor to be connected to the bridge circuit module close to the module, reducing wiring, lowering costs, and further improving structural compactness.

It should be noted that when the pulse power supply output is bottom-out, selecting the busbar to output from the back or side of the cabinet is more cost-effective.

[0018] Preferably, the stacked copper busbar includes a stacked output positive copper busbar and an output negative copper busbar, with an insulating layer disposed between the output positive copper busbar and the output negative copper busbar; the stacked busbar includes a positive copper busbar and a negative copper busbar, with an insulating pad disposed between the positive copper busbar and the negative copper busbar, the positive copper busbar being stacked with the output positive copper busbar and electrically connected through a conductive element, and the negative copper busbar being stacked with the output negative copper busbar and electrically connected.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0040] Example 1

[0041] like Figures 1-3 As shown, this embodiment provides a pulse power supply, including a cabinet 1, a transformer 2, a reactor 3, a rectifier module 4, and a bridge circuit module 6, which are installed inside the cabinet 1 and electrically connected in sequence.

It should be noted that, based on the multiple energy storage modules 7, each energy storage module 7 is equipped with multiple energy storage capacitors, which can meet the requirements of rapid response of the pulse power supply.

[0042] In one or more embodiments, the rectifier module 4, bridge circuit module 6, energy dissipation module 5, and energy storage module 7 are all independently configurable box-type module structures, and the cabinet 1 is equipped with power inlet / outlet ports, control wiring ports, etc. Figure 2As shown, based on the arrangement of each module within the cabinet 1, the cabinet 1 can be divided into a bottom area 11, a middle area 12, and a top area 13. The bottom area 11, the middle area 12, and the top area 13 are divided according to the specific arrangement of each module that makes up the pulse power supply. Each area can be arranged with single-layer or multi-layer modules according to the actual situation.

[0043] In one or more embodiments, an output filter inductor 8 is also included, which is disposed in the surrounding area of ​​the bridge circuit module 6.

[0044] In an optional implementation, the output filter inductor 8 is a separate component and can be independently set up as a box-type module. It can be placed adjacent to the bridge circuit module 6 in any position, either up, down, left, or right, so that the output filter inductor 8 and the bridge circuit module 6 can be placed close to each other, which can facilitate convenient connection, reduce wiring, reduce costs, and further improve the structural compactness.

[0045] In one or more embodiments, the transformer 2, reactor 3, rectifier module 4, bridge circuit module 6, energy dissipation module 5, output filter inductor 8, and several energy storage modules 7 can be arranged in two columns within the cabinet 1. These two columns include a left column 14 and a right column 15.

This facilitates the independent fixing of each module and allows for easy adjustment, interchange, installation, maintenance, and disassembly of the modules according to actual conditions, further improving the overall layout flexibility of the pulsed power supply and making it adaptable to different application scenarios.

[0046] In an optional implementation, the transformer 2 can be located in the bottom area 11 near the front of the cabinet 1, and the reactor 3 can be located behind the transformer 2.

[0047] In an optional implementation, the bridge circuit module 6 can be a full-bridge circuit module or a combination of two or more half-bridge modules.

[0048] In an optional implementation, the positions of the relevant modules in the left column 14 and the right column 15 can be swapped or adjusted according to the actual situation. The number of columns of energy storage modules 7 can be set to at least two columns according to the actual situation, and the number of energy storage modules 7 in each column can be increased or decreased according to the actual situation.

[0049] In an optional embodiment, the bottom region 11, the middle region 12, and the top region 13 corresponding to the left column 14 and the right column 15 have the same volume size.

[0050] In an optional implementation, the rectifier module 4 and the single energy storage module 7 have the same volume size in their corresponding spatial structures, and the energy dissipation module 5 and the output filter inductor 8 have the same volume size in their corresponding spatial structures.

[0051] This embodiment of a pulse power supply places the transformer 2 and reactor 3 in the bottom area 11 of the cabinet 1, facilitating operation and testing by staff. Simultaneously, by placing the bridge circuit module 6 in the middle area 12 or top area 13 of the cabinet 1 according to actual conditions, the overall layout flexibility of the pulse power supply is improved while ensuring functionality. Furthermore, using a stacked copper busbar 10 for the energy storage module 7 reduces external electromagnetic interference. This embodiment of a pulse power supply, through the reasonable arrangement of module positions, makes the pulse power supply compact, easy to disassemble and install, and provides good performance, making it suitable for various locations.

[0056] Example 3

[0057] like Figures 6-7As shown, this embodiment of the pulse power supply provides another specific and preferred pulse power supply arrangement structure based on embodiment 1. The control module 9 and the rectifier module 4 are arranged side by side on the top of the transformer 2. The bridge circuit module 6 is arranged adjacent to the top of the rectifier module 4. Several energy storage modules 7 are distributed and arranged above the bridge circuit module 6. The energy dissipation module 5 is arranged on the top of the energy storage module 7.

[0058] Specifically, such as Figures 6-7 As shown, transformer 2 can be set in the right column 15, and control module 9 and rectifier module 4 are set side by side above transformer 2.

[0061] In an optional embodiment, the energy dissipation module 5 can be located at the top of the left column 14 or at the top of the right column 15.

[0062] In an optional implementation, the energy dissipation module 5 can also be located at the bottom of the energy storage module 7, depending on the actual situation.

[0063] Example 4

[0064] like Figure 3 As shown, in this embodiment of a pulse power supply, based on embodiment 1, embodiment 2 or embodiment 3, a test port 20 is further provided in front of or laterally adjacent to the transformer 2.

[0065] In this embodiment, a pulse power supply has a test port 20 that can be used for testing voltage, pulse, control signals, etc. Setting the test port 20 close to the transformer 2 makes it convenient to operate and use.

[0066] In optional implementations, such as Figure 3 As shown, test port 20 can be set at the front of transformer 2 near the front of cabinet 1.

[0067] In optional implementations, such as Figure 6 As shown, test port 20 can be set in the reserved space adjacent to transformer 2 laterally.

[0068] Example 5

[0069] like Figures 2-11 As shown, in this embodiment of a pulse power supply, based on embodiment 1, the energy storage module 7 is provided with a stacked copper busbar 10 for output. The output end of the stacked copper busbar 10 is bent, and the wide surface after bending is arranged parallel to the stacked busbar 30, which is fixed to the tail end of the housing of the energy storage module 7 by an insulating component 104. Several stacked copper busbars 10 are combined and output through the stacked busbar 30. The stacked busbar 30 is connected to the busbar 40 through the bridge circuit module 6 and the output filter inductor 8. The busbar 40 extends out of the top or back of the cabinet 1.

[0070] In one or more embodiments, the stacked copper busbar 10 includes a stacked output positive copper busbar 101 and an output negative copper busbar 102, with an insulating layer 103 disposed between the output positive copper busbar 101 and the output negative copper busbar 102; the stacked busbar 30 includes a positive copper busbar 301 and a negative copper busbar 302, with an insulating pad 303 disposed between the positive copper busbar 301 and the negative copper busbar 302, and the positive copper busbar 301 is stacked with the output positive copper busbar 101 and electrically connected through a conductive element 50 (e.g., ...). Figure 10 , Figure 11 As shown in the figure, the negative copper busbar 302 is electrically connected to the output negative copper busbar 102 in a stack.

[0071] In an optional embodiment, each energy storage module 7 may be provided with an output positive copper busbar 101 and an output negative copper busbar 102, the output positive copper busbar 101 and the output negative copper busbar 102 are stacked, and an insulating layer 103 is provided between the output positive copper busbar 101 and the output negative copper busbar 102 to form an energy storage module 7 output by the stacked copper busbar 10, and multiple energy storage modules 7 are stacked and electrically connected to the stacked busbar 30.

[0072] In an optional embodiment, the negative copper busbar 302 and the insulating pad 303 may be provided with through holes. The conductive component 50, which is electrically connected to the wide surface of the bent output positive copper busbar 101, passes through the through hole and is electrically connected to the positive copper busbar 301. The conductive component 50 may include conventional conductive structures such as conductive studs, conductive wires, and conductive sheets.

[0073] This embodiment of a pulse power supply makes full use of the internal and external space of the cabinet 1. By combining the stacked copper busbar 10 and the stacked busbar 30, the copper busbar stacked busbar output structure of the pulse power supply is realized, which further reduces the external electromagnetic interference of the pulse power supply and reduces the overall size of the structure. The output can be selected from the top or back of the cabinet 1 according to the actual situation, making full use of the internal space of the cabinet 1 and further improving the compactness of the overall structure of the pulse power supply. By bending the output end of the stacked copper busbar 10, the wide surface of the bent part fits with the wide surface of the stacked busbar 30, which facilitates the installation of the stacked busbar 30 and the output pole of the energy storage module 7, and makes it easy to install and remove.

[0074] Example 6

[0075] like Figures 2-3 As shown, in this embodiment of a pulse power supply, based on any of embodiments 1-5, the cabinet 1 includes two stacked cabinet units 16, which are detachably connected. Each cabinet unit 16 includes a frame component and a cover plate component, and adjacent cabinet units 16 are connected vertically. It should be noted that if a single cabinet 1 is used, it may result in excessive height and weight. Therefore, using two cabinet units 16 is more convenient for transportation and installation compared to a single unit.

[0076] In this embodiment, a pulse power supply is provided, in which two stacked cabinet units 16 are connected to form a cabinet 1, which facilitates transportation and loading / unloading. After assembly, the cabinet 1 can save floor space. The stacked cabinet units 16 are provided with a sufficient number of detachable lifting ring mounting holes, which can be removed after on-site installation. After the stacked cabinet units 16 are assembled, the connection parts need to be tightened.

[0077] In optional implementations, such as Figure 3 As shown, the lower cabinet unit 16 can accommodate the installation of transformer 2, rectifier module 4 and an integer number of energy storage modules 7, while the upper cabinet unit 16 can accommodate an integer number of energy storage modules 7, bridge circuit module 6, energy leakage module 5 and output filter inductor 8.

[0078] In optional implementations, such as Figure 3 As shown, the lower cabinet unit 16 can accommodate a transformer 2, a rectifier module 4, a control module 9, a bridge circuit module 6, and an output filter inductor 8, while the upper cabinet unit 16 can accommodate an integer number of energy storage modules 7 and energy dissipation modules 5.

[0079] In one or more embodiments, the frame component may include a combination of the cabinet 1 frame and the module mounting bracket for installing and fixing each module. The cabinet 1 frame is a frame column structure designed to bear the load of the cabinet 1. The module mounting bracket is a perforated bracket for installing and fixing each module, so that each module is provided with an independent installation and fixing position within the cabinet 1 through the module mounting bracket. The frame component and the cover plate component are combined to form an installation space. The cover plate component may include a cover plate with a snap-lock structure for easy disassembly and grounding considerations to ensure electrical safety.

[0080] It is understandable that the volume of each cabinet unit 16 can be adjusted according to the actual situation such as manufacturing cost, hoisting cost, and production conditions. When the load on the cabinet 1 is large, special consideration needs to be given to the frame and columns of the cabinet 1 to determine the material and connection structure in order to ensure the overall strength of the cabinet 1, so as to realize the independent and stable fixation and interconnection of each module in the cabinet 1, improve the compactness of the pulse power supply, and facilitate the assembly and disassembly of the structure. In order to improve the overall strength of the cabinet 1, the base support can also be strengthened by component molding at the bottom of the lowest cabinet unit 16.

[0081] In one or more embodiments, vertical frame columns 17 can be respectively provided in the middle of the front and back of the cabinet 1, with the vertical frame columns 17 corresponding to the space between the left column 14 and the right column 15. This is to strengthen the structure of the cabinet 1 through the vertical frame columns 17 and to avoid the installation of the vertical frame columns 17 affecting the installation of each module.

[0082] In one or more embodiments, cabinet 1 may also be equipped with several components including a power indicator light, an alarm, a reset button, and an emergency stop button. Different functional components can be selected and configured according to actual needs to indicate the operating status of the pulse power supply.

[0083] In an optional implementation, each component can be mounted on the vertical frame column 17, and the position and size of each component are set according to ergonomics to facilitate operation and observation.

[0084] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
