[0048] High-power power supply devices are widely used in the industrial industry. Due to the variety of industrial application scenarios, the power supply requirements of different application scenarios are not the same. For example, in some application scenarios such as heating and metal wire drawing, the power supply devices in these application scenarios mostly need to input low voltage and high current, but the specific output requirements are different. Some require energy feedback, and some need to output the corresponding voltage according to different actual requirements.

[0049] Existing power supply devices cannot be compatible. Most power supply manufacturers only develop a power module or other form of power supply structure for one or a few types of power supply topology circuits for each application scenario. When different hardware topologies are involved, it is necessary to redevelop structural parts to be applied to power supply devices with different power supply topology circuits. This will mainly bring the following problems:

[0050] 1. Low development efficiency and long development cycle;

[0051] 2. When producing different power supply devices, it is necessary to redesign the structural parts or even re-open the mold, which is costly;

[0052] 3. There are many types of products and the maintenance cost is high.

[0053] In order to solve the problem that the existing power supply devices cannot achieve compatibility and cannot meet the power supply requirements of different application scenarios, the utility model proposes a power supply module and a power supply device.

[0054] Reference Figures 1 to 6 The power module includes multiple power function modules, a water cooling plate 200 and an isolation full-bridge module. At least one side of the water cooling plate 200 is provided with multiple installation positions corresponding to the multiple power function modules, and the multiple power function modules are detachably installed in the corresponding installation positions.

[0055] The modular design of multiple power function circuits of the power topology circuit 100 can facilitate production, processing, storage, installation, and transportation, and can also reduce processing and production and transportation costs. Different power functions are realized by different power function modules. Each power function module is provided with a connection terminal, and multiple power function modules are connected to form a preset power topology circuit through the connection terminal. Different topology circuits are formed by different power function modules to meet the use requirements of different application scenarios.

[0056] The isolation full-bridge module is fixedly arranged on the water-cooled plate, and a plurality of power function modules are connected to the isolation full-bridge module through corresponding connection ends. The isolation full-bridge module includes an isolation circuit module 180, a filter circuit module 162, and a full-bridge chopper circuit module 170 connected in sequence. The isolation full-bridge module is fixedly arranged on the water-cooled plate 200 to achieve pre-installation, so as to further reduce the assembly steps and assembly processes of the power module by reducing the assembly process of the isolation full-bridge module, thereby improving the production assembly efficiency.

[0057] Compared with some existing power supply devices and other power supply structures such as power supply modules with power supply topology circuits, which need to be cooled by forced air cooling by setting fans, at least one side of the water-cooling plate 200 shown in the present application is provided with multiple installation positions corresponding to multiple power supply function modules. By planning multiple installation positions on at least one side of the water-cooling plate 200 corresponding to multiple power supply function modules of multiple power supply topology circuits 100, the water-cooling plate 200 carries the power supply topology circuit 100, which can improve the utilization of space and play a role in heat dissipation. Using the water-cooling plate 200 instead of the fan can reduce the space occupied while achieving heat dissipation and cooling, and reduce the space requirements for the use environment.

[0058] Each power function module is provided with a connection end, and a plurality of power function modules are connected to form a required power topology circuit 100 through corresponding connection ends. A plurality of power function modules can be detachably installed in corresponding installation positions, which can facilitate wiring, assembly, and conversion of different topologies. Most of the power function modules can be shared when applied to different power supply devices, involving a small amount of modification and avoiding redesign of molds. After the pre-installation of the isolation full-bridge module is realized, the strategies and application methods of different power products can be applied by replacing some power function modules, effectively reducing product development time, speeding up the pace of project development, and reducing production and maintenance costs. In this way, the problem of inconvenient wiring can be avoided, and an integrated design can be realized, making the overall structure more compact, so as to further reduce the waste of space while achieving heat dissipation, and greatly improve the power density of the power supply. In addition, the power function module is modularly designed and installed in the corresponding installation position of the water-cooled plate 200 through a detachable connection, which can also facilitate subsequent disassembly, maintenance and replacement, effectively reducing maintenance costs and maintenance difficulties.

[0059] Each power supply function module may be provided with at least one connection terminal, and the connection terminal may be specifically divided into an input terminal, an output terminal, etc. according to the signal direction of the power supply topology circuit 100, and one or more connection interfaces, terminal blocks, connection wires, plug-in structures, etc., may be respectively provided at the corresponding input terminal, output terminal, etc. The specific settings may be based on actual conditions and will not be elaborated here.

[0060] In some embodiments of the present application, the water-cooled plate 200 is provided with multiple mounting positions corresponding to multiple power function modules, and multiple power function modules are detachably mounted in the mounting positions corresponding to the water-cooled plate 200. The number of mounting positions of the water-cooled plate 200 can be optionally set to be the same as or different from the number of power function modules. When the number of power function modules is the same as the number of mounting positions of the water-cooled plate 200, multiple power function modules can be optionally mounted one-to-one on multiple mounting positions corresponding to the water-cooled plate 200; when the number of mounting positions of the water-cooled plate 200 is different from the number of power function modules, multiple power function modules can be optionally mounted on part or all of the mounting positions of the water-cooled plate 200, and the same mounting position can be used to install the corresponding one or more power function modules.

[0061] As a further solution, the power topology circuit 100 can also be divided into multiple circuit parts such as an input power part and an output power part corresponding to multiple power function modules, and multiple installation positions are planned on the water cooling plate 200 corresponding to each circuit part, and multiple circuit parts and their corresponding circuit components are installed one-to-one at multiple installation positions; wherein each circuit part includes one or more power function circuit modules. Taking the division of the power topology circuit 100 into multiple circuit parts such as an input power part and an output power part as an example, the input power part at least includes an input filter circuit module, and the output power part at least includes an output rectifier module 150, an output filter circuit module 161, etc. Specifically, after determining the position where the isolation circuit module 180, the filter circuit module 162 and the full-bridge chopper circuit module 170 of the isolation full-bridge module and the related electrical connection components are connected and fixed on the water cooling plate 200 and dividing the power topology circuit 100 into multiple circuit parts according to actual conditions, at least one power function circuit module corresponding to each circuit part is set with an installation position on the water cooling plate 200.

[0062] It should be noted that the multiple installation positions provided on the water-cooled plate 200 shown in the present application can be provided on at least one surface of the water-cooled plate 200. Specifically, the water-cooled plate 200 has a relative upper surface and a lower surface, at least part of the multiple installation positions are provided on the upper surface of the water-cooled plate 200, and the other parts of the multiple installation positions are provided on the lower surface of the water-cooled plate 200. By planning the layout of the installation positions of the water-cooled plate 200, the space utilization rate is improved, and the power density of the power supply is further improved. The power module shown in the present application is applied to a power supply device. Specifically, according to the layout of the power supply device, the position of each power function module can be planned and then the position of each installation position on the water-cooled plate 200 can be planned accordingly; or, it can also be that at least one installation position is planned on the water-cooled plate 200 in advance, and then the specific installation position of each power function module is further planned from the at least one installation position: specifically, according to the size of the multiple power function modules, the connection relationship of the multiple power function modules, etc., the installation position for the corresponding power function module is determined in the multiple installation positions; or, the positions of the multiple power function modules to be installed are further planned in the determined at least one installation position. Specifically, multiple installation positions and layouts may be arranged according to actual conditions and are not limited here.

[0063] In addition, according to actual needs, connection holes, connectors with connection holes, connection rows, positioning grooves and other connection structures can be set on the water-cooled plate 200 shown, so as to provide positioning and installation of multiple power function modules. The above-mentioned connection structure can be set at any position of the water-cooled plate 200, and an adjustable adapter structure can be set accordingly, so that the installation position of the power function module can be adjusted to be suitable for installation of power function modules of different types, sizes, shapes or different fixing methods; or, the above-mentioned connection structure can also be set corresponding to the position of each installation position. The size, shape, fixing method, etc. of the power function modules shown in this application can be the same or different. Multiple power function modules can be detachably installed in corresponding installation positions, and multiple power function modules can be connected to corresponding installation positions by bonding, screwing, clamping, etc. In addition, in order to avoid displacement during transfer, transportation and use, after the installation of multiple power function modules is completed, multiple power function modules can be further connected and fixed to the corresponding installation positions on the water-cooled plate 200 by welding, bonding, etc. The power module shown in the present application can be applied to a power supply device, and the power module can be installed in the housing 300 of the power supply device. Specifically, a mounting hole and other connecting structures can be provided on the housing 300 of the power supply device to further realize the positioning and installation of the power function module.

[0064] In the embodiment of the present application, the power module is applied to the power supply device. The power module shown in the present application can be applied to one or more different power topology circuits 100. When used to be compatible with different power topology circuits 100, the power topology circuit 100 can be divided into multiple power function modules according to the circuit principle of the power topology circuit 100. At least one of the multiple power function modules can be connected into different power topology circuits 100 by adding or subtracting components, changing the circuit connection method, or as a whole by adding, deleting or replacing other power function modules of the same type. In this way, the use requirements of different application scenarios can be met. The power module is applied to different power supply devices, and most of the power function modules and circuit components are shareable. When there are multiple power function modules of the same type or the power function modules used to realize the same power function can be set to multiple different types, in order to reduce the amount of changes in the manufacture of power products, improve project development efficiency, and reduce costs, when applied to different power supply devices, the corresponding power function modules can be optionally added or replaced without changing other power function modules. The compatible design of the power module and the power supply device shown in the present application can be optionally implemented in any one of the following or more embodiments:

[0065] As an example, the required power function module can be adopted according to the power topology circuit used, and the corresponding power function module can be installed in the corresponding installation position of the water cooling plate 200. This solution has a simple connection relationship, is convenient for processing and production, and can effectively reduce processing costs. It is suitable for producing and processing compatible power modules. When applied to different power supply devices, the corresponding power function modules can be added, reduced or replaced without changing other power function modules. By processing into power modules with different power topology circuits 100, different models or types of power supply devices can be further processed, avoiding the need to redesign the mold and opening the mold, and can also comprehensively reduce the overall production cost.

[0066] As another example, a plurality of power function modules that can be used to implement the same power function can be set on the water cooling plate 200 at the same time, and the required power function modules can be turned on by setting a switch circuit according to the required power topology circuit 100. This solution can be applied to compatible power supply devices to implement different electrical functions through the same power supply device.

[0067] As another example, for multiple power function modules used to realize the same power function, multiple installation positions are respectively set on the water cooling plate 200, and corresponding power function modules are installed in corresponding installation positions according to the required power topology circuit 100. For power function circuits that are not needed, their corresponding installation positions are left blank or other power function modules are installed in their corresponding installation positions. This solution is suitable for producing and processing compatible power modules. The positions of each power function module can be flexibly set. By processing into power modules with different power topology circuits 100, different models or types of power supply devices can be further processed, avoiding the need to redesign the mold to reduce production costs, and facilitating processing and reducing processing errors.

[0068] The compatibility functions shown in this application can be implemented by adopting any one of the above methods, a combination of multiple methods, or other more methods according to actual conditions, and are not limited here.

[0069] In addition, it should be noted that, in addition to the power function module, the power topology circuit 100 also includes other loss-dissipating circuit components, circuit components that have strict requirements on the connection position or whose position will not change significantly when applied to different power supply devices, and other electrical components, electrical connection structures and other circuit components. Such circuit components can be optionally pre-installed at corresponding positions on the water cooling plate 200, or when planning the installation position of the power function module, the installation position of such circuit components is also planned on the water cooling plate 200; the specific settings can be based on actual conditions and are not limited here.

[0071] Specifically, the input filter circuit module includes a common mode filter circuit module 110 and a differential mode filter circuit module 120. The differential mode filter circuit module 120 can specifically adopt any one of a DC bus filter circuit module 121 and an electrolytic capacitor filter circuit module 122. When the input filter circuit module adopts the DC bus filter circuit module 121, the transient current required for the switch can be provided by the thin film bus capacitor; when the input filter circuit module adopts the electrolytic capacitor filter circuit module 122, low output ripple can be achieved and the output voltage accuracy can be improved. Specifically, the corresponding input filter circuit module can be selected according to the actual power supply device and the adopted power supply topology circuit 100.

The input rectifier module 140 is connected to the input filter circuit module through a corresponding connection terminal, and the second power supply input terminal is connected to the input rectifier module 140 for inputting a preset AC voltage.

[0076] By transforming the power function module of the input power part, it is suitable for inputting different DC voltages or AC voltages. Specifically, one or more DC voltages (or AC voltages) can be preset according to actual use requirements, and the power power range suitable for the power supply device to input can be further determined, and at least part of the power function module or the device of the power function module can be transformed to be suitable for inputting the preset DC voltage (or preset AC voltage). The water-cooled plate 200 can be applied to a DC input power supply device or an AC input power supply device according to actual needs. It should be noted that when only the first power input terminal is provided, it can be applied to a DC input power supply device or other input power supply devices; when only the second power input terminal is provided, it can be applied to an AC input power supply device; when the first power input terminal and the second power input terminal are provided at the same time, it can be applied to power supply teaching equipment, practical training test equipment or other compatible equipment, and the user can choose to connect DC power through the first power input terminal to use as a DC input power supply device, or connect AC power through the second power input terminal to use as an AC input power supply device by transforming the connected power function module.

[0077] Optionally, in the present application, the input rectifier module 140 shown can be specifically configured as an uncontrolled rectifier circuit module (three-phase uncontrolled rectifier circuit module). The above-mentioned first power input terminal and second power input terminal can be simultaneously provided on the water-cooled plate 200. The power module shown in the present application is applied to a power supply device, and the power supply device is provided with a power input interface, and the power input interface is used to input external direct current or external alternating current. When it is needed to be applied to a DC input power supply device, the power supply module is connected to the power input interface through the first power input terminal for accessing direct current; when it is applied to an AC input power supply device, the power supply module is connected to the power input interface through the second power input terminal for accessing alternating current. In addition, the water-cooled plate 200 shown is provided with a mounting position corresponding to the input rectifier module 140, and the first power input terminal and the second power input terminal can be respectively arranged on both sides of the corresponding mounting position or at other positions of the water-cooled plate 200. When applied to an AC input power supply device, the input terminal of the input rectifier module 140 is connected to the power input interface through the second power input terminal, and the output terminal of the input rectifier module 140 is directly connected to the input terminal of the common-mode filter circuit module 110 or connected to the common-mode filter circuit module 110 through the first power input terminal; when applied to a DC input power supply device, the mounting position corresponding to the input rectifier module 140 on the water-cooled plate 200 is left blank (that is, no other power function circuits are installed), and the first power input terminal can be connected to the power input interface through a wire, a wiring copper busbar, etc.

[0078] In one embodiment, when the input filter circuit module adopts the electrolytic capacitor filter circuit module 122, the multiple power supply function modules may further include a slow start circuit module 130, and the slow start circuit module 130 is connected between the input rectifier module 140 and the input filter circuit module through the corresponding connection terminal.

The power module is mounted in the shell 300 via the water-cooled plate 200 and the housing space 310 is divided into two spaces, one larger than the other, and part or all of the plurality of mounting positions are provided on the upper surface of the water-cooled plate 200.

[0102] Specifically, the housing space 310 of the shell 300 may be provided with an installation groove, an installation hole, a positioning stopper for installing the power module, or other connection structures such as a guide groove 320 may be provided in accordance with different installation methods to facilitate the installation of the power module shown. It should be noted that, here, according to the installation position of the power function module on the water-cooled plate, a connection structure for connecting the power module may be planned in the shell 300 or the housing space 310, so that the power module can separate the housing space 310 into two spaces with a larger upper portion and a smaller lower portion in the assembled state, and the position of the connection structure may be planned according to the structure of the power module, so as to avoid the problem of being unable to adapt and install the power module; or, according to the layout of the housing space 310, the position of the connection structure may be planned, and most of the power function modules of the power module may be designed to be installed on the upper surface of the water-cooled plate 200 through the corresponding installation positions, so that the power module can set the position of each power function module corresponding to the two spaces with a larger upper portion and a smaller lower portion in the housing space 310; the specific setting may be based on actual settings, and is not limited here.

[0103] Optionally, the housing 300 has multiple sides, and the housing space 310 is enclosed by the multiple sides of the housing 300. When installing the power module, one or multiple adjacent sides of the housing 300 are opened, so that the power module can be installed in the housing space 310 through the open opening. After the installation of the housing 300 is completed, the multiple open sides are covered or closed by corresponding covers. In addition, according to actual conditions, heat dissipation holes or heat dissipation grilles with heat dissipation holes can be set in the upper space of the housing space 310 to further optimize the heat dissipation capacity.

[0104] The water-cooled plate 200 of the present application is a double-sided layout structure. After determining the positions of the isolation circuit module 180, the filter circuit module 162, the full-bridge chopper circuit module 170 and the related electrical connection components of the isolation full-bridge module connected and fixed on the water-cooled plate 200, the positions of multiple installation positions on the water-cooled plate 200 are reasonably planned, and the power function modules installed on the upper and lower surfaces of the water-cooled plate 200 are planned to achieve an integrated design, so that the overall structure is more compact, which is used to further reduce the waste of space while achieving heat dissipation, and greatly improve the power density of the power supply.

Such a setting can ensure that the internal structure of the power supply device is more stable, and avoid the water cooling plate 200 being suspended in the upper space of the accommodating space 310, which leaves too much space at the bottom of the power supply device and affects the stability of the overall structure. Of course, according to actual conditions, it is not excluded to set the power module to divide the accommodating space 310 into two spaces, one smaller at the top and one larger at the bottom, or two spaces on the left and right; the specific setting can be based on actual conditions and is not limited here.

The user can choose to connect DC power through the first power input terminal to use it as a DC input power supply device, or to connect AC power through the second power input terminal to use it as an AC input power supply device by converting the connected power function module.

[0108] The power module is installed in the shell 300, and a power input interface is provided on the shell 300. In order to reduce the use of connecting cables or other electrical connection structures, the first power input terminal and the second power input terminal are arranged close to the power input interface. The power module is used to connect to the power input interface through the first power input terminal when a preset DC voltage is input; or, the power module is used to connect to the power input interface through the second power input terminal when a preset AC voltage is input.

Here, the power output interface provided on the power supply device and the power output terminal provided on the water-cooled plate 200 can be separately provided or combined according to actual conditions, which is not limited here.

[0110] The positions of the above-mentioned power input interface, power output interface, etc. can be set according to actual conditions, and the number can be set to one or more; the specific settings can be based on actual conditions and are not limited here.

[0111] In addition, according to actual conditions, a display, indicator light or other functional components may be provided at any position of the housing 300 , and the specific settings may be based on actual conditions and are not limited here.

[0112] The power supply device includes a power supply module as shown in the above example of the present application. Since the power supply device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, so they will not be described one by one here.
