[0035] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.

[0037] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use, processing, transmission, provision, disclosure and application of relevant data comply with relevant laws, regulations and standards, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0038] With the rapid development of the data center and cloud computing industries, the demand for data center energy efficiency, reliability, and scalability is increasing. In some scenarios, data centers can adopt a heterogeneous acceleration resource pool deployment approach. Heterogeneous resource pool deployment involves integrating various types of computing resources into a resource pool through pooling technology. Through intelligent invocation and management of this resource pool, efficient, flexible, and scalable computing services are provided. This heterogeneous acceleration resource pool deployment approach results in higher power consumption requirements for electronic devices in the data center, which in turn leads to higher power requirements for these electronic devices.

[0039] The data center can be powered by an uninterruptible power supply (UPS) system with energy storage devices. Figure 1 , explain the UPS power supply system. Figure 1 One of the schematic diagrams of the power supply system provided in the embodiment of the present application is shown in FIG. Figure 1 The power supply system can include a voltage stabilizer, a power distribution unit (PDU), and electronic equipment. The electronic equipment is equipped with a power supply unit (PSU) and electrical components. The voltage stabilizer converts 380 volts (V) of AC power input into 220V AC through a process of converting AC to DC and DC to AC. This 220V AC power is then fed to the PSU via the PDU, which converts the 220V AC power into 12V DC power that can be used by the various electrical components in the electronic equipment.

[0040] During the research process, it was found that Figure 1 In the power supply system shown, multiple AC / DC conversion processes are required between the voltage regulator and the PSU within the electronic device. Furthermore, multiple stages of AC / DC conversion are also required within the PSU. Conversion losses occur at each stage, resulting in significant power loss. For example, if a data center uses AC power distribution, the power lost during the AC / DC conversion process accounts for approximately 5% to 10% of the data center's input power.

[0041] Therefore, an embodiment of the present application provides a power supply system, which can improve power conversion efficiency and reduce power supply loss by reducing the number of AC-DC conversions during the power supply process.

[0042] Figure 2 This is the second schematic diagram of the power supply system provided in the embodiment of this application. Figure 2The power supply system may include a voltage stabilizer 10, a power distribution unit 11, a DC transmission line 12, and an electronic device 13. The electronic device 13 is provided with a power supply module 130 and an electrical device 131.

[0043] The electronic device may be a server. From an architectural perspective, the server may be a whole cabinet server, a rack server, or a high-density server. From a functional perspective, the server may be a dedicated server or an artificial intelligence (AI) server, etc.

[0044] The electrical devices may include management electrical devices and load electrical devices, wherein the management electrical devices may include a manager module, and the load electrical devices may include at least one of the following: a processor, a memory, a heat sink, a retimer, and an adapter.

[0045] Exemplarily, the manager module may include but is not limited to a baseboard management controller (BMC) module.

[0046] Exemplarily, the processor may include, but is not limited to, at least one of the following: a central processing unit (CPU), a graphics processing unit (GPU), or a microcontroller unit (MCU).

[0047] For example, the heat sink may include, but is not limited to, a fan (FAN).

[0048] Illustratively, the adapter may include, but is not limited to, a high-speed access adapter. For example, the high-speed access adapter may be a high-speed serial computer expansion bus standard Peripheral Component Interconnect Express (PCIe) paddle card.

[0049] In some power supply scenarios, the DC power input from the power supply network can be converted into a first DC power through a transformer and input into the voltage regulator 10 in the power supply system. The voltage regulator 10 can input the first DC power to the power distribution unit 11, and the power distribution unit 11 can input the first DC power to the power supply module 130 through the DC transmission line 12.

[0050] For example, the DC power input from the power grid may be 10 kilovolt (kV) DC power, and the first DC power may be 380V DC power.

[0051] The voltage stabilizer 10 can stabilize the input 380V DC power to ensure that the voltage input to the power distribution unit is stable when there is voltage fluctuation in the input voltage.

[0052] The power distribution unit 11 can be used for power distribution processing and can be connected to at least one electronic device 13 . The power distribution unit 11 can distribute the 380V DC power input by the voltage regulator to the at least one electronic device 13 .

[0053] It should be understood that Figure 2 The number and form of the devices shown are for example only and do not constitute a limitation on the embodiments of the present application. In actual applications, the number of voltage stabilizers, power distribution units, DC transmission lines, electronic equipment, power supply modules, and electrical devices in the power supply system can be two or more. Figure 2 The power supply system shown is merely shown as an example including a voltage stabilizer, a power distribution unit, a DC transmission line, an electronic device, a power supply module and an electrical device.

[0054] like Figure 2 As shown, the power supply module 130 includes a DC power module 1300 and a power supply board 1301 , wherein the DC power module 1300 can be plugged into the power supply board 1301 , and the DC power module 1300 is also connected to the DC transmission line 12 .

[0055] Optionally, the DC transmission line may include, but is not limited to, a high voltage direct current (HVDC) DC power supply bus.

[0056] The DC power supply module 1300 may include a high-density parallel module. The DC power supply module 1300 may convert the first DC power input from the DC transmission line 12 into a second DC power through the high-density parallel module and input the second DC power to the power supply board 1301. It should be noted that the structure of the high-density parallel module will be Figure 5A is described in .

[0057] The power supply board 1301 may also be connected to the electrical device 131 , and the power supply board 1301 may supply power to the electrical device 131 according to the second direct current.

[0058] The voltage of the first direct current is greater than the voltage of the second direct current. For example, the first direct current may be 380V direct current, and the second direct current may be 12V direct current.

[0059] In the power supply system provided by the embodiment of the present application, the power supply process from the voltage stabilizer to the power supply module in the electronic device is all DC power supply, and there is no need for AC-DC conversion, thereby reducing the conversion loss in the AC-DC conversion process, which is beneficial to improving the power conversion efficiency of the power supply system; and, the power supply module further improves the power conversion efficiency and reduces the power loss of the power supply system by setting a high-density parallel module in the DC power supply module.

[0060] The power supply system provided by the embodiment of the present application can be used in high-power load scenarios. For example, in a data center scenario, the power supply system provided by the embodiment of the present application can be used for power supply. The voltage stabilizer in the power supply system can provide a first direct current to an electronic device (for example, a whole cabinet server) through a power distribution unit and a DC input wire (for example, an HVDC DC power supply busbar). In this process, no AC-DC conversion is required, thereby reducing the conversion loss in the AC-DC conversion process, and no AC-DC conversion module is required, which is conducive to simplifying the architecture of the power supply system; by setting a DC power supply module containing a high-density parallel module in the electronic device, it is conducive to improving the energy conversion efficiency of the electronic device and reducing power supply losses. In summary, the power supply system is conducive to reducing the power supply loss of the data center, improving the power conversion efficiency of the power supply system, simplifying the power supply and distribution architecture of the data center, and improving the overall energy efficiency of the data center, thereby solving the problem of large power supply loss of the power supply system in the high computing power scenario of the data center.

[0061] Next, combine Figure 3 , the above-mentioned power supply module 130 is further explained.

[0062] Figure 3 This is one of the structural diagrams of the power supply module provided in the embodiment of the present application, see Figure 3 ,exist Figure 2 Based on the structure of the power supply module 130 shown, the power supply module 130 may further include a first power adapter board 1302 .

[0063] like Figure 3 As shown, the first power adapter board 1302 can be connected to the power supply board 1301, and the first power adapter board 1302 is also used to connect to an AC power source.

[0064] Optionally, the first power adapter board 1302 can be plugged into the power supply board 1301 .

[0065] The first power adapter board 1302 is used to convert the alternating current (AC) power input from the AC power source into a second direct current (DC) power and input the second DC power to the power supply board 1301 .

[0066] In some embodiments, in the first power adapter board 1302, the input circuit of the AC power supply can adopt an N+N redundant design to ensure that in the event of a failure in any input circuit, the AC power supply can still supply power to the first power adapter board 1302 normally through the remaining input circuits except the failed input circuit.

[0067] The power supply module provided in the embodiment of the present application can integrate a highly modularized DC power supply module and a first power adapter board on a power supply board, making the structure of the power supply module simpler.

[0068] Next, combine Figure 4A and Figure 4B , further explain the first power adapter board.

[0069] Figure 4A This is one of the structural diagrams of the first power adapter board provided in the embodiment of the present application. Figure 4A The first power adapter board 1302 may include a first power connector 1302-0 and a power converter 1302-1.

[0070] The first power connector 1302 - 0 may be used to connect to an AC power source, and the first power connector 1302 - 0 may transmit AC power input from the AC power source to the power converter 1302 - 1 .

[0071] The power converter 1302 - 1 may be connected to the power supply board 1301 . The power converter 1302 - 1 may be configured to convert the alternating current (AC) input from the first power connector 1302 - 0 into a second direct current (DC) and input the second DC to the power supply board 1301 .

[0072] The number of the power converter 1302 - 1 and the first power connector 1302 - 0 may be at least one.

[0073] Figure 4B This is the second structural diagram of the first power adapter board provided in the embodiment of the present application. Figure 4B The first power adapter board 1302 may include two first power connectors 1302-0 and four power converters 1302-1.

[0074] like Figure 4B As shown, the first power connector 1302 - 0 and the power converter 1302 - 1 may be located on different sides of the first power adapter plate 1302 .

[0075] The first power connector can serve as a power input interface to supply power to the power supply board 1301 .

[0076] Optionally, the first power connector can be compatible with multiple power input specifications, so that the first power connector can be used in multiple power access scenarios. The power input specification can be used to indicate the design standards and requirements that the power input interface must meet.

[0077] In the power supply module provided in the embodiment of the present application, by setting a DC power supply module and a first power adapter board, the power supply module can be compatible with alternating current (AC) and direct current (DC) inputs, so that the power supply reliability of the power supply module is higher and the supported power supply scenarios are richer.

[0078] Next, combine Figure 5A to Figure 5E , the above-mentioned DC power supply module 1300 is further described.

[0079] Figure 5A This is one of the structural diagrams of the DC power supply module provided in the embodiment of this application. Figure 5A The DC power supply module 1300 may include a high-density parallel module 1300-0, and the high-density parallel module 1300-0 may include multiple power conversion units.

[0080] like Figure 5A As shown, the input ends of the multiple power conversion units are connected in parallel and connected to the DC transmission line 12 ; the output ends of the multiple power conversion units are connected in series and connected to the power supply board 1301 .

[0081] Exemplarily, the power conversion unit may be a high-density module daughter card.

[0082] In some data center scenarios, electronic equipment can be powered by air-cooled power supplies or high-performance power supplies. For example, the power density of air-cooled power supplies can reach 15 to 18 watts per cubic inch (W / in 3 ), the power density of high-performance power supplies can reach 35~40W / in 3 .

[0083] With the rapid development of artificial intelligence (AI) technology, the power requirements of electronic devices in data centers are increasing. For example, a 4U chassis in a heterogeneous acceleration resource pool equipped with 16 high-performance double-width accelerator cards will consume 9,000 watts (W) of power per unit, and a liquid-cooled chassis might consume up to 10 kilowatts (kW). In this scenario, if air-cooled or high-performance power supplies are still used, the electronic devices will require a large number of power supplies, which will occupy an excessive amount of space.

[0084] The high-density parallel module 1300-0 provided in the embodiment of the present application can achieve a high power density by connecting multiple power conversion units in parallel, thereby meeting the voltage conversion requirements of high-power electronic devices. Furthermore, after the multiple power conversion units within the high-density parallel module are connected in parallel, the integration level is high, and the high-density parallel module occupies a small space, which helps reduce the space occupied by the DC power supply module in the power supply module, thereby helping to reduce the space resources occupied by the power supply module in the electronic device.

[0085] In some embodiments, the power density of the DC power module can be determined based on the size (including length, width, and height) and output power of the DC power module. Power density = output power / (length × width × height).

[0086] For example, the size of the DC power module can be 185 mm × 147.9 mm × 39 mm, the output power can be 9000 W, and the output voltage can be 12 V. It can be calculated that the power density of the DC power module is 137.93 watts per cubic inch (W / in 3 ), the specific calculation process is as follows:

[0087] 9000W / (185mm×147.9mm×39mm)=9000W / (7.28in×5.82in×1.54in)=9000W / 65.25in 3 =137.93W / in 3 .

[0088] In a high-density parallel module, by connecting multiple power conversion units in parallel, it is also beneficial to improve the expandability and maintainability of the high-density parallel module.

[0089] For example, users can flexibly increase or decrease the number of power conversion units in the high-density parallel module based on changes in the power requirements of electronic devices. Alternatively, if some power conversion units in the high-density parallel module fail, the remaining power conversion units in the high-density parallel module can continue to operate to ensure the power supply stability of the electronic device.

[0090] Figure 5B This is the second structural diagram of the DC power supply module provided in the embodiment of this application. Figure 5B ,exist Figure 5A Based on the structure of the DC power supply module 1300 shown, the DC power supply module 1300 may further include a hot-swap module 1300 - 1 and a boost energy storage module 1300 - 2 .

[0091] like Figure 5BAs shown, the hot-swap module 1300-1 can be connected between the DC transmission line 12 and the input end of the high-density parallel module 1300-0, and the boost energy storage module 1300-2 can be connected between the hot-swap module 1300-1 and the input end of the high-density parallel module 1300-0.

[0092] The hot swap module 1300 - 1 can be used to perform hot swap processing on the DC power module 1300 .

[0093] Optionally, the hot-swap module 1300 - 1 can not only support the hot-swap processing operation of the DC power module 1300 , but also maintain good electromagnetic compatibility (EMC) during the hot-swap process, thereby ensuring that the DC power module 1300 is not subject to electromagnetic interference.

[0094] The boost energy storage module 1300 - 2 can be used to stabilize the first DC power input to the high-density parallel module 1300 - 0 and input the stabilized first DC power to the high-density parallel module 1300 - 0 .

[0095] In some scenarios, the input voltage of the DC power supply module 1300 may be undervoltage. In this case, the boost energy storage module 1300-2 can boost the input voltage to ensure the voltage stability of the first DC power input to the high-density parallel module.

[0096] The DC power supply module provided in the embodiment of the present application can ensure the power supply stability of the DC power supply module by arranging a hot-swap module and a boost energy storage module before the high-density parallel module.

[0097] Figure 5C This is the third structural diagram of the DC power supply module provided in the embodiment of this application. Figure 5C ,exist Figure 5B Based on the structure of the DC power supply module 1300 shown, the DC power supply module 1300 may further include a liquid cooling module 1300 - 3 .

[0098] The liquid cooling module 1300 - 3 is used to dissipate heat for the DC power module 1300 .

[0099] Figure 5D This is a schematic diagram of a DC power supply module provided in an embodiment of the present application. Figure 5D The liquid cooling module 1300 - 3 may be disposed inside the DC power supply module 1300 , and the liquid cooling module 1300 - 3 may include a liquid inlet pipe and a liquid outlet pipe.

[0100] Optionally, the liquid cooling module 1300-3 can be a high-performance, low-flow resistance liquid cooling plate, which may include a liquid inlet pipe and a liquid outlet pipe. The cold liquid can flow into the liquid cooling plate through the liquid inlet pipe, and flow out of the liquid cooling plate through the liquid outlet pipe after heat exchange treatment on the liquid cooling plate.

[0101] The DC power supply module provided in the embodiment of the present application improves the heat dissipation efficiency of the high-density parallel module by arranging a liquid cooling module in the high-density parallel module.

[0102] Figure 5E Schematic diagram of the location of a DC power module in an electronic device according to an embodiment of the present application. Referring to FIG5E , two DC power modules 1300 are disposed within the electronic device. The DC power modules 1300 are positioned adjacent to the processor (e.g., GPU) and signal processor (e.g., retimer) areas, respectively.

[0103] In electronic devices, processors and signal processors consume a lot of power. By arranging the DC power module 1300 close to the processor and signal processor areas in the electronic device, the power supply path of the DC power module can be shortened and power loss can be reduced.

[0104] Next, combine Figure 6A to Figure 6F , further explain the above-mentioned power supply board 1301.

[0105] Figure 6A This is one of the structural diagrams of the power supply board provided in the embodiment of this application. Figure 6A The power supply board 1301 may include a second power adapter board 1301-0 and a power supply connector 1301-1, wherein:

[0106] The second power adapter board 1301 - 0 is connected to the output end of the DC power module 1300 and the power supply connector 1301 - 1 respectively.

[0107] The second power adapter board 1301 - 0 may be used to input the second DC power provided by the DC power module 1300 into the power supply connector 1301 - 1 .

[0108] The second power adapter board 1301-0 may be provided with a second power connector, which may be connected to the power output interface of the DC power module 1300. The second power connector may be compatible with a variety of power input specifications, allowing the second power connector to be used in a variety of power access scenarios.

[0109] The current of the second DC power input by the DC power supply module 1300 to the power supply board 1301 is very large, so the DC power supply module needs to be equipped with multiple power output interfaces. In this case, multiple second power connectors can also be correspondingly set in the second power adapter board 1301-0 to realize the extended processing of the power input interface through the second power adapter board 1301-0.

[0110] In some embodiments, the structure of the power supply board 1301 can also be as follows: Figure 6B shown. Figure 6B This is the second structural diagram of the power supply board provided in the embodiment of this application. Figure 6B ,exist Figure 6A Based on the structure of the power supply board 1301 shown, the power supply board 1301 may further include a power input interface 1301 - 2 .

[0185] Power management devices can be used to manage the power supply of electronic devices.

[0186] Optionally, the power management device may be a management module in an electronic device, for example, a BMC module.

[0187] In some embodiments, the management electrical device can be used to adjust the power supply mode of the DC power module and the operation mode of the load electrical device according to the power consumption data of the load electrical device and the load demand of the load electrical device sent by the management controller.

[0194] In some embodiments, the management controller may also send a pre-trained AI model to the management electrical devices in the electronic device. The management controller may determine the power consumption data of the load electrical devices in a future period based on the historical power consumption data and / or real-time power consumption data of the load electrical devices through the pre-trained AI model, and adjust the power supply mode of the DC power supply module and the operating mode of the load electrical devices based on the power consumption data in the future period.

[0195] Pretraining is a model training strategy that focuses on using large-scale datasets to initially train the model, enabling it to learn general feature representations. This process is similar to the basic learning phase humans undergo before acquiring new knowledge, accumulating experience through extensive reading and observation. The core idea of ​​pretraining is to first train a basic model on general data, enabling it to acquire broad feature representation capabilities. Then, through transfer learning or fine-tuning, this model is adapted to a specific task, thereby improving task performance and reducing training costs.

[0196] A pre-trained AI model is one that is designed based on a large-scale dataset of load electrical devices, with corresponding training tasks designed and trained on a large-scale neural network algorithm structure to achieve learning and implementation. The resulting neural network model and its parameters have strong generalization capabilities. Subsequent tasks can be used to extract features or fine-tune tasks based on this model to achieve specific task objectives. By pre-training on large-scale datasets, AI models can learn rich feature representation capabilities. For example, they can learn the relationship between the power consumption data of load electrical devices and load requirements based on these data.

[0197] For example, the large-scale data set may include historical power consumption data and / or real-time power consumption data of the load electrical devices, and the large-scale data set may also include historical load demands and / or real-time load demands of the load electrical devices.

[0198] Training tasks can include self-supervised learning and generative learning. Self-supervised learning refers to designing pre-training tasks using the data's inherent structure without the need for manual labeling; generative learning refers to learning the data's distribution through a model and generating new data samples.

[0199] The neural network algorithm structure can be a convolutional neural network (CNN), a recurrent neural network (RNN), a long short-term memory network (LSTM), etc., or it can be a model built on an attention network, such as a generative pre-trained transformer (GPT), etc., which is not limited in this application.

[0200] An attention network refers to a network model that uses the attention mechanism for training. The model assigns different weights to each part of the input sequence, thereby extracting more important feature information from the input sequence, so that the model ultimately obtains more accurate output.

[0201] Fine-tuning involves further training a pre-trained AI model on a task-specific dataset to adjust model parameters and better adapt it to the target task. During fine-tuning, most layers of the pre-trained AI model are typically frozen, with only newly added layers trained or a small number of key layers adjusted. This preserves the learned features of the pre-trained AI model while enabling rapid adaptation to the specific requirements of the new task. Choosing the appropriate learning rate and number of training rounds is also crucial for successful fine-tuning.

When the load demand is low, the management electrical device may adopt the low power consumption mode, that is, the clock frequency or voltage of the processor in the load electrical device is reduced, and the frequency of the heat sink is reduced to reduce the power consumption of the processor and heat sink. When the load demand is high, the management electrical device may adopt the high power consumption mode, that is, the clock frequency or voltage of the processor is restored to ensure processor performance, and the frequency of the heat sink is restored to ensure heat dissipation performance.

[0218] Exemplarily, the power supply mode may include a high-power power supply mode and a low-power power supply mode. For example, when the load demand is large, the high-power power supply mode may be used, i.e., the output power of the DC power supply module is increased; when the load demand is small, the low-power power supply mode may be used, i.e., the output power of the DC power supply module is reduced.

[0219] Optionally, the management electrical device analyzes the operating mode of the load device to establish a relationship between the power consumption data of the load electrical device and the load rate (or performance), as well as the relationship between the power consumption data of the load power supply device and the power supply mode of the DC power supply module.
