Description

TECHNICAL FIELD

[0001] The present application relates to the field of power supply, in particular to a power module and a power supply method. BACKGROUND

[0002] With the development of computing technology, the scale of data centers is getting larger and larger, and enterprises have higher and higher requirements for the density, cost and energy efficiency of power supply systems. Many application fields need to realize corresponding functions through data storage, data exchange or data calculation operations of large-scale computing devices. The place where the large-scale computing devices are placed and managed is usually called a data center or computer room. The power supply of the computing device bears the function of supplying power to the computing device load and ensuring the normal operation of the load. The existing power supply of the computing device usually adopts a redundant power supply design to improve the reliability of the computing device and ensure the normal power supply of the computing device.

[0003] Generally speaking, the configuration of each data center is specific. Due to specific systems and components, the computing devices that can be accommodated by the data center are fixed, and it is very time-consuming and expensive to change the configuration of the data center. SUMMARY

[0004] The embodiments of the present application provide a power module and a power supply method, which can support 2n branch power supply inputs of (n+1) power modules of the power module. When receiving 2n branch power supply inputs, (n+1) power modules in the power module can still realize power supply. In the case that the existing configuration of the data center does not support, for example, the number of interfaces of the power supply and the power distribution column head cabinet is insufficient, and the case that the computer room needs to be transformed, the computing device loaded with the power module supporting 2n branch power supply inputs can be used to save the interfaces of the power supply and the power distribution column head cabinet, and avoid the transformation of the computer room.

[0005] In a first aspect, the embodiments of the present application provide a power module, comprising (n+1) power modules and 2n input connectors: the input connectors are used to connect power supply and power modules; (n+1) power modules include (n-1) double-input power modules and 2 single-input power modules, each double-input power module includes a first input port and a second input port, the first input port and the second input port are connected to an input connector respectively, and each single-input power module is connected to an input connector; wherein n is an integer greater than 1; when 2n input connectors are connected to the power supply input of the power supply, (n+1) power modules in the power module realize power supply.

[0006] The power module provided by the embodiment of the present application is in the form of n+1 power supply configuration, and the power module can support 2n branch power supply input. In this way, in the case that the existing data center configuration does not support, for example, the case that the interface quantity of the power supply and the power distribution column head cabinet is insufficient, and the case that the computer room needs to be reformed, the 2n branch power supply input can be used to save the interface of the power supply and the power distribution column head cabinet, so that the computer room reform is avoided and the normal power supply is not affected.

[0007] In combination with the first aspect, in a possible implementation, each double-input power module receives two-way power supply input of the power supply, the first single-input power module of the two single-input power modules receives one-way power supply input of the two-way power supply input, and the second single-input power module of the two single-input power modules receives the other way power supply input of the two-way power supply input.

[0008] In a possible implementation, when one-way power supply input fails, n power modules in the power module group realize power supply, and the n power modules include power modules other than the first single-input power module in the (n+1) power modules; when the other way power supply input fails, n power modules in the power module group realize power supply, and the n power modules include power modules other than the second single-input power module in the (n+1) power modules.

[0009] In this connection mode, when both two-way power supply inputs are normal power supply, (n+1) power modules in the power module group realize power supply. The two single-input power modules receive two independent power supply inputs, and in the case that any one of the two-way power supply inputs fails, one single-input power module serves as a redundant power supply of the other single-input power module to realize reliable power supply.

[0010] In combination with the first aspect, in a possible implementation, the two single-input power modules include a first single-input power module and a second single-input power module, (n-1) double-input power modules are sequentially connected to the 1st input connector to the (2n-2)th input connector based on the positions of the 2n input connectors; the first single-input power module is connected to the (2n-1)th input connector; and the second single-input power module is connected to the 2nth input connector. In this way, the input connectors are sequentially connected according to the industry common interface habit, and therefore the last two input connectors serve as the input connectors for connecting the two single-input power modules. In the case that the power supply path connected to the last input connector fails, n power modules in the power module group realize power supply, and in the case that both two power supply paths connected to the last two input connectors fail, only (n-1) power modules in the power module group realize power supply. Here, the most possible connection mode is provided, which fully adapts to the interface habit of users and has practical application universality.

[0011] In a possible implementation, all odd-numbered input connectors are connected to one power supply input of the power supply, and all even-numbered input connectors are connected to another power supply input of the power supply; if the one power supply input connected by all odd-numbered input connectors fails, the other power supply input supplies power to n power supply modules connected by all odd-numbered input connectors, the n power supply modules including power supply modules other than the first power supply module in the (n+1) power supply modules; or, if the one power supply input connected by all even-numbered input connectors fails, the other power supply input supplies power to n power supply modules connected by all even-numbered input connectors, the n power supply modules including power supply modules other than the second power supply module in the (n+1) power supply modules; or, if one power supply module in the (n+1) power supply modules fails, the remaining n power supply modules supply power.

[0012] In a second aspect, an embodiment of the present application provides a power supply method, which includes: receiving, by a power supply module, two-way power supply input provided by a power supply; supplying, by the power supply module, power to a load based on the two-way power supply input; the power supply module includes (n+1) power supply modules and 2n input connectors: the input connectors are used to connect the power supply and the power supply modules; the (n+1) power supply modules include (n-1) double-input power supply modules and 2 single-input power supply modules, each double-input power supply module includes a first input port and a second input port, the first input port and the second input port are connected to one input connector respectively, and each single-input power supply module is connected to one input connector; wherein n is an integer greater than 1; when the 2n input connectors are connected to the power supply input of the power supply, the (n+1) power supply modules in the power supply module realize power supply.

[0013] The power supply method provided by the embodiment of the present application is applied to a power supply module with a configuration form of n+1, and the power supply module can support 2n branch power supply inputs. In this way, in the case that the existing data center configuration does not support, for example, the interface quantity of the power supply and the power distribution column header cabinet is insufficient, and the case that the machine room needs to be reformed, 2n branch power supply inputs can be used to save the interfaces of the power supply and the power distribution column header cabinet, so that the machine room is not reformed and the normal power supply is not affected.

[0014] In combination with the second aspect, in a possible implementation, each double-input power supply module receives two-way power supply input of the power supply, a first single-input power supply module in the 2 single-input power supply modules receives one-way power supply input in the two-way power supply input, and a second single-input power supply module in the 2 single-input power supply modules receives another-way power supply input in the two-way power supply input.

[0015] In a possible implementation, when one power supply input fails, n power modules in the power module group supply power, the n power modules including (n+1) power modules except the first single-input power module; when another power supply input fails, n power modules in the power module group supply power, the n power modules including (n+1) power modules except the second single-input power module.

[0016] In this connection mode, when both power supply inputs are normal, (n+1) power modules in the power module group supply power. Two single-input power modules receive two independent power supply inputs, and in the case of failure of any one of the two power supply inputs, one single-input power module serves as a redundant power supply for the other single-input power module to realize reliable power supply.

[0017] In combination with the second aspect, in a possible implementation, the two single-input power modules include a first single-input power module and a second single-input power module, based on the positions of the 2n input connectors, (n-1) double-input power modules are sequentially connected to the 1st input connector to the (2n-2)th input connector; the first single-input power module is connected to the (2n-1)th input connector; and the second single-input power module is connected to the 2nth input connector. In accordance with the industry common interface habit, the input connectors are sequentially connected, and therefore the last two input connectors serve as input connectors for connecting the two single-input power modules. In the case of failure of the power supply path connected to the last input connector, n power modules in the power module group supply power, and in the case of failure of both power supply paths connected to the last two input connectors, only (n-1) power modules in the power module group supply power. Here, the most possible connection mode is provided, which fully adapts to the interface habit of users and has practical universality.

[0018] In a possible implementation, all odd-numbered input connectors are connected to one power supply input of a power supply, and all even-numbered input connectors are connected to another power supply input of the power supply; if the power supply input connected to all odd-numbered input connectors fails, the other power supply input supplies power to n power modules connected to all odd-numbered input connectors, the n power modules including (n+1) power modules except the first power module; or if the power supply input connected to all even-numbered input connectors fails, the other power supply input supplies power to n power modules connected to all odd-numbered input connectors, the n power modules including (n+1) power modules except the second power module; or if one power module in the (n+1) power modules fails, the remaining n power modules supply power.

[0019] In a third aspect, an embodiment of the present application provides a computing device, the computing device comprising a power supply module and a load; the power supply module is configured to supply power to the load based on dual power supply inputs; the power supply module comprises (n+1) power supply modules and 2n input connectors; the input connectors are configured to connect to power supply sources and the power supply modules; the (n+1) power supply modules comprise (n-1) dual-input power supply modules and 2 single-input power supply modules; each dual-input power supply module comprises a first input port and a second input port, and the first input port and the second input port are connected to an input connector respectively; each single-input power supply module is connected to an input connector; wherein n is an integer greater than 1; when the 2n input connectors are connected to power supply inputs of power supply sources, the (n+1) power supply modules in the power supply module supply power.

[0020] The load comprises electronic components and the like in the computing device that need to be powered, such as a processor, a memory, a chip, and the like.

[0021] In combination with the third aspect, in a possible implementation, each dual-input power supply module receives two power supply inputs of the power supply sources, a first single-input power supply module of the 2 single-input power supply modules receives one of the two power supply inputs, and a second single-input power supply module of the 2 single-input power supply modules receives the other of the two power supply inputs.

[0022] In a possible implementation, when one of the power supply inputs fails, n power supply modules in the power supply module supply power, and the n power supply modules comprise power supply modules in the (n+1) power supply modules except the first single-input power supply module; when the other of the power supply inputs fails, n power supply modules in the power supply module supply power, and the n power supply modules comprise power supply modules in the (n+1) power supply modules except the second single-input power supply module.

[0023] In this way, when both of the two power supply inputs are normal power supply, the (n+1) power supply modules in the power supply module supply power. The two single-input power supply modules receive two independent power supply inputs, and in the case of failure of any one of the two power supply inputs, one single-input power supply module serves as a redundant power supply for the other single-input power supply module, thereby achieving reliable power supply.

[0024] In combination with the third aspect, in a possible implementation, the two single-input power modules include a first single-input power module and a second single-input power module, based on the positions of the 2n input connectors, the (n-1) double-input power modules are sequentially connected to the 1st input connector to the (2n-2)th input connector; the first single-input power module is connected to the (2n-1)th input connector; and the second single-input power module is connected to the 2nth input connector. In this way, the input connectors are sequentially connected according to the interface habits in the industry, and thus the last two input connectors are used as the input connectors for connecting the two single-input power modules. In the case where the power supply path connected to the last input connector fails, the n power modules in the power module group implement power supply, and in the case where both of the two power supply paths connected to the last two input connectors fail, only the (n-1) power modules in the power module group implement power supply. Here, the most possible connection mode is provided, which fully adapts to the interface habits of users and has practical universality.

[0025] In a possible implementation, all odd-numbered input connectors are connected to one power supply input of the power supply, and all even-numbered input connectors are connected to another power supply input of the power supply; if the power supply input connected to all odd-numbered input connectors fails, the other power supply input supplies power to the n power modules connected to all odd-numbered input connectors, and the n power modules include the power modules in the (n+1) power modules except the first power module; or if the power supply input connected to all even-numbered input connectors fails, the other power supply input supplies power to the n power modules connected to all odd-numbered input connectors, and the n power modules include the power modules in the (n+1) power modules except the second power module; or if one power module in the (n+1) power modules fails, the remaining n power modules supply power.

[0026] In combination with the third aspect, in a possible implementation, the power module group connects the 2n input connectors one by one to the 2n input lines to receive the power supply input of the power supply, and the load includes the processing device; and the processing device is configured to determine that the power module group is in a normal power supply state when it is detected that the 2n input lines are in place and the power supply is normal, and the first input port and the second input port of the (n-1) double-input power modules in the (n+1) power modules both have power supply input, and one input port of the two single-input power modules in the (n+1) power modules has power supply input. In this implementation, two power modules in the power module group receive single-input power supply, and the remaining power modules receive double-input power supply, and the power module group in this case is considered to be in a normal power supply state, without generating an alarm and normally supplying power to the load.

[0027] Optionally, the computing device records the identities of the two single-input power modules in the power module, and the processor is further configured to determine that the power module is in the normal power supply state based on the identities detecting that the two single-input power modules only receive one power supply input and that the other (n-1) power modules receive two power supply inputs.

[0028] Optionally, the computing device records the identities of the two single-input power modules in the power module, and the processor is further configured to determine that the power module is in the normal power supply state based on the identities detecting that the two single-input power modules only receive one power supply input and that the other (n-1) power modules receive two power supply inputs.

[0029] In a fourth aspect, an embodiment of the present application provides a whole cabinet, which includes a cabinet body, a power module, and a load. The power module and the load are arranged in the cabinet body of the whole cabinet. The cabinet body is connected with an external double-path power supply, and the power module is configured to supply power to the load based on the double-path power supply input.

[0042] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0043] The terms "first", "second", "third", and "fourth" and the like in the description and claims of the present application and the accompanying drawings are used to distinguish between similar objects, not to describe a particular sequential order. The terms "include" and "have" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a list of steps or units is not limited to the listed steps or units, but can optionally include additional steps or units not listed, or can optionally include additional steps or units inherent to such processes, methods, products, or apparatus.

[0044] The terms “component,” “module,” “system,” etc., used in this specification are used to refer to computer-related entities, hardware, firmware, combinations of hardware and software, software, or software in execution. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable file, an execution thread, a program, and / or a computer. As illustrated, applications running on terminal devices and terminal devices can both be components. One or more components may reside in a process and / or an execution thread, and components may be located on a single computer and / or distributed among two or more computers. Furthermore, these components can be executed from various computer-readable media on which various data structures are stored. Components can communicate, for example, via local and / or remote processes based on signals having one or more data packets (e.g., data from two components interacting with another component between a local system, a distributed system, and / or a network, such as the Internet interacting with other systems via signals).

[0045] Currently, many application areas require large-scale computing devices to perform data storage, data exchange, or data computation to achieve their respective functions.

[0046] The place where such large-scale computing equipment is placed and managed is usually called a data center or computer room. Specifically, a data center can be a central hub for various information technology (IT) applications such as data computing, network transmission, and data storage. It can have a series of environmental conditions such as a high-speed and reliable internal and external network environment, systematic monitoring support methods, and large-scale site and computer room facilities, enabling unified operation and maintenance management of IT infrastructure, business applications, and data.

[0047] like Figure 1 As shown, Figure 1 An exemplary data center 100 is illustrated, comprising a computer room 101, one or more computer racks 102, a power supply 103, and a power supply 104. The computer racks 102 can house multiple computing / network devices, such as servers, switches, etc. The power supply 103 or 104 supplies power to the computing devices housed in the computer racks 102. Exemplarily, the power supply 103 or 104 can provide alternating current (AC) and / or direct current (DC).

[0048] In some embodiments, power supply 103 and power supply 104 are two independent inputs, and each computer rack 102 can receive one or two inputs.

[0049] In some embodiments, Figure 1The power supply system of the data center 100 shown in the figure can be a 2n system (also referred to as an n+n system), where n represents mains. That is, the power supply 103 and the power supply 104 provide two independent mains, and the power supply 103 and the power supply 104 can also be referred to as a primary power system (main power input) and a secondary power system (backup power input) respectively. Both of the two power supplies are connected to the computing device, and when one power input fails, the computing device can automatically switch to the other power input to supply power to the computing device. In this way, the power supply stability of the data center 100 is improved. The two inputs provided by the power supply 103 and the power supply 104 can also be referred to as A input and B input in the embodiments of the present application.

[0050] In some embodiments, the power supply system of the data center 100 can also be an n+1 system, where n+1 is one mains plus one generator, and two power supplies are also connected to the computing device; in some embodiments, the power supply system of the data center 100 can also be a 2n+1 system, where 2n+1 is two mains plus a generator as backup, and two power supplies are connected to the computing device, and the generator is additionally provided as a backup power supply.

[0051] Next, the specific structure configuration in the computer rack in the computer rack 102 in the above data center 100 is exemplarily described. As shown in Figure 2 Figure 2 Exemplarily, a front view (left) and a back view (right) of a computer rack 102 are shown, and three servers are exemplarily placed in the computer rack 102, which are server 201, server 202 and server 203. The computer rack 102 is configured with a power distribution column head cabinet 211 and a power distribution column head cabinet 212, wherein the power distribution column head cabinet 211 and the power distribution column head cabinet 212 are respectively connected to one power input. The power distribution column head cabinet 211 and the power distribution column head cabinet 212 are close to the power-consuming equipment and are used to provide power for the power-consuming equipment (such as the server 201, the server 202 and the server 203). It can be seen from the above FIG. 1 that the power supply 103 and the power supply 104 are respectively connected to two power distribution column head cabinets of each computer rack 102 to provide two power inputs for each computer rack 102. Exemplarily, Figure 2 The A input (power supply 103) is provided to the power distribution column head cabinet 212, and the B input (power supply 104) is provided to the power distribution column head cabinet 211.

[0052] Among them, Figure 2 The power distribution column head cabinets 211 and 212 shown in the figure are each configured with 7 power supply interfaces 213 for connection with power-consuming equipment.

[0053] The server includes a plurality of power supply interfaces 214, for example Figure 2 ​The server 201 shown includes 12 power interfaces 214, while servers 202 and 203 each include 2 power interfaces 214. Connecting the power interfaces 214 and the power supply interface 213 establishes the electrical connection between the server and the power supply.

[0054] In this embodiment, the power interface 214 can also be referred to as an input connector. The input connector is used to provide a connection between the power supply module and the power supply.

[0055] In some embodiments, the server can be configured with various types of power supply configurations, such as:

[0056] Configuration 1: n power supply configuration, meaning the server can operate normally with n power supply modules, and the configuration specifies n power supply modules. Without backup power, if one power supply module fails, the power supply to the remaining n-1 power supply modules will be insufficient, affecting service operation and making it difficult to guarantee power supply reliability.

[0057] For example, the power configuration in servers 202 and 203 is a power configuration with n=1, where the two power interfaces are two interfaces of one power module, that is, the power type in the power module is a dual-input power supply. Figure 2 The two power interfaces in server 202 (and similarly in server 203) are framed together, indicating that the two power interfaces belong to the same power module.

[0058] Configuration Option 2: n+n power supply configuration. This means the server can operate normally with n power supply modules, but the configuration actually includes 2n power supply modules, with the n modules serving as redundant backups. The data center provides two power inputs, each connected to n power supply modules. If one power supply fails, the other power supply can still provide the necessary power for normal operation. In this case, each power supply module is connected to one power input, and the power supply type can be a single-input power supply.

[0059] For example, such as Figure 3 As shown, Figure 3 The diagram illustrates a 5+5 power supply configuration, meaning five power supplies serve as backups. The server has a power consumption of 15kW, with each power module providing 3kW. The data center provides five branches of input A and five branches of input B, totaling ten input branches corresponding to each power module. Inputs A and B are independent of each other. If input A fails, input B can still provide 3kW * 5 = 15kW of power to the server. If one power supply fails, the remaining nine power supplies provide 3kW * 9 = 27kW of power to the server. Service is unaffected in the event of a power failure in either input A or input B, or a failure of one power module, ensuring power supply reliability.

[0060] However, the above configuration mode two, in the case of input not power down, theoretically maximum can provide 3kw*10=30kw power supply capacity to the server, but the server has only 15kw, there is a huge waste of cost, and at the same time occupies the internal space of the server, affects the space density inside the server.

[0061] Configuration form three: n+1 power supply configuration, indicates that the server has n power module can work normally, but in the configuration is n+1 power module, one of which is as a redundant power backup. Data center provides two power supply input, each power supply input connection n+1 power module, when a power supply failure, also can through the other power supply to provide the power required for normal work. In this case, each power module needs to connect two power supply input, power supply type is double input power supply.

[0062] Exemplary, as shown in Figure 4 , Figure 4 5+1 power supply configuration form is shown, that is, one power supply as backup. Server power 15kw, each power module 3kw, data center provides A input 6 branch and B input 6 branch respectively, a total of 12 branch input corresponding to each power module, wherein A and B are independent of each other. If A power down, B can provide 3kw*6=18kw power supply capacity; 1 power failure, there are 3kw*5=15kw power supply capacity. In the case of A or B one of the power down or one of the power module failure, the business is not affected, which ensures the reliability of power supply. And, compared with 5+5 power supply configuration form, the number of power supply from 10 to 6, the cost decreases by 40%, while greatly saving the internal space of the server.

[0063] In practical applications, some computer racks with high configuration requirements can receive 2n backup power supplies, some computer racks can receive n+1 backup power supplies, and some computer racks can receive parallel power supply from one or more separate power supplies. It can be expensive and time-consuming to configure each rack with a specific type of power redundancy using support from a specific power system, because each configuration can require specific configuration of specific upstream systems and components to establish matching power support redundancy for the computer rack.

[0064] It can be seen that the above configuration form three phase compared to configuration form two, can reduce the number of power supply in the same reliability, however, the configuration form three required branch configuration form two required branch more two. For example, the above 5+1 power supply configuration form needs A input 6 branch and B input 6 branch, a total of 12 branch input corresponding to each power module, i.e. n+1 power supply configuration form needs 2(n+1) branch input; and 5+5 power supply configuration form needs A input 5 branch and B input 5 branch, a total of 10 branch input corresponding to each power module, i.e. n+n power supply configuration form needs 2n branch input.

[0065] In some scenarios, in combination with the above Figure 2 It is illustrated that the computer rack 102 is configured with dual power supply input distribution column head cabinet 211 and distribution column head cabinet 212, wherein the distribution column head cabinet 211 and the distribution column head cabinet 212 respectively provide 7 power supply interfaces. The server 202 includes 2 power supply interfaces, which need to be respectively inserted into one power supply interface of the distribution column head cabinet 211 and the distribution column head cabinet 212. The server 203 also includes 2 power supply interfaces, which need to be respectively inserted into one power supply interface of the distribution column head cabinet 211 and the distribution column head cabinet 212. For the server 201, the server 201 has 12 power supply interfaces, which need to be respectively inserted into 6 power supply interfaces of the distribution column head cabinet 211 and the distribution column head cabinet 212. However, the distribution column head cabinet 211 and the distribution column head cabinet 212 only have 7 power supply interfaces respectively, after connecting the server 202 and the server 203, each only has 5 power supply interfaces for the server 201 to connect.

[0066] In this case, if you want to make the server 201, the server 202 and the server 203 work normally, you need to add two distribution column head cabinets to the computer rack 102, which respectively provide one power supply interface for the server 201. Generally, each distribution column head cabinet has more than one power supply interface, and the two added distribution column head cabinets have low utilization rate. And each distribution column head cabinet needs to be connected to a power supply input, for example, the distribution column head cabinet 212 is connected to the A input (power supply 103), and the distribution column head cabinet 211 is connected to the B input (power supply 104). If two new distribution column head cabinets are added, the two distribution column head cabinets need to be connected to the power supply 103 and the power supply 104 respectively. That is, the power supply 103 and the power supply 104 need to provide one branch respectively.

[0067] However, generally, the configuration of each data center 100 is specific. Due to specific systems and components, changing the configuration of a specific group of computing devices can be time-consuming and expensive, such as adding power supply lines, interfaces; installing a new power distribution column head cabinet; providing connection lines for the power supply and the new power distribution column head cabinet, and connection lines for the new power distribution column head cabinet and the computing devices, and so on. Such changes can require various system and component configurations to be added, removed, and so on, and can involve changes to the floor space, wall space, and so on of the data center 100; and even reconfiguration of various systems and components in the data center 100 can require certain systems and components to be temporarily offline, i.e., the computing units can also need to be taken offline to implement changes in specific systems and components, thereby increasing the cost of the modification.

[0068] Embodiments of the present application provide a power module, which is in the form of an n+1 power supply configuration, and which can support 2n branch power supply inputs. In this way, in the case where the existing configuration of a data center does not support, for example, the number of interfaces of the power supply and the power distribution column head cabinet is insufficient, and modification of the computer room is required, 2n branch power supply inputs can be used to save the interfaces of the power supply and the power distribution column head cabinet, and to avoid modification of the computer room.

[0069] The power module can be applied to any electronic device that needs to be powered, and the electronic device can specifically be a computer device or a storage device, a wireless device, a network device, and so on. In the following, a server 201 is taken as an example. In the example described above Figure 2 The server 201 has 12 input connectors and needs to be connected to 6 power supply interfaces of the power distribution column head cabinet 211 and the power distribution column head cabinet 212 respectively. However, the power distribution column head cabinet 211 and the power distribution column head cabinet 212 each only have 7 power supply interfaces, and after the server 202 and the server 203 are connected, each only has 5 power supply interfaces left for the server 201 to be connected, which is insufficient to support normal access of the server 201. Based on the power module provided in embodiments of the present application, the server 201 only needs to be connected to 10 power supply interfaces, and the power module can realize reliable power supply for the server 201.

[0070] Referring to a structural schematic diagram of a power module shown in Figure 5 The power module includes (n+1) power modules, of which 2 are single-input power modules and (n-1) are double-input power modules. The single-input power module includes one input connector and one power supply. The power supply is a device that converts alternating current into stable direct current through a power transformer and provides power to a load; the input connector is used to connect the power module and an external power supply to enable the power module to receive power supply input from the external power supply.

[0071] The dual-input power module includes two input connectors, one power supply and a dual-path switch, each power supply includes two ports, one of which is connected to the corresponding dual-path switch, and the other is connected to the load for power supply. The single-input power module includes one input connector and one power supply, one port of which is connected to the input connector, and the other port is connected to the load for power supply. Among them, the load can be any device, electronic components, etc. that needs power supply, such as computing devices such as servers, switching devices such as switches, routers, electronic components such as processors, chips, etc. Among them,

[0072] The input of the dual-path switch is dual-path, which can be A-path input and B-path input. The A-path input and the B-path input are connected to the dual-path switch through the input connector respectively. The dual-path switch can automatically switch the input to the other path when any one of the dual-path inputs is powered off, avoiding the impact of power failure on the load.

[0073] In some embodiments, the dual-path switch can set one of the inputs, for example, the A-path input, as the default power supply. The power supply can generally supply power to the load based on the default power supply. When the default power supply is powered off, the dual-path switch immediately switches the input to the B-path input. Optionally, when the default power supply such as the A-path input resumes power supply, the dual-path switch can also switch the input back to the default power supply.

[0074] Specifically, the structure of the dual-path switch can integrate a break before make (sts) switch, or can combine the ac into dc, and only one of the A and B paths has power, and the power supply can work normally.

[0075] As shown in the left graph in FIG. 1, Figure 6 Figure 6 The left graph in FIG. 1 is a sts static switch that can realize uninterrupted switching between different power supplies. The ac / dc is an ac / dc power converter with ac input and dc output; the ac / dc converter uses a rectifier diode on the secondary side to rectify the high-frequency ac voltage, then smoothes it with a capacitor, and then converts it to a set dc output voltage. In some embodiments, in the normal working state, the default power supply supplies power to the load when the default power supply is within the normal voltage range. When the default power supply fails, it automatically switches to the backup power supply. When the default power supply resumes normal operation, it automatically switches back to the default power supply.

[0076] Figure 6 ​In the right graph in FIG. 1, dc / dc is a power converter with input of direct current and output of direct current; the dc / dc converter can convert electric energy of one voltage value into electric energy of another voltage value in a direct current circuit. The dual-conversion switch receives two inputs, and the input electric energy is converted into direct current through the ac / dc converter, and then the two-way dc electric energy is combined through the dc / dc converter to output electric energy of a preset voltage value. When one of the power supply sources fails, the output of the dual-conversion switch is not affected.

[0077] In some embodiments, the power module 303 described above can be integrated, specifically, the dual-conversion switch can be integrated in the power supply, which can reduce the assembly operation and improve the assembly efficiency on the one hand, and can reduce the volume of the power module and save space on the other hand. Moreover, integrating the dual-conversion switch in the power supply can protect the dual-conversion switch.

[0078] In some embodiments, the dual-conversion switch can not be arranged in the power module, but can be arranged in the server 201.

[0079] In some embodiments, the input connector and the power supply can be independent of each other, and the power supply and the input connector can be connected through a PCB board and / or a back plate. The connection mode can include a cable or a copper strip and the like.

[0080] In some embodiments, the power module described above can be integrated, for example, as shown in FIG. 1, Figure 7 Figure 7 FIG. 1 shows an exemplary power module including four single-input power modules. As can be seen in FIG. 1, Figure 7 In FIG. 1, the power supply and the input connector in each of the four power modules are fixedly connected in a shell, that is, the power supply and the input connector are not detachably connected. The power module provided in the embodiments of the present application can also be integrated, including two single-input power modules and (n-1) dual-input power modules, which can support 2n branch power supply inputs.

[0081] The following will be described in detail with specific examples, Figure 8 ​A power supply module group is shown in a power supply configuration form of 5+1 configuration, n is 5. Six power supply modules and ten input connectors are included in FIG. 8, the six power supply modules include four double-input power supply modules and two single-input power supply modules, wherein one double-input power supply module is connected by every two input connectors of eight input connectors (input connector 1-input connector 8), and one single-input power supply module is connected by two input connectors (input connector 11 and input connector 12). Each double-input power supply module receives two power supply inputs (A input and B input) by connecting two input connectors, and each single-input power supply module receives one power supply input by connecting one input connector. Wherein, input connector 1, 3, 5, 7 are connected to one input port of four double-input power supply modules 1, 2, 3, 4 respectively; input connector 2, 4, 6, 8 are connected to another input port of four double-input power supply modules 1, 2, 3, 4 respectively; single-input power supply module 5 receives A input by connecting input connector 9; single-input power supply module 6 receives B input by connecting input connector 10.

[0082] In such a connection mode, input connector 1, 3, 5, 7, 9 is connected to A input, and input connector 2, 4, 6, 8, 10 is connected to B input; in this case, if the server power is 15kw, each power supply module is 3kw, and the data center provides five branches of A input and five branches of B input, totaling ten branches of input corresponding to each power supply module, wherein a and b are independent of each other.

[0083] It can be seen that single-input power supply module 5 and single-input power supply module 6 only receive one input, Figure 8 In the above-mentioned embodiment, single-input power supply module 5 receives A input, and single-input power supply module 6 receives B input. Under normal power supply conditions, six power supply modules can provide 3kw*6=18kw power supply capacity. And at this time, six power supply modules are only connected to ten branches, saving two interfaces of the power distribution column cabinet.

[0084] Under abnormal power supply conditions, for example, if A input is powered off, five power supply modules (power supply module 1, 2, 3, 4, 6) of B input can also provide 3kw*5=15kw power supply capacity; for example, if B input is powered off, five power supply modules (power supply module 1, 2, 3, 4, 5) of A input can also provide 3kw*5=15kw power supply capacity; for example, if one power supply module is faulty, the remaining five power supply modules have 3kw*5=15kw power supply capacity. In the case of one of a or b being powered off or one of the power supply modules being faulty, the service is not affected, ensuring the reliability of power supply.

[0085] It is understandable that there are many ways to connect the power module and the input connector, and this application embodiment does not limit this.

[0086] Among them, the above Figure 9 Taking the connection method of n+1 power modules (n is 5) and input connectors in server 201 as an example, the connection method between the external power distribution cabinet and server 201 is shown below. Figure 10 As shown, server 201 includes 10 input connectors (from left to right, the first input connector corresponds to the tenth input connector). Figure 10 Input connectors 1 to 10 (input connectors).

[0087] Generally speaking, for a server 201 with a (5+1) power supply configuration, 12 input connectors are needed to receive dual power inputs, with each power input providing 6 branches, meaning a total of 12 power interfaces are required. It can be seen that when both servers 202 and 203 are normally connected to the power supply, power distribution cabinets 211 and 212 each have 5 power interfaces remaining, which is insufficient to support the normal connection of server 201. However, this application embodiment designs a power module with a (5+1) power supply configuration but only 10 input connectors. This power module is mounted on server 201, and the connection method between the power module and the input connectors is as follows... Figure 9 As shown, simply connecting these 10 input connectors to the power supply will still enable normal and reliable power supply.

[0088] This application provides a power module with an n+1 power configuration, comprising (n-1) dual-input power modules and two single-input power modules. The (n+1) power modules require 2n input connectors, where each of the (n-1) dual-input power modules has two input connectors, and each of the two single-input power modules has one input connector. Even with 10 branch power inputs, the (n+1) power modules can still provide normal and reliable power to the server 201. That is, the n+1 configured power module can support 2n branch power inputs.

[0089] In some embodiments, the plurality of input connectors can be marked with sequence numbers on the display to indicate the user to connect with the power supply in sequence. For example, the sequence numbers of each input connector are marked on the cabinet of the server 201. If the sequence numbers start from 1, the input connector with the number 1 is the input connector 1 in the embodiments of the present application, the input connector with the number 2 is the input connector 2 in the embodiments of the present application, and so on. If the sequence numbers start from 0, the input connector with the number 0 is the input connector 1 in the embodiments of the present application, the input connector with the number 1 is the input connector 2 in the embodiments of the present application, and so on. If the sequence numbers start from a, the input connector with the number a is the input connector 1 in the embodiments of the present application, the input connector with the number b is the input connector 2 in the embodiments of the present application, and so on.

[0090] The above describes the power supply configuration form of n+1, and the connection and power supply situation in the case of n being 5. For any n value, the connection mode of the embodiments of the present application can be used.

[0091] As shown in FIG. 1, Figure 10 Figure 10 The (n+1) power supply modules include (n-1) double-input power supply modules and 2 single-input power supply modules. Each double-input power supply module includes a first input port and a second input port, and the first input port and the second input port are respectively connected to an input connector. Each single-input power supply module is connected to an input connector. n is an integer greater than 1. When the 2n input connectors are connected to the power input of the power supply, the (n+1) power supply modules in the power supply module realize power supply.

[0092] The power supply module provided by the embodiments of the present application is in the form of n+1 power supply configuration, and can support 2n branch power inputs. In this way, in the case that the existing data center configuration does not support, for example, the number of interfaces of the power supply and the power distribution column cabinet is insufficient, and the case that the machine room needs to be transformed, 2n branch power inputs can be used to save the interfaces of the power supply and the power distribution column cabinet. In this way, the machine room transformation is avoided, and the normal power supply is not affected.

[0093] In a possible implementation, each double-input power supply module receives two power inputs of the power supply, the first single-input power supply module of the 2 single-input power supply modules receives one of the two power inputs, and the second single-input power supply module of the 2 single-input power supply modules receives the other of the two power inputs.

[0094] ​In a possible implementation, when one power supply input fails, n power modules in the power module group supply power, the n power modules including (n+1) power modules except the first single-input power module; when another power supply input fails, n power modules in the power module group supply power, the n power modules including (n+1) power modules except the second single-input power module.

[0095] In this connection mode, when both power supply inputs are normal, (n+1) power modules in the power module group supply power. Two single-input power modules receive two independent power supply inputs, and in the case of failure of any one of the two power supply inputs, one single-input power module serves as a redundant power supply for the other single-input power module to realize reliable power supply.

[0096] In a possible implementation, the two single-input power modules include a first single-input power module and a second single-input power module, and based on the positions of the 2n input connectors, (n-1) double-input power modules are connected to the 1st input connector to the (2n-2)th input connector in sequence; the first single-input power module is connected to the (2n-1)th input connector; and the second single-input power module is connected to the 2nth input connector. In accordance with the industry common interface habit, the input connectors are connected in sequence, and therefore the last two input connectors serve as input connectors for connecting the two single-input power modules. In the case of failure of the power supply path connected to the last input connector, n power modules in the power module group supply power, and in the case of failure of both power supply paths connected to the last two input connectors, only (n-1) power modules in the power module group supply power. Here, the most possible connection mode is provided, which fully adapts to the interface habit of users and has practical applicability.

[0097] In a possible implementation, all odd-numbered input connectors are connected to one power supply input of a power supply, and all even-numbered input connectors are connected to another power supply input of the power supply; if the power supply input connected to all odd-numbered input connectors fails, the other power supply input supplies power to n power modules connected to all odd-numbered input connectors, the n power modules including (n+1) power modules except the first power module; or if the power supply input connected to all even-numbered input connectors fails, the other power supply input supplies power to n power modules connected to all odd-numbered input connectors, the n power modules including (n+1) power modules except the second power module; or if one power module in the (n+1) power modules fails, the remaining n power modules supply power.

[0098] As Figure 10As shown, when 2n input connectors access power supply input, (n+1) power supply modules in the power supply module implement power supply. If one of the power supply inputs connected by the odd-numbered input connectors fails, the other power supply input connected by the even-numbered input connectors provides power for the n power supply modules connected by the even-numbered input connectors; if one of the (n+1) power supply modules fails, the remaining n power supply modules provide power.

[0099] As can be seen, the input connector (2n-1) is connected to the single-input power supply module n, and the input connector 2n is connected to the single-input power supply module (n+1); the single-input power supply module n and the single-input power supply module (n+1) receive 1 input, Figure 10 In the above, the power supply module n receives the A input, and the power supply module (n+1) receives the B input. Under normal power supply conditions, the (n+1) power supply modules can provide power supply capability. Under abnormal power supply conditions, for example, if the A input is powered off, the n power supply modules (the double-input power supply modules 1, 2, …, n-1 and the single-input power supply module n+1) of the B input can also provide power supply capability; for example, if the B input is powered off, the n power supply modules (the double-input power supply modules 1, 2, 3, n-1 and the single-input power supply module n) of the A input can also provide power supply capability; for example, if one power supply fails, the remaining n power supplies have power supply capability. In the case that one of the A or B inputs is powered off or one of the power supply modules fails, the service is not affected, ensuring the reliability of power supply.

[0100] The power supply module provided by the embodiments of the present application can be applied to any electronic device requiring a power supply module, and the electronic device can be a computer device or a storage device, a wireless device, a network device, etc. The embodiments of the present application do not make any limitation on the specific form of the electronic device.

The electronic device can be used to implement the functions of the above electronic device. Figure 11 Figure 11 As shown in FIG. 13, it is a hardware structure schematic diagram of an electronic device provided by an embodiment of the present application. The electronic device can be used to implement the functions of the above electronic device.

[0103] Figure 11 As shown in FIG. 13, the electronic device 200 can include a processor 210, a memory 220, a power module 250, a communication interface 230 and a bus 240. The processor 210, the memory 220, the power module 250 and the communication interface 230 can be connected through the bus 240.

[0104] The processor 210 can include one or more processing units, for example: the processor 210 can include a central processing unit CPU, an application processor ap, a modem processor, a graphics processing unit gpu, an image signal processor isp, a controller, a memory, a video codec, a digital signal processor dsp, a baseband processor, a baseboard management controller BMC, a system management module SMM and / or a neural-network processing unit npu, etc. Among them, different processing units can be independent devices, or can be integrated in one or more processors. Among them, the controller can be the nerve center and command center of the electronic device 200. The controller can generate operation control signals according to instruction operation codes and timing signals to complete the control of fetching instructions and executing instructions.

[0105] ​The memory 220 can be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited thereto.

[0106] In some embodiments, the memory 220 can exist independently of the processor 210. The memory 220 can be connected to the processor 210 through the bus 240 for storing data, instructions, or program codes. When the processor 210 invokes and executes the instructions or program codes stored in the memory 220, the video processing method provided by the embodiments of the present application can be implemented. In some embodiments, the memory 220 can also be integrated with the processor 210.

[0107] The communication interface 230 is configured to connect the electronic device 200 to other devices through a communication network, which can be an Ethernet network, a radio access network (RAN), a wireless local area network (WLAN), or the like. The communication interface 230 can include a receiving unit configured to receive data, and a transmitting unit configured to transmit data.

[0109] The power module 250 is configured to receive a dual power input provided by a power supply, and then supply power to the loads (including the processor 210, the memory 220, the communication interface 230, and the like) of the electronic device 200 based on the dual power input. The specific description of the power module 250 can include the related description of the power module in the above embodiments, which will not be repeated here.

[0110] In some embodiments, the power module 250 is connected to 2n input lines via 2n input connectors to receive power input from an external power source. The processor 210 determines that the power module 250 is in a normal power supply state when it detects that the power module 250 is connected to 2n input lines and is powered normally, and that the first and second input ports of (n-1) out of (n+1) power modules have power input, and one input port of two out of (n+1) power modules has power input. Typically, for a dual-input power supply, receiving two power inputs is considered normal power supply; for a single-input power supply, receiving one power input is considered normal power supply. In this implementation, the power module 250 receives power input from 2n branches, and in this case, the power module 250 is considered to be in a normal power supply state, without generating an alarm and supplying power to the load normally.

[0111] Optionally, the electronic device 200 records the identifiers of two single-input power modules in the power module 250. The processor 210 is used to detect, based on the identifiers, that the two single-input power modules receive only one power input, and the other (n-1) power modules besides the two power modules receive two power inputs, then the power module 250 is determined to be in a normal power supply state.

[0112] Optionally, the electronic device 200 records the identifiers of two single-input power modules in the power module 250. The processor 210 is used to detect, based on the identifiers, that the two single-input power modules receive only one power input, and that one of the two single-input power modules receives one power input from the power supply, while the other single-input power module receives the other power input from the power supply. If the other (n-1) power modules besides the two single-input power modules receive two power inputs, then the power module 250 is determined to be in a normal power supply state.

[0113] It should be pointed out that, Figure 11 The structure shown does not constitute a limitation on the electronic device 200, except... Figure 11 In addition to the components shown, the electronic device 200 may include more or fewer components than shown, or combine certain components, or have different component arrangements.
