Power module and power supply method

Technical Field

Background

With the development of computing technology, the size of a data center is larger and larger, and the requirements of enterprises on the density, the cost and the energy efficiency of a power supply system are higher and higher. Many application fields need to realize corresponding functions through operations such as data storage, data exchange or data calculation of large-scale computing equipment. The place where the large-scale computing equipment is placed and managed is often referred to as a data center or computer room. The power supply of the computing device serves to supply power to the load of the computing device, ensuring proper operation of the load. The existing power supply of the computing equipment usually adopts the design of a redundant power supply so as to improve the reliability of the computing equipment and ensure the normal power supply of the computing equipment.

Generally, the configuration of each data center is specific. Because the computing equipment that a data center can accommodate is also fixed due to the particular systems and components, it is very time consuming and expensive to want to change the configuration of the data center.

Disclosure of Invention

Detailed Description

The embodiments of the present application will be described below with reference to the drawings.

The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

As used in this specification, the terms "component," "module," "system," and the like are intended to refer to a computer-related entity, either hardware, firmware, a combination of hardware and software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a terminal device and the terminal device can be a component. One or more components can reside within a process and/or thread of execution and a component can be localized on one computer and/or distributed between 2 or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from two components interacting with another component in a local system, distributed system, and/or across a network such as the internet with other systems by way of the signal).

At present, a large number of application fields need to realize corresponding functions through operations such as data storage, data exchange or data calculation of large-scale computing equipment.

The place where the large-scale computing equipment is placed and managed is often referred to as a data center or computer room. Specifically, the data center may be a center for providing information technology (it) application services such as data computation, network transmission, and data storage, and may have a high-speed and reliable internal and external network environment, a systematic monitoring support means, and a series of environmental conditions such as large-scale site and machine room facilities, and may implement unification and operation and maintenance management of it infrastructure, service application, and data.

As shown in fig. 1, fig. 1 exemplarily illustrates a data center 100, where the data center 100 includes a computer room 101, one or more computer racks 102, a power supply 103, and a power supply 104. Wherein multiple computing/networking devices, such as servers, switches, etc., may be disposed in the computing rack 102. The power supply 103 or the power supply 104 is used to power computing devices disposed in the computing rack 102. For example, the power supply 103 or the power supply 104 may provide alternating current (ac) and/or direct current (dc).

In some embodiments, the power supply 103 and the power supply 104 are separate two-way inputs, and each computer rack 102 may receive one or two inputs.

In some embodiments, the power supply system of the data center 100 shown in fig. 1 may be a 2n system (also referred to as an n + n system), where n represents the utility power. That is, the power supply 103 and the power supply 104 provide two independent commercial power, and the power supply 103 and the power supply 104 may also be referred to as a primary power system (main power input) and a secondary power system (backup power input), respectively. The two power supply sources are connected to the computing equipment, and when one power supply input fails, the computing equipment can be automatically switched to the other power supply input to supply power to the computing equipment. In this way, the power supply stability of the data center 100 is improved. In the embodiment of the present application, the two inputs provided by the power supply 103 and the power supply 104 may also be referred to as an a input and a B input, respectively.

In some embodiments, the power supply system of the data center 100 may also be an n +1 system, where n +1 is one line of commercial power plus one line of generator, and is two power supplies connected to the computing device; in some embodiments, the power supply system of the data center 100 may also be a 2n +1 system, where 2n +1 is two mains supplies and an additional generator as a backup, and is used for connecting two power supplies to the computing device, and the generator is used as a backup power supply.

Next, taking the computer rack 102 in the data center 100 described above as an example, a specific structural configuration in the computer rack is exemplified. As shown in fig. 2, fig. 2 exemplarily shows a front schematic view (left) and a back schematic view (right) of a computer rack 102, in which three servers, namely, a server 201, a server 202 and a server 203 are exemplarily disposed in the computer rack 102. 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 with a power supply input. The distribution column head cabinet 211 and the distribution column head cabinet 212 are installed near the electric devices and are used for providing power for the electric devices (such as the server 201, the server 202 and the server 203). As can be seen from fig. 1, the power supply 103 and the power supply 104 are respectively connected to the two power distribution column headers of each of the computing racks 102, and provide two power inputs to each of the computing racks 102. Illustratively, in fig. 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.

The power distribution column head cabinet 211 and the power distribution column head cabinet 212 shown in fig. 2 are each configured with 7 power supply interfaces 213 for connecting to electrical devices.

The server includes a plurality of power interfaces 214, for example, the server 201 shown in fig. 2 includes 12 power interfaces 214, and the server 202 and the server 203 each include 2 power interfaces 214. The power interface 214 and the power interface 213 are connected, that is, the server and the power supply are electrically connected.

In the embodiment of the present application, the power interface 214 may also be referred to as an input connector. The input connector is used for providing connection between the power supply module and the power supply.

In some embodiments, the server may be configured with various types of power configurations, such as:

the configuration form I is as follows: and n power supply configurations, which indicate that the server can normally work by n power supply modules, and the configuration of the server is n power supply modules. If there is no backup power supply, then under the condition that 1 power supply module has a fault, the power supply of n-1 power supply modules is insufficient, thereby affecting the service implementation and being difficult to ensure the power supply reliability.

Illustratively, the power configurations in the server 202 and the server 203 are power configurations with n being 1, and 2 power interfaces thereof are two interfaces of 1 power module, that is, the power type in the power module is dual-input power. In fig. 2, 2 power interfaces in the server 202 (the same applies to the server 203) are boxed together, which shows that the 2 power interfaces are power interfaces of the same power module.

Configuration form two: the n + n power supply configuration indicates that the server has n power supply modules which can normally work, but the configuration is 2n power supply modules, wherein the n power supply modules are used as redundant power supply backups. The data center provides two paths of power supply inputs, each path of power supply input is connected with the n power supply modules, and when one path of power supply fails, the power supply module can also provide power required by normal work through the other path of power supply. In this case, each power module is connected to one power supply input, and the power type may be a single input power supply.

Illustratively, as shown in FIG. 3, FIG. 3 shows a 5+5 power configuration, i.e., there are 5 power supplies as a backup. The power of the server is 15kw, each power supply module is 3kw, the data center provides an A path input 5 branch and a B path input 5 branch respectively, and 10 total branch inputs correspond to each power supply module, wherein the A path and the B path are independent. If the path A is powered off, the path B can still provide power supply of 3kw × 5=15kw for the server; if 1 power supply fails, the remaining 9 power supplies have power supply of 3kw × 9=27kw to the server. Under the condition that 1 of the paths A or B is in power failure or 1 of the paths B is in fault, the service is not influenced, and the power supply reliability is ensured.

However, in the second configuration, in the case that the input is not powered down, theoretically, the maximum power supply capacity of 3kw × 10=30kw can be provided to the server, but the server is only 15kw, which causes huge cost waste, and at the same time, the space inside the server is occupied, which affects the space density inside the server.

The configuration form is three: the n +1 power supply configuration indicates that the server has n power supply modules which can work normally, but the configuration is n +1 power supply modules, and one of the power supply modules is used as a redundant power supply backup. The data center provides two paths of power supply inputs, each path of power supply input is connected with n +1 power supply modules, and when one path of power supply fails, the power supply module can also provide power required by normal work through the other path of power supply. In this case, each power module needs to be connected with two power supply inputs, and the power type is a dual-input power supply.

Illustratively, as shown in FIG. 4, FIG. 4 shows a power configuration of 5+1, i.e., there are 1 power supply as a backup. The power of the server is 15kw, each power supply module is 3kw, the data center provides an A path input 6 branch and a B path input 6 branch respectively, and total 12 branch inputs correspond to each power supply module, wherein the A path and the B path are independent. If the A path is powered down, the B path can provide 3kw x 6=18kw power supply capacity; with 1 power supply failure, there is a power supply capacity of 3kw × 5=15kw. Under the condition that 1 of the paths A or B is in power failure or 1 of the paths B is in fault, the service is not influenced, and the power supply reliability is ensured. Compared with the power supply configuration mode of 5+5, the configuration mode has the advantages that the number of power supplies is reduced from 10 to 6, the cost is reduced by 40%, and meanwhile, the internal space of the server is greatly saved.

In practical applications, some computing racks with servers having high configuration requirements may receive 2n backup power supplies, some computing racks may receive n +1 backup power supplies, and some computing racks may receive parallel power from one or more separate power supplies. Configuring each rack for a particular type of power redundancy with support from a particular power system may be expensive and time consuming, as each configuration may require a particular configuration of particular upstream systems and components to establish a matching power support redundancy for the computing rack.

It can be seen that the third configuration can reduce the number of power supplies compared to the second configuration with the same reliability, but the third configuration requires two more branches than the second configuration. For example, the power configuration form of 5+1 requires an a-path input 6 branch and a B-path input 6 branch, and a total of 12 branches of inputs correspond to each power module, that is, a branch input of 2 (n + 1) is required in the power configuration form of n + 1; while 5+5 requires 5 branches for input a and 5 branches for input B, and 10 branches for total input correspond to each power module, i.e. 2n branches for input n + n.

In some scenarios, as described above in connection with fig. 2, the computer rack 102 is configured with a dual power input 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 each provide 7 power supply interfaces. Server 202 includes 2 power interfaces, and a power supply interface that needs to be inserted into power distribution column head cabinet 211 and power distribution column head cabinet 212, respectively, and server 203 also includes 2 power interfaces, and a power supply interface that needs to be inserted into power distribution column head cabinet 211 and power distribution column head cabinet 212, respectively. For the server 201, the server 201 has 12 power interfaces, and 6 power interfaces respectively inserted into the power distribution column head cabinet 211 and the power distribution column head cabinet 212 are required. However, the power distribution column head cabinet 211 and the power distribution column head cabinet 212 have only 7 power supply interfaces, and after the server 202 and the server 203 are connected, only 5 power supply interfaces are left for the server 201 to connect.

In this case, if it is desired to make the server 201, the server 202 and the server 203 all work normally, two power distribution column head cabinets which provide one more power supply interface for the server 201 are added to the computer rack 102. Generally, each power distribution column head cabinet has more than one power supply interface, and the two power distribution column head cabinets added have lower utilization rate. Moreover, each first power distribution column cabinet needs to be connected to one power supply input, for example, the first power distribution column cabinet 212 is connected to the a input (power supply 103), and the first power distribution column cabinet 211 is connected to the B input (power supply 104). If two power distribution column head cabinets are newly added, the two power distribution column head cabinets need to be connected with the power supply 103 and the power supply 104 respectively. Namely, the power supply 103 and the power supply 104 need to provide a branch.

However, in general, the configuration of each data center 100 is specific. Due to the particular systems and components, changing the configuration of a particular computing device group can be time consuming and expensive, for example, for increased power supply lines, interfaces; installing a newly-added power distribution column head cabinet; and providing a power supply and a connecting line of the newly-added power distribution column head cabinet, a connecting line of the newly-added power distribution column head cabinet and the computing equipment, and the like. Such changes may require various system and component configurations to be re-added, removed, etc., and may involve changes to the floor space, wall space, etc. of the data center 100; even reconfiguration of various systems and components in the data center 100 may require that certain systems and components be temporarily taken off-line, i.e., computing units may also need to be shut down to effect changes in particular systems and components, thereby exacerbating retrofit costs.

The embodiment of the application provides a power supply module, which is in an n +1 power supply configuration form and can support 2n branch power supply input. Therefore, under the condition that the configuration of the existing data center is not supported, for example, the number of the interfaces of the power supply and the power distribution column head cabinet is not enough, and the machine room is required to be modified, 2n branch power supply input can be adopted, the interfaces of the power supply and the power distribution column head cabinet are saved, and the machine room modification is avoided.

The power module can be applied to any electronic device which needs to be powered, and in the embodiment of the application, the electronic device can be specifically a computer device or a storage device, a wireless device, a network device, and the like. The server 201 is taken as an example below. In the example of fig. 2 described above, server 201 has 12 input connectors, requiring 6 power supply interfaces plugged into power distribution column head cabinet 211 and power distribution column head cabinet 212, respectively. However, the first power distribution column cabinet 211 and the first power distribution column cabinet 212 respectively have only 7 power supply interfaces, and after the server 202 and the server 203 are connected, only 5 power supply interfaces are left for the server 201 to connect, which is not enough to support normal access of the server 201. Based on the power module provided by the embodiment of the application, the server 201 only needs to be connected with 10 power supply interfaces, and the power module can reliably supply power for the server 201.

Referring to the schematic structural diagram of the power module shown in fig. 5, the power module includes (n + 1) power modules, where there are 2 single-input power modules and (n-1) dual-input power modules in the (n + 1) power modules. The single input power module includes an input connector and a power source. The power supply is a device which converts alternating current into stable direct current through a power transformer and provides electric energy for a load; the input connector is used for connecting the power supply module and an external power supply so that the power supply module receives power supply input of the external power supply.

The dual-input power supply module comprises two input connectors, a power supply and two-way change-over switches, wherein each power supply comprises two ports, one port is connected with the corresponding two-way change-over switch, and the other port is connected with a load and used for supplying power to the load. The single-input power supply module comprises an input connector and a power supply, wherein one port of the power supply is connected with the input connector, and the other port of the power supply is connected with a load and used for supplying power to the load. The load may be any device, electronic component, etc. that needs to be powered, such as a computing device, e.g., a server, a switching device, e.g., a switch, a router, and an electronic component, e.g., a processor, a chip, etc. Wherein the content of the first and second substances,

the input of the two-way change-over switch is two-way, and specifically can be an A-way input and a B-way input. The A path input and the B path input are respectively connected to the two-way change-over switch through input connectors. The double-circuit change-over switch can automatically switch input into the other one when any one of the double-circuit input is in power failure, so that the load is prevented from being influenced by power failure.

In some embodiments, the two-way switch may set one of the inputs, for example, the a-input, as a default power supply, and the power supply may generally supply power to the load based on the default power supply, and when the default power supply is powered down, the two-way switch immediately switches the input to the B-input. Optionally, when the default power supply, such as the a-way input, resumes power, the two-way switch may also switch the input back to the default power supply.

Specifically, break before make (sts) switching can be integrated in the structure of the two-way change-over switch, ac can also be rectified into dc and then combined, only any one of the two ways a and B is electrified, and the power supply can work normally.

As shown in fig. 6, the left diagram in fig. 6 is an sts static transfer switch, which can realize uninterrupted switching between different power supplies. The ac/dc is a power converter with alternating current as input and direct current as output; the ac/dc converter rectifies a high-frequency ac voltage by using a secondary-side rectifier diode, smoothes the high-frequency ac voltage by using a capacitor, and converts the high-frequency ac voltage into a set dc output voltage. In some embodiments, in a normal operating state, the default power supply supplies power to the load when the default power supply is within a normal voltage range. When the default power supply fails, the standby power supply is automatically switched to, and after the default power supply is recovered to be normal, the default power supply is automatically switched to.

In the right diagram of fig. 6, dc/dc is a power converter with dc input and dc output; the dc/dc converter can change the electric energy of one voltage value into the electric energy of another voltage value in a direct current circuit. The two-way change-over switch receives two-way input, input electric energy respectively passes through the ac/dc converter, after the ac is rectified into dc, the two-way dc electric energy is combined through the dc/dc converter, and one-way electric energy with a preset voltage value is output. When one of the power supplies fails, the output of the two-way change-over switch is not affected.

In some embodiments, the power module 303 may be integrated, and specifically, the two-way switch may be integrated into the power supply, on one hand, the assembly operation may be reduced, the assembly efficiency may be improved, on the other hand, the size of the power module may be reduced, the space may be saved, and the protection of the two-way switch may be realized by integrating the two-way switch inside the power supply.

In some embodiments, the two-way switch may not be provided in the power module, but rather within the server 201.

In some embodiments, the input connector and the power supply may be independent of each other, the power supply and the input connector may be connected via a PCB board and/or a backplane, and the connection may include a cable or a copper bar.

In some embodiments, the power module may be integrated, as shown in fig. 7, and fig. 7 illustrates an exemplary power module including 4 single-input power modules, and it can be seen that in fig. 7, the power and input connectors of each of the 4 power modules are fixedly connected in a housing, i.e., the power and input connectors are non-detachably connected. The power module provided in the embodiment of the present application can also be integrated, and includes 2 single-input power modules and (n-1) dual-input power modules, and can support 2n branch power supply inputs.

By way of specific example, fig. 8 shows a power module configured in a power configuration 5+1, where n is 5. Fig. 8 includes 6 power modules and 10 input connectors, where the 6 power modules include 4 dual-input power modules and 2 single-input power modules, where every two input connectors of the 8 input connectors (input connector 1 to input connector 8) are connected to one dual-input power module, and the 2 input connectors (input connector 11 and input connector 12) are respectively connected to one single-input power module. Each dual-input power supply module receives two paths of power supply inputs (an A path input and a B path input) by connecting two input connectors, and each single-input power supply module receives one path of power supply input by connecting one input connector. Wherein, the

input connectors

1, 3, 5 and 7 are respectively connected with one input port of 4 double-input

power supply modules

1, 2, 3 and 4; the

input connectors

2, 4, 6 and 8 are respectively connected with the other input ports of the 4 dual-input

power supply modules

1, 2, 3 and 4; the single input power supply module 5 receives the input of the A path through the connection input connector 9; the single input power module 6 receives the B-path input through the connection input connector 10.

In this connection,

input connectors

1, 3, 5, 7, 9 are connected to the a-line input, and

input connectors

2, 4, 6, 8, 10 are connected to the B-line input; in this case, if the server power is 15kw, each power module is 3kw, the data center provides a input 5 branches a and a input 5 branches B, respectively, and a total of 10 branches of input corresponds to each power module, where the a and B branches are independent from each other.

It can be seen that the single-input power module 5 and the single-input power module 6 receive only 1-way input, and in fig. 8, the single-input power module 5 receives a-way input, and the single-input power module 6 receives a B-way input. Under normal power supply conditions, 6 power modules can provide 3kw × 6=18kw power supply capability. And at the moment, the 6 power supply modules are only connected with 10 branches, so that two interfaces of the power distribution column head cabinet are saved.

In the case of abnormal power supply, for example, if the input of the path a is powered down, 5 power modules (

power modules

1, 2, 3, 4 and 6) of the input of the path B can also provide the power supply capacity of 3kw × 5= 11 kw; for example, if the input of the B path is powered down, 5 power modules (

power modules

1, 2, 3, 4, and 5) of the input of the a path can also provide a power supply capability of 3kw × 5= 15kw; for another example, if 1 power source fails, the remaining 5 power sources have a power supply capacity of 3kw × 5= 15kw. Under the condition that 1 of the paths a or b is powered off or 1 of the paths a or b is in fault, the service is not influenced, and the power supply reliability is ensured.

It can be understood that the connection manner of the power supply module and the input connector can be various, and the embodiment of the present application does not limit this.

Here, taking the connection manner of the n +1 power modules (n is 5) and the input connector in the server 201 described in the above fig. 9 as an example, the connection manner of the external power distribution column head cabinet and the server 201 is shown below. As shown in fig. 10, the server 201 includes 10 input connectors (the 1 st input connector to the 10 th input connector in order from left to right correspond to the input connector 1 to the input connector 10 in fig. 10).

Generally, for a server 201 having a (5+1) power configuration, 12 input connectors are required to receive two-way power inputs, each providing 6 branches, i.e., a total of 12 power interfaces are required. It can be seen that, in the case where the server 202 and the server 203 both access the power supply normally, the power distribution head cabinet 211 and the power distribution head cabinet 212 each have 5 power supply interfaces left, which are not enough to support the normal access of the server 201. In contrast, the embodiment of the present application designs a power module, which is configured as a (5+1) power supply, but has only 10 input connectors, and the power module is mounted on the server 201, and the connection manner of the power module and the input connectors is as shown in fig. 9, and only the 10 input connectors need to be connected with a power supply, so that normal power supply and reliable power supply can still be achieved.

According to the power supply module provided by the embodiment of the application, the power supply configuration mode of the power supply module is n +1 configuration, and the power supply module comprises (n-1) double-input power supply modules and 2 single-input power supply modules. The (n + 1) power supply modules need to be provided with 2n input connectors, wherein each dual-input power supply module in the (n-1) dual-input power supply modules is provided with 2 input connectors, and each single-input power supply module in the 2 single-input power supply modules is provided with 1 input connector. Under the condition of receiving 10 branches of power supply inputs, (n + 1) power supply modules can still realize normal power supply and reliable power supply for the server 201. I.e., the n +1 configuration of power modules may support a 2n branch power input.

In some embodiments, the plurality of input connectors may be presented with sequence numbers indicating sequential user interfacing with the power supply. For example, a sequence number of each input connector is identified on a cabinet of the server 201, if the sequence number starts from 1, the input connector with the number 1 is the input connector 1 in the embodiment of the present application, the input connector with the number 2 is the input connector 2 in the embodiment of the present application, and so on; if the sequence label starts from 0, the input connector labeled 0 is the input connector 1 in the embodiment of the present application, the input connector labeled 1 is the input connector 2 in the embodiment of the present application, and so on; if the sequence starts with a, the input connector with a is the input connector 1 in the embodiment of the present application, the input connector with b is the input connector 2 in the embodiment of the present application, and so on.

The above describes the power supply configuration of n +1, and the connection and power supply situation in the scenario where n is 5. For any value of n, the connection method of the embodiment of the present application can be adopted.

As shown in fig. 10, fig. 10 includes (n + 1) power modules and 2n input connectors, and the input connectors are used for connecting the power supply and the power modules. The (n + 1) power supply modules comprise (n-1) double-input power supply modules and 2 single-input power supply modules, each double-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 respectively connected with an input connector; each single-input power supply module is connected with one input connector; wherein n is an integer greater than 1. When the 2n input connectors are connected with the power supply input of the power supply, the (n + 1) power supply modules in the power supply module realize power supply.

In one possible embodiment, each dual-input power module receives two power inputs of a power supply, a first single-input power module of the 2 single-input power modules receives one of the two power inputs, and a second single-input power module of the 2 single-input power modules receives the other of the two power inputs.

In one possible implementation, the 2 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 sequentially connected with the 1 st input connector to the (2 n-2) th input connector; the first single-input power supply module is connected with the (2 n-1) th input connector; the second single input power supply module is connected with the 2 nth input connector. According to the common interface habit in the industry, the input connectors are connected in sequence, so that the last two input connectors are used as the input connectors for connecting the two single-input power supply modules. Under the condition that a power supply path connected with the last input connector fails, n power supply modules in the power supply module realize power supply, and under the condition that two power supply paths connected with the last two input connectors fail, only (n-1) power supply modules in the power supply module realize power supply. The most possible connection mode is provided, the interface habit of a user is fully adapted, and the universality of practical application is realized.

As shown in fig. 10, when the 2n input connectors are connected to the power supply input, the (n + 1) power modules in the power module supply power. If one path of power supply input connected with the odd-numbered input connectors fails, the other path of power supply input connected with the even-numbered input connectors supplies power to the n power supply modules connected with the even-numbered input connectors; if one power supply module of the (n + 1) power supply modules fails, the remaining n power supply modules provide power.

It can be seen that the input connector (2 n-1) is connected to the single input power supply module n, the input connector 2n is connected to the single input power supply module (n + 1); in fig. 10, the power supply module n receives the input of the a path, and the power supply module (n + 1) receives the input of the B path. Under the condition that the power supply is normally supplied by the power supply source, (n + 1) power supply modules can provide power supply capacity. In the abnormal condition of power supply, for example, if the input of the A path is powered down, the n power supply modules (the dual-input

power supply modules

1, 2, …, n-1 and the single-input power supply module n + 1) of the input of the B path can also provide power supply capacity; for example, if the B-path input is powered down, n power supply modules (the dual-input

power supply module

1, 2, 3, n-1 and the single-input power supply module n) of the A-path input can also provide power supply capacity; also for example, if 1 power supply fails, the remaining n power supplies have power supply capability. Under the condition that 1 of the paths A or B is in power failure or 1 of the paths B is in fault, the service is not influenced, and the power supply reliability is ensured.
