Description

Technical Field

[0001] The present application belongs to the field of power management technology, and in particular relates to a power supply system, method, device, product, and computer storage medium. Background Art

[0002] At present, an uninterruptible power supply (UPS) power supply system is a power supply system with an energy storage device. It can be used to provide uninterruptible power supply to equipment and scenarios with high requirements for power supply stability (such as data centers), thereby ensuring the safe and stable operation of the equipment.

[0003] To ensure safe, reliable, and robust power supply, most current uninterruptible power supply (UPS) systems utilize a dual-redundancy architecture (2N). This architecture allows for shared power and load sharing across two UPS systems, effectively ensuring safe and stable equipment operation. However, these systems utilize different mains electricity sources during circuit connection. Consequently, if one mains source experiences an anomaly and disconnects, all UPS units in the system will switch to batteries for power.

[0004] If the battery fails, the power supply on that power line will cease, and the entire equipment load will be carried by the other power line. This will prevent the equipment from maintaining dual power supply at all times, resulting in the risk of equipment downtime. This can also have serious negative consequences in critical scenarios. For example, if a single power line is used, the data security of data center equipment cannot be fully guaranteed, increasing the probability of operational risks. Therefore, ensuring that the two uninterruptible power supply systems maintain dual power supply at all times is a critical issue that needs to be addressed. Summary of the Invention

[0005] The embodiments of the present application provide a power supply system, method, device, product, and computer storage medium to ensure that the target device always maintains dual power supply, thereby providing strong security protection for the operation of the device.

[0006] In a first aspect, an embodiment of the present application provides a power supply system, including:

[0007] The power supply system includes a first uninterruptible power supply system and a second uninterruptible power supply system. The first uninterruptible power supply system and the second uninterruptible power supply system each include a plurality of uninterruptible power supply hosts connected in parallel. Each uninterruptible power supply host includes a main circuit and a bypass circuit. Each main circuit is configured with a battery. The battery is used to supply power to the load when the configured main circuit stops supplying main power.

[0008] Input ends of main circuits of multiple uninterruptible power supply hosts in the first uninterruptible power supply system are connected to different mains supplies;

[0009] Input ends of main circuits of multiple uninterruptible power supply hosts in the second uninterruptible power supply system are connected to different mains supplies;

[0010] Output terminals of the first uninterruptible power supply system and the second uninterruptible power supply system are connected to the target device to jointly supply power to the target device.

[0011] In a second aspect, an embodiment of the present application provides a power supply method, including:

[0012] The mains input of the first uninterruptible power supply system and the second uninterruptible power supply system in the power supply system is monitored by a control circuit preset in the power supply system, where the mains power is the first mains power or the second mains power;

[0013] When the first mains or the second mains input is disconnected, the input end of the target main circuit is connected to the configured battery through the control circuit. The target main circuit is the main circuit of the uninterruptible power supply host whose main input mains is disconnected.

[0014] The target device is powered by the battery of the uninterruptible power supply host whose main input power is disconnected, and the main circuit whose input power is not disconnected.

[0015] When it is monitored that the first mains power or the second mains power is disconnected and all batteries in the power supply system have power failures, the target device is powered by the main circuit through which the mains power is not disconnected.

[0016] In a third aspect, an embodiment of the present application provides a terminal device, the device comprising: a processor and a memory storing computer program instructions;

[0017] When the processor executes the computer program instructions, the power supply method of the second aspect is implemented.

[0018] In a fourth aspect, an embodiment of the present application provides a computer storage medium, on which computer program instructions are stored. When the computer program instructions are executed by a processor, the power supply method of the second aspect is implemented.

[0019] In a fifth aspect, an embodiment of the present application provides a computer program product. When the instructions in the computer program product are executed by a processor of an electronic device, the electronic device executes the power supply method as in the second aspect.

[0020] The technical solutions provided by the embodiments of this application bring at least the following beneficial effects:

[0021] Embodiments of the present application provide a power supply system, method, device, product, and computer storage medium. The system includes a first uninterruptible power supply system and a second uninterruptible power supply system. Multiple uninterruptible power supply hosts within the first and second uninterruptible power supply systems each receive a main circuit input from a different mains supply, while bypass circuits within the system receive the same mains supply. The first and second uninterruptible power supply systems jointly provide power to a target device.

[0022] The system and corresponding technical solutions provided by the embodiments of this application can effectively ensure that in a dual-power supply scenario, when one of the mains power inputs stops and the battery power supply fails, the target device can still maintain dual-power input. This effectively reduces the risk of power outages and downtime for the target device, maintains a safe and stable power supply process, and provides strong protection for the normal operation and data security of the target device.

[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0030] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0031] Currently, uninterruptible power supply (UPS) systems are crucial for ensuring continuous power supply in devices and scenarios requiring high power stability, such as data centers. To enhance the reliability and robustness of the power supply process, UPS systems typically employ a dual-redundancy architecture. This architecture involves two independent UPS systems operating in parallel, each connected to a different mains input to share the power load required by the device, thereby ensuring safe and stable operation.

[0032] However, while this power supply method effectively improves the reliability and safety of the power supply system, potential problems still exist in actual operation. Because each UPS system is typically connected to a different mains input, if one mains input is disconnected, that UPS system will use the battery in the main circuit to power the equipment. The other UPS system with an active mains input will continue to provide mains power.

[0033] In this case, if the battery is damaged or a power failure occurs, the UPS system, disconnected from the mains input, will no longer be able to power the equipment. Consequently, the equipment, which was originally powered by two mains circuits, will be powered by a single mains circuit, with the entire load being supplied by the single UPS system. This single-circuit power supply poses a significant risk to the normal operation of the equipment, increasing the probability of downtime and interruption, and failing to fully guarantee the operation of the equipment and data security.

[0034] Based on the above technical problems, embodiments of the present application provide a power supply system, method, device, product, and computer storage medium. The power supply system includes: a first uninterruptible power supply system and a second uninterruptible power supply system, each of which includes multiple uninterruptible power supply hosts connected in parallel, each of which includes a main circuit and a bypass circuit, and the main circuit is configured with a battery for supplying power to the load when the main mains power is disconnected. The main circuits of the multiple uninterruptible power supply hosts in the first uninterruptible power supply system and the second uninterruptible power supply system are input with different mains power supplies, while the bypass circuits within the systems are input with the same mains power supply. The first uninterruptible power supply system and the second uninterruptible power supply system jointly provide power for the target device.

[0035] In addition, an embodiment of the present application also provides a power supply method applied to the above-mentioned power supply system. Specifically, it includes: flexibly switching the power supply mode according to the actual situation through the control circuit. When monitoring a certain mains power disconnection input, the control circuit switches the input end of the main circuit of the first uninterruptible power supply system and the second uninterruptible power supply system whose main input mains power is disconnected to a connection with a configured battery. Then, the target device can be powered by the battery of the uninterruptible power supply host whose main input mains power is disconnected, and the main circuit of the uninterruptible power supply host whose main input mains power is not disconnected.

[0036] When it is monitored that a certain mains power input is disconnected and all batteries in the power supply system fail to supply power, the target device can be powered by the main circuits of the uninterruptible power supply hosts whose main input mains power is not disconnected in the first uninterruptible power supply system and the second uninterruptible power supply system.

[0037] Based on the above, it can be seen that the power supply system and corresponding technical solutions provided by the embodiments of the present application can effectively ensure that in a dual-power supply scenario, when one of the mains power inputs stops and the battery power supply has problems, the target device still maintains stable dual-input power supply. The continuous and stable dual-power supply process can effectively reduce the risk of power outages and shutdowns of the target device, maintaining the safety and stability of the overall power supply process while also providing strong protection for the normal operation and data security of the target device.

[0038] It should be noted that the embodiments provided in this application do not strictly limit the specific application scenarios of the above-mentioned power supply systems, methods, devices, products and computer storage media, and can be flexibly applied according to actual needs.

[0039] For example, in the actual scenario of dual-powering hardware equipment in a data center, by applying the power supply system and corresponding power supply method provided by the embodiments of the present application, when a single mains power input is disconnected and all batteries experience a power failure, it is possible to effectively prevent all uninterruptible power supply hosts in a single uninterruptible power supply system from losing power. The power supply method for the electrical equipment in the data center will not be reduced to a single-power supply due to power supply problems, and stable and continuous dual-power supply can be successfully maintained.

[0040] The power supply system and method provided in the embodiments of the present application can effectively improve the safety and robustness of the power supply process for electrical equipment in a data center. No special power supply conditions or abnormalities will cause the electrical equipment to be in a dangerous situation of single-circuit power supply. While ensuring the power safety of electrical equipment, it also provides strong protection for the normal operation and data security of the data center.

[0041] It should be noted that the application scenarios described in the above embodiments of the present application are intended to more clearly illustrate the power supply system and power supply method provided in the embodiments of the present application, and do not constitute a limitation on the power supply system and power supply method provided in the embodiments of the present application. Those skilled in the art will appreciate that, with the emergence of new application scenarios, the power supply system and power supply method provided in the embodiments of the present application are also applicable to similar technical problems. The power supply system, method, device, product, and computer storage medium provided in the embodiments of the present application can be applied to various application scenarios requiring dual-circuit power supply to electrical equipment.

[0042] The power supply system provided in the embodiment of the present application can be specifically referred to Figure 1 As shown in .

[0043] Figure 1 A schematic diagram of the structure of a power supply system provided in an embodiment of the present application. Reference numeral 101 represents a first uninterruptible power supply system, reference numeral 102 represents a second uninterruptible power supply system, reference 103 represents an input terminal of the uninterruptible power supply system, reference 104 represents an uninterruptible power supply host portion of the uninterruptible power supply system, reference 105 represents an output terminal of the uninterruptible power supply system, and reference 106 represents a target device.

[0044] like Figure 1 As shown in FIG, the power supply system provided by the embodiment of the present application includes a first uninterruptible power supply system 101 and a second uninterruptible power supply system 102. Figure 1 As can be seen, the uninterruptible power supply host part 104 of the first uninterruptible power supply system 101 and the second uninterruptible power supply system 102 respectively includes multiple uninterruptible power supply hosts connected in parallel, namely Figure 1It should be noted that the embodiment of the present application does not specifically limit the number (N) of uninterruptible power supply hosts included in the first uninterruptible power supply system, and is at least two or more, and can be flexibly adjusted according to application scenarios and actual needs.

[0045] Figure 1 The internal circuit structure of each uninterruptible power supply host can be referred to Figure 2 As shown in .

[0046] Figure 2 This is a schematic diagram of the structure of an uninterruptible power supply (UPS) provided in an embodiment of the present application. Reference numeral 201 represents the rectifier in the main circuit, reference numeral 202 represents the inverter in the main circuit, reference numeral 203 represents the battery configured for the main circuit, and reference numeral 204 represents the static switch in the bypass circuit.

[0047] like Figure 2 As shown in Figure 1 For each uninterruptible power supply host, the uninterruptible power supply host contains Figure 2 The main circuit and bypass circuit are shown in .

[0048] The main circuit includes a rectifier 201, an inverter 202, and a pre-configured battery 203. Rectifier 201 converts AC mains power into DC power for subsequent input to inverter 202 or to charge the battery. Inverter 202 converts DC power from rectifier 201 or the battery into AC power for output to the target device. Battery 203 is specifically used to power the load (i.e., the target device) when the main circuit is disconnected from the mains power supply.

[0049] The bypass circuit can be divided into two connections, one of which is the main bypass circuit, which is equipped with a static switch 204. The static switch 204 can be specifically composed of Figure 2 The two reverse-parallel thyristors shown in FIG2 can promptly switch to a bypass circuit to power the target device in the event of a failure in inverter 202 in the main circuit. The other bypass circuit is a manual bypass circuit, which has no device and only a manual switch. This can be used for planned maintenance of the uninterruptible power supply or to manually switch from main power to bypass power in an emergency.

[0050] Figure 2 The whole is shown in Figure 1 The internal circuit structure of each uninterruptible power supply host. Figure 1As shown in the figure, the AC power is divided into a first AC power and a second AC power. In the power supply system provided in the embodiment of the present application, the input ends of the main circuits of the multiple uninterruptible power supply hosts 1-1 to 1-N in the first uninterruptible power supply system 101 are respectively connected to different AC power supplies, and the input ends of all bypass circuits are connected to the same AC power supply, which is the first AC power.

[0051] The input ends of the main circuits of the plurality of UPS hosts 2-1 to 2-N in the second UPS system 102 are also connected to different mains power supplies, and the input ends of all bypass circuits are connected to the same mains power supply, namely the second mains power supply.

[0052] The mains power connected to the input end of the main circuit of the target uninterruptible power supply host in the first uninterruptible power supply system 101 can be the same as the mains power connected to the input end of the bypass circuit in the first uninterruptible power supply system 101, that is, Figure 1 The input end of the main circuit of the uninterruptible power supply host 1-1 (the target uninterruptible power supply host) shown in FIG is the first mains power supply that is the same as the input end of the bypass circuit. The main circuit input ends of the other uninterruptible power supply hosts in the first uninterruptible power supply system 101, except for the target uninterruptible power supply host, can be connected to a mains power supply that is different from the mains power supply connected to the input end of the bypass circuit, that is, Figure 1 The input end of the main circuit of the uninterruptible power supply host 1-2 to 1-N shown in the figure is the second mains power.

[0053] Similarly, the mains power connected to the input end of the main circuit of the target uninterruptible power supply host in the second uninterruptible power supply system 102 can be the same as the mains power connected to the input end of the bypass circuit in the second uninterruptible power supply system 102, that is, Figure 1 The input terminal of the main circuit of the uninterruptible power supply host 2-1 (the target uninterruptible power supply host) shown in FIG is the second mains power supply that is the same as the input terminal of the bypass circuit. The main circuit input terminals of the other uninterruptible power supply hosts in the second uninterruptible power supply system 102, except for the target uninterruptible power supply host, can be connected to a mains power supply that is different from the mains power supply connected to the input terminal of the bypass circuit, that is, Figure 1 The input end of the main circuit of the uninterruptible power supply host 2-2 to 2-N shown in the figure is the first AC power.

[0054] It should be noted that the embodiment of the present application does not strictly limit the number of target uninterruptible power supply hosts in each uninterruptible power supply system. Figure 1 The one UPS host shown in the figure is the target UPS host, and other quantities may be used, as long as it is ensured that in each UPS system, there is at least one UPS host whose main circuit input end is connected to a different AC power supply from that of other UPS hosts. It can be flexibly adjusted according to the application scenario and actual needs.

[0055] Furthermore, if Figure 1 By connecting the circuit in the circuit, the output ends of the two uninterruptible power supply systems can be connected to the target device at the same time, thereby realizing dual power supply to the target device.

[0056] When one of the mains power lines (the first mains power line or the second mains power line) is disconnected for some special reason, the uninterruptible power supply host with the disconnected mains power line in the single uninterruptible power supply system can switch to battery power supply, while the uninterruptible power supply host with the mains power line still connected can continue to be powered by the mains power line. In this case, the two uninterruptible power supply systems in the embodiment of the present application can always maintain dual power supply to the target device, thereby ensuring the safety and reliability of the power supply process and providing strong protection for the stable operation and data security of the target device.

[0057] In addition, when a certain mains input is disconnected and multiple or all batteries in the entire power supply system fail to supply power, the mains input mains is disconnected and the uninterruptible power supply host with no normal battery supply will not be able to supply power through the main circuit. Figure 1 The power supply system provided by the embodiment of the present application shown in the figure can ensure that in this case, there is an uninterruptible power supply host with the main input AC power not disconnected in each uninterruptible power supply system. At this time, according to the load condition of each uninterruptible power supply host, power can be supplied to the target device through the uninterruptible power supply host with the main input AC power not disconnected or bypass power supply.

[0058] Therefore, when a single mains power line is disconnected and a battery power failure occurs, the power supply system provided by the embodiment of the present application can also provide dual power supply to the target device, significantly improving the safety and stability of the power supply process. The successful implementation of maintaining dual power supply to the target device under any abnormal circumstances provides a strong guarantee for the stable operation of the target device and the security of its data.

[0059] In order to better understand the workflow of the power supply system of the embodiment of the present application and the power supply mode under different circumstances, the embodiment of the present application also provides a power supply method that can be applied to the above power supply system. The specific operation and processing flow of the power supply method can be referred to Figure 3 shown.

[0060] Figure 3 A flowchart of a power supply method provided in an embodiment of the present application includes steps S301 to S304.

[0061] S301: Monitoring the mains input of a first uninterruptible power supply system and a second uninterruptible power supply system in the power supply system through a control circuit preset in the power supply system.

[0062] In step S301, the power supply method provided by the embodiment of the present application can be Figure 1 The control circuit preset in the power supply system shown in the figure performs real-time mains input monitoring on the first uninterruptible power supply system and the second uninterruptible power supply system in the power supply system.

[0063] Among them, the control circuit can be specifically understood as a circuit for detecting the input, output and working conditions of each circuit and device in the power supply system. The control circuit can specifically include but is not limited to: an input detection circuit for detecting the mains input, a rectifier control circuit for monitoring the working condition of the rectifier in the main circuit, a battery management circuit for monitoring the working status of the battery, an inverter control circuit for monitoring the working condition of the inverter in the main circuit, a static switch control circuit responsible for switching the main power supply and the bypass power supply, etc. The specific connection conditions and architecture of the control circuit are not strictly limited in the embodiments of this application, and can be flexibly limited according to the application scenario and actual needs.

[0064] S302: When it is monitored that the first mains power or the second mains power is disconnected from the input, the input end of the target main circuit is connected to the configured battery through the control circuit.

[0065] In step S302, when the control circuit detects that one of the mains (the first or second mains) connecting the two uninterruptible power supply systems has been disconnected, the control circuit can be used to set the main circuit of the uninterruptible power supply host whose main input mains power is disconnected, either in the first or second uninterruptible power supply system, as the target main circuit. The input end of the target main circuit can be switched to a battery configured to correspond to the target main circuit, thereby outputting direct current (DC) power to an inverter. The inverter then converts the DC power into AC power and outputs it to the target device.

[0066] For ease of understanding, the above Figure 1 The power supply system shown in FIG. 1 is used as an example. Assume that the first AC power supply connected to the bypass circuit input of the first uninterruptible power supply system 101 is disconnected, and the main AC power input of the uninterruptible power supply 1-1 is disconnected. In this case, the control circuit can switch the main circuit input of the uninterruptible power supply 1-1 to the corresponding battery, and the battery will be used to provide power output to the uninterruptible power supply 1-1.

[0067] Similarly, the disconnection of the first mains power supply also disconnects the mains power supply of the UPS units 2-2 through 2-N in the first UPS system 102. This allows the control circuit to switch the main circuit inputs of the UPS units 2-2 through 2-N to the corresponding batteries. In this case, dual power supply is maintained for the target device, ensuring power supply security while also effectively safeguarding the target device's operation and data security.

[0068] S303: The target device is powered by the battery of the uninterruptible power supply host whose main input mains power is disconnected and the main circuit whose main input mains power is not disconnected.

[0069] In step S303, based on the connection adjustment achieved by the control circuit in S302, for example Figure 1 The power supply system shown can, when one of the mains inputs is disconnected, supply power to the target device through the batteries in the first and second UPS systems, which have lost their main input, and the main circuit of the UPS system that has not lost its main input. This ensures that the target device always has dual power supply, improving the safety and stability of the power supply process and providing strong security for the target device's operation and data security.

[0070] S304: When it is monitored that the first mains power or the second mains power is disconnected and all batteries in the power supply system have power failures, the target device is powered by a main circuit that has not been disconnected from the mains power.

[0071] In step S304, when the control circuit detects that the first AC power or the second AC power input is disconnected, if all batteries in the power supply system have power failures or all uninterruptible power supply hosts whose main input AC power is disconnected have failed, the power supply method provided in the embodiment of the present application can jointly power the target device through the main circuits of the remaining uninterruptible power supply hosts whose main input AC power is not disconnected in the first uninterruptible power supply system and the second uninterruptible power supply system.

[0072] In this special case, based on Figure 1 The power supply system shown in the figure can effectively prevent a single uninterruptible power supply system from completely stopping supplying power due to mains disconnection or battery failure, ensuring that dual power supply can be maintained for the target equipment at all times, improving the safety and stability of the power supply process, and providing strong protection for the safety and stability of the target equipment's operation process.

[0073] For ease of understanding, we still use the above Figure 1 The power supply system shown is used as an example for illustration. Assume that the mains power is disconnected and that the batteries in the UPS 1-1 in the first UPS system 101 and the UPSs 2-2 to 2-N in the second UPS system 102, or all batteries in the power supply system, fail, resulting in a power outage.

[0074] In this case, since the input ends of the main circuits of the uninterruptible power supply hosts 1-2 to 1-N in the first uninterruptible power supply system 101 and the uninterruptible power supply host 2-1 in the second uninterruptible power supply system 102 are connected to the second AC power supply, the target device can be powered by the main circuits of these uninterruptible power supply hosts whose main input AC power is not disconnected, thereby successfully achieving dual-circuit power supply to the target device.

[0075] In addition, considering that a single uninterruptible power supply host may not be able to directly bear the load of the entire uninterruptible power supply system, in an embodiment provided in the present application, when the control circuit monitors that the first mains power or the second mains power input is disconnected, and at this time all batteries in the power supply system have power supply failures or all uninterruptible power supply hosts with the main input mains disconnected have failed, the power supply method provided in the embodiment of the present application can determine the actual load corresponding to each uninterruptible power supply system and the total rated load of the uninterruptible power supply hosts in each uninterruptible power supply system whose main input mains power is not disconnected through the above-mentioned control circuit.

[0076] The actual load is used to indicate the amount of power that the UPS system needs to provide to the target device during the power supply process, while the rated load of the UPS host is used to indicate the maximum amount of power that the UPS host can provide.

[0077] Next, for each UPS system, if the actual load corresponding to that UPS system is determined to be no greater than the total rated load of the remaining UPS units in the system that have not yet been disconnected from the mains input, it can be determined that the remaining UPS units in the system that have not yet been disconnected from the mains input can fully bear the load of the entire UPS system. In this case, the target device can be directly powered through the main circuit of the remaining UPS units in the system that have not yet been disconnected from the mains input.

[0078] When it is determined that the actual load corresponding to the uninterruptible power supply system is greater than the total rated load of the uninterruptible power supply hosts whose main input mains power is not disconnected in the uninterruptible power supply system, it means that the remaining uninterruptible power supply hosts whose main input mains power is not disconnected in the uninterruptible power supply system are unable to fully bear the load of the entire uninterruptible power supply system. If the main circuit of the uninterruptible power supply host whose main input mains power is not disconnected in the uninterruptible power supply system is still selected to power the target device, it will cause one or more uninterruptible power supply hosts to operate in an overloaded manner, thereby increasing the operational risk of the power supply process. In severe cases, it may even cause the entire power supply system to be paralyzed.

[0079] Based on the above issues, in this case, when it is determined that the bypass input mains power in the uninterruptible power supply system is not disconnected, the power supply method provided in the embodiment of the present application can change the power supply connection between all uninterruptible power supply hosts in the uninterruptible power supply system and the target device to a bypass connection through the control circuit. Then, the target device can be powered by the bypass circuits of all uninterruptible power supply hosts in the uninterruptible power supply system.

[0080] Through the above-mentioned load comparison and main bypass switching process, it is possible to flexibly select the power supply mode according to the load, greatly reducing the potential risks of the power supply process, maintaining the continuous safety and stability of the entire power supply process, and providing strong protection for the normal operation of the target equipment and the security of equipment data.

[0081] For ease of understanding, we still use the above Figure 1 . Similarly, assume that the first mains power input is disconnected, and at this time, the batteries in the uninterruptible power supply host 1-1 in the first uninterruptible power supply system 101 and the uninterruptible power supply hosts 2-2 to 2-N in the second uninterruptible power supply system 102, or all the batteries in the power supply system, fail, resulting in a failure in power supply.

[0082] For the second UPS system 102, the main input power to UPS units 2-2 through 2-N is disconnected, leaving only the main input power to UPS unit 2-1 still connected to the secondary mains. If the actual load of the second UPS system 102 is 100 watts, and the rated load of UPS unit 2-1 is 40 watts, then the main input power to UPS unit 2-1 alone cannot safely support the entire load of the second UPS system 102.

[0083] In this case, the technical solution provided by the embodiment of the present application can switch all uninterruptible power supply hosts 2-1 to 2-N in the second uninterruptible power supply system 102 from main power supply to bypass power supply through the control circuit, thereby effectively sharing the load, avoiding overload operation, and ensuring the normal power supply of the second uninterruptible power supply system 102. This effectively improves the safety and stability of the entire power supply process and provides strong protection for the normal operation of the target equipment and data security.

[0084] In addition to the above, the power supply system and power supply method provided in the embodiments of the present application can also cope with scenarios where the mains input is disconnected due to a fault other than the mains power itself. For example, when a high-voltage distribution, multi-level distribution, transformer or other processing process or device in the mains input power supply system fails, the power supply system and power supply method provided in the embodiments of the present application are still applicable, and can ensure that the target device is always powered on in any scenario where a single mains power input stops.

[0085] The above is the specific structural composition of the power supply system provided in the embodiment of the present application, as well as the specific implementation method of the power supply method. The main circuits of the multiple uninterruptible power supply hosts in the first uninterruptible power supply system and the second uninterruptible power supply system in the power supply system are input with different mains electricity, and the bypass circuits inside the system are input with the same mains electricity, so that under any circumstances, the first uninterruptible power supply system and the second uninterruptible power supply system can jointly provide power for the target device. The power supply system and the corresponding power supply method provided in the embodiment of the present application can effectively ensure that in the dual-power supply scenario, when one of the mains electricity stops inputting and the battery power supply has problems, the target device can still maintain dual-input power supply. It effectively reduces the risk of power outages and shutdowns of the target device, maintains the safety and stability of the power supply process, and also provides strong protection for the normal operation and data security of the target device.
