Description

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 25, 2023, with application number 202311247314.7 and application name “A power supply method, power supply system and cabinet”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the field of computers, and in particular to a power supply method, a power supply system and a cabinet. Background Art

[0003] With the development of artificial intelligence, big data and other businesses, the computing power and power supply requirements of data centers have also increased. Taking the regional intelligent computing center as an example, based on the demand for P-level / E-level computing power, thousands of processors (such as xPU chips) need to be combined into a computing power cluster that can be uniformly scheduled through a high-speed network. Due to the large number of processors, tens of megawatts (MW) of mains power are usually required.

[0004] At present, when a transient power supply event occurs in a cabinet, more power needs to be provided to the cabinet instantly. For example, when the equipment in the cabinet is working at an overclocked frequency or the mains power is cut off, more power needs to be provided to the equipment in the cabinet to meet the normal operation of the equipment. However, the mains power capacity is usually configured according to the rated power of the cabinet, which cannot meet the transient power supply requirements of the equipment in the cabinet when working at an overclocked frequency. In addition, the power supply for the cabinet cannot meet the transient power supply requirements of the cabinet when the mains power is cut off. Therefore, how to provide a solution to the problem of low power supply reliability of the cabinet when a transient power supply event occurs in the cabinet has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The present application provides a power supply method, a power supply system and a cabinet, thereby improving the power supply reliability of the cabinet when a transient power supply event occurs in the cabinet.

[0006] In a first aspect, a power supply method is provided, and the method is applied to a power supply system, the power supply system includes a power supply unit (PSU) and a burst power supply module, the PSU is used to provide power supply capacity that meets the steady-state power supply demand of the cabinet, and the burst power supply module is used to provide power supply capacity that meets the transient power supply demand of the cabinet, the PSU and the burst power supply module are both connected to the bus of the cabinet, and the method includes: detecting the status of the cabinet where the power supply system is located; when the status shows that a transient power supply event occurs in the cabinet, triggering the PSU and the burst power supply module to coordinate power supply to the cabinet according to the transient power supply demand.

[0007] In this way, a burst power supply module is added to the power supply system in the cabinet. When the PSU supplies power to the cabinet at a constant power, the burst power supply module connected to the busbar can obtain the power storage energy. When a transient power supply event occurs in the cabinet, the burst power supply module quickly replenishes the power required by the cabinet and supplies power to the cabinet to meet the transient power supply needs of the cabinet. Thus, the power supply reliability of the cabinet is improved when a transient power supply event occurs in the cabinet.

[0008] Compared with configuring the AC power capacity based on the peak power of the cabinet (such as overclocking peak power), the equipment in the cabinet works in a non-continuous overclocked state, resulting in a generally low power utilization rate. The solution provided by this application can configure the AC power capacity according to the rated power of the cabinet, reduce the quota of the AC power capacity, and when a transient power supply event occurs in the cabinet, the PSU and the burst power supply module cooperate to supply power to the cabinet to improve the power utilization rate. Under the condition of the same AC power capacity, the solution provided by this application can deploy more computing units (such as XPU for data processing) in the cabinet, improve the computing power of the cabinet, and realize business value-added.

[0009] In a possible implementation, the burst power supply module includes an energy storage unit, which includes a plurality of passive components, wherein the energy storage unit uses the plurality of passive components to store electrical energy, for example, the passive components include aluminum capacitors, high voltage capacitors, super capacitors, and the like.

[0010] Compared with using lithium batteries in the cabinet as energy storage media to achieve peak-shaving and valley-filling, lithium batteries have potential safety hazards. Since passive components can work when there is a signal without power supply, such as when voltage is applied to both ends of a capacitor, the capacitor stores charge, which effectively eliminates the potential safety hazards of energy storage media in the cabinet. In addition, compared with lithium batteries, the storage capacity of capacitors is larger, so that the burst power supply module containing passive components can provide power supply capabilities of hundreds of milliseconds or seconds when the mains power is lost, improving the power supply reliability of the cabinet when the mains power is lost.

[0011] In another possible implementation, multiple passive components included in the energy storage unit are connected in parallel to achieve fault isolation between the parallel passive components and ensure the reliability of the energy storage unit.

[0012] In another possible implementation, the method further includes: the PSU supplies power to the cabinet at a constant power, and multiple passive components in the burst power supply module store electrical energy.

[0013] Therefore, when the PSU is able to provide steady-state power supply to the cabinet, multiple passive components in the burst power supply module are used to store electrical energy, so that when a transient power supply event occurs in the cabinet, the burst power supply module can quickly supplement the electrical energy required by the cabinet and power the cabinet to meet the transient power supply needs of the cabinet.

[0014] In another possible implementation, the method further includes: when a transient power supply event occurs in the cabinet, the burst power supply module supplies power to the cabinet by discharging multiple passive components in the burst power supply module.

[0015] Therefore, when a transient power supply event occurs in the cabinet, the burst power supply module quickly supplements the power required by the cabinet, supplies power to the cabinet, and meets the transient power supply demand of the cabinet.

[0016] In another possible implementation, the PSU and the burst power supply module are triggered to coordinate power supply to the cabinet according to transient power supply demand, including: the burst power supply module detects that the bus voltage is less than or equal to the bus voltage threshold, and the burst power supply module adjusts the operating frequency of the burst power supply module to cooperate with the PSU to power the cabinet.

[0017] Thus, the burst power supply module can discharge smoothly, cooperate with the PSU to supply power to the cabinet, and provide a stable voltage to the cabinet.

[0018] In another possible implementation, the PSU and the burst power supply module are triggered to coordinate power supply to the cabinet according to the transient power demand, including: coordinating the PSU and the burst power supply module to power the cabinet according to the number of devices in the cabinet that require transient power supply.

[0019] Therefore, the PSU and burst power supply module can be reasonably coordinated to supply power to the cabinet according to the transient power supply demand, saving energy.

[0020] In another possible implementation, the PSU and the burst power supply module are triggered to coordinate power supply to the cabinet according to the transient power supply demand, including: the PSU detects that the transient power supply event is that the equipment in the cabinet is operating at overclocking, and the PSU and the burst power supply module jointly power the cabinet.

[0021] Since the power required by the cabinet will increase instantly when the equipment in the cabinet is working at overclocking, the burst power supply module and PSU together supply power to the cabinet, which can meet the transient power supply needs of the cabinet, realize power supply for the high peak-to-average ratio load in the cabinet, meet the power supply needs of the burst power supply module for hundreds of milliseconds, and achieve peak shaving.

[0022] In another possible implementation, the PSU and the burst power supply module are triggered to coordinate power supply to the cabinet according to the transient power supply demand, including: the PSU detects that the transient power supply event is a mains power failure, and the burst power supply module supplies power to the cabinet.

[0023] When the mains power goes out, the PSU loses its power source and cannot continue to supply power to the cabinet for a long time, and cannot meet the cabinet's transient power supply needs. In this case, the PSU can be placed in a no-load state, for example, by lowering the PSU's output voltage so that the PSU does not supply power to the cabinet, and the burst power supply module supplies power to the cabinet, thereby improving the cabinet's ability to resist mains power outages. Since the burst power supply module uses passive components to store electrical energy, the cabinet can resist mains power outages of hundreds of milliseconds or seconds, thereby improving the cabinet's ability to resist long-term mains power outages.

[0024] For example, the PSU lowers the output voltage of the PSU, and the PSU and the burst power supply module cooperate to supply power to the cabinet. When the equipment in the cabinet works at overclocking, the output voltage of the PSU can be equal to the output voltage of the burst power supply module, and the PSU and the burst power supply module jointly supply power to the cabinet. When the mains power fails, the output voltage of the PSU can be less than the output voltage of the burst power supply module, and the burst power supply module supplies power to the cabinet.

[0025] In another possible implementation, the power supply system includes a plurality of burst power supply modules, and the plurality of burst power supply modules are disposed in at least one unit space in the cabinet.

[0026] The size of the burst power supply module is designed according to the unit space of the cabinet, so that the burst power supply module can be flexibly arranged in at least one unit space in the cabinet, thereby improving the adaptability of the burst power supply module.

[0027] In another possible implementation, the PSU and the burst power supply module coordinate to supply power to the cabinet, including: multiple burst power supply modules supply power to the components in the cabinet based on parallel current sharing.

[0028] In this way, by connecting multiple burst power supply modules in parallel, fault isolation between the parallel burst power supply modules is achieved to ensure the reliability of the energy storage unit. When a transient power supply event occurs in the cabinet, multiple parallel burst power supply modules can quickly supplement the power required by the cabinet and power the cabinet to meet the transient power supply needs of the cabinet.

[0029] In another possible implementation, the method also includes: the PSU obtains an overclocking working signal of a device in the cabinet, triggering the PSU and the burst power supply module to coordinate powering the cabinet; or, the burst power supply module obtains a mains power-off signal, triggering the burst power supply module to power the cabinet.

[0030] In this way, the PSU or burst power supply module can be notified of the transient power supply event in the cabinet as soon as possible, quickly replenish the power required by the cabinet, and supply power to the cabinet to meet the transient power supply needs of the cabinet.

[0031] In another possible implementation, the method further includes: the PSU detects that the transient power supply event ends, the PSU supplies power to the cabinet at a constant power, and multiple passive components in the burst power supply module store electrical energy.

[0032] In a second aspect, a power supply system is provided, the power supply system comprising a PSU and a burst power supply module, the power supply system being used to execute the operation steps of the method in the first aspect or any possible implementation manner of the first aspect.

[0033] In a possible implementation, the burst power supply module includes an energy storage unit, which includes a plurality of passive components; wherein the energy storage unit uses the plurality of passive components to store electrical energy.

[0034] In another possible implementation, the power supply system includes a plurality of burst power supply modules, and the plurality of burst power supply modules are disposed in at least one unit space in the cabinet.

[0035] In a third aspect, a cabinet is provided, comprising a power supply system as described in the second aspect or any possible implementation of the second aspect, the power supply system being used to execute the operating steps of the method in the first aspect or any possible implementation of the first aspect.

[0039] The technical effects brought about by any design method in the second to sixth aspects can refer to the technical effects brought about by the first aspect or different design methods in the first aspect, and will not be repeated here.

[0040] Based on the implementations provided in the above aspects, the present application can also be further combined to provide more implementations. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] To facilitate understanding, the main terms involved in this application are first explained.

[0058] Power Supply Unit (PSU): A power supply mounted on a printed circuit board. Power supply modules are used to provide power to various devices in a computer system. Devices include, but are not limited to, application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads.

[0059] Overclocking: It is a technology that increases the main frequency (i.e., clock pulse frequency) of a device, thereby increasing the operating frequency of the device. For example, increasing the operating frequency of the processor in a computer system (such as main frequency, external frequency, and frequency multiplier). Processors include central processing units (CPU), graphics processing units (GPU), data processing units (DPU), neural processing units (NPU), and embedded neural-network processing units (NPU), which are high-power computing units with computing capabilities. When a device is overclocked, the device needs to consume more power, and the power module needs to provide greater power supply capacity.

[0060] Power: A physical quantity used to indicate the work done by an object in a unit of time, that is, power represents the speed of an object doing work. The unit of power is watt (W), abbreviated as W. Power can be represented by P, P = W / t, W represents work, the unit of work is joule, t represents unit time, and the unit of t is second (S).

[0061] Rated power of a power module: It indicates the power of a power module under stable and continuous operation, and indicates the power supply capacity of the power module under stable and continuous operation. For example, the rated power of a power module is the rated voltage of the power module multiplied by the rated current, that is, P = W / t = UI, where U represents the rated voltage and I represents the rated current.

[0062] Output power of the power module: used to indicate the power provided by the power module when supplying power to the load. The output power of the power module is the output voltage of the power module multiplied by the output current. If the output power is greater than the rated power, the power module will activate the over power protection (OPP) function and then shut down the power supply. If the over power protection is not activated, the power module will be damaged by overheating. Over power protection refers to the mechanism that the output power of the power module continues to rise and reaches the threshold, and the power module automatically cuts off the power to avoid overcurrent damage to the power module.

[0063] Burst power is used to indicate the instantaneous power provided to meet the transient power supply requirements of the device (such as overclocking).

[0064] Voltage: It can also be called potential difference or electric potential difference. It is a physical quantity that measures the energy difference generated by the unit charge in the electrostatic field due to the different electric potential. The input voltage of the power module refers to the voltage supplied by the outside world or applied to the power module. The output voltage of the power module refers to the voltage supplied by the power module to the outside world or applied to the outside world.

[0065] Mains electricity: refers to alternating current (AC), using the common characteristics of AC: voltage, current, and frequency. Common AC frequencies are 50 Hz and 60 Hz. Civilian AC voltage ranges from 100V to 380V. For example, the mains with an AC voltage of 380V and an AC frequency of 50HZ is used as the power supply for the computer room.

[0066] Thermal Design Power (TDP): It is an indicator of the heat release of a device, which can refer to the heat generated per unit time when the device is working. Thermal design power consumption can also be called heat dissipation design power consumption.

[0067] Electronic Design Power (EDP): It is the power consumption indicator of the device during transient power supply.

[0068] Transient: refers to the instantaneous changes of current and voltage in a circuit within a short period of time.

[0069] In order to solve the problem of low power supply reliability of the cabinet when a transient power supply event occurs in the cabinet, the present application provides a power supply method, which can also be called a power supply enhancement (Power Turbo) method. A burst power supply module is added to the power supply system including the PSU, and the PSU is used to provide a power supply capability that meets the steady-state power supply requirements of the cabinet. The burst power supply module is used to provide a power supply capability that meets the transient power supply requirements of the cabinet. Both the PSU and the burst power supply module are connected to the bus of the cabinet. When it is detected that the status of the cabinet where the power supply system is located shows that a transient power supply event has occurred in the cabinet, the PSU and the burst power supply module are triggered according to the transient power supply demand to coordinate the power supply to the cabinet. Among them, the burst power supply module can also be called an instantaneous power supply module or an instantaneous power supply module.

[0070] Since a burst power supply module is added to the power supply system in the cabinet, when the PSU supplies power to the cabinet at a constant power, the burst power supply module connected to the busbar can obtain the power storage energy. When a transient power supply event occurs in the cabinet, the burst power supply module quickly replenishes the power required by the cabinet and supplies power to the cabinet to meet the transient power supply needs of the cabinet. Thus, the power supply reliability of the cabinet is improved when a transient power supply event occurs in the cabinet.

[0071] Compared with configuring the AC power capacity based on the peak power of the cabinet (such as overclocking peak power), the equipment in the cabinet works in a non-continuous overclocked state, resulting in a generally low power utilization rate. The solution provided by this application can configure the AC power capacity according to the rated power of the cabinet, reduce the quota of the AC power capacity, and when a transient power supply event occurs in the cabinet, the PSU and the burst power supply module cooperate to supply power to the cabinet to improve the power utilization rate. Under the condition of the same AC power capacity, the solution provided by this application can deploy more computing units (such as XPU for data processing) in the cabinet, improve the computing power of the cabinet, and realize business value-added.

[0072] The method provided in the present application can be applied to scenarios such as large supercomputers, regional supercomputers, and public clouds. For example, a high performance computing (HPC) scenario. The burst power supply module can be set in a cabinet or outside a cabinet in the above scenario. The present application does not limit the form of the cabinet in which the burst power supply module is added. For example, the burst power supply module is set inside a cabinet server, a blade server, or a rack server. For another example, the burst power supply module is set outside a supercomputing cabinet server.

[0073] The power supply method provided by the present application is described in detail below with reference to the accompanying drawings. Figure 1 This is a schematic diagram of a cabinet system provided in this application. Figure 1 As shown, the cabinet system 100 includes a power supply module 110, a burst power supply module 120 and an electronic device 130. The electronic device 130 may include a plurality of devices 131.

[0074] The device 131 includes electronic components used for data processing or communication in a computer system, such as a processor, a memory and a memory (also referred to as a main memory unit), a network adapter (such as a network interface card (NIC), an intelligent network interface card (iNIC)), etc. The processor may be a central processing unit (CPU), a graphics processing unit (GPU), a data processing unit (DPU), a neural processing unit (NPU), an embedded neural network processor (NPU), etc., such as an XPU used for data processing.

[0075] It is worth mentioning that Figure 1 The rack system 100 may include one or more devices, wherein the types of the multiple devices may be the same or different. For example, the rack system 100 may include multiple types of XPUs such as CPU, GPU, NPU, etc. The processor may be a multi-core (multi-CPU) processor.

[0076] The power supply module 110 and the burst power supply module 120 can serve as a power supply system to supply power to the device 131 in the electronic device 130 .

[0077] The power module 110 is used to supply power to the electronic device 130 in the cabinet system 100 at a constant power. For example, the power module 110 is used to supply power to the electronic device 130 in the cabinet system 100 at a rated power for a long time. For example, the rated power may be 3 kilowatts (kW).

[0078] The electronic device 130 may include a voltage dividing module, and the voltage dividing module is used to convert the input voltage of the electronic device 130 into a voltage required by the device 131 in the electronic device 130 .

[0079] When the power module 110 supplies power to the electronic device 130 in the cabinet system 100 at a constant power, the burst power supply module 120 stores electrical energy.

[0080] The burst power supply module 120 is used to cooperate with the power supply module 110 to supply power to the cabinet system 100 when a transient power supply event occurs in the cabinet system 100 .

[0081] In some embodiments, the power module 110 and the burst power module 120 are respectively connected to the busbar, so that the burst power module 120 cooperates with the power module 110 to supply power to the cabinet system 100 .

[0082] For servers of different types, the bus voltage may be different. For example, Figure 2 As shown in (a) in FIG. 1 , the bus voltage may be 48V, and the input voltage of the cabinet system 100 may be 380V AC. Figure 2 As shown in (b), the bus voltage may be 12V, and the input voltage of the cabinet system 100 may be 220V AC.

[0083] In other embodiments, the burst power supply module 120 is disposed outside the cabinet system 100, the power supply module 110 is disposed inside the cabinet system 100, and the power supply module 110 and the burst power supply module 120 are respectively connected to the busbar. Figure 2 As shown in (c), the bus voltage may be 48V, the input voltage of the computer room may be 380V AC, and the 380V AC is converted into 400V DC through high-voltage direct current (HVDC) transmission to provide 400V DC for the cabinet system 100.

[0084] Figure 1 In the example, only a cabinet system 100 including one power module 110 and one burst power module 120 is taken. Here, one power module 110 and one burst power module 120 are respectively used to indicate a type of equipment. In a specific embodiment, the number of each type of equipment can be determined according to demand.

[0085] For example, Figure 3 As shown in (a), in a cabinet, a burst power supply module is deployed in a space of 1U or several U. One or more burst power supply modules can also be deployed in 1U. At least one burst power supply module can be set in a cabinet. It is worth noting that the burst power supply module is an energy storage device. The more burst power supply modules are set in a single cabinet, the stronger its ability to provide transient power supply to the devices in the cabinet. For example, 4 burst power supply modules can be deployed in 1U, which can support the transient power supply needs of 10 servers in a single cabinet.

[0086] In some embodiments, the ratio of burst power supply modules to power supply modules can be configured according to the transient power supply requirements of the cabinet. For example, the number of power supply modules and the number of burst power supply modules are designed according to the thermal design power consumption and circuit design power consumption of the components in the cabinet. Thus, burst power supply modules and power supply modules are configured as needed, power supply resources are saved, the power supply and distribution costs of the computer room are reduced, and the scalability of the power supply system in the cabinet is improved.

[0087] For example, Figure 3As shown in (b), in Examples 1 to 3, the thermal design power consumption is greater than the circuit design power consumption, which means that the components in the cabinet dissipate more heat when working at the rated frequency, and dissipate less heat when working at overclocking. In this case, more power modules can be configured, and fewer burst power modules can be configured. In Example 4, the thermal design power consumption is equal to the circuit design power consumption, so the same number of power modules and burst power modules can be configured.

[0088] In other embodiments, the size of the burst power supply module is the same as that of the PSU, and the interface format of the burst power supply module is designed according to the interface format of the PSU, thereby improving the adaptability of the burst power supply module and realizing flexible mixing of the burst power supply modules in the cabinet.

[0089] For example, Figure 4 As shown, the interface format of the PSU includes a positive power interface, a negative power interface, a signal interface, a ground interface, a live interface, and a neutral interface. The output interface of the PSU includes a positive power interface and a negative power interface. The input interface of the PSU includes a ground interface, a live interface, and a neutral interface. The interface format of the burst power supply module includes a positive power interface, a negative power interface, and a signal interface. The output interface of the burst power supply module includes a positive power interface and a negative power interface.

[0090] Figure 5 This is a schematic diagram of the structure of a burst power supply module provided in this application. Figure 5 As shown, the burst power supply module 500 includes an energy storage unit 510 and a voltage stabilizing unit 520. The energy storage unit 510 includes passive components such as aluminum capacitors, high-voltage capacitors, and supercapacitors. The energy storage unit 510 is used to store electrical energy. The voltage stabilizing unit 520 is used to control the charging and discharging voltage of the burst power supply module 500 to ensure the life and safety of the burst power supply module 500. For example, the functions of the voltage stabilizing unit 520 include voltage stabilization function, overload protection function, and short circuit protection function.

[0091] When charging the burst power supply module 500 , the voltage stabilizing unit 520 can increase the input voltage so that the energy storage unit 510 stores electrical energy; when discharging the burst power supply module 500 , the voltage stabilizing unit 520 can lower the output voltage and supply power to the device through the bus 530 .

[0092] The charging and discharging management of the energy storage unit can be achieved through an isolated or non-isolated bidirectional DC-to-DC converter (DC-DC), or a power topology with separate charging and discharging circuits can be used, such as using a boost circuit to charge the energy storage unit and a buck circuit to discharge the energy storage unit. The charging and discharging management of the energy storage unit can be designed to any bus voltage based on actual needs and device selection. Figure 6A schematic diagram of the circuit structure of an explosive power supply module provided in the present application. Q1, Q2, Q3 and Q4 in the circuit can be switches (such as transistors), and the switches are turned on or off to realize the charging and discharging of the energy storage unit. Capacitor C1 is connected to the bus, and C2 serves as an energy storage medium. For example, when charging the energy storage unit 510, Q1 and Q4 are first turned on to charge the inductor, Q1 and Q4 are turned off, Q2 and Q3 are turned on, and C2 is charged; when the energy storage unit 510 is discharged, Q2 and Q3 are first turned on, C2 is discharged, Q2 and Q3 are turned off, Q1 and Q4 are turned on, the inductor is discharged, and the electric energy is transmitted to the bus through C1.

[0093] The voltage stabilizing unit 520 may further include a microcontroller unit (MCU) for regulating the rapid charging or discharging of the burst power supply module 500. For example, the MCU controls the on or off of Q1, Q2, Q3, and Q4 to regulate the rapid charging or discharging of the energy storage unit 510.

[0094] In other embodiments, the energy storage unit may include multiple passive components, which are connected in parallel to achieve fault isolation between passive components and ensure the reliability of the energy storage unit. Physical protection measures such as glue-filled capacitors may also be added to ensure the safety of energy storage unit applications. Figure 7 A schematic diagram of the circuit structure of an energy storage unit provided in this application, wherein multiple capacitors are connected in parallel in multiple stages, and resistors, fuses and diodes are also arranged between the capacitors and the busbars to ensure the safety and availability of the energy storage unit.

[0095] Next, a power supply method provided by the present application is described in conjunction with the accompanying drawings. Figure 8 Here we use Figure 1 The power supply module 110 and the burst power supply module 120 shown in the cabinet system 100 are used as an example to illustrate power supply to the cabinet.

[0096] Step 810: The PSU supplies power to the components in the cabinet at a constant power, and the burst power supply module stores electrical energy.

[0097] Since both the PSU and the burst power supply module are connected to the bus, the output voltage of the PSU can be higher than the output voltage of the burst power supply module. In this case, the PSU supplies power to the cabinet at a constant power through the bus, the burst power supply module stores electric energy, and the burst power supply module does not supply power to the cabinet.

[0098] Step 820: The PSU detects the status of the cabinet where the power supply system is located.

[0099] The MCU in the PSU can collect the power supply parameters of the PSU, such as the input voltage, output voltage, input current, and output current. The MCU determines whether a transient power supply event occurs in the cabinet based on the collected power supply parameters. For example, if the MCU determines that the output power of the PSU is greater than the power threshold, the devices in the cabinet may be working at an overclocking frequency, and an overclocking event occurs in the cabinet. For another example, if the MCU determines that the output current of the PSU is greater than the current threshold, the devices in the cabinet may be working at an overclocking frequency, and an overclocking event occurs in the cabinet. An overclocking event may refer to a device operating at a higher operating frequency (for example, a power exceeding the rated power) to improve processing performance. Subsequently, in order to meet the overclocking function of the device, more electrical energy needs to be provided to the device, and the cabinet power supply demand increases instantly.

[0100] For another example, if the MCU determines that the input voltage of the PSU is less than the voltage threshold, a mains power outage may occur, and a mains power outage event may occur in the cabinet. A mains power outage event may refer to a sudden interruption of the mains power, in which case the bus voltage may decrease, and the device may not work properly. Therefore, the device also needs to be provided with power to enable the device to work properly when the mains power is lost.

[0101] Step 830: When the PSU detects a transient power supply event in the cabinet, the PSU and the burst power supply module are triggered to coordinate power supply to the cabinet according to the transient power supply demand.

[0102] After a transient power supply event occurs in the cabinet, the PSU can lower the output voltage of the PSU according to the transient power supply demand, so that the output voltage of the PSU is less than or equal to the output voltage of the burst power supply module, so that the burst power supply module cooperates with the PSU to power the cabinet.

[0103] After an overclocking event occurs in the cabinet, the PSU can lower the output voltage of the PSU according to the transient power supply demand. For example, the PSU adjusts the first output voltage to the second output voltage, and the second output voltage of the PSU is equal to the output voltage of the burst power supply module, that is, the output voltage of the PSU is adjusted to the same voltage as the output voltage of the burst power supply module, so that the PSU and the burst power supply module jointly power the cabinet to meet the power required by the device when the device is overclocked.

[0104] After a power outage occurs in the cabinet, the PSU can lower the output voltage of the PSU according to the transient power supply demand. For example, the PSU adjusts the first output voltage to the second output voltage, and the second output voltage of the PSU is less than the output voltage of the burst power supply module. Since the output voltage of the PSU is lower than the output voltage of the burst power supply module, the burst power supply module supplies power to the cabinet to meet the power required by the devices when the mains power is lost.

[0105] Since the PSU does not need to supply power to the cabinet, the MCU in the PSU can continue to monitor the cabinet and detect whether the transient power supply event of the cabinet has ended. The burst power supply module then supplies power to the cabinet, which can meet the cabinet's transient power supply requirements of hundreds of milliseconds or seconds, and improve the cabinet's power supply reliability when the mains power is off. For example, the MCU in the PSU collects the PSU's input voltage, output voltage, input current, output current and other power supply parameters, and determines whether the cabinet's transient power supply event has ended based on the power supply parameters. The PSU detects that the PSU's output current can be 0, indicating that the PSU is in a no-load state and the PSU does not need to supply power to the cabinet.

[0106] It should be noted that the PSU may include a microcontroller unit (MCU), which lowers the output voltage of the PSU according to transient power supply events, so that the burst power supply module cooperates with the PSU to supply power to the devices in the cabinet to meet transient power supply requirements.

[0107] In other embodiments, the burst power supply module may include multiple passive components such as high-voltage capacitors and super capacitors, and multiple passive components are connected in parallel. The PSU supplies power to the devices in the cabinet at a constant power through the bus, and multiple parallel passive components store electrical energy. After a transient power supply event occurs in the cabinet, the burst power supply module cooperates with the PSU to supply power to the devices in the cabinet based on the electrical energy stored in the multiple parallel passive components in the burst power supply module.

[0108] For example, multiple burst power supply modules connected in parallel can be used in conjunction with the PSU to supply power to devices in a cabinet based on parallel current sharing.

[0109] For example, a burst power supply module can provide power for a 250-A load. When the device in the cabinet is overclocked, the current is 1000 A. Four burst power supply modules can be configured in the cabinet. When the device in the cabinet is overclocked, the four burst power supply modules jointly power the device.

[0110] As another example, a burst power supply module can discharge for 20 milliseconds, and multiple burst power supply modules can be configured in the cabinet. For example, 5 burst power supply modules are configured in the cabinet. The discharge of 5 burst power supply modules can meet the power supply need of 100 milliseconds, thereby meeting the long-term power supply demand when the city power is lost.

[0111] In some embodiments, the PSU may determine the number of burst power modules that assist the PSU in supplying power to the cabinet according to the number of overclocked devices in the cabinet.

[0112] In other embodiments, multiple levels of power thresholds may be preset, and the PSU determines a burst power supply module for powering the cabinet based on the output power of the PSU and the multiple levels of power thresholds.

[0113] Optionally, since both the PSU and the burst power supply module are connected to the bus, after the PSU lowers the output voltage of the PSU, the burst power supply module detects that the bus voltage is less than the bus threshold, and the burst power supply module adjusts the operating frequency or duty cycle, such as increasing the operating frequency or duty cycle, so that the burst power supply module discharges smoothly and cooperates with the PSU to supply power to the cabinet. Optionally, the burst power supply module may also include an MCU, and the MCU adjusts the operating frequency or duty cycle.

[0114] Step 840: The PSU detects that the transient power supply event is over, and the PSU supplies power to the components in the cabinet at a constant power, and the burst power supply module stores electrical energy.

[0115] The MCU in the PSU can collect the power supply parameters of the PSU, such as the input voltage, output voltage, input current, and output current. The MCU determines the end of the transient power supply event of the cabinet based on the collected power supply parameters. For example, if the MCU determines that the output power of the PSU is less than the power threshold, the device in the cabinet may end with overclocking, and the MCU determines that the overclocking event of the cabinet has ended. For another example, if the MCU determines that the output current of the PSU is less than the current threshold, the device in the cabinet may end with overclocking, and the MCU determines that the transient power supply event of the cabinet has ended.

[0116] For another example, if the MCU determines that the input voltage of the PSU is greater than a voltage threshold, the AC power may be restored, and the MCU determines that the AC power failure event is over.

[0117] After the cabinet transient power supply event ends, the PSU increases the output voltage of the PSU so that the output voltage of the PSU is greater than the output voltage of the burst power supply module, so that the PSU supplies power to the devices in the cabinet at a constant power, the burst power supply module continues to charge, and the burst power supply module stores electrical energy.

[0118] The power supply method provided in the present application is to install a burst power supply module inside the cabinet. When the PSU supplies power to the devices in the cabinet at a constant power, the burst power supply module containing passive components stores electric energy. After a transient power supply event occurs in the cabinet, the burst power supply module cooperates with the PSU to supply power to the devices in the cabinet. This method can meet the transient power supply requirements of the high peak-to-average ratio load of the devices in the cabinet of the order of hundreds of milliseconds or seconds, and cut the peak of the transient power supply demand of the cabinet. The AC power capacity is configured according to the rated power of the cabinet, the quota of the AC power capacity is reduced, and the utilization rate of the AC power is improved. Under the condition of the same AC power capacity, more devices can be deployed in the cabinet to improve the computing power of the cabinet and realize value-added services.

[0119] For example, the peak elimination effect of the traditional solution and the peak elimination effect of the solution of the present application are compared with the accompanying drawings. Fig. 9 As shown in (a) in the figure, the AC capacity is configured according to the peak power of the cabinet in the traditional solution. The bus voltage remains unchanged. When the device is overclocked, the current increases. In order to meet the power demand of the device, the AC current increases. Fig. 9 As shown in (b), when the AC power capacity is configured according to the rated power of the cabinet, the current increases when the device is overclocked. In order to meet the power demand of the device, the burst power supply module cooperates with the PSU to power the device. Therefore, the AC power only needs to provide the TDP power supply demand of the cabinet, and the burst power supply module provides the EDP power supply demand of the cabinet at the microsecond / millisecond / hundred millisecond / second level. The burst power supply module replenishes the power supply of the device, thereby improving the power supply reliability of the cabinet when a transient power supply event occurs.

[0120] The following takes the overclocking scenario as an example. Figure 8 The power supply method in the transient power supply scenario shown in FIG. Fig.10 As shown, the device is overclocked (step 1010), the PSU detects the output power of the PSU in real time (step 1020), and the PSU determines whether the output power of the PSU exceeds the PSU power threshold (step 1030). If the output power of the PSU does not exceed the PSU power threshold, continue to detect the output power of the PSU, that is, continue to execute step 1020; if the output power of the PSU exceeds the PSU power threshold, it means that the storage device in the cabinet is overclocked, the load suddenly increases, and the PSU lowers the output voltage of the PSU (step 1040). Optionally, the burst power supply module detects the bus voltage in real time (step 1050), and the burst power supply module determines whether the bus voltage is lower than the bus threshold (step 1060). If the bus voltage is not lower than the bus threshold, continue to detect the bus voltage, that is, continue to execute step 1050. If the bus voltage is lower than the bus threshold, the burst power supply module adjusts the operating frequency or duty cycle, such as increasing the operating frequency or duty cycle, so that the burst power supply module discharges smoothly and cooperates with the PSU to supply power to the devices in the cabinet. That is, the burst power supply module and the PSU jointly supply power to the device (step 1070) to achieve turbo peak elimination.

[0121] Fig.11 Schematic diagram of the bus voltage & joint load control strategy example provided in this application. Among them, t0~t1: the mains power is normal, and the PSU is normally loaded; t1: 100 milliseconds overclocking; the PSU slow loop constant power reduces the output voltage, for example, the output voltage of the PSU is reduced from 54.5V to 52V; t1~t2: the PSU and the burst power module fast loop are jointly loaded, and the burst power module releases electrical energy at a high rate to quickly replenish the peak-cutting energy; t2: the 100 millisecond cycle ends, and the PSU increases the output voltage of the PSU; t2~t3: the PSU supplies power to the device, and replenishes energy to the burst power module at a low rate.

[0122] Therefore, through the bus voltage control in the cabinet, combined with the PSU slow-loop constant power algorithm and the burst power supply module fast-loop voltage regulation algorithm, the common bus joint loading can be achieved to meet the load power supply accuracy requirements and improve the utilization rate of the mains power.

[0123] The following takes the mains power outage scenario as an example. Figure 8 The power supply method in the transient power supply scenario shown in FIG. Fig.12 As shown, the AC power is cut off (step 1210), the PSU detects the input voltage of the PSU in real time (step 1220), and the PSU determines whether the input voltage of the PSU triggers the power-off threshold (step 1230). If the input voltage of the PSU does not trigger the power-off threshold, continue to detect the input voltage of the PSU, that is, continue to execute step 1220; if the input voltage of the PSU triggers the power-off threshold, it means that the AC power may be cut off, and the PSU lowers the output voltage of the PSU (step 1240). The PSU detects the input voltage of the PSU in real time (step 1250), and the burst power supply module supplies power to the cabinet (step 1260); the PSU determines whether the AC power is restored (step 1270). If the AC power is not restored, continue to execute step 1260. If the AC power is restored, the PSU increases the output voltage of the PSU, and the PSU supplies power to the cabinet (step 1280).

[0124] based on Fig.12 The method shown, Fig.13 Schematic diagram of the bus voltage control strategy example provided in this application. Among them, t0~t1: the mains power is normal, the PSU is loaded; t1: the mains power is interrupted, and the PSU quickly reduces the output voltage after 4 milliseconds, for example, the output voltage of the PSU is reduced from 54.5V to 51V, and the burst power supply module is loaded; t1~t2: the burst power supply module is loaded (the output capacity can be maintained for S seconds at this time); the PSU is in a no-load working state; t2: the interruption is restored, the mains power is normal, the PSU re-adjusts the output voltage, re-loads, and recharges the burst power supply module.

[0125] Therefore, by controlling the bus voltage inside the cabinet, during the mains power outage stage, the output voltage of the PSU is lowered to achieve PSU unloading, and the burst power supply module is used for power supply, thereby improving the ability to resist input mains power outages from 10 milliseconds to hundreds of milliseconds.

[0126] For Class C data center computer rooms, since Class C data center computer rooms have no strong power supply requirements, the computer room does not need to be equipped with UPS. The city power can be directly supplied to the computer room to power the cabinets, greatly reducing the power supply and distribution costs of the computer room.

[0127] In other embodiments, a signal linkage can be established between the burst power supply module, PSU and the device. Combined with the business advance prediction, the PSU and the burst power supply module can execute the power supply method provided by this application according to the linkage signal, further optimize the implementation effect, and improve the utilization rate of the mains power. For example, Fig.14As shown, when the device is overclocked, an overclocking signal can be sent to the PSU and the burst power supply module, so that the PSU reduces the output power of the PSU, and the burst power supply module adjusts the operating frequency or duty cycle, such as increasing the operating frequency or duty cycle, so that the burst power supply module discharges smoothly and cooperates with the PSU to supply power to the devices in the cabinet. When the mains power fails, the PSU can send a power-off signal to the burst power supply module, so that the burst power supply module adjusts the operating frequency or duty cycle, and the burst power supply module discharges smoothly and cooperates with the PSU to supply power to the devices in the cabinet.

[0128] As a possible implementation, Fig.15 A schematic diagram of a power supply system provided for this application is shown in FIG. Fig.15 As shown, the power supply system 1500 includes a cabinet-level power conversion module 1510, a burst power supply module 1520, a board-level power conversion module 1530 and an artificial intelligence processor 1540. The cabinet-level power conversion module 1510, the burst power supply module 1520, the board-level power conversion module 1530 and the artificial intelligence processor 1540 are connected through a power bus 1550. Among them, the cabinet-level power conversion module 1510 is connected to the main power supply, and the number of each device can be one or more. When multiple cabinet-level power conversion modules are set, multiple cabinet-level power conversion modules can form a global pool for converting the voltage provided by the main power supply into the voltage required by each server or device. The burst power supply module is used to provide the system with a burst power supply voltage so as to provide the required voltage for the artificial intelligence processor to meet the demand. The burst power supply module technology can maximize the envelope performance and improve the utilization rate of the mains. On the one hand, it can provide the best envelope performance. When the power supply appears within hundreds of milliseconds, the AI ​​computing power can be significantly improved in a short time, and the integral effect of heat dissipation can maximize the envelope performance. On the other hand, the burst power supply module can better provide the utilization rate of the mains power, ensure the safe and stable power supply of the whole cabinet, prevent excessive mains power, and greatly improve the utilization rate of the mains power.
