[0021] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0022] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.
[0023] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0024] According to one aspect of an embodiment of the present application, a power supply control method is provided. Optionally, in an embodiment of the present application, the power supply control method can be applied to, but is not limited to, Figure 1 In the hardware environment shown, including the power supply device 102 and the electronic device 104, the electronic device 104 includes a power supply unit 1042 and a power load 1044. The power supply device 102 can provide a power supply voltage to the power supply unit 1042, and the power supply unit 1042 is used to convert the output voltage of the power supply device 102 into an input voltage for the power load 1044.
[0025] The power supply device 102 may be, but is not limited to, a power supply cabinet, a switch cabinet, or a transformer. The electronic device 104 may be, but is not limited to, a server, a switch, or other types of equipment. The power load 1044 may be a central processing unit (CPU), memory, hard drive, network card, fan, or other electrical components within the electronic device 104, or other electrical components.
[0026] The power supply control method of the embodiment of the present application can be executed by the control component inside the electronic device 104, or can be executed jointly by the control component inside the electronic device 104 and the power supply device 102, wherein the control component inside the electronic device 104 is part of the power supply unit 1042, or can be set independently of the power supply unit 1042.
[0027] Taking the power supply control method of this embodiment executed by the control component inside the electronic device 104 as an example, Figure 2 FIG. 1 is a flow chart of an optional power supply control method according to an embodiment of the present application, such as Figure 2 As shown, the process of the method may include steps S202 to S208.
[0028] Step S202 : continuously acquiring load power data of a power supply unit of the electronic device from a mainboard control component of the electronic device, wherein the load power data is used to represent a change trend of the load power of the electrical load on the electronic device.
[0029] Step S204: dynamically adjust the parameter value of the first control parameter of the primary side circuit of the power supply unit according to the acquired load power data, wherein the change trend of the parameter value of the first control parameter is consistent with the change trend of the load power represented by the load power data.
[0030] Step S206: Based on the adjusted parameter value of the first control parameter, the parameter value of the voltage adjustment parameter of the primary side circuit is configured, and the product of the parameter value of the configured voltage adjustment parameter and the actual voltage value of the circuit output voltage of the primary side circuit is determined as the target voltage value of the circuit output voltage, wherein the parameter value of the voltage adjustment parameter is positively correlated with the parameter value of the first control parameter.
[0031] Step S208 , adjusting the internal circuit of the primary side circuit according to the target voltage value of the circuit output voltage, so that the actual voltage value of the circuit output voltage approaches the target voltage value of the circuit output voltage.
[0032] The power supply control method in the embodiments of the present application can be applied to the field of power supply technology, and can be applied to scenarios where power supply control is performed on electronic devices. Electronic devices can be used to perform processing tasks such as computing tasks, and can be artificial intelligence (AI) electronic devices, such as AI servers. Taking AI servers as an example, as AI technology continues to iterate, various large models emerge in an endless stream. As the core carrier of computing power, AI servers place higher demands on the stability and reliability of AI server operations.
[0033] like Figure 3 As shown, the server power supply (i.e., power supply unit) exists as a separate component and independently provides power support to the server. The input of the power supply unit is daily AC power or power supply equipment in the computer room such as a power supply cabinet.
[0034] The power supply unit may include a primary side circuit and a secondary side circuit. The primary side circuit may convert the AC output voltage or DC output voltage of the power supply device into a DC input voltage of the secondary side circuit. In order to ensure the stability of the power supply, the output voltage of the primary side circuit needs to be stable at a specified voltage value.
[0035] For example, the structure inside the PSU can be as follows Figure 4 As shown in the figure, the PSU is composed of a primary-side Power Factor Correction (PFC) module and a secondary-side Low Loss Converter (LLC) module. The primary-side microcontroller unit (MCU) acts as the central nervous system brain of the primary side and leads the control of the primary side. The input signals from the primary side to the MCU include: AC and DC input voltage and current, output voltage detection of the PFC output side ( Figure 4 Similarly, the secondary control MCU, as the central nervous system brain of the secondary side, dominates the control of the secondary side. The input signals from the secondary side to the MCU include: PSU output voltage and current detection, temperature detection, current sharing detection, fan control, output protection circuit, etc. Among them, Figure 4 The 400V DC in the figure is the output of the PSU front stage (i.e., PFC module) and the input of the secondary side. The voltage regulation of 400V DC affects the stability of the PSU.
[0036] However, the aforementioned PSU, acting as a power supply unit, independently provides power to the server system. From the PSU's perspective, the server is merely a load. The PSU has no feedback on the server's overall power output and is unaware of the overall power consumption trends, i.e., how the server load changes or sudden power surges. The PSU's primary PFC module is unaware of these changes and can only dynamically adjust its output to accommodate them after the load changes occur. In certain scenarios or when the load changes rapidly, the PSU's primary PFC module may fail to respond in a timely manner, triggering protection and causing server downtime. The most significant problem with server downtime is that during dynamic adjustment, the lag in the transmission of load information at the PFC output (e.g., the 400V voltage regulator) can cause the 400V voltage to become unstable and drop below the protection threshold, leading to server downtime. Therefore, in related art, when using a PSU to power a server, the PSU may experience power outages, loss of output, and other issues, causing server downtime and impacting normal server operation. For other types of electronic devices, the power supply units therein may also experience power outages, no output, etc., causing the electronic devices to shut down, thereby affecting the normal operation of the electronic devices.
[0037] In order to at least partially solve the above problems, in this embodiment, a method of dynamically adjusting the output voltage of the primary side circuit based on the voltage control parameter is adopted. The parameter value of the voltage control parameter can be dynamically configured based on the parameter value of the first control parameter. The first control parameter is an adjustment parameter related to the load power of the electrical load on the electronic device. The change in the load power of the electrical load is a factor affecting the output voltage of the primary side circuit. Therefore, by continuously obtaining the load power data of the power supply unit of the electronic device from the mainboard control component of the electronic device, the load power data is used to characterize the change trend of the load power of the electrical load on the electronic device. According to the obtained load power data, the parameter value of the first control parameter of the primary side circuit of the power supply unit is dynamically adjusted. Through the above operation, the change of the parameter value of the first control parameter can be guaranteed. If the trend is consistent with the changing trend of the load power represented by the load power data, then the parameter value of the voltage adjustment parameter of the primary side circuit configured based on the parameter value of the adjusted first control parameter can also be kept consistent with the changing trend of the load power represented by the load power data. Then, the product of the parameter value of the configured voltage adjustment parameter and the actual voltage value of the circuit output voltage of the primary side circuit is determined as the target voltage value of the circuit output voltage, and the internal circuit of the primary side circuit is adjusted according to the target voltage value of the circuit output voltage, so that the actual voltage value of the circuit output voltage approaches the target voltage value of the circuit output voltage. The change of the output voltage of the primary side circuit can be adapted to the change of the load power of the electrical load, thereby improving the stability of the output voltage of the primary side circuit, reducing the risk of electronic equipment failure, and thus improving the safety of equipment operation.
[0038] In an embodiment of the present application, the control component that executes the above-mentioned power supply control method can be a primary-side control component, and the primary-side control component can include but is not limited to a primary-side PFC control component, etc. For example, the primary-side PFC control component can be the central system of the entire control system. The data transmitted from the mainboard control component of the electronic device can be processed by the primary-side control component to calculate the change trend of the power load and adjust the PFC control output through its own control algorithm.
[0039] The primary-side control component can continuously read the current and voltage information of each electrical load on the electronic device from the electronic device's mainboard control component. It is understood that the current and voltage information of each electrical load on the electronic device is collected by the mainboard control component of the electronic device, and the load power data of the power supply unit is obtained from the voltage and current information (i.e., the product of current and voltage equals power). The primary-side control component then communicates data with the mainboard control component of the electronic device, transmitting the load power data of the power supply unit to the primary-side control component. The load power data can represent the changing trend of the load power of the electrical loads on the electronic device.
[0040] In this embodiment, the power load of the electronic device can be considered as a whole by treating all the components inside the electronic device that require power supply. That is, the electronic device is equivalent to a load relative to the power supply unit. This load needs to power each internal component of the electronic device separately. At the same time, the mainboard control component of the electronic device can serve as the central nervous system component of the electronic device and can transmit data with the CPU, memory, hard disk, network card, fan and other components in the electronic device. The voltage and current information of these components can be collected, especially the voltage and current information of key components such as the CPU, memory, hard disk, etc. The voltage and current information can be multiplied by the current to obtain power data. The mainboard control component of the electronic device can summarize the load data of the entire electronic device and provide it to the primary side control component.
[0041] The primary-side control component can process and analyze the acquired load power data, calculate the load power change trend, and dynamically adjust the parameter value of the first control parameter of the primary-side circuit of the power supply unit based on the load power change trend, so that the change trend of the parameter value of the first control parameter is consistent with the load power change trend represented by the load power data. For example, when the load power increases, the parameter value of the first control parameter increases accordingly; when the load power decreases, the parameter value of the first control parameter decreases accordingly. The parameter value of the above-mentioned first control parameter can be used to control the output voltage of the primary-side circuit.
[0042] Here, the primary side circuit of the power supply unit may be a primary side PFC circuit, and the primary side circuit may be used to convert an input AC or DC voltage into a DC voltage to provide input for subsequent circuits.
[0043] Based on the adjusted parameter value of the first control parameter, the parameter value of the voltage adjustment parameter of the primary-side circuit is configured, and the configured parameter value of the voltage adjustment parameter is multiplied by the actual voltage value of the circuit output voltage of the primary-side circuit to obtain a target voltage value of the circuit output voltage. For example, if the parameter value of the first control parameter increases, the voltage adjustment parameter also increases, and the target voltage value obtained after multiplying by the actual voltage will also increase. The parameter value of the voltage adjustment parameter can be positively correlated with the parameter value of the first control parameter. In this embodiment, the actual voltage value of the circuit output voltage of the primary-side circuit can be 400V DC, 380V DC, etc., without specific limitation herein.
[0044] For example, the actual output voltage of the primary-side circuit is a 400V bus power supply. Based on the changing trends of the power supply cabinet input power and the output power of the electronic equipment load, the PFC bus output voltage is adjusted in advance. The parameter value of the configured voltage adjustment parameter is 1.284. The target voltage value of the circuit output voltage is equal to the actual output voltage value of the circuit multiplied by the parameter value of the configured voltage adjustment parameter. When the actual output voltage value of the circuit is 380V, the target voltage value of the circuit output voltage is 499.2V. The PFC can regulate the internal circuit according to this target voltage value, increase the output, and adjust the bus power supply to 499.2V.
[0045] The primary-side control component adjusts the internal circuitry of the primary circuit based on the determined target output voltage. This internal circuitry can be, for example, a driver circuit for a switching transistor, and is not specifically limited here. By adjusting the internal circuitry of the primary side, the operating state of the primary circuit is altered, causing the actual output voltage of the circuit to gradually approach the target voltage, thereby achieving output voltage regulation.
[0046] For example, when the load power increases, the primary side circuit (primary side PFC circuit) increases the output voltage of the circuit in advance to cope with the upcoming load mutation. When the load decreases, the primary side circuit (primary side PFC circuit) appropriately reduces the output voltage of the circuit in advance.
[0047] Through the embodiments provided by the present application, load power data of the power supply unit of the electronic device is continuously obtained from the mainboard control component of the electronic device, wherein the load power data is used to characterize the change trend of the load power of the electrical load on the electronic device; based on the obtained load power data, the parameter value of the first control parameter of the primary side circuit of the power supply unit is dynamically adjusted, wherein the change trend of the parameter value of the first control parameter is consistent with the change trend of the load power characterized by the load power data; based on the adjusted parameter value of the first control parameter, the parameter value of the voltage adjustment parameter of the primary side circuit is configured, and the product of the parameter value of the configured voltage adjustment parameter and the actual voltage value of the circuit output voltage of the primary side circuit is determined as the target voltage value of the circuit output voltage, wherein the parameter value of the voltage adjustment parameter is positively correlated with the parameter value of the first control parameter; according to the target voltage value of the circuit output voltage, the internal circuit of the primary side circuit is adjusted so that the actual voltage value of the circuit output voltage approaches the target voltage value of the circuit output voltage, thereby solving the problem in the power supply control method in the related art that the power supply unit is prone to downtime due to unstable output voltage of the primary side circuit, improving the stability of the output voltage of the primary side circuit, and thereby reducing the possibility of downtime of the power supply unit.
[0048] In some exemplary embodiments, the parameter value of the first control parameter of the primary side circuit of the power supply unit is dynamically adjusted based on the acquired load power data, including: parsing the load power data currently acquired to obtain the current load power of the power load on the electronic device; and determining the ratio of the current load power to the reference load power as the current parameter value of the first control parameter.
[0049] In this embodiment, the primary-side control component analyzes the load power data currently received from the mainboard control component to determine the current load power of the electronic device's electrical load and calculates the ratio of the current load power to a reference load power. The reference load power can be a fixed value, dynamically configured based on an average value of the historical load power of the electronic device's electrical load, or other determination methods, which are not limited in this embodiment.
[0050] In the case where the reference load power is a fixed value, the reference load power may be a pre-set fixed value. In the case where the reference load power is dynamically configured according to the average value of the historical load power of the electrical load on the electronic device, the average value of the historical load power may refer to the average value of the load power of the power supply unit received by the electrical load on the electronic device over a period of time. During the operation of the electronic device, the primary-side control component may continuously collect the historical load power data of the electrical load on the electronic device over the past period of time. For example, in units of days, the load power data at each moment of the day is collected, and then the average value of all the historical load powers of the day is calculated, and the average value is used as the reference load power. As time goes by, the above process can be repeated every day, and the historical load power data of the new day can be combined with the previous historical load data to recalculate the average value, thereby realizing the dynamic configuration of the reference load power.
[0051] If the reference load power is a fixed value, the ratio of the current load power to the fixed value is determined as the current parameter value of the first control parameter; if the reference load power is dynamically configured according to the historical load power average value, the average value of the historical load power is first calculated as the reference value, and then the ratio of the current load power to the average value of the historical load power is determined as the current parameter value of the first control parameter.
[0052] For example, when the reference load power (reference output power) is 2700 W and the current load power (real-time output power) is 2900 W, the current parameter value of the first control parameter is equal to real-time output power / reference output power, and the current parameter value of the first control parameter is 1.07.
[0053] Through this embodiment, the load power data currently obtained is analyzed to obtain the current load power, and the ratio of the current load power to the reference load power is determined as the current parameter value of the first control parameter, so that the first control parameter can more accurately reflect the changes in the load of the electronic device, provide a more accurate basis for the adjustment of the primary side circuit of the power supply unit, realize dynamic control of load changes, reduce voltage instability problems caused by delayed load information transmission, and thereby reduce the occurrence of electronic equipment downtime.
[0054] In some exemplary embodiments, the reference load power is dynamically configured based on an average value of historical load powers of the electrical load on the electronic device. After determining the ratio of the current load power to the reference load power as the current parameter value of the first control parameter, the method may further include adjusting the reference load power based on the current load power to obtain an adjusted reference load power.
[0055] After determining the current parameter value of the first control parameter by the ratio of the current load power to the reference load power, the reference load power is adjusted based on the current load power to obtain the adjusted reference load power. That is, the current load power can be included in the historical load power data, and the average value of the current load power and the historical load power of the electrical load on the electronic device is used to calculate the average value, thereby obtaining a new adjusted reference load power.
[0056] The above average value of the historical load power may refer to an average value of the load power received by the power load on the electronic device from the power supply unit within a period of time.
[0057] For example, the historical load power data is the average value of the previous N days. After obtaining the current load power, the average value of the historical load power data of the previous N days is recalculated with the current load power data to obtain the adjusted reference load power, so that it can reflect the average value of the latest historical load power data including the current load situation.
[0058] Through this embodiment, in the case where the reference load power is dynamically configured according to the historical load power average value of the electrical load on the electronic device, the reference load power is adjusted based on the current load power, so that the reference load power can be continuously updated according to historical and current load data, thereby making the calculation of the parameter value of the first control parameter more accurate, and providing a more reliable basis for the dynamic adjustment of the primary side circuit of the power supply unit.
[0059] In some exemplary embodiments, the output voltage of the primary-side circuit is also related to the output power (output voltage) of the power supply device. For example, the input of the primary PFC module of the PSU is from the power supply device. When the voltage at the input of the primary PFC module of the PSU experiences a short-term voltage drop or power outage, the PSU needs to detect the change in input voltage to adjust its output voltage. This will cause a certain delay and lag in data transmission. Especially when the input is AC, the primary PFC module of the PSU needs a certain amount of time (generally in the order of hundreds of milliseconds) to calculate the effective value of the AC voltage. Therefore, during this period, the output voltage of the PSU may experience a drop or other instability.
[0060] It should be noted that the output power of the power supply equipment is the input power of the primary side circuit, and the output voltage of the power supply equipment is the input voltage of the primary side circuit; the output power of the primary side circuit is the input power of the secondary side circuit, and the output voltage of the primary side circuit is the input voltage of the secondary side circuit; the output power of the secondary side circuit is the input power of the electrical load on the electronic device, and the output voltage of the secondary side circuit is the input voltage of the electrical load on the electronic device.
[0061] In this embodiment, the above method also includes: continuously obtaining output power data of the power supply device from the power supply device of the power supply unit, wherein the output power data is used to characterize the changing trend of the output power output by the power supply device to the primary side circuit; and dynamically adjusting the parameter value of the second control parameter of the primary side circuit according to the obtained output power data, wherein the changing trend of the parameter value of the second control parameter is consistent with the changing trend of the output power represented by the output power data.
[0062] Correspondingly, based on the parameter value of the adjusted first control parameter, the parameter value of the voltage adjustment parameter of the primary side circuit is configured, including: based on the parameter value of the adjusted first control parameter and the parameter value of the adjusted second control parameter, the parameter value of the voltage adjustment parameter is configured, wherein the parameter value of the voltage adjustment parameter is also positively correlated with the parameter value of the second control parameter.
[0063] The power supply device of the power supply unit may refer to a device that provides input voltage to the power supply unit. For example, the power supply device may be a power supply cabinet, which includes built-in detection devices for output voltage, output current, temperature, and other information. The power supply cabinet can detect changes in output and input parameters in real time, and communicate with the primary-side control component via an Inter-Integrated Circuit (I2C) bus. The output voltage and output current information is transmitted to the primary-side control component in real time so that the primary-side control component can detect changes in the input environment and adjust the output in a timely manner.
[0064] In this embodiment, the primary-side control component continuously obtains the output current and output voltage of the power supply device from the power supply unit and obtains output power data of the power supply device based on the output current and output voltage. In other words, the primary-side control component communicates data with the power supply device and transmits the output power data of the power supply device to the primary-side control component. The output power data is used to indicate the changing trend of the output power delivered by the power supply device to the primary-side circuit.
[0065] After obtaining the output power data of the power supply device (i.e., the input power data of the primary side circuit), the parameter value of the second control parameter of the primary side circuit can be dynamically adjusted according to the output power of the power supply device, so that the change trend of the parameter value of the second control parameter is consistent with the change trend of the output power represented by the output power data.
[0066] In an optional embodiment, the parameter value of the voltage adjustment parameter can be configured based on the adjusted parameter value of the first control parameter and the adjusted parameter value of the second control parameter. The parameter value of the voltage adjustment parameter is positively correlated with the parameter value of the first control parameter and the parameter value of the second control parameter. It is understandable that the parameter value of the voltage adjustment parameter can increase as the parameter value of the first control parameter and the parameter value of the second control parameter increase, and can also decrease as the parameter value of the first control parameter and the parameter value of the second control parameter decrease.
[0067] For example, the primary-side control component continuously obtains output power data from the power supply device and load power data of the power supply unit of the electronic device from the mainboard control component of the electronic device, and dynamically adjusts the parameter value of the first control parameter and the parameter value of the second control parameter according to the changing trend of the output power data and the load power data. When configuring the voltage adjustment parameter of the primary-side circuit, the parameter value of the adjusted first control parameter and the parameter value of the adjusted second control parameter are calculated to obtain the parameter value of the voltage adjustment parameter.
[0068] It should be noted that the parameter value of the voltage adjustment parameter can be configured using a function mapping method. By defining a function that takes the parameter value of the first control parameter and the parameter value of the second control parameter as input and outputs the configured value of the voltage adjustment parameter. For example, a multivariable linear regression model can be established to predict the parameter value of the voltage adjustment parameter under different combinations of the parameter values of the first control parameter and the parameter values of the second control parameter.
[0069] In another optional embodiment, the parameter value of the voltage adjustment parameter of the primary side circuit is configured based on the parameter value of the adjusted second control parameter, wherein the parameter value of the voltage adjustment parameter is positively correlated with the parameter value of the second control parameter. It can be understood that the parameter value of the voltage adjustment parameter can increase with the increase of the parameter value of the second control parameter, and can also decrease with the decrease of the parameter value of the second control parameter.
[0070] Exemplarily, when a power supply unit (PSU) is operating, the primary-side control component continuously monitors output power data transmitted from the power supply device. Upon detecting a downward trend in the output power of the power supply device, the primary-side control component adjusts the parameter value of the second control parameter and, based on the adjusted parameter value of the second control parameter, configures the parameter value of the voltage adjustment parameter of the primary-side circuit. For example, the adjusted parameter value of the second control parameter may be multiplied by a preset value to configure the parameter value of the voltage adjustment parameter. Alternatively, an algorithm model (such as a machine learning model) may be used to predict how to configure the parameter value of the voltage adjustment parameter based on the adjusted parameter value of the second control parameter. The model may be trained based on historical data to determine the relationship between changes in input power and the output voltage of the primary-side circuit, thereby providing a more accurate configuration of the parameter value of the voltage adjustment parameter. For example, by training a learning algorithm model, the adjusted parameter value of the second control parameter may be input and an appropriate parameter value of the voltage adjustment parameter may be output. Based on the adjusted value of the second control parameter, the primary-side control component further configures the value of the voltage adjustment parameter so that it is positively correlated with the value of the second control parameter. This means that a decrease in the value of the second control parameter will result in a corresponding adjustment in the value of the voltage adjustment parameter, proactively addressing potential voltage drops caused by a decrease in input power in the primary-side circuit. If the adjusted value of the second control parameter causes the voltage adjustment parameter to decrease, the primary-side control component will adjust the primary-side circuit's control strategy based on this change, appropriately increasing the PFC circuit's output voltage to compensate for the impending input power drop. In this way, the PSU primary-side circuit can proactively respond, avoiding downtime in electronic equipment due to power supply voltage fluctuations and achieving true voltage regulation.
[0071] Through this embodiment, continuous monitoring of the output power data of the power supply device and dynamic adjustment of the second control parameter of the primary side circuit can significantly improve the stability and efficiency of the power supply of the electronic device, and reduce the risk of performance degradation or downtime of the electronic device due to improper power supply management.
[0072] In some exemplary embodiments, the parameter value of the second control parameter of the primary side circuit is dynamically adjusted based on the acquired output power data, including: parsing the output power data currently acquired to obtain the current output power output by the power supply device to the primary side circuit; and determining the ratio of the current output power to the reference output power as the current parameter value of the second control parameter.
[0073] In this embodiment, the primary-side control component parses the output power data currently obtained from the power supply device to obtain the output power data output by the power supply device to the primary-side circuit. After receiving the output power data sent by the power supply device, the primary-side control component parses the output power data to obtain the current output power, and calculates the ratio of the current output power to the reference output power. Here, the reference output power can be a fixed value, or it can be dynamically configured based on the average value of the historical output power output by the power supply device to the primary-side circuit, or it can be determined by other methods, which are not limited in this embodiment.
[0074] By calculating the ratio of the current output power to the reference output power, the deviation between the power supply condition and the expected or historical average power supply capacity can be evaluated. If the current output power is higher than the reference output power, the value of the second control parameter will be increased, otherwise it will be decreased.
[0075] In the case where the reference output power is a fixed value, the reference output power may be a pre-set fixed value. In the case where the reference output power is dynamically configured according to the average value of the historical output power data output by the power supply device to the primary side circuit, the average value of the historical output power may refer to the average value of the output power of the power supply device received by the powered device over a period of time. During the operation of the power supply device, the primary side control component may continuously collect the historical output power data output by the power supply device to the primary side circuit over the past period of time. For example, on a daily basis, the output power data at each moment of the day is collected, and then the average value of all the historical output power data of the day is calculated, and the average value is used as the reference output power. As time goes by, the above process may be repeated every day, and the historical output power data of the new day may be combined with the previous historical output power data to recalculate the average value, thereby achieving dynamic configuration of the reference output power.
[0076] If the reference output power is a fixed value, the ratio of the current output power to the fixed value is determined as the current parameter value of the first control parameter; if the reference output power is dynamically configured according to the historical output power average value, the average value of the historical output power is first calculated as the reference value, and then the ratio of the current output power to the average value of the historical output power is determined as the current parameter value of the first control parameter.
[0077] For example, when the reference output power (reference input power of the primary side circuit) is 100W and the current output power (real-time input power of the primary side circuit) is 120W, the current parameter value of the second control parameter is equal to the real-time input power / reference input power, and the current parameter value of the second control parameter is 1.2.
[0078] Through this embodiment, the parameter value of the second control parameter of the primary side circuit is dynamically adjusted according to the obtained output power, which significantly improves the response speed and accuracy to the output power changes of the power supply equipment. In addition, by parsing the output power data and calculating the ratio of the output power to the reference output power, the control parameters of the primary side circuit can be adjusted, thereby avoiding output voltage instability caused by external power supply fluctuations and reducing the risk of downtime of electronic equipment due to power supply problems.
[0079] In some exemplary embodiments, the reference output power is dynamically configured based on an average of historical output powers of the power supply device to the primary-side circuit. Accordingly, after determining the ratio of the current output power to the reference output power as the current parameter value of the second control parameter, the method further includes adjusting the reference output power based on the current output power to obtain an adjusted reference output power.
[0080] After determining the current parameter value of the second control parameter, the reference output power is adjusted based on the current output power to obtain an adjusted reference output power. That is, the current output power can be included in the historical output power data, and the average value can be recalculated using the current output power and the current historical output power to obtain a new historical output power. The average value of the historical output power can refer to the average value of the output power of the power supply device received by the primary-side circuit over a period of time.
[0081] For example, the historical output power is the average value of the previous N days. After obtaining the current output power, the average value of the historical output power of the previous N days is recalculated with the current output power to obtain the adjusted reference output power so that it can reflect the average value of the historical output power including the current output power.
[0082] Through this embodiment, the reference output power is dynamically adjusted based on the current output power, which significantly enhances the adaptability of the PSU to changes in the output power of the power supply equipment. In addition, through dynamic adjustment of historical data, the flexibility and predictability of the primary side circuit of the PSU are improved, ensuring that the output voltage can remain stable even when the power supply conditions fluctuate.
[0083] In some exemplary embodiments, configuring the parameter value of the voltage adjustment parameter based on the adjusted parameter value of the first control parameter and the adjusted parameter value of the second control parameter includes: configuring the product of the adjusted parameter value of the first control parameter and the adjusted parameter value of the second control parameter as the parameter value of the voltage adjustment parameter.
[0084] In this embodiment, the parameter value of the adjusted first control parameter and the parameter value of the adjusted second control parameter are multiplied. Based on the result of the above multiplication operation, the parameter value of the voltage adjustment parameter of the primary side circuit of the PSU is updated, and the product of the updated voltage adjustment parameter value and the actual voltage value of the circuit output voltage of the primary side circuit is determined as the target voltage value of the circuit output voltage.
[0085] For example, Figure 5 As shown, the power supply device transmits input voltage change data or input power of the primary-side circuit to the primary-side control component to determine whether the input voltage has dropped, power has been lost, or the input power has decreased. If so, the parameter value of the first control parameter (K1) is increased. If the input voltage has not dropped, power has been lost, or the input power has not decreased, that is, the input voltage or input power has increased, the parameter value of the first control parameter (K1) is decreased to obtain an adjusted parameter value of the first control parameter. The mainboard control component transmits load power change data to the primary-side control component to determine whether the load power has increased. If so, the parameter value of the second control parameter (K2) is decreased. If so, the parameter value of the second control parameter (K2) is increased to obtain an adjusted parameter value of the second control parameter. After obtaining the adjusted parameter values of the first and second control parameters, the primary-side control component configures the product of the adjusted parameter values of the first and second control parameters as the parameter value of the voltage adjustment parameter, and adjusts the output voltage of the voltage supply unit in advance based on changes in the parameter value K of the voltage adjustment parameter.
[0086] For example, the parameter value of the adjusted first control parameter (output parameter K1) is 1.07, the parameter value of the adjusted second control parameter (input parameter K2) is 1.2, and the parameter value of the voltage adjustment parameter (PFC control parameter K) is equal to the parameter value of the adjusted first control parameter multiplied by the parameter value of the adjusted second control parameter, resulting in a parameter value of the voltage adjustment parameter of 1.284.
[0087] Through this embodiment, the parameter value of the voltage adjustment parameter is configured by multiplying the parameter value of the adjusted first control parameter and the parameter value of the second control parameter, thereby realizing the comprehensive response capability of the PSU primary side circuit to changes in power supply capacity and load demand, so that the PSU primary side circuit can provide a more stable and reliable power output, effectively reducing the risk of equipment downtime caused by power supply fluctuations or load changes of electronic equipment.
[0088] In some exemplary embodiments, configuring the parameter value of the voltage adjustment parameter based on the adjusted parameter value of the first control parameter and the adjusted parameter value of the second control parameter includes: configuring the weighted sum of the parameter value of the adjusted first control parameter and the parameter value of the adjusted second control parameter as the parameter value of the voltage adjustment parameter.
[0089] In this embodiment, the parameter value of the adjusted first control parameter and the parameter value of the adjusted second control parameter are weighted and processed, and the weighting coefficient can be selected according to actual conditions. According to the result of the weighted processing, the parameter value of the voltage adjustment parameter of the primary side circuit of the PSU is updated, and the product of the updated voltage adjustment parameter value and the actual voltage value of the circuit output voltage of the primary side circuit is determined as the target voltage value of the circuit output voltage.
[0090] In one optional embodiment, the primary-side PFC control component continuously obtains input voltage and input power information from the power supply device, as well as load voltage and load current data of the power load transmitted by the mainboard control component. Based on the input voltage, input power, load voltage, and load current data, a first control parameter reflecting the load power variation trend of the electronic device and a second control parameter reflecting the input power variation trend of the power supply device are obtained. The adjusted parameter values of the first control parameter and the second control parameter are then weighted using a preset weighting factor, and the weighted sum is configured as the parameter value of the voltage adjustment parameter of the PSU primary-side circuit.
[0091] Through this embodiment, the weighted sum of the parameter value of the adjusted first control parameter and the parameter value of the adjusted second control parameter is configured as the parameter value of the voltage adjustment parameter, thereby enhancing the dynamic responsiveness of the primary side circuit of the PSU, and being able to perceive and predict the dynamic changes at both ends of the power supply and the load in real time. Through weighted sum calculation, more accurate control of the output voltage is achieved, further improving the output voltage stability of the primary side circuit of the PSU, and reducing the risk of electronic equipment downtime due to power supply or load problems.
[0092] In some exemplary embodiments, the above method also includes: continuously obtaining output voltage data of the power supply device from the power supply device of the power supply unit, wherein the output voltage data is used to characterize the changing trend of the input voltage output by the power supply device to the primary side circuit; parsing the output voltage data currently obtained to obtain the current output voltage output by the power supply device to the primary side circuit; when the voltage difference between the current output voltage and the reference output voltage is greater than or equal to the voltage difference threshold, adjusting the internal circuit of the primary side circuit to increase the actual voltage value of the circuit output voltage, wherein the reference output voltage is the output voltage obtained by parsing the output voltage data obtained last time.
[0093] In the embodiments of the present application, the output voltage trend may refer to the temporal fluctuation of the output voltage of the power supply device to the primary circuit (i.e., the input voltage of the primary circuit). By continuously collecting output voltage data, the primary-side control component can predict future voltage fluctuations, allowing the primary circuit to adjust its output voltage in advance.
[0094] The reference output voltage may be an output voltage derived from the analysis of previously acquired output voltage data, serving as a reference point for comparing the current output voltage with the previously acquired output voltage. The voltage difference threshold may be a critical value at which the primary-side circuit of the PSU responds to the output voltage, and the voltage difference threshold may be a preset value.
[0095] In an optional embodiment, the primary side control component continuously receives output voltage data from the power supply device through I2C or other communication protocols. Each time new output voltage data is received, the primary side control component parses the output voltage data and extracts the current output voltage. The parsing process can be based on the signal processing algorithm inside the primary side control component. The current output voltage parsed is compared with the reference output voltage obtained in the previous parsing, and the voltage difference between the two is calculated. When the detected voltage difference is greater than or equal to the set voltage difference threshold, the primary side control component adjusts the internal circuit of the primary side circuit to respond to the downward trend of the input voltage of the primary side circuit by enhancing the actual voltage value of the circuit output voltage. The above adjustment process can be based on the internal algorithm of the primary side control component.
[0096] Through this embodiment, output voltage data is continuously obtained from the PSU power supply equipment, and when it is detected that the voltage difference between the current output voltage and the reference output voltage exceeds the voltage difference threshold, the internal circuit of the primary side circuit is adjusted to increase the actual voltage value of the circuit output voltage, so that the circuit can take quick measures to maintain the stability of the output voltage when the input voltage of the primary side circuit changes adversely, thereby reducing the risk of electronic equipment downtime due to unstable power supply voltage.
[0097] In some exemplary embodiments, the above method also includes: predicting the parameter value of the voltage adjustment parameter within a specified time period after the current moment according to a parameter change curve corresponding to the voltage adjustment parameter, wherein the parameter change curve is drawn according to the historical parameter value of the voltage adjustment parameter; when it is predicted that the parameter value of the voltage adjustment parameter will show a downward trend after the specified moment, increasing the parameter value of the configured voltage adjustment parameter at the specified moment.
[0098] In this embodiment, a parameter change curve is plotted based on the collected historical values of the voltage adjustment parameter. This parameter change curve reflects the changes in the voltage adjustment parameter over a period of time. Based on this parameter change curve, the trend of the voltage adjustment parameter value within a specified time period after the current moment is predicted.
[0099] When it is predicted that the parameter value of the voltage adjustment parameter will decrease after a specified time in the future, the primary control component increases the parameter value of the voltage adjustment parameter at the specified time to respond in advance to potential power supply reduction or increase in electronic equipment load demand, making the output voltage more stable.
[0100] For example, as time accumulates, the primary-side control component can draw a change curve of the parameter value of the first control parameter and the parameter value of the second control parameter (i.e., a change curve of the parameter value of the voltage adjustment parameter) based on the data collected in the past. Since the operating mode of the electronic device is certain, the change curve also has a certain trend to follow and a certain regularity. Similarly, the power supply equipment also has a certain regularity (for example, during the peak power consumption period during the day, the power supply of the entire power grid will be relatively low, and the input power that can be supplied will also decrease. At night, the power consumption will be small, and the electronic equipment can use this feature to increase the power supply). Therefore, it is necessary to capture and collect data to draw a change curve of the parameter value of the first control parameter and the parameter value of the second control parameter. The collected data can be used to create a big data model to effectively predict the changes at the next moment, and action can be taken in advance, truly achieving the purpose of predictive early voltage stabilization.
[0101] Through this embodiment, a parameter change curve is drawn for the historical parameter values of the voltage adjustment parameter, and the future trend of the parameter value within a specified time period is predicted based on the parameter change curve. When it is predicted that the parameter value of the voltage adjustment parameter will decrease in the future, the parameter value of the voltage adjustment parameter can be actively increased at the specified time, thereby improving the response speed of the PSU to power supply fluctuations and load changes, and reducing the risk of electronic equipment downtime due to voltage instability.
[0102] In some exemplary embodiments, the method further includes: plotting a parameter change curve based on the parameter values of the voltage adjustment parameter recorded during the current time period, with a specified time period as a unit, to obtain a current change curve; and superimposing the current change curve with the parameter change curve to obtain an updated parameter change curve. Here, the specified time period may be a time interval for periodically recording and analyzing the parameter values of the voltage adjustment parameter.
[0103] The parameter value changes of the voltage adjustment parameters are continuously monitored within a specified time period. The collected data is used to draw the change curve within the current time period. The drawn current change curve is superimposed with the existing parameter change curve to obtain a new parameter change curve.
[0104] In an optional embodiment, the primary-side control component divides the collected data into two units: day and year. The data collected on the first day can be plotted into a curve, and the curve plotted on the second day can be superimposed with the curve obtained on the first day (the data at each moment is averaged), thus drawing a new superimposed curve. Similarly, the curve after the Nth day will obtain a curve reflecting these N days. In this way, as time accumulates, this curve can reflect the data changes of each day more and more accurately. The longer the time, the more reliable the data; and by analogy, a curve with one year as the unit can also be drawn.
[0105] For example, Figure 6 As shown, taking the data collected 24 hours a day as an example, it can be seen that the parameter value (K value) of the voltage adjustment parameter is the largest at the peak point A, and the parameter value (K value) of the voltage adjustment parameter is the smallest at the trough point B. Then, according to the prediction of the change curve, the parameter value of the overall voltage adjustment parameter will decrease after point A. Therefore, the PSU can intervene in advance at point A and increase the parameter value of the voltage adjustment parameter to offset the upcoming decrease in the parameter value of the voltage adjustment parameter, thus realizing the true principle of early voltage regulation.
[0106] Through this embodiment, the current change curve of the voltage adjustment parameter is continuously recorded and drawn in units of specified time length, and then the current change curve is superimposed and updated with the historical parameter change curve, thereby realizing the dynamic update of the parameter change curve and improving the accuracy and timeliness of the prediction model. The updated parameter change curve can better reflect the actual change trend of the voltage adjustment parameter of the primary side circuit of the PSU.
[0107] According to another aspect of an embodiment of the present application, a power supply unit is further provided. The power supply unit may be the power supply unit in any of the aforementioned embodiments, which has been described and will not be repeated here.
[0108] In this embodiment, the power supply unit may include a primary-side circuit and a secondary-side circuit. The primary-side circuit is configured to convert the AC output voltage or DC output voltage of the power supply device into a DC input voltage for the secondary-side circuit; and the secondary-side circuit is configured to convert the DC input voltage provided by the primary-side circuit into a DC input voltage for an electrical load on an electronic device to which the power supply unit belongs.
[0109] The power supply unit may also include: a primary-side control component, used to continuously obtain load power data of the power supply unit from the mainboard control component of the electronic device, wherein the load power data is used to characterize the change trend of the load power of the electrical load on the electronic device; dynamically adjust the parameter value of the first control parameter of the primary side circuit according to the obtained load power data, wherein the change trend of the parameter value of the first control parameter is consistent with the change trend of the load power represented by the load power data; based on the adjusted parameter value of the first control parameter, configure the parameter value of the voltage adjustment parameter of the primary side circuit, and determine the product of the parameter value of the configured voltage adjustment parameter and the actual voltage value of the circuit output voltage of the primary side circuit as the target voltage value of the circuit output voltage, wherein the parameter value of the voltage adjustment parameter is positively correlated with the parameter value of the first control parameter; adjust the internal circuit of the primary side circuit according to the target voltage value of the circuit output voltage, so that the actual voltage value of the circuit output voltage approaches the target voltage value of the circuit output voltage.
[0110] The above-mentioned primary-side control component can be the central system of the entire control system. The data transmitted from the mainboard control component of the electronic device and the power supply equipment can be processed by the primary-side control component to calculate the changing trends of the input voltage and power load, and adjust the control output of the primary-side circuit (such as the primary-side PFC circuit) through its own control algorithm.
[0111] Figure 7 is a schematic structural diagram of an optional power supply unit provided according to an embodiment of the present application, such as Figure 7 As shown, the primary-side control component transmits data with the power supply equipment (such as the power supply cabinet) to transmit the changes in the input voltage of the primary-side circuit. The primary-side control component transmits data with the primary-side circuit (such as the primary-side PFC circuit) and implements the control strategy. The primary-side control component transmits data (transmits load changes) and implements the control strategy with the server load (an example of the power load on the aforementioned electronic device) through the server's mainboard control component. The power supply equipment transmits the input voltage to the primary-side circuit of the power supply unit. The primary-side circuit then transmits the processed voltage to the secondary-side circuit (such as the secondary-side LLC circuit). The secondary-side circuit transmits the voltage required by the server load to the server load.
[0112] Through this embodiment, the primary side circuit converts the input voltage of the power supply device into a DC voltage suitable for the secondary side circuit, and the secondary side circuit further converts this DC voltage into a stable voltage required by the power load; the primary side control component dynamically adjusts the first control parameter of the primary side circuit by continuously obtaining load power data, configures the voltage adjustment parameter according to the changed first control parameter, determines the target voltage value of the circuit output voltage, and adjusts the internal circuit of the primary side circuit accordingly, so that the actual voltage value approaches the target voltage value, which not only improves the dynamic adjustment capability of the PSU primary side circuit, but also ensures that the output voltage can remain stable even in the case of sudden load changes, greatly reducing the risk of downtime of electronic equipment due to power supply problems.
[0113] In some exemplary embodiments, the primary-side control component is further used to parse the load power data currently acquired to obtain the current load power of the electrical load on the electronic device; and determine the ratio of the current load power to the reference load power as the current parameter value of the first control parameter; wherein the reference load power is a fixed value, or the reference load power is dynamically configured according to the average value of the historical load power of the electrical load on the electronic device.
[0114] In some exemplary embodiments, the reference load power is dynamically configured based on an average value of historical load powers of the electrical load on the electronic device. The primary-side control component is further configured to, after determining a ratio of the current load power to the reference load power as the current parameter value of the first control parameter, adjust the reference load power based on the current load power to obtain an adjusted reference load power.
[0115] In some exemplary embodiments, the primary-side control component is further used to continuously obtain output power data of the power supply device from the power supply device of the power supply unit, wherein the output power data is used to characterize the changing trend of the output power output by the power supply device to the primary-side circuit; dynamically adjust the parameter value of the second control parameter of the primary-side circuit according to the obtained output power data, wherein the changing trend of the parameter value of the second control parameter is consistent with the changing trend of the output power represented by the output power data; configure the parameter value of the voltage adjustment parameter based on the adjusted parameter value of the first control parameter and the adjusted parameter value of the second control parameter, wherein the parameter value of the voltage adjustment parameter is also positively correlated with the parameter value of the second control parameter.
[0116] In some exemplary embodiments, the currently acquired output power data is parsed to obtain the current output power of the power supply device to the primary-side circuit; and the ratio of the current output power to a reference output power is determined as the current parameter value of the second control parameter. The reference output power is a fixed value, or the reference output power is dynamically configured based on an average of historical output powers of the power supply device to the primary-side circuit.
[0117] In some exemplary embodiments, the reference output power is dynamically configured based on an average of historical output powers output by the power supply device to the primary-side circuit. The primary-side control component is further configured to, after determining a ratio of the current output power to the reference output power as the current parameter value of the second control parameter, adjust the reference output power based on the current output power to obtain an adjusted reference output power.
[0118] In some exemplary embodiments, the primary-side control component is further configured to configure a product of a parameter value of the adjusted first control parameter and a parameter value of the adjusted second control parameter as a parameter value of the voltage adjustment parameter.
[0119] In some exemplary embodiments, the primary-side control component is further configured to configure a weighted sum of the adjusted parameter value of the first control parameter and the adjusted parameter value of the second control parameter as the parameter value of the voltage adjustment parameter.
[0120] In some exemplary embodiments, the primary-side control component is further used to continuously obtain output voltage data of the power supply device from the power supply device of the power supply unit, wherein the output voltage data is used to characterize the changing trend of the input voltage output by the power supply device to the primary-side circuit; the output voltage data currently obtained is analyzed to obtain the current output voltage output by the power supply device to the primary-side circuit; when the voltage difference between the current output voltage and the reference output voltage is greater than or equal to the voltage difference threshold, the internal circuit of the primary-side circuit is adjusted to increase the actual voltage value of the circuit output voltage, wherein the reference output voltage is the output voltage obtained by analyzing the output voltage data obtained last time.
[0121] In some exemplary embodiments, the primary-side control component is further used to predict the parameter value of the voltage adjustment parameter within a specified time period after the current moment according to a parameter change curve corresponding to the voltage adjustment parameter, wherein the parameter change curve is drawn according to the historical parameter value of the voltage adjustment parameter; when it is predicted that the parameter value of the voltage adjustment parameter will show a downward trend after the specified moment, the parameter value of the configured voltage adjustment parameter is adjusted upward at the specified moment.
[0122] In some exemplary embodiments, the primary side control component is also used to draw a parameter change curve based on the parameter value of the voltage adjustment parameter recorded in the current time period in units of a specified time length to obtain a current change curve; and superimpose the current change curve with the parameter change curve to obtain an updated parameter change curve.
[0123] According to another aspect of the embodiments of the present application, an electronic device is further provided. The electronic device may be the electronic device in any of the aforementioned embodiments, which have been described above and will not be repeated here.
