Description

Technical Field

[0001] The present application relates to the field of data processing, and in particular to a data processing method, device, power supply circuit, chip, semiconductor component, electronic device and storage medium. Background Art

[0002] With the continuous development of the internet industry in recent years, server performance has been continuously improved and optimized, and products such as CPUs (processors), GPUs (graphics processing units), and memory have also been updated and iterated. With the upgrade of major hardware, the current demand for power supplies has also increased, making power supply solutions more complex than before.

[0003] There are many power supply solutions available for servers, depending on the load's output voltage. For example, a step-down circuit on a motherboard can be powered by a POL (Point of Load). When the load's output voltage matches the input voltage, EFUSE (electronic fuses) are typically used. For example, the CPU, GPU, and memory in a server are all powered by EFUSEs.

[0004] Current single-phase EFUSE solutions typically have a current capacity of around 50A. However, with the development of CPUs, GPUs, memory, and other devices, the current demand continues to increase, making single-phase EFUSE unavailable. This necessitates the use of two-phase EFUSEs to increase current capacity. Ideally, two-phase EFUSEs would be connected in parallel to evenly divide the current. However, due to factors such as current accuracy and layout, achieving complete current sharing between the two phases of EFUSE is difficult.

[0005] If the current difference between the two phases of the EFUSE is too large, one of the two phases will reach the overcurrent protection point of the single-phase EFUSE first, causing the overcurrent protection to be triggered incorrectly, causing a power outage and endangering normal system operation. However, the response of overcurrent protection triggered by phase uneven current is the same as that triggered by non-phase uneven current. Therefore, determining whether the overcurrent protection is triggered by phase uneven current becomes the key to quickly locating the problem. Summary of the Invention

[0093] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0094] In order to accurately identify overcurrent protection caused by uneven current between phases when power is supplied by two-phase, three-phase or even more-phase EFUSE, an embodiment of the present application provides a data processing method, such as Figure 1 As shown, the method includes:

[0095] Step 101: Obtain voltage analog signals of at least two electronic fuses.

[0096] Read the voltage analog signal of the electronic fuse from the IMON pin of the electronic fuse.

[0097] Step 102: Perform analog-to-digital conversion on the voltage analog signal to obtain a corresponding voltage digital signal.

[0098] Perform analog-to-digital conversion on the voltage analog signal and convert it into a voltage digital signal that can be processed by a computer.

[0099] Analog-to-digital conversion is usually achieved through an analog-to-digital converter.

[0100] In this embodiment, a successive approximation type, a parallel comparison type, an integral type, or other types of analog-to-digital converters may be used. In other implementations, any analog-to-digital converter that can perform analog-to-digital conversion may be used.

[0101] Step 103: If a target condition is determined to be satisfied based on the voltage digital signals of the at least two electronic fuses and at least one voltage digital signal is greater than a preset voltage, log data is generated. The target condition includes a difference of at least one order of magnitude between the at least two voltage digital signals, the preset voltage is determined based on the overcurrent protection voltage, and the log data includes at least a fault indicator, indicating that the at least two electronic fuses have uneven current distribution between phases and have triggered overcurrent protection.

[0102] If there are at least two voltage digital signals that differ by at least one order of magnitude, it is determined that the target condition is met.

[0103] If the target condition is met and at least one voltage digital signal is greater than a preset voltage, it is determined that the electronic fuse has triggered overcurrent protection due to uneven current between phases, and log data is generated.

[0104] The preset voltage is determined based on the overcurrent protection voltage, and the overcurrent protection voltage is converted into a digital form to obtain a preset voltage that can be processed by a computer.

[0105] In this embodiment, the difference between at least two voltage digital signals is at least one order of magnitude, which means that the difference between the two voltage digital signals is large, or the ratio formed by the two voltage digital signals is large.

[0106] Whether the difference between two voltage digital signals is large can be determined by comparing the difference with a preset threshold. For example, the preset threshold is 500. If two voltage digital signals are obtained, namely, 1000 and 2000, and the difference is 1000, which is greater than the preset threshold, then it is determined that the difference between the two voltage digital signals is one order of magnitude.

[0107] To determine whether the ratio between two voltage digital signals is large, the larger voltage digital signal can be divided by the smaller voltage digital signal and the resulting ratio compared to a preset threshold. For example, the preset threshold is 120%. If two voltage digital signals are obtained, namely, 1300 and 1000, and the ratio is 130%, which is greater than the preset threshold, then the difference between the two voltage digital signals is determined to be one order of magnitude.

[0108] It should be pointed out that, to determine whether the two voltage digital signals differ by at least one order of magnitude, other methods can be used, or other data can be added to the above two methods for comprehensive judgment, which can be set based on specific needs.

[0109] In this embodiment, the generated log data includes at least a fault identifier, which indicates that the at least two electronic fuses have uneven current distribution between phases and have triggered overcurrent protection. The fault identifier can be set in the form of a numerical value, a string, or other similar format. For example, if the fault identifier is set to a numerical value of 1, it indicates that the electronic fuses have uneven current distribution between phases and have triggered overcurrent protection. For another example, if the fault identifier is set to a string of "error," it indicates that the electronic fuses have uneven current distribution between phases and have triggered overcurrent protection.

[0110] It should be noted that the log data may also include other more data, such as the voltage digital signal of each electronic fuse, the timestamp when the fault occurs, the type of protection action (such as alarm and / or trip), and other data.

[0111] Step 104: Store the log data into a target storage area, where the target storage area at least includes a register.

[0112] The log data is stored in the target storage area, and the log data in the target storage area can be read later for adjustment or maintenance.

[0113] In this embodiment, the target storage area includes at least registers. In other implementations, the target storage area may also include a firmware storage area, a flash memory, or other storage areas.

[0114] In a system powered by multi-phase electronic fuses, the overcurrent protection voltage is usually set by dividing the overcurrent protection voltage by the number of electronic fuses to obtain the overcurrent protection voltage of each electronic fuse. However, since multi-phase electronic fuses may have uneven current between phases, the overall overcurrent protection voltage is not reached, but the voltage of the single-phase electronic fuse reaches the overcurrent protection voltage, thereby triggering the overcurrent protection. For example, if the power is supplied by two-phase electronic fuses and the overcurrent protection voltage is 2V, the overcurrent protection voltage of the single-phase electronic fuse is 1V. During the power supply process, the two-phase electronic fuses have uneven current between phases. The voltage of one electronic fuse is 0.5V, and the voltage of the other electronic fuse is 1.2V. The total voltage is 1.7V, which is less than the overall overcurrent protection voltage of 2V. However, the electronic fuse with a voltage of 1.2V exceeds the overcurrent voltage of the single-phase electronic fuse by 1V, causing the overcurrent protection to be triggered. However, because current systems powered by multi-phase electronic fuses all connect multiple fuses in parallel, and the device response to overcurrent protection due to interphase current imbalance is indistinguishable from actual overcurrent protection, it is currently impossible to accurately determine whether overcurrent protection is caused by interphase current imbalance. In the aforementioned solution, an analog voltage signal from the electronic fuse is read from its IMON pin. This analog voltage signal is then converted to a digital voltage signal using an analog-to-digital converter. The electronic fuse's status is monitored based on the digital voltage signal. If at least two digital voltage signals differ by at least one order of magnitude and at least one digital voltage signal is greater than a preset voltage, the electronic fuse is determined to have triggered overcurrent protection due to interphase current imbalance. This approach accurately determines whether overcurrent protection in systems powered by multi-phase electronic fuses is caused by interphase current imbalance. Once the overcurrent protection is determined to be caused by interphase current imbalance, log data is generated and stored in a target storage area, providing data support for subsequent adjustments and maintenance.

[0115] In an example of the present application, a data processing method is also provided, such as Figure 2 As shown, the determining that the target condition is met based on the voltage digital signals of the at least two electronic fuses includes:

[0116] Step 201 : Determine a difference between a first voltage digital signal and a second voltage digital signal, wherein the first voltage digital signal is a maximum value of the voltage digital signals and the second voltage digital signal is a minimum value of the voltage digital signals.

[0117] The maximum voltage digital signal among the voltage digital signals is determined as the first voltage digital signal, and the minimum voltage digital signal among the voltage digital signals is determined as the second voltage digital signal. The difference between the first voltage digital signal and the second voltage digital signal is then calculated to obtain the maximum difference between any two voltage digital signals of the electronic fuses.

[0118] Step 202: If the difference is greater than a preset threshold, it is determined that the target condition is met.

[0119] For example, the preset threshold is set to 500. In a system powered by two electronic fuses, the voltage digital signals of the two electronic fuses are obtained as 2048 and 3072, respectively. The first digital voltage signal is determined to be 3072, and the second digital voltage signal is determined to be 2048. The difference between the first digital voltage signal and the second digital voltage signal is calculated to be 1024, which is greater than the preset threshold of 500. Therefore, it is determined that the target condition is met.

[0120] For another example, the preset threshold is set to 800. In a system powered by three-phase electronic fuses, the voltage digital signals of the three electronic fuses are obtained as 2048, 3072, and 3278, respectively. The first digital voltage signal is determined to be 3278, and the second digital voltage signal is determined to be 2048. The difference between the first and second digital voltage signals is calculated to be 1230, which is greater than the preset threshold of 800. Therefore, it is determined that the target condition is met.

[0121] In the above solution, by comparing the maximum difference between each pair of digital voltage signals from a multi-phase electronic fuse with a preset threshold, it is possible to accurately determine whether two digital voltage signals differ by at least an order of magnitude. By directly calculating the maximum difference between each phase's digital voltage signals and comparing it with the preset threshold, complex algorithms are avoided, significantly reducing the amount of computation required and lowering the demand for hardware processing performance.

[0122] In an example of the present application, a data processing method is also provided, such as Figure 3 As shown, the determining that the target condition is met based on the voltage digital signals of the at least two electronic fuses includes:

[0123] Step 301 : Determine a difference between a first voltage digital signal and a second voltage digital signal, wherein the first voltage digital signal is a maximum value of the voltage digital signals and the second voltage digital signal is a minimum value of the voltage digital signals.

[0124] Similarly, the maximum voltage digital signal among the voltage digital signals is determined as the first voltage digital signal, and the minimum voltage digital signal among the voltage digital signals is determined as the second voltage digital signal. The difference between the first voltage digital signal and the second voltage digital signal is then calculated to obtain the maximum difference between any two voltage digital signals of the electronic fuses.

[0125] Step 302: Determine an imbalance degree based on the difference and the voltage digital signals of the at least two electronic fuses.

[0126] In this embodiment, the mean, median, maximum, and minimum values ​​can be determined based on the digital voltage signal of the electronic fuse, and the difference can be divided by at least one of the aforementioned values ​​to determine the degree of imbalance. In other embodiments, other values ​​determined based on the digital voltage signal of the electronic fuse can also be used, and can be set based on specific needs.

[0127] Step 303: If the imbalance degree is greater than a preset threshold, it is determined that the target condition is met.

[0128] In this embodiment, the imbalance degree and the preset threshold are both percentage values. For example, if the imbalance degree is 30%, the preset threshold is set to 20%.

[0129] In the above-mentioned solution, the maximum difference between the two digital voltage signals of the multiphase electronic fuses is normalized by dividing it by a value determined based on the digital voltage signals (such as the mean, median, maximum, or minimum), thereby obtaining a degree of imbalance. This achieves adaptive adjustment of the dynamic range. This difference is associated with the current system operating conditions, allowing the preset threshold to automatically scale with the voltage amplitude. This avoids false or missed detections caused by sensitivity imbalances in fixed thresholds under different operating conditions, further improving the accuracy of determining whether two digital voltage signals differ by at least an order of magnitude.

[0130] In an example of the present application, a data processing method is further provided, wherein determining the degree of imbalance based on the difference and the voltage digital signals of the at least two electronic fuses comprises:

[0131] The degree of imbalance is determined based on the difference and the first voltage digital signal.

[0132] The degree of imbalance can be determined based on the following formula :

[0133]

[0134] in, is the difference between the first voltage digital signal and the second voltage digital signal, is the first voltage digital signal.

[0135] In the above solution, the maximum difference between the two digital voltage signals of the multiphase electronic fuse is divided by the first digital voltage signal (i.e., the maximum voltage digital signal) to normalize the signal to obtain the imbalance degree, thus achieving adaptive adjustment of the dynamic range. By correlating the maximum difference with the peak voltage, the imbalance degree can represent the difference between the peak voltage and the maximum difference, further improving the accuracy of determining whether two digital voltage signals differ by at least an order of magnitude.

[0136] In an example of the present application, a data processing method is also provided, such as Figure 4 As shown, determining the imbalance based on the difference and the voltage digital signals of the at least two electronic fuses includes:

[0137] Step 401: Determine a voltage digital signal average based on the voltage digital signals of the at least two electronic fuses.

[0138] Step 402: Determine the degree of imbalance based on the difference and the average value of the voltage digital signal.

[0139] The degree of imbalance can be determined based on the following formula :

[0140]

[0141] in, is the difference between the first voltage digital signal and the second voltage digital signal, is the mean value of the voltage digital signal.

[0142] In the above solution, the maximum difference between the two digital voltage signals of the multi-phase electronic fuse is divided by the first digital voltage signal (i.e., the maximum digital voltage signal) to normalize the signal to obtain the degree of imbalance, thus achieving adaptive adjustment of the dynamic range. Since the mean of the digital voltage signal reflects the overall operating point of each phase voltage, associating the degree of imbalance with the overall operating point of each phase voltage can more sensitively capture the distribution deviation of each phase voltage. The mean calculation also smooths single-phase transient noise or small anomalies, reducing the probability of false detection caused by local disturbances and further improving the accuracy of determining whether two digital voltage signals differ by at least an order of magnitude.

[0143] In an example of the present application, a data processing method is also provided, such as Figure 5 As shown, the determining that the target condition is met based on the voltage digital signals of the at least two electronic fuses includes:

[0144] Step 501 : Determine a difference between a first voltage digital signal and a second voltage digital signal, wherein the first voltage digital signal is a maximum value of the voltage digital signals and the second voltage digital signal is a minimum value of the voltage digital signals.

[0145] Similarly, the maximum voltage digital signal among the voltage digital signals is determined as the first voltage digital signal, and the minimum voltage digital signal among the voltage digital signals is determined as the second voltage digital signal. The difference between the first voltage digital signal and the second voltage digital signal is then calculated to obtain the maximum difference between any two voltage digital signals of the electronic fuses.

[0146] Step 502: Determine a voltage digital signal average based on the voltage digital signals of the at least two electronic fuses.

[0147] Step 503: Determine the amplitude difference based on the difference and the mean value of the voltage digital signal.

[0148] Specifically, the amplitude difference can be determined based on the following formula :

[0149]

[0150] in, is the difference between the first voltage digital signal and the second voltage digital signal, is the mean value of the voltage digital signal.

[0151] The amplitude difference can characterize the distribution deviation of each phase voltage in the amplitude dimension.

[0152] Step 504 : determining a phase difference based on a maximum phase difference and a rated phase difference between the phases of the at least two voltage digital signals.

[0153] The voltage digital signals of the multi-phase electronic fuses can be synchronously sampled using an analog-to-digital converter. Fourier transform is then performed on the sampled data to extract the phase angle of the main frequency component of each phase voltage digital signal. The phase difference between each pair of voltage digital signals is then calculated, and the maximum phase difference is determined.

[0154] When power is supplied through a two-phase electronic fuse, the rated phase difference between the voltage digital signals of the two-phase electronic fuse is generally 90 degrees. When power is supplied through a three-phase electronic fuse, the rated phase difference between the voltage digital signals is generally 120 degrees.

[0155] Specifically, the phase difference can be determined based on the following formula :

[0156]

[0157] in, is the maximum phase difference, is the rated phase difference.

[0158] The phase difference can characterize the distribution deviation of each phase voltage in the phase dimension.

[0159] Step 505: Determine a comprehensive difference based on the amplitude difference and the phase difference.

[0160] Specifically, the comprehensive difference can be determined based on the following formula :

[0161]

[0162] in, is the amplitude difference, is the phase difference.

[0163] Step 506: If the comprehensive difference is greater than a preset threshold, it is determined that the target condition is met.

[0164] For example, the preset threshold is set to 20%. In a system powered by three-phase electronic fuses, the voltage digital signals of the three electronic fuses are obtained as 2000, 1900, and 1500, respectively. The first voltage digital signal is determined to be 2000, the second voltage digital signal is determined to be 1500, the difference between the first voltage digital signal and the second voltage digital signal is calculated to be 500, and the average of the voltage digital signals of the three electronic fuses is calculated to be 1800. The amplitude difference is determined to be approximately 28%. The maximum phase difference is obtained to be 15 degrees, and the rated phase difference is 120 degrees, so the phase difference is determined to be 12.5%. Based on the amplitude difference and the phase difference, the comprehensive difference is determined to be approximately 30.66%, which is greater than the preset threshold of 20%. Therefore, it is determined that the target condition is met.

[0165] In the above scheme, by integrating the differences in the two dimensions of voltage amplitude and phase difference into a comprehensive difference, the possible misjudgment or missed judgment problems of traditional single-dimensional criteria (such as only monitoring the amplitude difference) are avoided, and the accuracy and stability of determining whether there are two voltage digital signals that differ by at least one order of magnitude are further improved.

[0166] In an example of the present application, a data processing method is also provided, such as Figure 6 As shown, the determining that the target condition is met based on the voltage digital signals of the at least two electronic fuses includes:

[0167] Step 601: Determine a corresponding voltage digital signal vector based on the voltage digital signal.

[0168] The voltage digital signals of the multi-phase electronic fuses can be synchronously sampled using an analog-to-digital converter. The sampled data is then Fourier transformed to extract the phase angle of the primary frequency component of each phase voltage digital signal. The corresponding voltage digital signal vector is then determined based on the voltage digital signal and its phase angle.

[0169] Specifically, the voltage digital signal vector can be determined based on the following formula :

[0170]

[0171] in, is a voltage digital signal, is the phase angle of the voltage digital signal, is a unit vector.

[0172] Step 602: Determine the modulus of the sum of the voltage digital signal vectors of the at least two electronic fuses.

[0173] Specifically, the modulus of the sum of the voltage digital signal vectors of the at least two electronic fuses can be determined based on the following formula: :

[0174]

[0175] in, For the A voltage digital signal, For the The phase angle of the voltage digital signal, is a unit vector, is the number of electronic fuses.

[0176] Step 603: Determine a voltage digital signal average based on the voltage digital signals of the at least two electronic fuses.

[0177] Step 604: Determine a first ratio of the modulus value to the mean value of the voltage digital signal.

[0178] Specifically, the first ratio can be determined based on the following formula :

[0179]

[0180] in, is the modulus of the sum of the voltage digital signal vectors of all electronic fuses, is the mean value of the voltage digital signal.

[0181] Step 605: If the first ratio is greater than a preset threshold, it is determined that the target condition is met.

[0182] For example, the preset threshold is set to 20%. In a system powered by three-phase electronic fuses, the voltage digital signals of the three electronic fuses are 2000, 1900, and 1500, respectively, and the corresponding phase angles are 0 degrees, -120 degrees, and 120 degrees, respectively. Based on the voltage digital signals of the three electronic fuses and the corresponding phase angles, the voltage digital signal vectors of the three electronic fuses are determined to be 、 and Based on the voltage digital signal vectors of the three electronic fuses, the modulus of the sum of the voltage digital signal vectors is determined to be approximately 458.1. Based on the voltage digital signals of the three electronic fuses, the mean of the voltage digital signals is determined to be 1800. The first ratio is determined to be approximately 25.45%, which is greater than the preset threshold of 20%. Therefore, it is determined that the target condition is met.

[0183] In the above scheme, the voltage digital signal vectors of the electronic fuses are determined, followed by the modulus of the sum of the voltage digital signal vectors of all electronic fuses. A first ratio is then determined based on the modulus and the mean of the voltage digital signal vectors. Finally, the first ratio is compared with a preset threshold to determine whether the target condition is met. The vector sum modulus not only reflects the amplitude difference but also incorporates the influence of phase difference, reflecting differences in both amplitude and phase. The vector sum operation suppresses random noise interference and is more robust. This further improves the accuracy and stability of determining whether two voltage digital signals differ by at least one order of magnitude.

[0184] In an example of the present application, a data processing method is also provided, such as Figure 7 As shown, performing analog-to-digital conversion on the voltage analog signal to obtain a corresponding voltage digital signal includes:

[0185] Step 701: Acquire a reference voltage of an analog-to-digital converter.

[0186] In this embodiment, the reference voltage of the analog-to-digital converter is generally set to 2.5V or 3.3V. In other implementations, the reference voltage can be set based on specific requirements.

[0187] Step 702: Convert the voltage analog signal into a voltage digital signal based on the reference voltage.

[0188] The analog-to-digital converter converts a voltage analog signal into a voltage digital signal based on a reference voltage.

[0189] The conversion method is determined by the type of analog-to-digital converter. For example, an integrating analog-to-digital converter uses a reference voltage to measure the integration time of a voltage analog signal. The voltage analog signal is first converted into a time width by an integrator, and then compared with the integration time of the reference voltage. The time difference is recorded by a counter and output as a voltage digital signal. The analog-to-digital converter converts the difference between the voltage analog signal and the reference voltage into pulse density through a modulator, and then outputs a voltage digital signal through a digital filter.

[0190] In the above solution, the analog-to-digital converter converts the voltage analog signal into a voltage digital signal that can be processed by a computer through a reference voltage, so that it can be accurately determined whether there are two voltage digital signals that differ by at least one order of magnitude.

[0191] In an example of the present application, a data processing method is also provided, such as Figure 8 As shown, converting the voltage analog signal into a voltage digital signal based on the reference voltage includes:

[0192] Step 801: Determine a second ratio between the voltage analog signal and the reference voltage.

[0193] Specifically, the second ratio can be determined based on the following formula :

[0194]

[0195] in, is a voltage analog signal, is the reference voltage.

[0196] Step 802 : Determine a voltage digital signal corresponding to the voltage analog signal based on the second ratio and the correction value.

[0197] Specifically, the voltage digital signal can be determined based on the following formula :

[0198]

[0199] in, For the second ratio, is the correction value.

[0200] The correction value is determined based on the number of bits of the analog-to-digital converter. For example, the maximum range of a 12-bit analog-to-digital converter is , then the correction value is .

[0201] In the above solution, the voltage analog signal is divided by the reference voltage to obtain a second ratio, and then the second ratio is multiplied by the correction value to obtain the corresponding voltage digital signal. This achieves analog-to-digital conversion without the involvement of complex algorithms, significantly reducing the performance requirements of the hardware.

[0202] In an example of the present application, a data processing method is also provided, such as Figure 9 As shown, the determining that the target condition is met based on the voltage digital signals of the at least two electronic fuses includes:

[0203] Step 901: Acquire a reference voltage of an analog-to-digital converter.

[0204] In this embodiment, the reference voltage of the analog-to-digital converter is generally set to 2.5V or 3.3V. In other implementations, the reference voltage can be set based on specific requirements.

[0205] Step 902: Determine a third ratio between the overcurrent protection voltage and the reference voltage.

[0206] The third ratio can be determined based on the following formula :

[0207]

[0208] in, is the overcurrent protection voltage, is the reference voltage.

[0209] Step 903: Determine the preset voltage based on the third ratio and the correction value.

[0210] The preset voltage can be determined based on the following formula :

[0211]

[0212] in, For the third ratio, is the correction value.

[0213] Likewise, the correction value is determined based on the number of bits of the ADC. For example, the maximum range of a 12-bit ADC is , then the correction value is .

[0214] In the above solution, the overcurrent protection voltage is divided by the reference voltage to obtain a third ratio, which is then multiplied by a correction value to obtain the corresponding preset voltage. This achieves analog-to-digital conversion of the overcurrent protection voltage without the need for complex algorithms, significantly reducing hardware performance requirements. Furthermore, based on the determined preset voltage, it is then possible to accurately determine whether an electronic fuse exceeds the overcurrent protection voltage.

[0215] In an example of the present application, a data processing method is also provided, such as Figure 10 As shown, the method further includes:

[0216] Step 1001: Determine that the phases of the at least two electronic fuses are not current-balanced and overcurrent protection is triggered, and read the log data from the target storage area.

[0217] After determining that the electronic fuse triggers the overcurrent protection due to uneven current between phases, the log data is read from the target access area.

[0218] In this embodiment, if the log data is stored in a register or a firmware storage area, the log data may be read from the register or the firmware storage area via I2C (a type of bus).

[0219] Step 1002 : Determine a reliability coefficient based on a first voltage digital signal, where the log data also includes the first voltage digital signal.

[0220] In this embodiment, the log data also includes a first voltage digital signal.

[0221] The reliability coefficient is determined based on the first voltage digital signal. The reliability coefficient can be determined by the ratio of the first voltage digital signal to the preset voltage. For example, if the first voltage digital signal is 2400 and the preset voltage is 2000, the reliability coefficient is 1.2.

[0222] The reliability coefficient can also be determined by a preset mapping relationship. For example, if the first voltage digital signal is set to be within the range of 1000-2000, the corresponding reliability coefficient is 1.1, and if the first voltage digital signal is within the range of 2000-3000, the corresponding reliability coefficient is 1.2.

[0223] Step 1003: Adjust the preset voltage based on the reliability coefficient.

[0224] The reliability coefficient is multiplied by the preset voltage to obtain a new preset voltage, and the original preset voltage is adjusted.

[0225] In the above solution, after determining that overcurrent protection has been triggered due to uneven current flow between phases, the original overcurrent protection voltage is multiplied by a reliability coefficient to increase the protection voltage. This reduces global overcurrent protection activations caused by single-phase anomalies and significantly improves the stability of the power supply system. By introducing a reliability coefficient determined by the first voltage digital signal, the preset voltage can be adjusted in real time to dynamically adapt to load fluctuations. This avoids the inability of fixed thresholds to adapt to different operating conditions, further improving the robustness of the power supply system.

[0226] In an example of the present application, a data processing method is also provided, such as Figure 11 As shown, the method further includes:

[0227] Step 1101: Determine that the phases of the at least two electronic fuses are not current-balanced and overcurrent protection is triggered, and obtain resistance values ​​of the electronic fuses.

[0228] After determining that the electronic fuse has triggered overcurrent protection due to uneven current flow between phases, the resistance value of each electronic fuse is obtained. Typically, the resistance value of the electronic fuse is stored in a register, and the resistance value of each electronic fuse can be obtained from the register via I2C.

[0229] Step 1102: Determine the overcurrent protection voltage of the electronic fuse based on the resistance value and the overcurrent protection current.

[0230] The overcurrent protection voltage can be determined based on the following formula :

[0231]

[0232] in, is the overcurrent protection current of the electronic fuse, is the resistance value of the electronic fuse.

[0233] Step 1103: Convert the overcurrent protection voltage into a preset voltage of the electronic fuse.

[0234] For example, in a system powered by three-phase electronic fuses, the overcurrent protection currents of the three electronic fuses are 15A, 12A, and 18A, respectively, and the resistance values ​​are 0.05 ohms, 0.06 ohms, and 0.04 ohms. The overcurrent protection voltages of the three electronic fuses are determined to be 0.75V, 0.72V, and 0.72V, respectively. The overcurrent protection voltages are converted to preset voltages and set accordingly.

[0235] In the above solution, the overcurrent protection voltage of the electronic fuse is set by multiplying the overcurrent protection current and the resistance value of the electronic fuse. Based on the different resistance values ​​of the electronic fuses in each phase, the overcurrent protection voltage of the electronic fuse in each phase is precisely adapted, which can effectively avoid the problems of false triggering or protection failure caused by uneven current between phases.

[0236] In an example of the present application, a data processing method is also provided, such as Figure 12 As shown, after converting the overcurrent protection voltage into the preset voltage of the electronic fuse, the method further includes:

[0237] Step 1201: Read the log data from the target storage area.

[0238] After the product of the overcurrent protection current and the resistance value of the electronic fuse is set as the overcurrent protection voltage of the electronic fuse, the log data is read from the target access area.

[0239] Likewise, in this embodiment, if the log data is stored in a register or a firmware storage area, the log data can be read from the register or the firmware storage area via I2C.

[0240] Step 1202 : determining a corresponding adjustment coefficient based on a third voltage digital signal, wherein the log data further includes the third voltage digital signal, and the third voltage digital signal is a voltage digital signal greater than a preset voltage.

[0241] In this embodiment, the log data also includes a first voltage digital signal.

[0242] The third voltage digital signal is a voltage digital signal greater than a preset voltage, that is, a voltage digital signal of an electronic fuse whose voltage exceeds the overcurrent protection voltage. In a system powered by multi-phase electronic fuses, the voltage of multiple electronic fuses may exceed the overcurrent protection voltage.

[0243] The corresponding adjustment coefficient is determined based on the third voltage digital signal. The adjustment coefficient can be determined by the ratio of the third voltage digital signal to the preset voltage. For example, if the third voltage digital signal is 2200 and the preset voltage is 2000, the reliability coefficient is 1.1.

[0244] The adjustment coefficient can also be determined by a preset mapping relationship. For example, if the third voltage digital signal is set to be within the range of 1000-2000, the corresponding reliability coefficient is 1.1, and if the third voltage digital signal is within the range of 2000-3000, the corresponding reliability coefficient is 1.2.

[0245] Step 1203 : Adjust the preset voltage of the electronic fuse to which the third voltage digital signal belongs based on the adjustment coefficient.

[0246] It should be noted that the preset voltage of the third voltage digital signal, i.e., the voltage digital signal of an electronic fuse exceeding the overcurrent protection voltage, can be adjusted. The preset voltage of the voltage digital signal of an electronic fuse not exceeding the overcurrent protection voltage can also be adjusted. Similarly, a corresponding adjustment coefficient is determined based on the voltage digital signal, and then the preset voltage of the voltage digital signal is adjusted based on the adjustment coefficient. For example, if the voltage digital signal of an electronic fuse is 1800 and the preset voltage is 2000, and the voltage does not exceed the preset voltage, the adjustment coefficient is determined to be 0.9. Based on the adjustment coefficient and the preset voltage, a new preset voltage of 1800 is determined, and the original preset voltage is adjusted.

[0247] In the above-described scheme, after determining that overcurrent protection has been triggered due to uneven current flow between phases, the original overcurrent protection voltage is multiplied by an adjustment coefficient to increase the overcurrent protection voltage, thereby reducing global overcurrent protection activation due to single-phase anomalies and significantly improving the stability of the power supply system. By introducing an adjustment coefficient determined by a third voltage digital signal, the preset voltage can be adjusted in real time to dynamically adapt to load fluctuations. This avoids the situation where a fixed threshold cannot adapt to different operating conditions, further improving the robustness of the power supply system. Furthermore, the preset voltages of all electronic fuses, including those with voltages exceeding the preset voltage and those below the preset voltage, can be adjusted, so that the preset voltages at which each electronic fuse triggers overcurrent protection can be more closely aligned with actual operating conditions, further reducing the occurrence of global overcurrent protection activation due to single-phase anomalies and further improving the stability of the power supply system.

[0248] In an example of the present application, a data processing method is also provided, such as Figure 13 As shown, before adjusting the preset voltage, the method further includes:

[0249] Step 1301: Read historical log data from the target storage area.

[0250] Before adjusting the preset voltage, historical log data is read from the target access area.

[0251] In this embodiment, if the historical log data is stored in a register or a firmware storage area, the historical log data can be read from the register or the firmware storage area via I2C.

[0252] Step 1302: If it is determined that the fault identifier indicates that the at least two electronic fuses have uneven current distribution between phases and the number of historical log data that trigger overcurrent protection is greater than a preset number, the preset voltage is adjusted.

[0253] In this embodiment, the preset number can be set based on the number of historical log data. For example, if there are 100 historical log data, the preset number can be set to 80.

[0254] In the above solution, the number of historical log data points that triggered overcurrent protection due to uneven current between phases determines whether to adjust the preset voltage. This can identify the frequency of abnormal operating conditions and adjust the preset voltage only when the number of events exceeds a preset number. This further improves the stability of the power supply system.
