Description

Technical Field

[0001] The present application relates to the technical field of drive power supply testing, and in particular to a drive power supply testing method, device, equipment and storage medium. Background Art

[0002] The driver power supply is an indispensable component of electronic devices. With the rapid development of applications such as 3D printers, LED lighting and lasers, the performance requirements of the driver power supply are getting higher and higher. The quality of its performance directly affects the working stability and reliability of electronic equipment. Therefore, it is very necessary to perform performance testing on the driver power supply to ensure its quality.

[0003] In the prior art, an oscilloscope is usually used to measure the input voltage, input current, output voltage, output current and other parameters of the driving power supply under specific load conditions, and then the conversion efficiency of the load point is calculated, and its accuracy is judged by observing the waveform of the output voltage. However, this method can only obtain the performance indicators of the driving power supply under a single working condition, and cannot reflect the various load changes it faces in actual applications. When the electronic equipment is actually working, its load often changes dynamically, and the driving power supply needs to maintain good working performance under different load conditions. Therefore, the above test method is difficult to fully evaluate the comprehensive performance of the driving power supply. Summary of the invention

[0004] The present application provides a driving power supply testing method, device, equipment and storage medium for accurately evaluating the comprehensive performance of the driving power supply.

[0005] In a first aspect, the present application provides a driving power supply testing method, the method comprising: obtaining the input voltage, input current, output voltage and output current of the driving power supply to be tested under different loads; calculating the conversion efficiency of the driving power supply to be tested under different loads according to the input voltage, input current, output voltage and output current of the driving power supply to be tested under different loads; determining the stability parameters of the power supply to be tested according to the conversion efficiency of the driving power supply to be tested under different loads; obtaining the output voltage fluctuation range of the driving power supply to be tested under different loads, and determining the precision parameters of the driving power supply to be tested according to the output voltage fluctuation range of the driving power supply under different loads; and determining the working performance level of the driving power supply to be tested in combination with the stability parameters and the precision parameters.

[0006] By adopting the above technical solution, the voltage and current data of the tested driving power supply under different loads are obtained, the conversion efficiency is calculated and the stability parameters are determined, and the output voltage fluctuation range is analyzed to determine the precision parameters. Finally, the working performance level is determined by combining these two parameters, thereby achieving a comprehensive and objective evaluation of the driving power supply performance. This method not only considers the performance of the driving power supply under various load conditions, but also takes into account the two key dimensions of efficiency stability and output accuracy, thereby providing a unified and comparable performance evaluation standard. Through this comprehensive evaluation, the comprehensive performance of the driving power supply can be accurately evaluated.

[0007] Optionally, the conversion efficiency of the driving power supply to be tested under different loads is calculated according to the input voltage, the input current, the output voltage and the output current of the driving power supply to be tested under different loads, including: calculating the input power of the driving power supply to be tested under different loads according to the input voltage and the input current of the driving power supply to be tested under different loads; the input power is equal to the product of the input voltage and the input current; calculating the output power of the driving power supply to be tested under different loads according to the output voltage and the output current of the driving power supply to be tested under different loads; the output power is equal to the product of the output voltage and the output current; calculating the conversion efficiency of the driving power supply to be tested under different loads according to the input power and the output power of the driving power supply to be tested under different loads; the conversion efficiency is equal to the output power divided by the input power.

[0008] By adopting the above technical solution, the accuracy and reliability of the conversion efficiency calculation are ensured by calculating the input power and output power separately. The calculation of input power takes into account the product of input voltage and input current, while the output power is based on the product of output voltage and output current. This method fully reflects the energy conversion process of the driving power supply. Secondly, by performing these calculations under different load conditions, the scheme can capture the performance changes of the driving power supply under various working conditions and provide a more comprehensive efficiency evaluation. Finally, by calculating the conversion efficiency by dividing the output power by the input power, the scheme establishes a standardized efficiency index, which is convenient for horizontal comparison between different driving power supplies. This accurate and comprehensive conversion efficiency calculation method not only improves the accuracy of the driving power supply performance evaluation, but also lays a solid foundation for the subsequent determination of stable parameters.

[0009] Optionally, determining the stability parameters of the power supply to be tested based on the conversion efficiency of the power supply to be tested under different loads includes: obtaining a first conversion efficiency of the power supply to be tested under a maximum load and a second conversion efficiency of the power supply to be tested under a minimum load; calculating a difference between the first conversion efficiency and the second conversion efficiency; comparing the difference with a set threshold; if the difference is not greater than the set threshold, determining that the stability parameters of the power supply to be tested are a first preset value; if the difference is greater than the set threshold, determining that the stability parameters of the power supply to be tested are a second preset value; wherein, the first preset value is greater than the second preset value.

[0010] By adopting the above technical solution, an accurate evaluation of the stability of the driving power supply is achieved by comparing the difference in conversion efficiency of the driving power supply to be tested under maximum load and minimum load. By obtaining the first conversion efficiency under maximum load and the second conversion efficiency under minimum load, calculating their difference, and comparing them with the set threshold, the scheme establishes an objective stability judgment standard. When the difference is not greater than the set threshold, the stability parameter is determined to be a higher first preset value, indicating that the driving power supply maintains good efficiency stability under different load conditions; when the difference is greater than the set threshold, the stability parameter is determined to be a lower second preset value, indicating that the efficiency of the driving power supply varies greatly with the load. This method can not only quantify the stability performance of the driving power supply, but also flexibly adjust the set threshold according to actual application needs to meet the requirements of different scenarios.

[0011] Optionally, determining the precision parameters of the driving power supply to be tested according to the output voltage fluctuation range of the driving power supply under different loads includes: obtaining the output voltage fluctuation upper limit value and the output voltage fluctuation lower limit value of the driving power supply to be tested under different loads; calculating the first deviation between the output voltage fluctuation upper limit value and the nominal output voltage under different loads, and the second deviation between the output voltage fluctuation lower limit value and the nominal output voltage; taking the maximum value of the first deviation between the output voltage fluctuation upper limit value and the nominal output voltage under different loads as the maximum voltage deviation, and the absolute value of the maximum value of the second deviation between the output voltage fluctuation lower limit value and the nominal output voltage as the absolute value of the maximum voltage deviation; if both the maximum voltage deviation and the absolute value of the maximum voltage deviation are not greater than the set precision threshold value, determining the precision parameters of the driving power supply to be tested as the first preset parameters; if the maximum voltage deviation and / or the absolute value of the maximum voltage deviation are greater than the set precision threshold value, determining the precision parameters of the driving power supply to be tested as the second preset parameters; wherein, the first preset parameter is greater than the second preset parameter.

[0012] By adopting the above technical solution, a comprehensive evaluation of the precision of the tested drive power supply is achieved by analyzing the output voltage fluctuation of the tested drive power supply under different loads in detail. By obtaining the upper and lower limits of the output voltage fluctuation and calculating their deviations from the nominal output voltage, an accurate voltage stability evaluation system is established. By determining the maximum voltage deviation and its absolute value and comparing it with the set precision threshold, the output accuracy of the drive power supply can be objectively judged. When the maximum voltage deviation and its absolute value do not exceed the set precision threshold, the precision parameter is determined to be a higher first preset parameter, indicating that the drive power supply has excellent output stability; otherwise, it is determined to be a lower second preset parameter, indicating that there is room for improvement. This method not only considers the positive and negative directions of voltage fluctuations, but also covers the performance under different load conditions, providing a comprehensive and accurate precision evaluation. Through this standardized evaluation method, users can better select drive power supplies that meet specific application requirements, and designers can also get clear optimization directions. In addition, the flexibility of this evaluation method allows the adjustment of the set precision threshold to adapt to the needs of different application scenarios, which helps to promote the development of drive power supply technology to higher precision and ultimately improve the performance and reliability of the entire electronic system.

[0013] Optionally, the combination of the stability parameter and the precision parameter to determine the working performance level of the driving power supply to be tested includes: performing weighted calculation on the stability parameter and the precision parameter to obtain a comprehensive performance value; comparing the comprehensive performance value with a preset performance standard value; if the comprehensive performance value is not less than the preset performance standard value, determining that the working performance level of the driving power supply to be tested is qualified; if the comprehensive performance value is less than the preset performance standard value, determining that the working performance level of the driving power supply to be tested is unqualified.

[0014] By adopting the above technical solution, the comprehensive performance value is obtained by combining the stability parameters and the precision parameters for weighted calculation, and compared with the preset performance standard value, a comprehensive evaluation of the working performance of the driver power supply to be tested is achieved. This method organically combines the two key indicators of efficiency stability and output accuracy of the driver power supply, providing a more comprehensive and objective performance evaluation standard. Through weighted calculation, the importance of different parameters can be flexibly adjusted to meet the needs of different application scenarios. The comprehensive performance value is compared with the preset performance standard value, and the working performance level is determined as qualified or unqualified based on this, providing users with an intuitive and clear evaluation result. This evaluation method not only simplifies the selection process of the driver power supply, but also provides producers with a clear direction for improvement.

[0015] Optionally, after determining the working performance level of the driving power supply to be tested, it also includes: if the working performance level of the driving power supply to be tested is qualified, a test pass report is generated, and the test pass report includes the model of the driving power supply to be tested, the stability parameters, the precision parameters and the working performance level; if the working performance level of the driving power supply to be tested is unqualified, a test fail report is generated, and the test fail report includes the model of the driving power supply to be tested, the stability parameters, the precision parameters, the working performance level and the reason for failing the test.

[0016] By adopting the above technical solution and generating detailed test reports, systematic recording and feedback of the performance evaluation results of the driver power supply to be tested are achieved. For drivers with qualified working performance levels, the generated test pass report contains the model, stability parameters, precision parameters and working performance level, providing users with comprehensive performance information for easy selection and application. For unqualified drivers, the test failure report not only contains the above information, but also adds the reasons for failure to pass the test, providing manufacturers and designers with clear improvement directions. This differentiated reporting mechanism can not only meet the needs of quality control, but also promote continuous product optimization. Through standardized report formats, the solution improves the readability and comparability of test results, and helps to establish unified industry evaluation standards.

[0017] Optionally, after determining the working performance level of the driving power supply to be tested, it also includes: receiving a driving power supply screening request submitted by a user, the driving power supply screening request including working environment parameters; and screening a target driving power supply that matches the working environment parameters from a driving power supply database based on the working environment parameters.

[0018] By adopting the above technical solution, an intelligent and personalized drive power selection mechanism is realized by receiving the drive power screening request submitted by the user and screening the matching target drive power from the drive power database according to the working environment parameters contained therein. This method accurately matches the specific needs of the user with the performance characteristics of the drive power, improving the pertinence and applicability of the drive power selection. By considering the working environment parameters, the solution can more comprehensively evaluate the performance of the drive power in actual application scenarios, avoiding the deviation that may be caused by relying solely on general performance indicators. This not only simplifies the user's selection process and reduces the risk of selection errors, but also improves the efficiency and reliability of the entire system.

[0021] In a fourth aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution: storing a computer program that can be loaded by a processor and execute any of the above-mentioned driving power supply testing methods.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: By obtaining the voltage and current data of the driver under different loads, calculating the conversion efficiency and determining the stability parameters, and analyzing the output voltage fluctuation range to determine the precision parameters, and finally combining these two parameters to determine the working performance level, a comprehensive and objective evaluation of the driver performance is achieved.

[0025] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0026] In the description of the embodiments of the present application, words such as "illustrative", "for example" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "illustrative", "for example" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "illustrative", "for example" or "for example" is intended to present related concepts in a concrete way.

[0027] Figure 1 1 is a flow chart of a driving power supply testing method provided in an embodiment of the present application. Figure 1 As shown, the method includes S101-S105: S101, obtaining the input voltage, input current, output voltage and output current of the driving power supply to be tested under different loads.

[0028] In this embodiment, it is first necessary to obtain the input voltage, input current, output voltage and output current of the driver power supply under different loads. This step is the basis of the entire test method, and its purpose is to comprehensively collect the key electrical parameters of the driver power supply under various working conditions to provide necessary data support for subsequent performance evaluation.

[0029] In specific implementation, an automated test system can be used, which includes a programmable electronic load, a high-precision voltmeter and an ammeter. During the test, the drive power supply to be tested is connected to the test system, and then the electronic load is controlled by programming to gradually change within a preset load range.

[0030] For the driver power supply of 3D printers, LEDs or lasers, it is usually necessary to cover multiple load points from no load to full load. For example, 0%, 25%, 50%, 75% and 100% rated load can be selected as test points. At each load point, use a high-precision voltmeter and ammeter to measure and record the voltage and current values ​​at the input and output of the driver power supply respectively.

[0031] In order to ensure the accuracy and reliability of the test data, a certain stabilization time should be maintained at each load point, usually 5-10 minutes, so that the drive power supply can reach a stable working state. At the same time, in order to reduce the impact of random errors, multiple measurements can be made at each load point and the average value can be taken. In addition, considering the high requirements of 3D printers, LEDs and lasers for power supply stability, the accuracy of the measuring equipment should reach 0.1% or higher.

[0032] This comprehensive data collection method can effectively capture the performance characteristics of the driver under different working conditions. By obtaining the input and output parameters under different loads, the load adaptability, efficiency change trend and output stability of the driver can be fully reflected. These data provide a solid foundation for the subsequent calculation of conversion efficiency, evaluation of stability and precision.

[0033] S102, calculating the conversion efficiency of the driving power supply under different loads according to the input voltage, input current, output voltage and output current of the driving power supply under different loads.

[0034] In one example, the input power and output power of the driver under test at each load point are calculated. The input power is equal to the product of the input voltage and the input current, and the output power is equal to the product of the output voltage and the output current. Then, the conversion efficiency of each load point is obtained by dividing the output power by the input power.

[0035] This calculation method can intuitively reflect the energy conversion capability of the driver under different load conditions. By calculating the conversion efficiency under different loads, the efficiency-load curve can be drawn to identify the optimal operating point of the driver, that is, the load range with the highest efficiency. For example, for 3D printers, the printing strategy can be adjusted based on this information to make the driver work in the high-efficiency range as much as possible; for LED and laser applications, the most appropriate operating current can be selected accordingly to maximize energy efficiency while ensuring performance.

[0036] In general, calculating the conversion efficiency under different loads not only provides a key indicator for evaluating the performance of the driver, but also lays the foundation for subsequent stability analysis and comprehensive performance evaluation.

[0037] Based on the above embodiment, as an optional implementation, in S102, according to the input voltage, input current, output voltage and output current of the drive power supply under different loads, calculating the conversion efficiency of the drive power supply under different loads specifically includes S201-S203: S201, calculating the input power of the driving power supply under different loads according to the input voltage and input current of the driving power supply under different loads; the input power is equal to the product of the input voltage and the input current.

[0038] S202, calculating the output power of the driving power supply under different loads according to the output voltage and output current of the driving power supply under different loads; the output power is equal to the product of the output voltage and the output current.

[0039] S203, calculating the conversion efficiency of the driving power supply under different loads according to the input power and output power of the driving power supply under different loads; the conversion efficiency is equal to the output power divided by the input power.

[0040] In an example, the calculation formula of input power is: input power=input voltage×input current, and the calculation formula of output power is: output power=output voltage×output current.

[0041] Measure the input voltage, input current, output voltage and output current of the driver under different load conditions (such as 10%, 25%, 50%, 75% and 100% rated load). Then, use the above formula to calculate the input power, output power and conversion efficiency of each load point respectively. These calculations can be automatically completed by spreadsheet software or specialized test software to ensure the accuracy and efficiency of the calculations.

[0042] Secondly, by analyzing the conversion efficiency under different loads, an efficiency-load curve can be drawn. This curve can intuitively show the efficiency changes of the driver power supply over the entire operating range, which helps to identify the optimal operating point and potential problem areas. For example, if it is found that the efficiency drops significantly within a certain load range, this may indicate a problem in the design or component, which requires further investigation and optimization.

[0043] In addition, this approach provides an objective basis for comparing the performance of different drivers. Efficiency data and curves can be used to make more informed decisions when selecting a driver for a specific application. For example, for a 3D printer that needs to operate over a wide load range, a driver that maintains high efficiency over the entire load range may be selected.

[0044] S103, determining the stability parameters of the power supply to be tested according to the conversion efficiency of the driving power supply to be tested under different loads.

[0045] In one example, the method for determining the stability parameter is by analyzing the change of conversion efficiency under different loads. Specifically, the difference between the highest conversion efficiency and the lowest conversion efficiency is calculated, and this difference is defined as the stability parameter. The calculation formula can be expressed as: stability parameter = highest conversion efficiency - lowest conversion efficiency. The degree of fluctuation of conversion efficiency can reflect the stability of the driving power supply under different load conditions. A smaller stability parameter means that the driving power supply can maintain relatively stable performance under various load conditions.

[0046] In actual operation, the highest and lowest values ​​are found from the conversion efficiencies of each load point calculated in step S102. Then, these two values ​​are substituted into the above formula to obtain the stability parameter. The actual operating range of the device should be considered during the calculation.

[0047] Based on the above embodiment, as an optional implementation, in S103, according to the conversion efficiency of the driving power supply to be tested under different loads, determining the stability parameters of the power supply to be tested specifically includes S301-S305: S301, obtaining a first conversion efficiency of the driving power supply under a maximum load and a second conversion efficiency of the driving power supply under a minimum load.

[0048] In one example, the maximum and minimum load conditions of the driver to be tested need to be determined. Typically, the maximum load corresponds to the rated power of the driver, while the minimum load may be 10% of the rated power or less, depending on the actual operating range of the device. Under these two extreme load conditions, we measure the input voltage, input current, output voltage, and output current, respectively.

[0049] Then, using the calculation method in the previous step, the first conversion efficiency under maximum load and the second conversion efficiency under minimum load can be obtained. The specific calculation formula is: first conversion efficiency = (output power under maximum load / input power under maximum load) × 100%; second conversion efficiency = (output power under minimum load / input power under minimum load) × 100%.

[0050] The overall performance of the driver is evaluated by comparing the efficiency under extreme working conditions. The efficiency under maximum load reflects the energy conversion capability of the driver when working at full load, while the efficiency under minimum load reflects the performance of the driver under light load conditions. These two data points together constitute the two extremes of the driver efficiency curve, providing an important reference for subsequent stability analysis.

[0051] S302, calculating the difference between the first conversion efficiency and the second conversion efficiency.

[0052] S303, comparing the difference with a set threshold.

[0053] S304: If the difference is not greater than the set threshold, determine that the stability parameter of the driving power supply to be tested is a first preset value.

[0054] S305, if the difference is greater than the set threshold, determine that the stability parameter of the driving power supply to be tested is a second preset value; wherein the first preset value is greater than the second preset value.

[0055] In one example, the first preset value is a relatively high value, indicating that the driving power supply has good stability. When the difference in conversion efficiency under the maximum load and the minimum load is not greater than a set threshold, the driving power supply is considered stable, and thus is assigned the relatively high preset value.

[0056] The second preset value is a lower value, which indicates that the stability of the driving power supply is relatively poor. When the difference between the conversion efficiency under the maximum load and the minimum load is greater than the set threshold, the driving power supply is considered to be not stable enough, and thus is assigned this lower preset value.

[0057] The specific values ​​of the two preset values ​​may vary according to application requirements and industry standards. For example, possible settings are: first preset value: 90, second preset value: 60.

[0058] First, the difference between the first conversion efficiency and the second conversion efficiency is calculated. Then, the difference is compared with a pre-set threshold. The setting of this threshold needs to be determined according to the requirements of the specific application and industry standards, for example, it may be set to 5% or 10%.

[0059] If the difference is not greater than the set threshold value (step S304), the stability parameter of the driving power supply to be tested is determined to be the first preset value. This indicates that the efficiency difference between the driving power supply under the maximum load and the minimum load is small, and it has good stability. On the contrary, if the difference is greater than the set threshold value (step S305), the stability parameter of the driving power supply to be tested is determined to be the second preset value. In this case, the efficiency of the driving power supply under different load conditions fluctuates greatly, and the stability is relatively poor.

[0060] S104, obtaining the output voltage fluctuation range of the driving power supply to be tested under different loads, and determining the precise parameters of the driving power supply to be tested according to the output voltage fluctuation range of the driving power supply under different loads.

[0061] In one example, the output voltage fluctuation range of the driver at each load point is measured. This can be achieved by using a high-precision oscilloscope or data acquisition system. At each load point, the maximum and minimum values ​​of the output voltage are recorded over a certain period of time (usually a few minutes). The output voltage fluctuation range is the difference between the maximum and minimum values.

[0062] After obtaining the output voltage fluctuation range, the precision parameter can be calculated. The precision parameter is defined as the maximum output voltage fluctuation range among all load points, that is, precision parameter = max (output voltage fluctuation range of each load point).

[0063] The degree of fluctuation of the output voltage directly reflects the precision control capability of the driver. Smaller precision parameters mean that the driver can maintain a stable and accurate output under various load conditions.

[0064] In actual operation, the actual operating range of the device needs to be considered. For example, for a 3D printer, you may be more concerned about the output voltage fluctuation in the medium and high load range (such as 50% to 100%); while for LEDs or lasers, you may need to consider a wider load range because these devices may operate at different power levels.

[0065] Based on the above embodiment, as an optional implementation, in S104, according to the output voltage fluctuation range of the driving power supply under different loads, determining the precise parameters of the driving power supply to be tested specifically includes S401-S405: S401, obtaining an output voltage fluctuation upper limit value and an output voltage fluctuation lower limit value of the driving power supply to be tested under different loads.

[0066] S402, calculating a first deviation between an upper limit value of output voltage fluctuation and a nominal output voltage under different loads, and a second deviation between a lower limit value of output voltage fluctuation and the nominal output voltage.

[0067] S403, taking the maximum value of the first deviation between the output voltage fluctuation upper limit value and the nominal output voltage under different loads as the maximum voltage deviation, and the absolute value of the maximum value of the second deviation between the output voltage fluctuation lower limit value and the nominal output voltage as the absolute value of the maximum voltage deviation.

[0068] S404: If both the maximum voltage deviation and the absolute value of the maximum voltage deviation are not greater than the set precision threshold, determining that the precision parameter of the driving power supply to be tested is a first preset parameter.

[0069] S405, if the maximum voltage deviation and / or the absolute value of the maximum voltage deviation is greater than the set precision threshold, determine that the precision parameter of the driving power supply to be tested is a second preset parameter; wherein the first preset parameter is greater than the second preset parameter.

[0070] In one example, first, the output voltage data of the driver under test under different load conditions needs to be obtained. Based on this data, the maximum voltage deviation and the minimum voltage deviation can be calculated. The maximum voltage deviation refers to the maximum positive deviation between the actual output voltage and the rated output voltage, while the minimum voltage deviation is the maximum negative deviation. Then, the absolute values ​​of these two deviations are compared with the pre-set precision thresholds.

[0071] If the absolute values ​​of the maximum voltage deviation and the minimum voltage deviation are not greater than the set precision threshold, the precision parameter of the driving power supply to be tested is determined to be the first preset parameter. This indicates that the driving power supply can maintain a stable output voltage under various load conditions and has good precision. On the contrary, if the absolute value of the maximum voltage deviation and / or the minimum voltage deviation is greater than the set precision threshold, the precision parameter of the driving power supply to be tested is determined to be the second preset parameter. In this case, the output voltage of the driving power supply fluctuates greatly and the precision is relatively poor.

[0072] The first preset parameter and the second preset parameter are two reference values ​​used to quantify the precision of the driving power supply. The first preset parameter is a higher value, which means that the driving power supply has good precision. When the voltage deviation is within the allowable range, the driving power supply is assigned this higher preset parameter. The second preset parameter is a lower value, which means that the precision of the driving power supply is relatively poor. When the voltage deviation exceeds the allowable range, the driving power supply is assigned this lower preset parameter.

[0073] S105, determining the working performance level of the driving power supply to be tested by combining the stability parameter and the precision parameter.

[0074] In one example, the method for determining the working performance level is to weight the stability parameter and the precision parameter to obtain a comprehensive score. Specifically, the following formula can be used: comprehensive score = a × stability parameter + b × precision parameter, where a and b are weight coefficients that can be adjusted according to the needs of specific applications.

[0075] After obtaining the comprehensive score, the working performance level can be determined according to the preset score range. For example, the following grading can be set: Grade A: comprehensive score <5, Grade B: 5≤comprehensive score <10, Grade C: 10≤comprehensive score <15, Grade D: comprehensive score ≥15. The overall performance of the driver is evaluated by comprehensively considering stability and precision. A lower comprehensive score means that the driver performs well in both stability and precision control and is suitable for high-demand application scenarios.

[0076] Based on the above embodiment, as an optional implementation, in S105, combining the stability parameter and the precision parameter to determine the working performance level of the driving power supply to be tested specifically includes S501-S504: S501, performing weighted calculation on the stability parameter and the precision parameter to obtain a comprehensive performance value.

[0077] In one example, it is necessary to determine the weights of stability parameters and precision parameters. The setting of these weights depends on the needs and importance of the specific application. For example, for some applications, stability may be more important than precision, so the weight of the stability parameter may be higher. Suppose the weight of the stability parameter is set to 0.6 and the weight of the precision parameter is set to 0.4.

[0078] Then, the comprehensive performance value is calculated using the following formula: Comprehensive performance value = (stability parameter × 0.6) + (precision parameter × 0.4). The two key performance indicators are combined according to their relative importance to obtain a single value that can fully reflect the performance of the driver. This method takes into account the different requirements of stability and precision in different applications, and the weights can be adjusted according to the specific situation.

[0079] S502, comparing the comprehensive performance value with the preset performance standard value.

[0080] S503, if the comprehensive performance value is not less than the preset performance standard value, it is determined that the working performance level of the driving power supply to be tested is qualified.

[0081] If the comprehensive performance value is less than the preset performance standard value at S504, it is determined that the working performance level of the driving power supply to be tested is unqualified.

[0082] After determining the working performance level of the driver power supply to be tested, it also includes: If the working performance level of the driving power supply to be tested is qualified, a test pass report is generated, which includes the model, stability parameters, precision parameters and working performance level of the driving power supply to be tested; if the working performance level of the driving power supply to be tested is unqualified, a test fail report is generated, which includes the model, stability parameters, precision parameters, working performance level and the reason for failure of the test of the driving power supply to be tested.

[0083] In one example, a test pass report is generated for a driver with a qualified working performance level. This report contains key information about the driver, including model, stability parameters, precision parameters, and working performance level. This information fully reflects the performance characteristics of the driver and provides detailed performance data for users and manufacturers. For example, a test pass report may contain the following information: model XYZ-100, stability parameters 85, precision parameters 90, working performance level A (qualified).

[0084] For drivers with unqualified performance levels, a test failure report is generated. In addition to containing the same basic information as the pass report (model, stability parameters, precision parameters, and performance level), this report also contains the reasons for failure. This additional information is critical for identifying problems and guiding improvements. For example, a test failure report may contain the following information: Model ABC-200, stability parameters 60, precision parameters 55, performance level C (unqualified), reason for failure: the difference in conversion efficiency at maximum load and minimum load is too large, and the output voltage fluctuation exceeds the allowable range.

[0085] It is necessary to collect all relevant data obtained during the evaluation process, including stability parameters, precision parameters and comprehensive performance values. Then, determine the working performance level according to the preset standards. If the performance level is qualified, directly fill in the relevant information into the test pass report template. If the performance level is unqualified, further analyze the specific reasons for the unqualified, and fill this information together with other data into the test unqualified report template.

[0086] After determining the working performance level of the driver power supply to be tested, it also includes: A driving power source screening request submitted by a user is received, wherein the driving power source screening request includes a working environment parameter; and a target driving power source matching the working environment parameter is screened from a driving power source database according to the working environment parameter.

[0087] In one example, a driver database is established, which contains detailed information of all tested and rated drivers, including model, stability parameters, precision parameters, operating performance level and applicable working environment parameters. This database is the basis for accurate screening.

[0088] When a user submits a driver power screening request, the system will receive a request containing working environment parameters. These working environment parameters may include but are not limited to: working temperature range, humidity requirements, altitude, expected load variation range, electromagnetic compatibility requirements, etc. These parameters reflect the user's specific application scenarios and needs.

[0089] Next, the system will filter from the driver database based on the operating environment parameters provided by the user. The screening process uses a preset matching algorithm that takes into account the importance and interrelationship of various operating environment parameters. For example, for 3D printer applications, the system may pay more attention to temperature stability and load change adaptability; while for LED lighting applications, the system may pay more attention to electromagnetic compatibility and precise control of output voltage.

[0090] The screening process not only considers the matching degree of the working environment parameters, but also combines the previously determined working performance level. The system will give priority to recommending drivers that meet the working environment requirements and have a higher working performance level. This ensures that the selected target driver is not only suitable for the user's specific application scenario, but also provides excellent performance.

[0091] After the screening is completed, the system will generate a list of target drive power supplies, sorted from high to low according to the matching degree. The information of each target drive power supply includes model, stability parameters, precision parameters, working performance level, and description of the matching degree with user needs. This list provides users with a comprehensive and detailed basis for selection.
