Description

Technical Field

[0001] This invention relates to the field of regulation and control technology, and in particular to a voltage control method and system for electrical equipment. Background Technology

[0002] Existing voltage control systems utilize multiple voltage conversion units in conjunction with a voltage monitoring module to sample and compare each output voltage, and adjust the output of each conversion unit according to the differences to achieve coordinated control of multi-channel voltages. Alternatively, they can obtain feedback voltage through voltage division sampling, compare it with a reference voltage and a periodic carrier signal, generate PWM pulses to drive switching devices, and thereby regulate the load voltage to achieve voltage control.

[0003] For example, the voltage control system disclosed in Chinese invention patent CN107436614B includes: a first voltage conversion unit, a second voltage conversion unit, and a voltage monitoring module. The first voltage conversion unit is coupled to a first power supply and is used to output the first electrical energy provided by the first power supply at a first output voltage. The second voltage conversion unit is coupled to a second power supply and is used to output the second electrical energy provided by the second power supply at a second output voltage. The voltage monitoring module is electrically connected to the first voltage conversion unit and the second voltage conversion unit. The voltage monitoring module is used to control the first voltage conversion unit and the second voltage conversion unit based on the first output voltage and the second output voltage, so as to adjust the first output voltage or the second output voltage.

[0004] For example, the voltage control method disclosed in Chinese invention patent CN105094194B includes: dividing the load voltage across a load to generate a feedback voltage, and capturing the absolute value of a periodic triangular wave signal to generate a positive feedback signal. Then, the positive feedback signal is added to the feedback voltage to generate a sum signal, which is compared to a target voltage. If the sum signal is less than the target voltage, the load voltage is updated using an input voltage. Alternatively, the sum of the feedback voltage and the periodic triangular wave signal is compared to the target voltage, and the feedback voltage is compared to the target voltage. If both the sum and the feedback voltage are less than the target voltage, the load voltage is updated using an input voltage.

[0005] However, in the process of implementing the inventive technical solution in the embodiments of this application, it was found that the above-mentioned technology has at least the following technical problems:

[0006] In existing technologies, multiple electrical devices are connected to the same power supply. When the state of one electrical device changes abruptly (such as a voltage increase), it will affect the stable operation of other electrical devices under the same power supply. However, the stable operation of electrical devices has a significant impact on their state. Therefore, maintaining stable voltage for electrical devices is crucial. However, existing voltage control methods mostly use fixed parameters or simple feedback regulation. When the operating state of a single device changes abruptly, it is difficult to suppress voltage changes in a timely and accurate manner. Moreover, the impact can easily be transmitted to other devices under the same power supply channel, causing multiple electrical devices to experience operational fluctuations simultaneously. Therefore, there is a problem of severe fluctuations in related electrical devices due to untimely voltage control caused by abrupt changes in the operating state of electrical devices. Summary of the Invention

[0007] To address the technical problem in existing technologies where sudden changes in the operating state of the target electrical appliance lead to drastic fluctuations in the voltage of the target electrical appliance and related electrical appliances, embodiments of the present invention provide a voltage control method and system for electrical equipment. The technical solution is as follows:

[0008] On the one hand, a voltage control method for electrical equipment is provided, comprising: S1, when the central controller receives a voltage increase signal from an electrical appliance, marking the electrical appliance as a target electrical appliance, acquiring the target power output and the stable operating parameters of the target power channel, analyzing the initial soft-start capacitor value of the voltage regulator, and using the stable operating parameters to reflect the stability capability of the target power channel; S2, conducting a trial run test of the target electrical appliance based on the initial soft-start capacitor value to obtain the operating quality value of the target electrical appliance, and then processing it to obtain the trial run quality judgment result. If the trial run quality judgment result is qualified, the initial soft-start capacitor value is used to determine the voltage control capability of the target electrical appliance. If the dynamic capacitor value remains unchanged, otherwise execute S3. The target appliance's operating quality value is used to reflect the stability of the target appliance's operation. S3: Obtain the voltage regulator's ripple frequency, adjust the corresponding loop bandwidth, and analyze again to obtain the target appliance's second operating quality value. Then process the result to obtain the initial adjustment quality difference judgment, and perform the corresponding voltage regulator's secondary adjustment. S4: After receiving the voltage regulator's secondary adjustment signal, the central controller performs trial operation tests on each associated appliance to obtain the operating quality value of each associated appliance. Then process the result to obtain the fluctuation judgment of each associated appliance, and perform the corresponding voltage regulator's PWM duty cycle increase step adjustment.

[0009] On the other hand, a voltage control system for electrical equipment is provided. This system includes: a voltage regulator initial adjustment module, a target appliance trial operation module, a voltage regulator secondary adjustment module, and a correlation adjustment module. The voltage regulator initial adjustment module is used to mark the appliance as a target appliance after the central controller receives a voltage increase signal, acquire the target execution power and the stable operation parameters of the target power channel, and analyze the initial adjustment soft-start capacitor value of the voltage regulator. The target appliance trial operation module is used to perform trial operation testing of the target appliance based on the initial adjustment soft-start capacitor value, obtain the target appliance's operating quality value, and then process it to obtain the trial operation quality judgment result. If the trial operation... If the operational quality assessment result is qualified, the operation is maintained at the initial soft-start capacitor value; otherwise, the voltage regulator secondary adjustment module is executed. The voltage regulator secondary adjustment module is used to obtain the voltage regulator's ripple frequency, perform corresponding loop bandwidth adjustment, and analyze again to obtain the second operational quality value of the target electrical appliance. Then, it processes the result of the initial quality difference assessment and performs the corresponding voltage regulator secondary adjustment. The associated adjustment module is used by the central controller to perform trial operation tests on each associated electrical appliance after receiving the voltage regulator secondary adjustment signal, obtain the operational quality value of each associated electrical appliance, process the result of the fluctuation assessment of each associated electrical appliance, and then adjust the voltage regulator's PWM duty cycle rise step accordingly.

[0010] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0011] 1. The voltage control method for electrical equipment provided by this invention, through multi-dimensional parameter dynamic coupling analysis based on the operating power of the target electrical appliance and the operating status of the power supply channel, adjusts the soft-start capacitor of the voltage regulator and related control parameters in real time and accurately, thereby realizing continuous and stable control of the voltage of the target electrical appliance and its associated electrical appliances, effectively suppressing the violent voltage fluctuations caused by sudden changes in the operating status of the target electrical appliance, thus ensuring the coordinated and stable operation of various related electrical appliances in the multi-equipment system, improving the dynamic response capability and overall stability of the power supply system, and effectively solving the problem of violent fluctuations in the target electrical appliance and its associated electrical appliances caused by sudden changes in the operating status of the target electrical appliance in the prior art.

[0012] 2. This invention, based on the initial adjustment of the soft-start capacitor of the voltage regulator and combined with the trial operation parameters during the trial operation of the target electrical appliance, judges the trial operation quality, thereby dynamically adjusting the loop bandwidth of the voltage regulator, and thus effectively suppressing voltage ripple and frequency noise, improving the power supply quality of electrical equipment, and ensuring the stability and reliability of the target electrical appliance operation.

[0013] 3. This invention obtains the power difference of the target electrical appliance and couples it with the preset stable operating parameters in the database. Combined with the voltage regulator loop bandwidth adjustment results, it realizes the initial and secondary adjustment of the soft-start capacitor. Furthermore, by dynamically adjusting the rise step of the PWM duty cycle, it further optimizes the voltage regulator startup and operation process, thereby reducing startup surge current and load switching impact, and improving the overall stability of power supply to electrical equipment.

[0014] 4. This invention monitors the operating quality values ​​of each associated electrical appliance in real time, dynamically analyzes the fluctuation judgment results, and adjusts the rise step of the voltage regulator's PWM duty cycle based on the database. This enables the balance adjustment of power supply among multiple devices, prevents local voltage fluctuations from affecting the overall system stability, and effectively ensures the safe and coordinated operation of multiple devices in complex electrical environments.

[0024] The technical solution of the present invention will now be described with reference to the accompanying drawings.

Any embodiment or design described as "exemplary" in the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner.

[0026] In the embodiments of this invention, the terms "image" and "picture" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, they convey the same meaning. Similarly, the terms "of," "corresponding (relevant)," and "corresponding" may sometimes be used interchangeably. It should be noted that, without emphasizing the distinction between them, they convey the same meaning.

[0027] In this embodiment of the invention, sometimes a subscript such as W1 may be written in a non-subscript form such as W1. When the difference is not emphasized, the meaning they express is the same.

[0028] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0029] like Figure 1The diagram shows a flowchart of a voltage control method for electrical equipment provided in an embodiment of this application. The method includes the following steps: S1. When the central controller receives a signal indicating a voltage increase in an electrical appliance, it marks the appliance as a target appliance, obtains the target power output and the stable operating parameters of the target power channel, and analyzes the initial soft-start capacitor value of the voltage regulator. The stable operating parameters reflect the stability capability of the target power channel. S2. Based on the initial soft-start capacitor value, a trial run test is performed on the target appliance to obtain its operating quality value. This value is then processed to obtain the trial run quality judgment result. If the trial run quality judgment result is qualified... If the initial soft-start capacitor value is not adjusted, the system will maintain operation; otherwise, step S3 will be executed. The target appliance's operating quality value is used to reflect the stability of the target appliance's operation. S3: Obtain the voltage regulator's ripple frequency, adjust the corresponding loop bandwidth, and analyze again to obtain the target appliance's second operating quality value. Then, process the result of the initial adjustment quality difference judgment and perform the corresponding voltage regulator's secondary adjustment. S4: After receiving the voltage regulator's secondary adjustment signal, the central controller will test each associated appliance to obtain the operating quality value of each associated appliance. Then, process the result of the fluctuation judgment of each associated appliance and perform the corresponding voltage regulator's PWM duty cycle increase step adjustment.

[0030] In this embodiment, as Figure 2 The diagram shown is a macroscopic flowchart of a voltage control method for electrical equipment provided in this application embodiment. When the central controller receives a signal indicating a voltage increase in an electrical appliance, it marks the appliance as a target appliance and obtains the initial soft-start capacitor value. Subsequently, the target appliance undergoes a trial run test and its operating quality is assessed. If the assessment result is satisfactory, operation is directly maintained; otherwise, the ripple frequency of the voltage regulator is obtained and loop bandwidth is adjusted. A second operating quality value for the target appliance is then obtained and assessed. If the assessment result is the first initial adjustment result, the voltage regulator output voltage ramp-up rate is reduced; if it is the second initial adjustment result, the voltage regulator startup capacitor value is increased a second time. After completing the above adjustments, each associated appliance undergoes a trial run test and its fluctuation is assessed. If any associated appliance is found to be unqualified, the voltage regulator PWM duty cycle ramp-up step is adjusted; otherwise, the process ends directly.

[0031] In high-precision research environments such as university and corporate laboratories, numerous precision instruments and testing equipment have extremely high requirements for power supply stability. Voltage regulators provide stable regulation support for these precision instruments, ensuring the accuracy of experimental data and the normal operation of the equipment. Because the operating status of instruments changes frequently during experiments, power supply equipment needs to respond promptly to dynamic load changes, maintaining continuous and stable output voltage to prevent voltage fluctuations from negatively impacting experimental results and equipment safety. For example, in a corporate electrical and automation laboratory, researchers use a programmable DC power supply to power an unmanned target testing device. This testing device contains multiple high-precision sensors and control modules, which are extremely sensitive to voltage fluctuations. If the output voltage of the power supply equipment fluctuates drastically, it will directly lead to sensor data distortion, affecting the repeatability and accuracy of the experiment, and may even cause the equipment to restart or be damaged. Therefore, it is essential to ensure that the power supply equipment can achieve dynamic and precise voltage control in response to changes in the operating status of the target electrical appliances. The control steps in this application can all be achieved through automated adjustment, requiring no human intervention or manual processing of the internal structures of various devices (such as voltage regulators).

[0032] It should be noted that the absolute difference is a positive number, that is, the absolute value of the difference. Multiplicative coupling processing is a multiplication process.

[0033] Furthermore, the initial adjustment soft-start capacitor value of the voltage regulator is obtained. Specifically, the following methods are used: The current operating power of the target appliance is obtained, and the absolute difference between this value and the target operating power is processed to obtain the power difference of the target appliance. Based on this power difference, the database is matched to obtain the operating stability impact coefficient of the target appliance. The operating stability execution parameters of the target power channel are obtained, including voltage margin, output power margin, and voltage ripple rate. A preset operating stability execution benchmark set is obtained from the database, and an adaptive comparative analysis is performed with the operating stability execution parameters of the target power channel to obtain the comparative analysis results. Based on these results, corresponding weighting factors are introduced for coupling processing to obtain the coupling processing results. Based on these coupling processing results and the operating stability impact coefficient of the target appliance, a multiplicative coupling processing is performed to obtain the stable operating value of the target power channel. The operating stability execution benchmark set is packaged... This includes voltage margin reference value, output power margin reference value, and voltage ripple rate reference value; obtaining the preset operating stability threshold of the target power channel in the database and comparing it with the operating stability value of the target power channel to obtain the operating stability judgment result of the target power channel. If the operating stability judgment result of the target power channel is qualified, the soft start capacitor value adjustment is not performed; otherwise, the soft start capacitor value adjustment is performed, and the current operation is maintained; the soft start capacitor value adjustment is performed by: analyzing the degree of difference between the operating stability value of the target power channel and the operating stability threshold of the target power channel to obtain the degree of difference in operating stability of the target power channel; matching the degree of difference in operating stability of the target power channel with the database to obtain the soft start capacitor value adjustment value; increasing the soft start capacitor value of the regulator based on the soft start capacitor value adjustment value to obtain the initial adjustment soft start capacitor value of the regulator.

[0034] In this embodiment, it should be noted that the adaptive comparison analysis is specifically based on the division of the mutual influence relationship (such as the influence trend) between the stable execution parameters of the target power channel and the stable execution benchmark set.

[0035] The stable operating parameters of the target power channel (including voltage margin, output power margin, and voltage ripple rate) can be obtained through a computer backend system. This system can be connected to the actual circuit, and data can be obtained from sensors (such as ripple analyzers and digital oscilloscopes) within the circuit. Voltage margin reflects the safety margin of the voltage and directly affects the power supply stability of electrical equipment; output power margin determines the overall power supply capacity of the equipment. Voltage ripple rate represents the high-frequency fluctuation component in the voltage signal; excessive ripple will affect the stable current supply to the equipment.

[0036] It should be noted that the operational stability impact coefficient of the target appliances is obtained by matching the power difference of the target appliances with the database. The specific method is as follows: obtain the historical power difference of the target appliances stored in the database, and perform difference processing on the power difference of the target appliances to obtain the historical power deviation value of the target appliances. Obtain the preset power deviation threshold of the target appliances in the database and compare it with the historical power deviation value of the target appliances. Historical target appliances whose power deviation value is less than the power deviation threshold of the target appliances are marked as historical control target appliances. Thus, each historical control target appliance and its power difference are obtained. The operational stability impact coefficient of the target appliances corresponding to the power difference of each historical control target appliance is obtained, and the average value is processed to obtain the operational stability impact coefficient of each historical control target appliance. The average value of the operational stability impact coefficient of each historical control target appliance is then processed and marked as the operational stability impact coefficient of the target appliances.

[0037] The specific method for obtaining the stable operating value of the target power channel is as follows:

[0038] ;

[0039] In the formula, PW represents the stable operating value of the target power channel, YU represents the voltage margin of the target power channel, WU represents the voltage margin reference value, YW represents the output power margin of the target power channel, WW represents the output power margin reference value, YB represents the voltage ripple rate of the target power channel, WB represents the voltage ripple rate reference value, XS represents the operating stability influence coefficient of the target appliance, τ1 represents the voltage margin weighting factor, τ2 represents the output power margin voltage margin weighting factor, and τ3 represents the voltage ripple rate voltage margin weighting factor.

[0040] Voltage margin weighting factors, output power margin weighting factors, and voltage ripple rate weighting factors can be obtained from a database. For example, the voltage margin weighting factor can be obtained by analyzing the historical voltage margin set stored in the database. The difference between each historical voltage margin in the historical voltage margin set and the current voltage margin is calculated to obtain the historical voltage margin difference value. A preset voltage margin difference threshold range in the database is obtained and compared with each historical voltage margin difference value. If a historical voltage margin difference value falls within the threshold range, the corresponding historical voltage margin value is obtained and marked as the historical reference voltage margin, thus obtaining each historical reference voltage margin. The historical reference voltage margin is then processed by removing extreme values ​​(maximum and minimum values) and its standard deviation is taken to obtain the standard deviation of the historical reference voltage margin. The database is used to obtain preset historical reference voltage margin weighting factors, historical control voltage margin standard deviation benchmarks, historical control voltage margin standard deviation difference gradients, and single-level adjustment amounts of voltage margin weighting factors. The difference between the historical control voltage margin standard deviation and the historical control voltage margin benchmark is calculated to obtain the historical control voltage margin standard deviation difference value. A multiple analysis is then performed on the historical control voltage margin standard deviation difference value and its gradient (dividing the historical control voltage margin standard deviation difference value by the historical control voltage margin standard deviation difference gradient value) to obtain the historical control voltage margin standard deviation difference gradient multiple. The voltage margin weighting factor is obtained by multiplying the gradient multiple of the historical reference voltage margin standard deviation difference by the single-level adjustment amount of the voltage margin weighting factor. This is then compared to the historical reference voltage margin standard deviation benchmark. If the historical reference voltage margin standard deviation is greater than the benchmark, the historical reference voltage margin weighting factor is added to the voltage margin weighting factor's comprehensive adjustment amount to obtain the final voltage margin weighting factor. Otherwise, the historical reference voltage margin weighting factor is subtracted from the comprehensive adjustment amount to obtain the final voltage margin weighting factor. Other weighting factors, such as the output power margin voltage margin weighting factor and the voltage ripple rate voltage margin weighting factor, are obtained in the same way as the voltage margin weighting factor. The historical control voltage margin standard deviation difference gradient represents the difference between the minimum values ​​of any two adjacent voltage margin control standard deviation gradient intervals. The single-level adjustment of the voltage margin weighting factor represents the amount of increase (or decrease) required in the voltage margin weighting factor for each increase (or decrease) in the voltage margin control standard deviation gradient of the next higher level. The number of voltage margin control standard deviation gradient intervals is several.

[0041] The initial soft-start capacitor value of the voltage regulator is obtained by increasing the soft-start capacitor value based on the soft-start capacitor adjustment value. Specifically, the initial soft-start capacitor value of the voltage regulator is obtained by adding the soft-start capacitor adjustment value to the soft-start capacitor value of the voltage regulator.

[0042] By obtaining the difference between the current operating power and the target operating power of the target electrical appliance, and combining this with key operational stability parameters of the target power channel, the operating stability value of the target power channel is obtained. This operating stability value serves as a comprehensive representation of the overall operating status of the appliance, accurately reflecting the power supply stability and load response capability of the power channel.

[0043] By adjusting the soft-start capacitor of the voltage regulator based on its stable operating value, the voltage startup process can be smoothed, reducing current surges and voltage fluctuations during startup. This effectively reduces the risk of sudden fluctuations in the target electrical appliance and its associated equipment. Compared to directly adjusting single parameters such as output voltage or current, the adjustment of the soft-start capacitor is more targeted and precise, enabling gradual voltage adjustment, improving the flexibility and reliability of the system response, ensuring stable power supply, and guaranteeing the safe operation of the target electrical appliance and the stability of its associated equipment.

[0044] It should also be noted that the specific method for obtaining the operational stability judgment result of the target power channel is as follows: compare the operational stability value of the target power channel with the operational stability threshold of the target power channel. If the operational stability value of the target power channel is above the operational stability threshold of the target power channel, then the operational stability judgment result of the target power channel is qualified; otherwise, the operational stability judgment result of the target power channel is unqualified.

[0045] The method to obtain the operational stability difference value of the target power channel is as follows: subtract the operational stability value of the target power channel from the operational stability threshold of the target power channel to obtain the difference value, and then divide the difference value by the operational stability threshold of the target power channel to obtain the operational stability difference value of the target power channel.

[0046] Furthermore, the trial operation quality assessment results are obtained through the following method: Trial operation is conducted based on the initial soft-start capacitor value of the voltage regulator to obtain the trial operation parameters of the target electrical appliance within the first trial operation cycle. These parameters include ripple amplitude, ripple frequency, and starting surge current. A preset trial operation allowable set is obtained from the database, including allowable values ​​for ripple amplitude, ripple frequency, and starting surge current. A proportional analysis is performed based on the ripple amplitude and starting surge current compared to the allowable values, yielding the proportional analysis results. Finally, a proportional analysis is performed based on the ripple frequency and the allowable ripple frequency value. A difference degree analysis is performed to obtain the difference degree analysis results. Based on the ratio analysis results and the difference degree analysis results, corresponding weighting factors are introduced for coupling processing to obtain the target electrical appliance operating quality value. The trial operation allowable set includes the allowable value of ripple amplitude, the allowable value of ripple frequency, and the allowable value of starting surge current. The preset target electrical appliance operating quality threshold in the database is obtained and compared with the target electrical appliance operating quality value to obtain the trial operation quality judgment result. If the target electrical appliance operating quality value is above the target electrical appliance operating quality threshold, the trial operation quality judgment result is qualified; otherwise, the trial operation quality judgment result is unqualified.

[0047] In this embodiment, the trial operation parameters, including ripple amplitude, ripple frequency, and initiation surge current, can be obtained through a computer backend system. The computer backend system can be connected to the actual circuit, and the corresponding data can be obtained by accessing the sensors (such as ripple analyzers and digital oscilloscopes) in the actual circuit.

[0048] The specific method for obtaining the operating quality value of the target electrical appliance is as follows:

[0049] ;

[0050] In the formula, ZL represents the target electrical appliance operating quality value, ZF represents the ripple amplitude, LF represents the allowable ripple amplitude value, ZV represents the ripple frequency, LV represents the allowable ripple frequency value, ZY represents the starting surge current, LY represents the allowable starting surge current value, ω1 represents the ripple amplitude weighting factor, ω2 represents the ripple frequency weighting factor, and ω3 represents the starting surge current weighting factor.

[0051] Ripple amplitude weighting factor, ripple frequency weighting factor, and initiation surge current weighting factor can be obtained from a database. For example, the ripple amplitude weighting factor can be obtained by analyzing the historical ripple amplitude set stored in the database. The difference between each historical ripple amplitude value in the historical ripple amplitude set and the current ripple amplitude value is calculated to obtain the historical ripple amplitude difference. A preset threshold range for ripple amplitude difference in the database is obtained and compared with each historical ripple amplitude difference. If a historical ripple amplitude difference falls within the threshold range, the corresponding historical ripple amplitude value is obtained and marked as the historical reference ripple amplitude value, thus obtaining each historical reference ripple amplitude value. The extreme values ​​(maximum and minimum values) of each historical reference ripple amplitude value are then removed, and the standard deviation is taken to obtain the standard deviation of the historical reference ripple amplitude value. Retrieve the preset historical reference ripple amplitude weighting factor, historical control ripple amplitude standard deviation benchmark, historical control ripple amplitude standard deviation difference gradient, and single-level adjustment of the ripple amplitude weighting factor from the database. Difference is processed between the historical control ripple amplitude standard deviation and the historical control ripple amplitude standard deviation benchmark to obtain the historical control ripple amplitude standard deviation difference value. A fold analysis is then performed on the historical control ripple amplitude standard deviation difference value and the historical control ripple amplitude standard deviation difference gradient (dividing the historical control ripple amplitude standard deviation difference value by the historical control ripple amplitude standard deviation difference gradient value) to obtain the historical control ripple amplitude amplitude standard deviation difference gradient fold. The gradient multiple of the difference in the standard deviation of the historical reference ripple amplitude is multiplied by the single-level adjustment of the ripple amplitude weighting factor to obtain the comprehensive adjustment of the ripple amplitude weighting factor. This is then compared to the historical reference ripple amplitude standard deviation benchmark. If the historical reference ripple amplitude standard deviation is greater than the benchmark, the historical reference ripple amplitude weighting factor is added to the comprehensive adjustment of the ripple amplitude weighting factor to obtain the final ripple amplitude weighting factor. Otherwise, the historical reference ripple amplitude weighting factor is subtracted from the comprehensive adjustment of the ripple amplitude weighting factor to obtain the final ripple amplitude weighting factor. Other weighting factors, such as the ripple frequency weighting factor and the initiation surge current weighting factor, are obtained in the same way as the ripple amplitude weighting factor. The historical control ripple amplitude standard deviation difference gradient represents the difference between the minimum values ​​of any two adjacent ripple amplitude control standard deviation gradient intervals. The single-level adjustment of the ripple amplitude weighting factor represents the amount of increase (or decrease) required for the corresponding ripple amplitude weighting factor to increase (or decrease) by one level of the ripple amplitude control standard deviation gradient. The number of ripple amplitude control standard deviation gradient intervals is several.

[0052] By conducting trial runs based on the initial soft-start capacitor value of the voltage regulator, key operating parameters of the target electrical appliances are collected in real time to comprehensively evaluate the equipment's operating status, thereby ensuring the effectiveness and accuracy of the adjustment parameters. Through proportional analysis and weighted coupling with a preset trial run allowable set in the database, objective operating quality values ​​are obtained, avoiding instability caused by blind adjustments, and effectively verifying the impact of voltage regulator adjustments on the performance of the target electrical appliances.

[0053] Furthermore, corresponding loop bandwidth adjustment is performed. The specific method is as follows: obtain the preset ripple frequency threshold in the database and compare it with the ripple frequency of the voltage regulator to obtain the voltage regulator loop bandwidth determination result. If the voltage regulator's ripple frequency is above the ripple frequency threshold, the voltage regulator loop bandwidth determination result is to perform loop bandwidth reduction adjustment; otherwise, the voltage regulator loop bandwidth determination result is not to perform loop bandwidth reduction adjustment. To perform loop bandwidth reduction adjustment, the specific method is as follows: analyze the degree of difference between the voltage regulator's ripple frequency and the ripple frequency threshold to obtain the ripple frequency difference value. Match the ripple frequency difference value with the database to obtain the loop bandwidth reduction adjustment value, and then perform loop bandwidth reduction adjustment processing.

[0054] In this embodiment, the difference between the ripple frequency of the voltage regulator and the ripple frequency threshold is analyzed to obtain the ripple frequency difference value. The specific method is as follows: the ripple frequency difference is obtained by subtracting the ripple frequency threshold from the ripple frequency of the voltage regulator. The ripple frequency difference value is obtained by dividing the ripple frequency difference by the ripple frequency threshold.

[0055] The loop bandwidth reduction adjustment value is obtained by matching the ripple frequency difference value with the database. The specific method is as follows: obtain the historical loop bandwidth reduction adjustment value corresponding to the historical ripple frequency difference value stored in the database, and average the historical loop bandwidth reduction adjustment value to obtain the historical loop bandwidth reduction adjustment average value, which is used as the loop bandwidth reduction adjustment value.

[0056] Ripple frequency is an important indicator for measuring high-frequency interference and noise in voltage output. When the ripple frequency exceeds a threshold, it indicates strong high-frequency fluctuations in the power supply system, which can affect the stable operation of electrical equipment. Therefore, it is necessary to reduce the loop bandwidth of the voltage regulator to suppress high-frequency noise, enhance the anti-interference capability of the power supply system, and thus improve the stability and reliability of the power supply. Conversely, when the ripple frequency is below the threshold, it indicates that the system is operating relatively stably and no additional adjustment is required.

[0057] Regardless of whether loop bandwidth adjustment is performed, a second operating quality value analysis of the target electrical appliance is necessary. This is to dynamically monitor the adjustment effect and the actual operating status of the equipment, ensuring that the adjustment measures are effective and meet system requirements. Based on the different performance of the second operating quality value (whether it exceeds the second operating quality difference threshold), corresponding adjustment strategies can be flexibly executed to achieve precise control and optimization, ensuring the overall operational stability and efficiency of the target electrical appliance and its associated equipment, and avoiding blind adjustment.

[0058] Furthermore, the second operating quality value of the target appliance is obtained by analyzing the voltage regulator loop bandwidth determination result. If the voltage regulator loop bandwidth determination result indicates that loop bandwidth reduction adjustment should be performed, then loop bandwidth reduction adjustment should be performed, and the operating quality value of the target appliance should be obtained again after adjustment and recorded as the second operating quality value of the target appliance. If the voltage regulator loop bandwidth determination result indicates that loop bandwidth reduction adjustment should not be performed, then loop bandwidth reduction adjustment should not be performed, and the operating quality value of the target appliance at this time should be marked as the second operating quality value of the target appliance.

[0059] In this embodiment, based on the voltage regulator loop bandwidth determination result, loop bandwidth reduction adjustment is flexibly executed or skipped to ensure the targeting and effectiveness of the adjustment measures. When adjustment is determined to be necessary, loop bandwidth reduction adjustment is performed based on the loop bandwidth reduction adjustment value to effectively suppress voltage ripple and high-frequency interference, improving the operating quality of the target electrical appliance. When adjustment is determined not to be necessary, loop bandwidth reduction adjustment is not performed to reduce the impact on normal equipment operation. Subsequently, the adjusted operating quality value of the target electrical appliance is obtained as a second operating quality value for dynamically evaluating the adjustment effect and ensuring that the electrical equipment maintains stable operation under different operating conditions.

[0060] Furthermore, the loop bandwidth reduction adjustment value is obtained by matching the ripple frequency difference value with the database to obtain the loop bandwidth influence coefficient; analyzing the difference between the target appliance's operating quality value and the target appliance's operating quality threshold to obtain the target appliance's operating quality difference value; matching the target appliance's operating quality difference value with the database to obtain the first loop bandwidth adjustment value; and performing multiplicative coupling processing between the first loop bandwidth adjustment value and the loop bandwidth influence coefficient to obtain the loop bandwidth reduction adjustment value.

[0061] In this embodiment, the loop bandwidth influence coefficient is obtained by matching the ripple frequency difference value with the database. The specific method is as follows: obtain the historical ripple frequency difference value in the database and perform difference processing with the historical ripple frequency difference value to obtain the difference value of the historical ripple frequency difference. Obtain the preset threshold of the ripple frequency difference value in the database and compare it with the difference value of the historical ripple frequency difference. Mark the historical ripple frequency difference value that is less than the threshold of the ripple frequency difference value as the historical reference ripple frequency difference value. Thus, obtain the historical ripple frequency difference value. Obtain the loop bandwidth influence coefficient corresponding to the historical ripple frequency difference value and perform average processing to obtain the average value of the historical loop bandwidth influence coefficient, and use it as the loop bandwidth influence coefficient.

[0062] The degree of difference between the target appliance's operating quality value and the target appliance's operating quality threshold is analyzed to obtain the degree of difference in the target appliance's operating quality. Specifically, the operating quality difference is obtained by subtracting the target appliance's operating quality value from the target appliance's operating quality threshold, and then dividing the operating quality difference by the target appliance's operating quality threshold.

[0063] The loop bandwidth first adjustment value is obtained by matching the target appliance's operating quality difference value with the database. Specifically, the method involves obtaining a preset range of operating quality difference values ​​for each target appliance in the database, along with the corresponding first adjustment reference value for the loop bandwidth. This value is then compared with the target appliance's operating quality difference value. If the target appliance's operating quality difference value falls within a preset range, the first adjustment reference value for the loop bandwidth corresponding to that range is used as the first adjustment value for the loop bandwidth. The target appliance's operating quality difference value range is a relatively small range, and the difference between any two adjacent target appliance operating quality difference value ranges is 1.

[0064] Furthermore, a secondary adjustment of the voltage regulator is performed. Specifically, the following steps are taken: First, a preset target appliance trial operation quality threshold is obtained from the database, and its difference from the target appliance's second operation quality value is analyzed to obtain a second operation quality difference value. Then, a preset second operation quality difference threshold is obtained from the database, and compared with the second operation quality difference value to obtain an initial adjustment quality difference determination result. If the second operation quality difference value is less than the second operation quality difference threshold, the initial adjustment quality difference determination result is the first initial adjustment determination result. If the second operation quality difference value is greater than the second operation quality difference threshold, the initial adjustment quality difference determination result is the second initial adjustment determination result. If the initial adjustment quality difference determination result is the first initial adjustment determination result, the voltage regulator output voltage ramp-up rate is reduced. If the initial adjustment quality difference determination result is the second initial adjustment determination result, the voltage regulator starting capacitor value is increased a second time.

[0065] In this embodiment, by analyzing the difference between the second operating quality value of the target electrical appliance and the preset quality threshold, two initial adjustment judgment results are determined, enabling a targeted secondary adjustment strategy. When the judgment result is the first initial adjustment judgment result, it indicates that the operating quality of the target electrical appliance differs little from the preset threshold. In this case, only the voltage regulator output voltage ramp-up rate needs to be reduced for finer adjustment, avoiding over-adjustment that could lead to system instability. When the judgment result is the second initial adjustment judgment result, it indicates that the operating quality difference is large. A more significant adjustment is needed by increasing the voltage regulator startup capacitor value to effectively improve system stability and ensure the smooth and efficient operation of electrical equipment.

[0066] The specific method for performing a secondary increase adjustment of the regulator's starting capacitor value is as follows: First, obtain the preset second operating quality difference gradient, the regulator's starting capacitor value improvement coefficient corresponding to each gradient, and the regulator's starting capacitor value improvement benchmark value from the database. Second, perform absolute difference processing based on the second operating quality difference degree value and the second operating quality difference degree threshold to obtain the second operating quality basic difference value. Third, perform multiplier analysis based on the second operating quality basic difference value and the second operating quality difference gradient to obtain the second operating quality gradient multiplier. Fourth, perform multiplicative coupling processing based on the second operating quality gradient multiplier and the regulator's starting capacitor value improvement coefficient corresponding to each gradient to obtain the secondary increase value of the regulator's starting capacitor value. Fifth, add the secondary increase value of the regulator's starting capacitor value to the regulator's starting capacitor value improvement benchmark value to obtain the comprehensive value of the secondary increase in the regulator's starting capacitor value. Sixth, adjust the current regulator's starting capacitor value based on the comprehensive value of the secondary increase in the regulator's starting capacitor value, thereby completing the secondary increase adjustment of the regulator's starting capacitor value. It should be noted that the benchmark value for increasing the regulator's starting capacitor value is the benchmark value for increasing the regulator's starting capacitor value corresponding to the second operating quality difference threshold, which represents the minimum increase required for the regulator's starting capacitor value. The regulator's starting capacitor value increase coefficient corresponding to a single gradient refers to the required increase coefficient for the regulator's starting capacitor value for each increase of one level in the second operating quality gradient.

[0067] Furthermore, the regulator output voltage ramp-up rate is reduced and adjusted. Specifically, the following method is used: First, a preset second operating quality difference gradient, a voltage ramp-up rate reduction coefficient corresponding to a single gradient, and a baseline value for output voltage ramp-up rate reduction are obtained from the database. Second, an absolute difference is processed between the second operating quality difference value and the second operating quality difference threshold to obtain a basic difference in second operating quality. Third, a multiplicative analysis is performed between the basic difference in second operating quality and the second operating quality difference gradient to obtain a second operating quality gradient multiplier. Fourth, a multiplicative coupling process is performed between the second operating quality gradient multiplier and the voltage ramp-up rate reduction coefficient corresponding to a single gradient to obtain a voltage ramp-up rate reduction value. Fifth, a coupling process is performed between the voltage ramp-up rate reduction value and the baseline value for output voltage ramp-up rate reduction to obtain a comprehensive value for output voltage ramp-up rate reduction. Finally, the current regulator output voltage ramp-up rate is reduced and adjusted based on the comprehensive value for output voltage ramp-up rate reduction, thus completing the regulator output voltage ramp-up rate reduction adjustment.

[0068] In this embodiment, it should be noted that a multiplier analysis is performed based on the second operating quality baseline difference and the second operating quality difference gradient to obtain the second operating quality gradient multiplier. Specifically, the second operating quality baseline difference is divided by the second operating quality difference gradient to obtain the second operating quality gradient multiplier. A combined value for the reduction in the voltage ramp-up rate is obtained by coupling the voltage ramp-up rate reduction value with the output voltage ramp-up rate reduction reference value. Specifically, the combined value for the reduction in the voltage ramp-up rate is added to the output voltage ramp-up rate reduction reference value. The voltage ramp-up rate reduction coefficient corresponding to a single gradient refers to the coefficient required to reduce the voltage ramp-up rate for each increase of one level in the second operating quality gradient multiplier.

[0069] It should be noted that the output voltage ramp-up rate reduction reference value is the output voltage ramp-up rate reduction reference value corresponding to the second operating quality difference threshold, which is used to represent the minimum adjustment amount of the minimum output voltage ramp-up rate reduction.

[0070] By accurately calculating the absolute difference between the second operational quality difference of the target electrical appliance and a preset threshold, and combining this with the operational quality difference gradient in the database and the corresponding voltage rise rate reduction coefficient, dynamic and graded adjustment of the voltage regulator's output voltage rise rate is achieved. This allows for flexible determination of the voltage rise rate reduction based on the actual magnitude of the operational quality difference, avoiding over- or under-adjustment and ensuring a smoother and more stable voltage change process. Through the coupling of the comprehensive reference value and the calculation results, the accuracy and adaptability of the adjustment are improved, effectively reducing equipment impact caused by voltage surges and ensuring the operational stability and safety of the target electrical appliance and related equipment.

[0071] Furthermore, the corresponding adjustment of the regulator's PWM duty cycle rise step is performed. Specifically, the following steps are taken: First, obtain the remaining electrical appliances controlled by the regulator and mark them as associated appliances. Second, obtain the trial operation parameters of each associated appliance and analyze them to obtain the operating quality value of each associated appliance. The trial operation parameters include ripple amplitude, ripple frequency, and starting surge current. Third, obtain the preset operating quality thresholds for each associated appliance in the database and compare them with the operating quality values ​​of each associated appliance to obtain the fluctuation judgment result of each associated appliance. If the fluctuation judgment results of each associated appliance are all qualified, the regulator's PWM duty cycle rise step will not be adjusted. If a certain fluctuation judgment result exists... If the fluctuation judgment result of a related electrical appliance is unqualified, the PWM duty cycle rise step of the voltage regulator is adjusted. The specific method for adjusting the PWM duty cycle rise step of the voltage regulator is as follows: Based on the difference between the operating quality value of each related electrical appliance and the operating quality threshold of each related electrical appliance, the difference value of the operating quality of each related electrical appliance is obtained, and the related electrical appliance corresponding to the maximum value of the difference value of the operating quality of the related electrical appliances is recorded as the fluctuation-affected appliance; based on the quality fluctuation value of the fluctuation-affected appliance, the database is matched to obtain the adjustment ratio of the PWM duty cycle rise step of the voltage regulator, thereby reducing the PWM duty cycle rise step of the voltage regulator.

[0072] In this embodiment, it should be noted that the specific steps for obtaining the trial operation parameters of each associated electrical appliance and analyzing them to obtain the operating quality value of each associated electrical appliance are exactly the same as the method for analyzing the operating quality value of the target electrical appliance based on the trial operation parameters of the target electrical appliance.

[0073] The fluctuation judgment results of each associated electrical appliance are obtained by comparing the operating quality value of each associated electrical appliance with the corresponding operating quality threshold. If the operating quality of an associated electrical appliance is above the operating quality threshold of its corresponding associated electrical appliance, the fluctuation judgment result of that associated electrical appliance is qualified. If the operating quality of an associated electrical appliance is below the operating quality threshold of its corresponding associated electrical appliance, the fluctuation judgment result of that associated electrical appliance is unqualified.

[0074] like Figure 3 As shown, Figure 3The flowchart of the secondary adjustment process of a voltage control method for electrical equipment provided in this application embodiment is as follows: First, the ripple frequency of the voltage regulator is obtained and compared with a preset ripple frequency threshold in the database to obtain the loop bandwidth determination result of the voltage regulator; if loop bandwidth reduction adjustment is required, the loop bandwidth influence coefficient is obtained by matching the ripple frequency difference value with the database, and multiplicatively coupled with the first adjustment value of the loop bandwidth obtained by matching the operating quality difference value of the target electrical appliance to obtain the loop bandwidth reduction adjustment value and implement the adjustment. Then, the operating quality value of the target electrical appliance is obtained again and recorded as the second operating quality value; if loop bandwidth reduction adjustment is not performed, the operating quality value of the target electrical appliance is directly obtained as the second operating quality value. Next, the difference between the second operating quality value and the target electrical appliance trial operation quality threshold is analyzed to obtain the second operating quality difference value, which is then compared with the preset second operating quality difference threshold to obtain the initial adjustment quality difference judgment result. If the judgment result is the first initial adjustment judgment result, the voltage regulator output voltage ramp-up rate is reduced; if it is the second initial adjustment judgment result, the voltage regulator starting capacitor value is increased a second time, and the voltage control process is finally completed.

[0075] By acquiring and analyzing the operational quality parameters of each associated appliance controlled by the voltage regulator in real time, the system comprehensively understands key indicators such as voltage ripple, frequency, and inrush current of the associated appliances, thereby accurately assessing their operational status and fluctuations. Based on a comparison of the operational quality of the associated appliances with preset thresholds, the system intelligently determines whether to adjust the PWM duty cycle rise step of the voltage regulator, preventing the negative impact of voltage adjustment of the target appliance from spreading to associated appliances. By identifying the associated appliance with the greatest impact from fluctuations and matching its quality fluctuation value, the system achieves fine adjustment of the PWM duty cycle rise step of the voltage regulator, effectively reducing system interference and fluctuations during voltage adjustment, and ensuring the operational stability and power supply quality of the target appliance and its associated equipment throughout the entire electrical system.

[0076] Adjusting the target appliance based on the operational quality of its associated appliances is crucial because voltage adjustments to the target appliance directly or indirectly affect the power supply stability of other associated appliances controlled by the same voltage regulator. Voltage fluctuations and startup surges generated by the target appliance during operation can easily cause voltage ripple and load fluctuations in associated appliances, leading to instability in the entire power supply system. By monitoring the operational quality of each associated appliance, the ripple propagation effect caused by adjustments to the target appliance can be detected in a timely manner. This allows for fine-tuning of the voltage regulator parameters of the target appliance (such as the PWM duty cycle rise step), effectively suppressing the spread and accumulation of fluctuations, reducing interference to associated appliances, and achieving coordinated and stable operation among multiple devices.

The voltage control system includes: a voltage regulator initial adjustment module, a target appliance trial operation module, a voltage regulator secondary adjustment module, and a related adjustment module. The voltage regulator initial adjustment module is used to mark the appliance as a target appliance after the central controller receives a voltage increase signal, obtain the target execution power and stable operation parameters of the target power channel, and analyze the initial adjustment soft-start capacitor value of the voltage regulator. The target appliance trial operation module is used to perform trial operation testing of the target appliance based on the initial adjustment soft-start capacitor value, obtain the operating quality value of the target appliance, and then process the results. The system obtains the trial operation quality judgment result. If the trial operation quality judgment result is qualified, the system maintains operation with the initial adjustment soft start capacitor value; otherwise, it executes the voltage regulator secondary adjustment module. The voltage regulator secondary adjustment module is used to obtain the voltage regulator's ripple frequency, perform corresponding loop bandwidth adjustment, and analyze again to obtain the second operating quality value of the target electrical appliance. Then, it processes the result of the initial adjustment quality difference judgment and performs the corresponding voltage regulator secondary adjustment. The associated adjustment module is used by the central controller to perform trial operation tests on each associated electrical appliance after receiving the voltage regulator secondary adjustment signal, obtain the operating quality value of each associated electrical appliance, process the result of the fluctuation judgment of each associated electrical appliance, and then adjust the voltage regulator's PWM duty cycle rise step accordingly.

[0080] In summary, this embodiment achieves continuous and stable voltage control of the target appliance and its associated appliances by using multi-dimensional parameter dynamic coupling analysis based on the operating power of the target appliance and the operating status of the power supply channel, and by adjusting the soft-start capacitor of the voltage regulator and related control parameters in real time.
