In the related art, in order to meet the power consumption requirement of high-power equipment, a plurality of power modules are usually connected in parallel to supply power to the equipment, the parallel power supply is usually specially designed according to the specific power consumption requirement of specific equipment, that is, one set of parallel power supply is only suitable for certain or some specific equipment, and for other equipment, the power required by the equipment in the process of reaching the optimal working state cannot be provided, and if unmatched parallel power supplies are adopted to supply power to the equipment, the equipment cannot reach the optimal working state, or even is damaged.
In view of the above problems in the related art, the embodiments of the present disclosure provide a voltage adjustment scheme for a parallel power supply, which can adjust the reference voltage of each power module in the parallel power supply according to the power supply requirement of a load, so that the output voltage of the parallel power supply reaches the optimal working voltage of the load, and avoid the waste of load performance. And different parallel power supplies do not need to be designed according to different loads, so that the design cost is saved.
For example, fig. 1 is a schematic diagram of a power supply scenario provided by an embodiment of the present disclosure, in which a power module 11, a power module 12, and a power module 13 are connected in parallel to supply power to a data processing device 14. The power module 11, the power module 12 and the power module 13 are all internally provided with a voltage regulating module. When the voltage adjustment method provided by the embodiment of the present disclosure is executed, the data processing device 14 collects the output voltages of the power module 11, the power module 12, and the power module 13 after being connected in parallel and the reference voltages of the power module 11, the power module 12, and the power module 13, compares the collected output voltages with the optimal working voltage of the data processing device 14 itself, generates a control signal if the collected output voltages are not consistent with the optimal working voltage of the data processing device 14, and adjusts the reference voltages of the power module 11, the power module 12, and the power module 13 until the output voltages of the power module 11, the power module 12, and the power module 13 after being connected in parallel are consistent with the optimal working voltage. In this way, the data processing device 14 operating at the optimum operating voltage can achieve the optimum operating state. Of course, the description is given only by taking the example of parallel power supply of three power modules, but this does not prevent the voltage adjustment method from being applied to the case where two or more than three power modules are connected in parallel.
An embodiment of the present application provides a method for adjusting voltage of a parallel power supply, which is applicable to a power supply system in which a parallel power supply is used to supply power to a data processing device, and the data processing device can perform at least one of the following data processing: setting, calculating, judging, transmitting, storing and managing based on or to the data. As an embodiment, the data processing may be data processing related to a digital voucher by a data processing device, the digital voucher being obtainable by the data processing, and the data processing device may be a digital voucher processing device.
For example, fig. 2 is a flowchart of a parallel power supply voltage adjustment method provided by an embodiment of the present disclosure, which may be executed by a data processing device connected to a parallel power supply, as shown in fig. 2, and the method includes the following steps:
The parallel power supply referred to in this embodiment may be formed by connecting two or more power supply modules in parallel. In the power modules, the reference voltages of the power modules can be the same or different, the output voltages of the power modules and the reference voltages are in a linear relation, and the reference voltages of the power modules can be adjusted through the built-in voltage regulating modules of the power modules. In practice, in order to ensure the output accuracy of the power modules, before the power modules are incorporated into the parallel power supply, the reference voltage of the power modules may be calibrated by the voltage regulating module in the power modules to achieve high-accuracy voltage output, where the adjusting method of the power module voltage includes, but is not limited to, adjusting the reference voltage of the power modules to a corresponding value by using the correlation between the reference voltage and the output voltage of the power modules, so as to obtain the target output voltage.
The reference voltage information referred to in this embodiment includes, but is not limited to, the current reference voltage of the power module, and the association relationship between the reference voltage of the power module and the output voltage, where the association relationship can be obtained by detecting with a relevant detection means.
In performing the operation of acquiring the output voltage information of the parallel power supply and the reference voltage information of each power supply module constituting the parallel power supply, any one of the following acquisition manners may be adopted, but not limited to:
in a first mode, the data processing device can acquire the output voltage information of the parallel power supply and the reference voltage information of each power supply module from the parallel power supply through the connection between the data processing device and the parallel power supply.
And in the second mode, the output voltage information of the parallel power supply and the reference voltage information of each power supply module are input by a user. For example, in a possible implementation, a user interaction interface may be output to a user, and the interface may include a prompt message and an information input area, where the prompt message is used to instruct the user to input what kind of information and an input position, so that the user inputs the output voltage information of the parallel power supplies and the reference voltage information of each power supply module in the parallel power supplies in the information input area according to the instruction of the prompt message.
And 102, determining whether the output voltage of the parallel power supply is consistent with the preset optimal working voltage or not based on the output voltage information.
In an actual scene, each device has an optimal working voltage, the optimal working voltage is generally calibrated when the device leaves a factory, and the device can achieve good performance only when the device works on the optimal working voltage of the device in the using process. For example, the optimal computational power consumption ratio can only be achieved when the digital voucher processing equipment works at the optimal working voltage, and in order to avoid computational power waste, the digital voucher processing equipment is generally required to work at the optimal working voltage in actual working conditions. For example, a common method is to compare the output voltage of the power supply with the optimal operating voltage, if the output voltage is consistent with the optimal operating voltage, the digital certificate processing device is judged to have operated in the optimal state, and if the output voltage is inconsistent with the optimal operating voltage, the digital certificate processing device is judged not to have operated in the optimal state. Of course, the above description is only an exemplary description of the digital certificate processing device, but does not prevent other devices, such as a super computer, a server, etc., from determining whether the device itself or other devices reach the optimal operating state by using the above method.
And 103, if the output voltages are not consistent with the optimal working voltage, generating a control signal based on the reference voltage information of each power supply module, so that each power supply module in the parallel power supply adjusts the reference voltage of the power supply module based on the control signal, and the output voltage of the power supply module is consistent with the optimal working voltage.
In practice, the reference voltage and the output voltage of the power module are in a linear correlation relationship within a certain range, and if the reference voltage and the output voltage exceed the range, the reference voltage and the output voltage may be in a nonlinear correlation relationship. Therefore, when the output voltage of the parallel power supply is not equal to the preset optimal working voltage, the target reference voltage corresponding to each power supply module when outputting the optimal working voltage can be determined based on the association relationship corresponding to each power supply module; and generating a control signal based on a target reference voltage corresponding to each power module when outputting the optimal working voltage, so that each power module adjusts the respective reference voltage to the target reference voltage corresponding to each power module when outputting the optimal working voltage based on the control signal, for example, when the reference voltage and the output voltage of the power modules are in a linear relationship, when the output voltage of the parallel power supply is detected to be less than the optimal working voltage, the output voltage of each power module can be increased by increasing the reference voltage of each power module until the output voltage of each power module reaches the optimal working voltage. Similarly, when the output voltage of the parallel power supply is detected to be greater than the optimal working voltage, the output voltage of each power supply module can be reduced by reducing the reference voltage of each power supply module until the output voltage of each power supply module reaches the optimal working voltage, so that the output voltage of the parallel power supply can be adjusted to the optimal working voltage of the data processing equipment, and the data processing equipment can reach the optimal working state.
In this embodiment, output voltage information of the parallel power supply and reference voltage information of each power supply module constituting the parallel power supply are acquired, whether the output voltage of the parallel power supply is consistent with a preset optimal operating voltage is determined based on the acquired output voltage information, and if the output voltage of the parallel power supply is not consistent with the preset optimal operating voltage, a control signal is generated based on the reference voltage information of each voltage module, so that each power supply module in the parallel power supply adjusts its own reference voltage based on the control signal, and the optimal operating voltages of its own output voltage domains are consistent. The output voltage of the parallel power supply can be adjusted to the optimal working voltage by adjusting the reference voltage of each power supply module when the output voltage of the parallel power supply is inconsistent with the preset optimal working voltage, so that the aim of adjusting the voltage of the parallel power supply and meeting the power consumption requirement of a load working in the optimal working state is fulfilled.
Further optimization and extension of the above embodiment are provided below.
Fig. 3 is a flowchart of an execution method of step 103 according to an embodiment of the present disclosure, and as shown in fig. 3, step 103 may include the following sub-steps:
and step 1031, based on the current reference voltage of each power module, adjusting the reference voltage of each power module according to preset steps until the adjusted reference voltage of each power module reaches the target reference voltage corresponding to each power module, so as to obtain the reference voltage of each power module in each step.
And 1032, generating control signals respectively based on the reference voltages of the power modules during each step, so that the power modules adjust the respective reference voltages based on the control signals, so that the reference voltages of the power modules gradually reach the respective target reference voltages.
The following description will be given by taking a case where the parallel power supply includes two power supply modules as an example, and the analogy can be repeated when the parallel power supply includes more power supply modules.
Assuming that two power modules are connected in parallel and each power module is set to output 9V voltage in a targeted manner, the reference voltage value of each power module can be adjusted by the voltage regulating module in each power module to realize 9V high-precision output, as shown in FIG. 4, in which V is shown in FIG. 40Representing the output voltage, VrefThe reference voltages are represented by b1, b2, K1 and K2 which are constants, and the reference voltage of the power module 1 at 9V is Vref11The reference voltage of the power module 2 at 9V is Vref21. In the same way, the reference voltage V of the power supply module can be calibrated when the power supply module outputs 10V voltageref12And Vref22。
When the parallel power supply formed by the power supply modules 1 and 2 stably outputs 9V voltage, the reference voltages of the power supply modules 1 and 2 are V respectivelyref11And Vref21At this time, if the output voltage of the parallel power supply is adjusted to 10V, the reference voltages of the power supply modules 1 and 2 need to be adjusted to V respectivelyref12And Vref22At this time, the reference voltages of the power modules 1 and 2 can be respectively regulated to V by a step-by-step voltage regulation methodref12And Vref22And further improve the stability of the parallel power supply in the voltage regulating process. For example, the reference voltage of the power module 1 needs to be changed from V during the voltage regulation processref11Is adjusted to Vref12Using step-wise voltage regulation, e.g. of Vref11To Vref12The voltage is divided into 100 parts or more, so that the step value of each voltage regulation is (10-9)/100 is 0.01V, even if the response speed of the voltage regulation of each power supply module is inconsistent, the output oscillation range is only 0.01V, the influence on the stability of the parallel power supply can be ignored, and the next voltage regulation is carried out after the voltage regulation of the power supply modules is finished and stabilized. Therefore, the voltage regulation of the whole parallel power supply is realized by stepping voltage regulation of each power supply module for many times. The specific step value of the voltage regulation is set according to the requirement, and is not specifically limited herein.
The reference voltage of each power module in the parallel power supply is adjusted in a stepping mode in this embodiment, so that the stability of the parallel power supply can be guaranteed on the premise of realizing the purpose of voltage regulation, the reliability of the power supply is improved, and the parallel power supply is prevented from being damaged due to voltage oscillation.
