Description

Starting control method of server power supply and server power supply control system

technical field

The invention relates to the field of server power supplies, in particular to a server power startup control method and a server power control system.

Background technique

In order to meet the power requirements of the server system for the server power supply while increasing the space occupied by the server power supply, it is usually possible to increase the operating frequency of the server power supply and reduce the volume of passive components such as inductors and capacitors. However, due to the limitation of the control chip and switching devices, the operating frequency of the server power supply is generally below 300kHz. When the operating frequency exceeds 500kHz, it is difficult for the control chip in the traditional server power supply architecture to perform closed-loop control, and the adjustable DC transformer ( Regulated DC Transformer, RDCX) Most of the energy transfer works in the DC transformer mode and does not need to be controlled. Therefore, the adjustable DC transformer can control the overall energy by controlling a small part of the energy.

In order to reduce switching losses, most of the current adjustable DC transformer solutions use low-voltage gallium nitride devices, and then use multiple modules in series and parallel for low-voltage adjustable DC transformer modules. However, since the current server power supply only judges the voltage at both ends of the main capacitor connected in parallel to the input terminal of the server power supply to control the working state of the server power supply, if the multi-adjustable DC transformer module is directly introduced into the server power supply, a certain adjustable DC transformer module will appear A fault has occurred, but the voltage across the main capacitor still meets the conditions for starting the power supply, resulting in abnormal operation of the server power supply, and even damage to the switching device.

After the electromagnetic interference filter circuit and the power factor correction circuit, a main body capacitor, ie BULK capacitor (C _BUIK ), is connected in parallel to the input end of the server power supply to ensure the stability of the output voltage of the server power supply. In related technologies, the signal processor usually collects the voltage across the main body capacitor to determine whether the input voltage of the server power supply is within a normal range, and starts the server power supply when the voltage across the main body capacitor is within a normal range. However, under the circuit design of multiple adjustable DC transformer modules as shown in Figure 2, due to differences in hardware circuits, the voltage of each adjustable DC transformer module is not completely divided; in addition, in some fault situations, some One or more adjustable DC transformer modules have failed, but at this time the voltage of the faulty adjustable DC transformer module will be distributed to other normal adjustable DC transformer modules, and the voltage at both ends of the main capacitor is still within the normal range. This leads to the fact that the voltage at both ends of the main capacitor cannot truly reflect the internal working status of the server power supply, and will transmit a wrong start signal, which will cause the server power supply and other normal adjustable DC transformer modules to work abnormally, and even cause switching devices to fail. damage.

Based on this, the present invention provides a start-up control method of the server power supply, which takes into account the voltage at both ends of the capacitor connected in parallel with the input terminal of each adjustable DC transformer module, comprehensively considers the input voltage of the server power supply and each adjustable The input voltage of the DC transformer module. When the input voltage of the server power supply and the input voltage of each adjustable DC transformer module are within the normal range, the server power supply will be started, so as to avoid the wrong startup of the server power supply and protect the internal power supply of the server power supply. device.

Specifically, the first voltage information of the server power supply is obtained; the second voltage information corresponding to each adjustable DC transformer module in the plurality of adjustable DC transformer modules is respectively obtained to obtain a plurality of second voltage information; based on the first voltage information and Multiple pieces of second voltage information to control the startup and shutdown of the server power supply.

In the embodiment of the present invention, the start-up control method of the server power supply is not only applicable to the server power supply using multiple adjustable DC transformer modules, but also applicable to any other circuit design using multiple adjustable DC transformer modules.

As an optional implementation, the server power supply start control method can be integrated in the signal processor in the form of a program or software, a signal processor is set in the server power supply, and the server power supply is started by the signal processor control.

Step S301, acquiring a first voltage of a server power supply.

In the embodiment of the present invention, the first voltage is the input voltage value of the server power supply, and is used to determine whether the input voltage of the server power supply is normal, that is, to determine whether the overall working voltage inside the server power supply is normal.

As an optional implementation manner, the input end of each adjustable DC transformer module among the multiple adjustable DC transformer modules is respectively connected in parallel with a second capacitor, and the second voltage is the collected voltage value at both ends of the second capacitor.

As an optional implementation, since multiple adjustable DC transformer modules use the same adjustable DC transformer to share the input voltage of the server power supply equally, the second capacitor connected in parallel to the input end of each adjustable DC transformer module Capacitors of the same type can be used.

As an optional implementation manner, the second capacitor can be selected according to the working voltage and maximum voltage of the adjustable DC transformer module.

Step S303, based on the first voltage, a plurality of second voltages and a preset voltage range, controlling the power supply of the server to be started and shut down.

In the embodiment of the present invention, in order to avoid that one or more adjustable DC transformer modules have failed, but the voltage of the faulty adjustable DC transformer module is distributed to other normal adjustable DC transformer modules, the voltage at both ends of the main body capacitor If the voltage is still within the normal range, introduce the input voltage of each adjustable DC transformer module, that is, the second voltage, and combine the first voltage and the second voltage to comprehensively determine whether each module inside the server power supply is in a normal state, and based on This controls the power on and off of the server.

As an optional implementation manner, when the server power supply is connected to a high-voltage input voltage, whether to start the server power supply is determined through a start-up control method of the server power supply. After the server power supply is started, the first voltage and the second voltage are obtained in real time, and based on this, it is determined whether each module and device inside the server power supply is working normally. When a module or device is abnormal or faulty, the server power supply is turned off.

As an optional implementation, when it is detected that the server power supply suddenly loses power, or there is a demand for the working voltage of the server power supply in related equipment or devices connected to the server power supply, the server power supply startup control method is used to control the server power supply. The first voltage and the second voltage are detected, and it is judged whether each module and device inside the server power supply is working normally, and when a certain module or device is abnormal or faulty, the server power supply is turned off.

The start-up control method of the server power supply provided in this embodiment judges the working state of the server power supply by integrating the voltage information of the server power supply and the voltage of each adjustable DC transformer module, thereby controlling the server power supply and avoiding errors of the server power supply Start to protect each device in the server power supply.

According to an embodiment of the present invention, an embodiment of a method for starting and controlling a server power supply is provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

In this embodiment, a server power supply start-up control method is provided, which can be used in the above-mentioned circuit design using multiple adjustable DC transformer modules, etc. FIG. 4 shows another server power supply start-up control according to an embodiment of the present invention The flowchart of the method, as shown in Figure 4, the process includes the following steps:

Step S401, acquiring a first voltage of a server power supply. For details, refer to step S301 in the embodiment shown in FIG. 3 , and details are not repeated here.

Step S402, acquiring the second voltage of each adjustable DC transformer module respectively. For details, please refer to step S302 in the embodiment shown in FIG. 3 , which will not be repeated here.

Step S403, based on the first voltage, a plurality of second voltages and a preset voltage range, control the start and stop of the power supply of the server.

In the embodiment of the present invention, the first voltage and the second voltage are respectively provided with corresponding preset voltage ranges; the preset voltage range corresponding to the first voltage is the first preset voltage range, and the preset voltage range corresponding to the second voltage is The second preset voltage range. The first preset voltage range is a preset voltage range capable of ensuring normal operation of the server power supply, and the second preset voltage range is a preset voltage range capable of ensuring normal operation of each device in the adjustable DC transformer module.

Specifically, the above step S403 includes:

Step S4031, when the first voltage is within the first preset voltage range, and the plurality of second voltages are all within the second preset voltage range, determine the power start signal as the first preset value, so as to control the power supply of the server start up.

In the embodiment of the present invention, when the first voltage is within the first preset voltage range, and multiple second voltages are all within the second preset voltage range, it means that all devices inside the server power supply can work normally at this time , there is no failure, and the power supply of the server can be started normally at this time, so the power start signal is determined as the first preset value.

As an optional implementation manner, in order to determine whether to start the server power from the power start signal, a first preset value is preset, and when the power start signal is the first preset value, it indicates that the server power can be started.

As an optional implementation, the first preset value can be set to "TRUE", or any value in binary or hexadecimal that can be distinguished from the power start signal corresponding to not starting or turning off the power of the server The numbers or symbols, for example, binary numbers, the first preset value is set to "1".

As an optional implementation, the first preset voltage range can be set according to the specifications of the first capacitor connected in parallel to the input end of the server power supply, and the second preset voltage range can be set according to the specification of the first capacitor connected in parallel to the input end of the adjustable DC transformer module. The specification of the second capacitor is set. The specifications of the first capacitor and the second capacitor can be set according to the specification of the adjustable DC transformer module, and the specification of the adjustable DC transformer module can be set according to the output voltage value of the server power supply. For example, if the server power supply is required to output a voltage of 400V, and there are four adjustable DC transformer modules inside the server power supply, then the normal working voltage of each adjustable DC transformer module is 100V. For the second capacitor required by the DC transformer module, considering redundant settings and avoiding resource waste, the second capacitor with a maximum voltage of 120V can be selected, and correspondingly, the first capacitor with a maximum voltage of 440V can be selected. Therefore, based on the output voltage value of the server power supply and the settings of the adjustable DC transformer modules inside the server power supply, the appropriate first capacitor and the second capacitor are selected, thereby determining the specifications of the first capacitor and the second capacitor.

As an optional implementation, two signal processors can be set inside the server power supply, namely the first signal processor and the second signal processor, and the first signal processor is mainly responsible for detecting and obtaining the first voltage of the server power supply and the second voltage of the adjustable DC transformer module, and determine the power start signal based on the first voltage and the second voltage; the second signal processor determines whether to control the power start of the server based on the power start signal determined by the first signal processor .

As an optional implementation, there may only be one signal processor inside the server power supply, and one signal processor can obtain the first voltage of the server power supply and the second voltage of the adjustable DC transformer module to determine the power supply start signal. All steps to determine if you want to control server power up.

As an optional implementation, in practical applications, unless a sudden failure occurs, there is an abnormal working state between the normal working state and the faulty state of the server power supply and the adjustable DC transformer module. That is, the server power supply and the adjustable DC transformer module will not switch directly from the normal working state to the faulty state, but will first enter the abnormal working state from the normal working state, and can still work in the abnormal working state, but at this time the server power supply may be An abnormality has already occurred in the DC regulating transformer module, and if the related abnormality is not handled, it may cause the server power supply and the adjustable DC transformer module to further malfunction and fail to work.

As an optional implementation, the first preset voltage range corresponding to the first voltage and the second preset voltage range corresponding to the second voltage may not include the voltage range under the abnormal working state, that is, in the first Under the preset voltage range and the second preset voltage range, the server power supply and the adjustable DC transformer module only work in the normal state. Correspondingly, the server power supply is only started when the adjustable DC transformer The server power supply can still work in the working state, so as to prevent the user from being unable to respond to the abnormality of the server power supply and the adjustable DC transformer module in time, causing the components in the server power supply to fail.

As an optional implementation, the first preset voltage range corresponding to the first voltage and the second preset voltage range corresponding to the second voltage may include voltage ranges under abnormal working conditions, that is, in the first preset In the voltage range and the second preset voltage range, the server power supply and the adjustable DC transformer module may also work in an abnormal state. Correspondingly, as long as the adjustable DC transformer module can work, the server power supply is started. At this time, the abnormality alarm information can be set to inform the user that the server power supply or the adjustable DC transformer module is abnormal, so as to timely investigate the abnormal situation and avoid the failure of the components in the server power supply.

As an optional implementation manner, for the first voltage and the second voltage, their abnormal states may include an overvoltage abnormal state and an undervoltage abnormal state. Overvoltage indicates that the voltage of the component corresponding to the voltage value exceeds the maximum voltage that the component can withstand; undervoltage indicates that the voltage of the component corresponding to the voltage value is lower than the minimum voltage required for the component to work. Correspondingly, the abnormal state of overvoltage indicates that the voltage value exceeds the normal voltage range of the component, but has not yet reached the maximum voltage that the component can withstand; the abnormal state of undervoltage indicates that the voltage value is lower than the normal voltage range of the component , but still above the minimum voltage required for the part to operate. Based on this, the abnormal alarm information can be set to include undervoltage alarm information and overvoltage alarm information, and when a corresponding abnormality occurs, the user is prompted to check the abnormal situation in time.

As an optional implementation manner, the above step S403 may also include:

Step S4032, when the first voltage is lower than the first low-voltage threshold, or when the second voltage among the plurality of second voltages is lower than the second low-voltage threshold, an undervoltage warning message is generated.

In the embodiment of the present invention, the first low voltage threshold is within a first preset voltage range, and the second low voltage threshold is within a second preset voltage range. Specifically, the voltage interval from the minimum voltage value of the first preset voltage range to the first low-voltage threshold is the undervoltage abnormal voltage range of the first voltage. In this abnormal undervoltage voltage range, the server power supply is undervoltage Risk: The voltage interval from the minimum voltage value of the second preset voltage range to the second low-voltage threshold is the undervoltage abnormal voltage range of the second voltage. In this abnormal undervoltage voltage range, the adjustable DC transformer module exists risk of undervoltage.

As an optional implementation manner, the first low voltage threshold may be set according to the specification of the first capacitor, and the second low voltage threshold may be set according to the specification of the second capacitor. For example, if the rated voltage of the second capacitor is 100V, the normal operating voltage range is 90V to 110V, the maximum operating voltage is 120V, and the minimum operating voltage is 80V, then the second preset voltage range is 80V to 120V, and the second low voltage threshold is 90V, and the voltage range from 80V to 90V is the undervoltage abnormal voltage range of the second voltage.

In the embodiment of the present invention, the undervoltage alarm signal is used to remind the user that the power supply of the server has a risk of undervoltage, and if it is not checked as soon as possible, undervoltage may occur and cause the power supply of the server to be shut down.

Therefore, when the voltage information of the adjustable DC transformer module among the multiple adjustable DC transformer modules is about to fall below the normal voltage range, an alarm is issued to inform the user that there is a risk of undervoltage in the server power supply, so as to timely investigate the abnormal situation. Avoid device failure in the server power supply.

As an optional implementation manner, the above step S403 may also include:

Step S4033, when the first voltage is higher than the first high voltage threshold, or when the second voltage among the plurality of second voltages is higher than the second high voltage threshold, an overvoltage warning message is generated.

In the embodiment of the present invention, the first high voltage threshold is within a first preset voltage range, and the second high voltage threshold is within a second preset voltage range. Specifically, the voltage interval from the first high voltage threshold to the maximum voltage value of the first preset voltage range is the abnormal overvoltage voltage range of the first voltage, and in this abnormal overvoltage voltage range, the server power supply has an overvoltage Risk: The voltage interval from the second high voltage threshold to the maximum voltage value of the second preset voltage range is the overvoltage abnormal voltage range of the second voltage. In this overvoltage abnormal voltage range, the adjustable DC transformer module exists Risk of overvoltage.

As an optional implementation manner, the first high voltage threshold may be set according to the specification of the first capacitor, and the second high voltage threshold may be set according to the specification of the second capacitor. For example, if the rated voltage of the second capacitor is 100V, the normal operating voltage range is 90V to 110V, the maximum operating voltage is 120V, and the minimum operating voltage is 80V, then the second preset voltage range is 80V to 120V, and the second high voltage threshold is 110V, and the voltage range from 110V to 120V is the overvoltage abnormal voltage range of the second voltage.

In the embodiment of the present invention, the overvoltage alarm signal is used to remind the user that there is an overvoltage risk in the server power supply, and the internal components of the server power supply may fail. , It will also cause the normal components inside the server power supply to also malfunction.

In this way, when the voltage information of the adjustable DC transformer module among the multiple adjustable DC transformer modules is about to be higher than the normal voltage range, an alarm is issued to inform the user that there is an overvoltage risk in the server power supply, so as to timely check the abnormal situation and avoid A device in the server power supply has malfunctioned.

The starting control method of the server power supply in this embodiment starts the server power supply only when the voltage information of the server power supply and the voltage information of each adjustable DC transformer module meet the starting conditions, and it is determined that each module in the server power supply can work normally The power supply of the server is turned on under the condition of the power supply of the server, so as to ensure that the power supply of the server can work normally.

When the first voltage is not within the first preset voltage range, or the second voltage among multiple second voltages is not within the second preset voltage range, it indicates that there is a device failure inside the server power supply at this time, and it cannot be started at this time. Otherwise, other normal devices will also fail, so the power start signal is determined as the second preset value.

As an optional implementation, in order to determine whether to start the server power from the power start signal, a second preset value is preset, and when the power start signal is the second preset value, it indicates that the server power cannot be started, or The server needs to be powered off, so controls the server power off or does not power on the server.

As an optional implementation, corresponding to the first preset value set to "TRUE", the second preset value can be set to "FALSE". Similarly, any binary or hexadecimal value can also be used.

Based on the output voltage value of the server power supply and the settings of the adjustable DC transformer modules inside the server power supply, the appropriate first capacitor and the second capacitor are selected, thereby determining the specifications of the first capacitor and the second capacitor.

As an optional implementation, two signal processors can be set inside the server power supply, namely the first signal processor and the second signal processor, and the first signal processor is mainly responsible for detecting and obtaining the first voltage of the server power supply and the second voltage of the adjustable DC transformer module, and determine the power start signal based on the first voltage and the second voltage; the second signal processor determines whether to control the power start of the server based on the power start signal determined by the first signal processor .
