The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings; it is to be understood that only some of the structures associated with the present invention are shown in the drawings for convenience of description, not all of the structures.
The server power supply is a power supply used on a server, and most of the current server power supplies are standardized modules, such as Intel CRPS (Power supply design Specification defined by Intel), which define the standard size and the definition of output pins of the server power supply and are beneficial to realizing the general design and batch production of the server power supply.
Originally, the output voltage of the PSU was designed to be 12V, and as the GPU increases, the centralized power supply application and the power supply power increases, the current of the PSU also increases, and the temperature rise of the connector and the line voltage drop are all limited, and in order to overcome the use limit, the PSU with the output voltage of 54V or 48V should be generated. However, there is no difference between the conventional 12V PSU and the conventional 54V or 48V PSU in appearance and pin, and it is easy to connect the wrong PSU to the motherboard, for example, if the conventional 54V or 48V PSU is connected to the 12V motherboard, the devices on the motherboard are damaged due to overvoltage, which is likely to cause serious consequences.
In order to solve the above problems in the prior art, the present invention provides the following technical solutions, which are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a power supply control method according to an embodiment of the present invention is shown, where the power supply control method is applied to a motherboard connected to a PSU.
Specifically, the control method includes:
s11, detecting a first starting signal.
The first power-on signal may be triggered by a user, for example, by pressing a power-on key on a motherboard.
And S12, generating a voltage feedback signal corresponding to the current mainboard type when the triggering of the first starting signal is detected.
In particular, the voltage feedback signal is for transmission to the PSU.
Referring to fig. 2, a flowchart of step S12 in a power control method according to an embodiment of the present invention is shown. Specifically, in step S12, generating a voltage feedback signal corresponding to the current motherboard type includes:
and S121, adjusting a voltage feedback value of the mainboard feedback pin to enable the voltage feedback value to be within a voltage feedback range corresponding to the current mainboard type.
In this embodiment, a CPLD is disposed in the motherboard 10, and the CPLD includes an MOS transistor; the CPLD is connected with a mainboard feedback pin, and the mainboard feedback pin is connected with an adjustable resistor; when the voltage feedback value of the mainboard feedback pin needs to be adjusted, the CPLD changes the voltage feedback value of the mainboard feedback pin through the on-off of the MOS tube and the change of the resistance value of the adjustable resistor.
Specifically, the motherboard feedback pin is a power supply pin (PS _ ON pin) in the motherboard.
For example, when the current motherboard is 12V, the CPLD adjusts the voltage feedback value of the motherboard feedback pin to a value range below 1V; when the current mainboard is 54V or 48V, the voltage feedback value of the mainboard feedback pin is adjusted to be in the numerical range of 1.4-1.6V.
And S122, generating a voltage feedback signal representing the voltage feedback value.
In this step, a voltage feedback signal can be generated due to a change in voltage at the motherboard feedback pin.
Specifically, by changing the resistance value of the adjustable resistor, the voltage feedback value of the motherboard feedback pin is changed, and further, the level value fed back to the PSU by the motherboard is changed, and the level value is used as the voltage feedback signal in the step.
The voltage feedback signal can be used for representing a voltage feedback value within a certain interval, and the voltage feedback signal is used as a basis for judging whether the PSU is started or not. The voltage feedback signal is utilized to reflect the type of the currently accessed mainboard to the PSU, if the currently accessed mainboard is a 12V mainboard, the generated voltage feedback signal is used for representing a voltage feedback value corresponding to the 12V mainboard, and if the currently accessed mainboard is a 54V or 48V mainboard, the generated voltage feedback signal is used for representing a voltage feedback value corresponding to the 54V or 48V mainboard.
For example, when the current motherboard is 12V, the voltage feedback value represented by the generated voltage feedback signal is in a numerical range below 1V; when the current mainboard is 54V or 48V, the voltage feedback value represented by the generated voltage feedback signal is in a numerical range of 1.4-1.6V.
By optimizing the control circuit, the sectional control of the voltage feedback value is realized, and the voltage feedback value of the feedback pin of the mainboard is adaptively adjusted according to different types of mainboards, so that the PSU can be used as a basis for judging whether the computer is started or not according to the voltage feedback signal for representing the voltage feedback value.
Based on the foregoing embodiments, please refer to fig. 3, which is a flowchart of a power supply method of a power supply according to an embodiment of the present invention. The power supply method of the power supply provided by the embodiment is applied to a PSU connected with a motherboard, and includes:
s21, detecting a second starting signal.
It will be appreciated that the second power-on signal may be triggered by the user, for example, by pressing a power-on key on the PSU or on the motherboard.
And S22, receiving a voltage feedback signal from the mainboard when the trigger of the second starting signal is detected.
The PSU is connected with a main board feedback pin, and the main board feedback pin is connected with an adjustable resistor; in addition, a CPLD is arranged in the main board 10, and the CPLD includes an MOS transistor; the CPLD is connected with a mainboard feedback pin; when the voltage feedback value of the mainboard feedback pin needs to be adjusted, the voltage feedback value of the mainboard feedback pin is changed through the on-off of the MOS tube and the change of the resistance value of the adjustable resistor. Specifically, the motherboard feedback pin is a power supply pin (PS _ ON pin) in the motherboard.
For example, when the current motherboard is 12V, the voltage feedback value of the motherboard feedback pin is adjusted to a value range below 1V; when the current mainboard is 54V or 48V, the voltage feedback value of the mainboard feedback pin is adjusted to be in the numerical range of 1.4-1.6V.
Because the voltage on the mainboard feedback pin changes, a voltage feedback signal can be generated. Specifically, by changing the resistance value of the adjustable resistor, the voltage feedback value of the motherboard feedback pin is changed, and further, the level value fed back to the PSU by the motherboard is changed, and the level value is used as the voltage feedback signal in the step.
In this embodiment, the PSU is connected to the motherboard through the ADC interface, and the acquired voltage feedback value of the motherboard feedback pin is a specific value, so that the segmented feedback of the voltage feedback value in different value ranges is implemented.
And S23, judging whether to execute the PSU starting operation or not based on the voltage feedback signal.
Referring to fig. 4, a flowchart of step S23 of a power supply method according to an embodiment of the present invention is shown. Specifically, step S23 includes:
and S231, acquiring a voltage feedback value of the mainboard feedback pin based on the voltage feedback signal.
The mainboard feedback pin is a power supply pin in the mainboard. In this step, the current voltage value of the motherboard feedback pin may be detected through the ADC interface to obtain the voltage feedback value.
The voltage feedback signal can be used for representing a voltage feedback value in a certain interval, and the voltage feedback signal is used as a judgment basis for judging whether the PSU is started or not. By using the voltage feedback signal, the currently accessed mainboard type can be reflected to the PSU.
For example, when the currently connected motherboard is a 12V motherboard, the generated voltage feedback signal is used to represent a voltage feedback value corresponding to the 12V motherboard, and for example, when the current motherboard is a 54V or 48V motherboard, the generated voltage feedback signal is used to represent a voltage feedback value corresponding to the 54V or 48V motherboard. Based on this, the PSU can obtain a corresponding voltage feedback value according to the currently obtained voltage feedback value.
S232, judging whether the voltage feedback value is in a voltage standard range corresponding to the current PSU type; if yes, starting the PSU; if not, the PSU is not started.
Specifically, a corresponding voltage standard range is determined in advance according to the type of the PSU, and the voltage standard range is matched with voltage feedback values of motherboards of the same type.
For example, when the current PSU is 12V, the corresponding voltage standard range matches with the voltage feedback value of the motherboard of 12V, and specifically may be a numerical range below 1V; when the current PSU is 54V or 48V, the corresponding voltage standard range matches with the voltage feedback value of the motherboard of 54V or 48V, and specifically may be a numerical range of 1.4 to 1.6V.
Only when the type of the main board represented by the voltage feedback value obtained by the current PSU is consistent with that of the PSU, the PSU is started, otherwise, the PSU is not started, and therefore the problem of burn-in caused by errors is effectively solved.
Based on the foregoing embodiments, please refer to fig. 5, which is a block diagram of a power control system according to an embodiment of the present invention, including a motherboard 10, where the motherboard 10 is connected to an output terminal of a PSU;
the main board 10 includes:
a first detection unit 11, configured to detect a first power-on signal;
the signal control unit 12 is connected to the first detection unit 11, and configured to generate a voltage feedback signal corresponding to the current type of the motherboard 10 when the first detection unit 11 detects that the first boot signal is triggered, where the voltage feedback signal is used to transmit the voltage feedback signal to the PSU; the voltage feedback signal is used as a basis for judging whether the PSU is started or not.
Optionally, the signal control unit 12 is specifically configured to adjust a voltage feedback value of the motherboard feedback pin, so that the voltage feedback value is within a voltage feedback range corresponding to the current type of the motherboard 10, and thereby generate a voltage feedback signal representing the voltage feedback value.
Fig. 6 is a schematic circuit diagram of a motherboard 10 in a power control system according to an embodiment of the present invention.
In this embodiment, the signal control unit 12 includes a CPLD, the CPLD includes an MOS transistor Q1, a source of the MOS transistor Q1 is connected to the enable terminal PSU _ EN of the PSU, a gate of the MOS transistor Q1 is connected to the enable terminal CPLD _ EN of the CPLD, a drain of the MOS transistor Q1 is connected to an adjustable resistor R1, and the other end of the adjustable resistor R1, which is far away from the MOS transistor Q1, is connected to the enable terminal PSU _ EN of the PSU.
When the resistance value of the adjustable resistor R1 changes, the MOS transistor Q1 pulls down the level inside the motherboard 10, so that the voltage feedback value of the motherboard feedback pin changes.
As an example, when the current motherboard 10 is 12V, the resistance of the adjustable resistor R1 is adjusted to 0 Ω, so that the voltage feedback value of the motherboard feedback pin is adjusted to a value range below 1V; when the current main board 10 is 54V or 48V, the resistance value of the adjustable resistor R1 is adjusted to 7.3-9.4K Ω, and the voltage feedback value of the main board feedback pin is adjusted to be within the numerical range of 1.4-1.6V.
Based on the foregoing embodiments, please refer to fig. 7, which is a block diagram of a power supply system of a power supply according to an embodiment of the present invention. In this embodiment, the power supply system of the power supply includes a PSU20, and the PSU20 is connected to the input terminal of the motherboard 10.
Specifically, the PSU20 includes:
a second detection unit 21, configured to detect a second power-on signal; it will be appreciated that the second power-on signal may be triggered by the user, for example, by pressing a power-on key on the PSU20 or on the motherboard 10;
the receiving unit 22 is connected to the second detecting unit 21, and is configured to receive a voltage feedback signal from the motherboard 10 when the second detecting unit 21 detects that the second boot signal is triggered;
and a judgment execution unit 23, configured to judge whether to execute a PSU boot operation based on the voltage feedback signal.
Further, the judgment execution unit 23 is configured to obtain a voltage feedback value of the motherboard feedback pin based on the voltage feedback signal, and judge whether the voltage feedback value is within a voltage standard range corresponding to the current PSU20 type; if yes, the PSU20 is started; if not, the PSU20 is not powered on.
In this embodiment, the PSU20 is connected to the motherboard 10 through the ADC, so that a voltage feedback value can be obtained by detecting a current voltage value of a motherboard feedback pin, and the voltage feedback value is used as a basis for whether the motherboard is turned on.
The motherboard feedback pin is a power supply pin in the motherboard 10.
Because the voltage on the mainboard feedback pin changes, a voltage feedback signal can be generated. Specifically, by changing the resistance value of the adjustable resistor, the voltage feedback value of the motherboard feedback pin is changed, so that the level value fed back to the PSU20 by the motherboard 10 is changed, and the level value is used as the voltage feedback signal in this step.
Based on this, the voltage feedback signal can be used to represent a voltage feedback value within a certain interval, and the voltage feedback signal is used as a criterion for determining whether the PSU20 is powered on. With the voltage feedback signal, the currently accessed motherboard type can be reflected to the PSU 20.
For example, when the currently connected motherboard 10 is a 12V motherboard, the generated voltage feedback signal is used to represent a voltage feedback value corresponding to the 12V motherboard 10, and for example, when the current motherboard 10 is a 54V or 48V motherboard, the generated voltage feedback signal is used to represent a voltage feedback value corresponding to the 54V or 48V motherboard 10. Based on this, the PSU20 can obtain a corresponding voltage feedback value according to the currently obtained voltage feedback value.
Specifically, a corresponding voltage standard range is determined in advance according to the type of the PSU20, and the voltage standard range is matched with the voltage feedback values of the same type of main boards.
For example, when the current PSU20 is 12V, the corresponding voltage standard range matches with the voltage feedback value of the main board of 12V, and specifically may be a numerical range below 1V; when the current PSU20 is 54V or 48V, the corresponding voltage standard range matches with the voltage feedback value of the motherboard of 54V or 48V, and may specifically be a numerical range of 1.4 to 1.6V.
For example, please refer to table 1 below, which shows the detected voltage feedback value and the corresponding power-on condition of the PSU for different PSU power types.
TABLE 1
Therefore, the PSU20 is only started when the type of the motherboard 10 represented by the voltage feedback value obtained by the PSU20 is consistent with that of the PSU20, otherwise, the PSU20 is not started, thereby effectively preventing the burn-in problem caused by errors.
