Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a power supply control method of a server according to an embodiment of the present invention. The method can comprise the following steps:
step 101: and acquiring load state information of the DC/DC power supply in the server.
The DC/DC power supply in this step may convert the DC power output by the AC/DC power supply into DC power with a corresponding voltage to power the connected load. The load state information in this step may be state information of a load powered by the DC/DC power supply, that is, the load state information may represent a state of the load powered by the DC/DC power supply.
It is understood that the purpose of this step may be to determine the state of the load powered by the DC/DC power source (such as a light load state and a full load state) by obtaining the load state information of the DC/DC power source in the server, i.e. the state of the energy delivered by the DC/DC power source required by the load.
Specifically, the specific content of the load status information in this step may be set by a designer according to a practical scenario and a user requirement, for example, the load status information may be current information for supplying power to a load from a DC/DC power supply. The present embodiment is not limited in any way as long as the processor can determine the state of the load powered by the DC/DC power supply according to the acquired load state information.
Correspondingly, the specific number and device type of the DC/DC power supplies in this step may be set by the user according to practical scenarios and user requirements, as long as it is ensured that each DC/DC power supply can convert the voltage output by the AC/DC power supply into a corresponding voltage to supply power to the connected load, which is not limited in this embodiment.
It should be noted that, as to the specific manner in which the processor acquires the load state information of the DC/DC power supply in the server in this step, the specific manner may be set by a designer according to a usage scenario and a user requirement, for example, the processor may receive the load state information acquired and sent by a BMC (Baseboard Management Controller) in the server; as shown in fig. 2, the system BMC may be connected to a load, collect load status information, and send the collected load status information to an AC power source (i.e., an AC/DC power source), so that a processor operating a voltage regulation system in the AC power source may obtain the load status information and correspondingly regulate a voltage output from the AC power source to the DC power source (i.e., the DC/DC power source). The present embodiment does not limit this as long as the processor can acquire the load status information.
Step 102: determining a reference output voltage of the AC/DC power supply according to the load state information; wherein, the output end of the AC/DC power supply is connected with the input end of the DC/DC power supply.
It is understood that the purpose of this step may be to enable the processor to adjust the input voltage of the DC/DC power supply by determining the reference output voltage of the AC/DC power supply using the load status information, thereby adjusting the voltage value of the output voltage of the AC/DC power supply using the reference output voltage. Because the DC/DC power supply generally adopts a BUCK circuit, the input/output characteristics according to BUCK are Vo ═ Vin × D (Vo: output voltage, Vin: input voltage, D: PWM duty cycle); it can be known that when Vin is much larger than Vo, the PWM duty cycle is very small, and the energy transferred to the load by the BUCK voltage reduction circuit can be divided into two parts, one part is directly transferred, and the efficiency is 1; the other part is transmitted to the load through electromagnetic conversion, and the energy of the part is lost. When the duty ratio is small, the energy transferred to the load by electromagnetic conversion accounts for a large proportion, resulting in an increase in the DC/DC power supply loss. Therefore, in the embodiment, the output voltage of the AC/DC power supply is adjusted by using the determined reference output voltage, so that the conversion efficiency of the DC/DC power supply can be improved under a certain load, and the system energy saving is facilitated.
Specifically, the specific manner in which the processor determines the reference output voltage of the AC/DC power supply according to the load state information in this step may be set by a designer, for example, the processor may determine the output current of the AC/DC power supply according to the load state information; determining a reference output voltage according to the output current; that is, the processor may first determine the output current of the AC/DC power supply at the previous time by using the obtained load status information of the DC/DC power supply at the previous time; and determining the reference output voltage required by adjusting the output voltage of the AC/DC power supply at the current moment by using the output current of the AC/DC power supply at the previous moment. The processor may also determine the output power of the AC/DC power supply according to the load status information, and then determine the reference output voltage according to the output power. The present embodiment is not limited in any way as long as the processor can determine the reference output voltage of the AC/DC power supply using the load status information.
Correspondingly, the present embodiment is not limited to the above-mentioned device for determining the reference output voltage according to the output currentIn a body mode, e.g. the processor can directly pass Vref ═ Vmin+ I × K, calculating a reference output voltage; wherein Vref is the reference output voltage, VminThe minimum output voltage is preset, I is the output current, and K is the preset current coefficient. The processor may also determine whether the output current is less than a minimum current threshold (i.e., V)minCorresponding current values); if less than the minimum current threshold, V is setminAs a reference output voltage; if not, judging that the output current is larger than the maximum current threshold (namely V)maxCorresponding current values); if the maximum current is greater than the maximum current threshold, the maximum output voltage (i.e., V) is presetmax) As a reference output voltage; if the current is not greater than the maximum current threshold, the reference output voltage can be calculated by Vref-Vmin + I × K. For example, when Vmin is 6V and Vmax is 12V, the BMC detects that the system is in a light load state, that is, when the output current is smaller than the minimum current threshold, the output of the AC/DC power supply can be automatically adjusted to 6V from 12V, which starts the default output voltage, and the DC/DC power supply performs the conversion of each voltage on the basis of 6V, so as to meet the low-power output requirement; when the BMC detects a state when a system load rises, the AC power supply outputs voltage from 6V to 12V gradually, linear regulation is achieved, and the DC/DC power supply can convert each voltage on the basis of 12V so as to meet the requirement of high-power output.
It should be noted that, this embodiment is exemplified by the output voltage adjustment of one AC/DC power supply in the server, and the output voltage adjustment of other AC/DC power supplies in the server may be implemented in the same or similar manner as the method provided in this embodiment, that is, each AC/DC power supply may adjust its respective output voltage according to the load state information corresponding to the DC/DC power supply that is output by its respective power supply.
Step 103: and controlling the AC/DC power supply to supply power to the DC/DC power supply according to the reference output voltage.
It will be appreciated that the purpose of this step may be to enable the processor to automatically adjust the output voltage of the AC/DC power supply by controlling the AC/DC power supply to power the DC/DC power supply at a reference output voltage.
Specifically, the embodiment is exemplified by the processor directly adjusting the output voltage of the AC/DC power supply to the reference output voltage; the processor may also determine whether an absolute value of a difference between the reference output voltage and the target reference output voltage is less than a voltage adjustment threshold; if so, controlling the AC/DC power supply to supply power to the DC/DC power supply according to the target reference output voltage; if not, controlling the AC/DC power supply to supply power to the DC/DC power supply according to the reference output voltage; the target reference output voltage is a reference output voltage of the current AC/DC power supply supplying power to the DC/DC power supply, that is, an output voltage of the current AC/DC power supply when the output voltage of the current AC/DC power supply is not adjusted, that is, an output voltage of the current AC/DC power supply corresponding to the load state information used when the reference output voltage is determined.
Correspondingly, the processor can determine the variation condition of the load by judging whether the absolute value of the difference between the reference output voltage and the target reference output voltage is smaller than the voltage adjustment threshold, so that when the absolute value is smaller than the voltage adjustment threshold, namely the load slightly varies, the output voltage of the AC/DC power supply is controlled to maintain the original state, and the output voltage of the AC/DC power supply is prevented from fluctuating up and down; the output voltage of the AC/DC power supply is regulated when the voltage regulation threshold is not less, i.e., the load change is significant. As shown in fig. 2, the processor may also determine the variation condition of the load by judging whether the absolute value of the difference between the currently determined output current and the output current determined at the previous time is smaller than the current adjustment threshold when determining the output current of the AC/DC power supply, that is, when the absolute value of the difference is smaller than the current adjustment threshold, not calculate the reference output voltage or use the reference output voltage of the current AC/DC power supply supplying power to the DC/DC power supply as the currently determined reference output voltage; when the reference output voltage is not less than the current regulation threshold, the reference output voltage can be determined by Vref-6 + I K.
In the embodiment of the invention, the reference output voltage of the AC/DC power supply is determined according to the load state information of the DC/DC power supply, and the input voltage of the DC/DC power supply can be adjusted according to the load state of the DC/DC power supply, so that the conversion efficiency of the DC/DC power supply is improved on the basis of meeting the power output requirement, and the service life of the DC/DC power supply is prolonged.
