Embodiment 1

[0038] see figure 1 , figure 1 It is a schematic flowchart of a method for optimizing server power provided by the embodiment of the present application. Depend on figure 1 It can be seen that the method for optimizing server power in this embodiment mainly includes the following processes:

[0039] S1: Gather the output current of the LLC stage.

[0040] The server power supply in this embodiment includes a PFC stage and an LLC stage, and the output end of the PFC stage is connected to the input end of the LLC stage.

[0041] Generally, the output current of the LLC stage includes four situations: no-load, light load, half-load and full load. Suppose the output current of the LLC stage is I out , when I out =0, it is called no load; when I out =I max , that is, the output current of the LLC stage reaches the rated operating current I max When it is called full load; when I out =0.5*I max When , it is called half load; when 0out =0.5*I max , called light load.

Embodiment 2

[0058] exist Figure 1-Figure 3 On the basis of the illustrated embodiment see Figure 4 , Figure 4 It is a schematic structural diagram of a system for optimizing server power provided by an embodiment of the present application. Depend on Figure 4 It can be seen that the system for optimizing server power in this embodiment mainly includes three parts: an output current collection module, a to-be-output voltage calculation module, and an update module.

[0059] Wherein, the output current collecting module is used for collecting the output current of the LLC stage. The output voltage calculation module is used to use the formula Vin according to the output current Ref =K*I out +380, calculate the output voltage of the PFC stage, where 380 is the PFC reference voltage, I out is the output current of the LLC stage, Vin Ref is the output voltage of the PFC stage, and K is the regulation coefficient. The update module is used to update the current output voltage of the...

Abstract

The invention discloses a method and a system for optimizing a server power supply. The method comprises the following steps: acquiring LLC-level output current; according to the output current, utilizing a formula VinRef = K * Iout + 380 to calculate the to-be-output voltage of the PFC level; and updating the current output voltage of the PFC stage according to the to-be-output voltage. The system comprises an output current acquisition module, a to-be-output voltage calculation module and an updating module. Through the application, the efficiency of the LLC loop can be effectively improved,and the overall efficiency of the server power supply can be greatly improved under the condition of ensuring that the holdump time is improved.

Description

technical field [0001] The present application relates to the technical field of server power supplies, in particular to a method and system for optimizing server power supplies. Background technique [0002] The server power supply is usually an AC / DC power supply, and the AC / DC (Alternating Current / Direct Current, alternating current / direct current) power supply is used to convert the mains power into a 12V power supply for use by the server. At present, the AC / DC power supply design in the industry usually adopts PFC (Power Factor Correction, power factor correction) + LLC (LLC resonant converter, LLC resonant converter) two-stage structure. Electricity is converted to higher DC power; the LLC stage converts the higher DC power to the low-voltage DC power required by server systems. With the continuous improvement of the performance requirements of the server system on the AC / DC power supply, how to improve the holdup time (holding time) to optimize the server power supp...
