Server power supply and power supply method

Abstract

The invention provides a server power supply and a power supply method, the power supply voltage comprises a voltage conversion module, a controller and a plurality of step-down circuits, the voltageconversion module is connected in series between a PSU power supply and a mainboard, and the output voltage of the PSU power supply is boosted; the main board is connected with a plurality of voltagereduction branches, and voltage reduction circuits are arranged on the real-time voltage reduction branches; the output end of the voltage reduction branch is connected with a load; the input end of the controller is connected with the output end of the main board and the output end of the voltage reduction branch. The output end of the controller is connected with the voltage conversion module and the voltage reduction circuit. According to the invention, the problem of a mainboard through-flow bottleneck can be solved, and the loading capacity of the server is greatly improved; and meanwhile, high voltage is directly converted into electricity required by the load, so that the conversion efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a server power supply and a power supply method. Background technique [0002] With the development of cloud computing applications, informatization has gradually covered all fields of society. People's daily work and life are more and more communicated through the network, and the amount of network data is also increasing. At the same time, the configurations that need to be matched with the server system are also increasing, resulting in a continuous increase in the total power of the system itself. [0003] With the continuous increase of system power, including the increasing power consumption of CPU, memory, GPU, etc., the load of server power supply becomes larger and larger, so the load capacity of server power supply becomes more and more important, and Since the overall size of the server cannot be increased with the increase of power consumption, the power...

AI Technical Summary

Problems solved by technology

If the back-end load is too large, it will cause a very large current required by 12V, that is to say, the current from the PSU to the load terminal will be very large

On the one hand, the high current makes the conversion efficiency low. On the other hand, the copper foil size of the motherboard PCB is limited, which leads to the limited 12V current that the PCB can pass through, which eventually leads to the bottleneck of server power increase.
