Abstract

The invention provides a decoupling device and decoupling method of a server power cable. A power supply copper foil bonding pad region and a ground copper plate bonding pad region are arranged in thedecoupling device C, a power supply copper foil bonding pad hollow region is arranged at a position, corresponding to the power supply copper foil bonding pad, of the front surface of the decouplingdevice C, and a ground copper plate bonding pad hollow region is arranged at a position, corresponding to the ground copper plate bonding region, of the front surface of the decoupling device C. By the decoupling device of the server power cable, the parasitic inductance brought by the cable can be prevented, the influence of the parasitic inductance is reduced, and the voltage fluctuation of electric equipment GPU is reduced; and the device can be arranged onto the power cable, different types of decoupling capacitors can be welded according to design demands, so that the influence of the parasitic inductance of the cable is reduced, and the power stability of the GPU is improved.

Description

technical field [0001] The invention relates to the field of server power supplies, in particular to a server power supply cable decoupling device and a decoupling method. Background technique [0002] With the development of cloud computing and big data, the demand for servers and storage is increasing. In the design of servers and storage, in order to meet the different needs of customers, the functions of servers are becoming more and more powerful. The demand for capabilities is also increasing. In this case, GPU series servers are gradually developed and used more and more. [0003] GPU requires a lot of current, which brings new challenges to the design of the power supply. How to design a power supply that meets the requirements of the GPU in a limited space and cost has become one of the keys to the success of GPU server design. [0004] Connection Diagram of Traditional Power Cables and Connectors figure 1 As shown, it can be seen that after connecting the cable, ...
