Problems solved by technology

[0003] The disadvantage of the prior art is: the power bus Busbar of the whole cabinet bears too much transmission current (for example, more than 600A), and it is difficult to design. In order to reduce the loss, it is necessary to increase the cross-sectional area of ​​the power bus, but the designed cross-sectional area is too large It will not only increase the loss of voltage on the power bus, but also affect the heat dissipation wind resistance of the whole cabinet, thus affecting the heat dissipation of the whole cabinet

Abstract

The invention provides a machine cabinet power supply system which comprises at least one alternating-current / direct-current conversion module, a power bus, a plurality of direct-current / direct-current conversion modules and a plurality of servers. The alternating-current / direct-current conversion module is used for converting an input alternating current into a direct current with a first voltage. The power bus is connected with the at least one alternating-current / direct-current conversion module and used for collecting, distributing and transmitting the direct current with the first voltage. The direct-current / direct-current conversion modules are connected with the power bus and used for converting the direct current with the first voltage from the power bus into a direct current with a second voltage, wherein the first voltage is larger than the second voltage. Each direct-current / direct-current conversion module supplies power to one server. According to the machine cabinet power supply system, the transmission current and the sectional area of the power bus is reduced, the loss is reduced, the power use efficiency is improved, and heat dissipation of the machine cabinet is facilitated.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply system for a cabinet. Background technique [0002] At present, most of the power supply schemes for the entire cabinet use a centralized power supply to output 12V for power supply, and then provide the centralized power supply output 12V to a common power bus to supply power to each node (such as a server). According to the existing power supply of the whole cabinet and according to the conditions of the nodes receiving power, the public power bus needs to bear a large current, even more than 600A. [0003] The disadvantage of the prior art is: the power bus Busbar of the whole cabinet bears too much transmission current (for example, more than 600A), and it is difficult to design. In order to reduce the loss, it is necessary to increase the cross-sectional area of ​​the power bus, but the designed cross-sectional area is too large It will not only increase...
