Abstract

The embodiment of the invention discloses a multipath server power supply circuit and a power supply control method. The circuit comprises a PSU, a distribution board, a plurality of hot plug modulesand a plurality of power planes. The distribution board is connected with the PSU and the plurality of hot plug modules used for controlling output of PSU voltage through a plurality of hot plug modules, the hot plug modules are correspondingly connected with the power supply plane, and the hot plug modules are used for controlling the output time sequence of the power supply plane, detecting output parameters of the current power supply plane and interrupting output of the current power supply plane when the output parameters are abnormal. According to the invention, a three-level board card,multi-power plane and hot plug protection design is adopted, the output parameter of each power plane is monitored through the respective hot plug module, when the output parameter is abnormal, the output of the current faulty power plane is controlled to be interrupted, the normal work of other power planes is not influenced, the controllability of the power planes is enhanced, and the output power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of server power supply, in particular to a multi-channel server power supply circuit and a power supply control method. Background technique [0002] With the development of science and technology, the application scenarios of servers are becoming more and more diversified, and more flexible and efficient performance requirements are also put forward for power supplies. For the product demand of high power consumption, the reasonable design of digital power supply is the premise of completing the product design. A good power plane allocation will make the whole design process more effective: reduce the difficulty of layout, BMC (Baseboard Management Controller, baseboard management controller), CPLD (Complex Programmable Logic Device, complex programmable logic device) It is easier to control the power conversion chip, and it is easier to Easy to monitor each power supply [0003] In a common server power ...
