Description

A power supply with modular design

technical field

The utility model relates to the technical field of computer server power supplies, in particular to a modular design power supply structure.

Background technique

The power supply used in the server field is mainly switching power supply. The power supply is a basic part of driving the server system. Servers with different functions and performances have different requirements for various electrical indicators of the power supply, such as: power of the power supply, ripple index of the power supply, whether the power supply has PMBUS function, etc. Requirements.

As shown in Figure 1, the traditional server switching power supply is integrated on a single PCB board, which can be divided into functions: EMI, rectification circuit, filter circuit, switching conversion circuit, auxiliary power supply circuit, control circuit, protection circuits and many other links. In this way, if new requirements are added to some functional parts of the power supply, the entire PCB of the power supply has to be modified accordingly, which makes it difficult to guarantee further upgrades to the power supply. For example: according to the PMBUS function of the power supply, the realization of different versions of the PMBUS function requires different hardware circuits to support. For example: the current SSI power supply PMBUS 1.1 is upgraded to PMBUS1.2 on this basis. In addition to upgrading the software part, it is also necessary to design the entire power supply hardware circuit. Therefore, switching from version 1.1 to version 1.2 is difficult to achieve with partial design modifications on the basis of the existing version 1.1.
