Universal power supply system

Abstract

The invention provides a universal power supply system. The universal power supply system comprises a backplane module, more than one DC power module boards, and a plurality of AC / DC power supply units, wherein each DC power module board or AC / DC power supply unit with the same external dimension further comprises a specification setting circuit; when the DC power module board or AC / DC power supply unit is plugged onto the backplane module, the specification identifying signal end of the DC power module board or AC / DC power supply unit can output an identifying signal to a monitoring circuit of the backplane module; a specification comparison table is created in the monitoring circuit, so that the model and specification of the DC power module board or AC / DC power supply unit plugged onto the backplane can be identified by comparing the received identifying signal with the specification comparison table; the current critical value of the DC power module board or the power critical value of each AC / DC power supply unit can be automatically set to serve as a monitoring point of overcurrent or overpower. Therefore, the universal power supply system does not require designing different backplane modules for the different DC power module boards or the different AC / DC power supply units which are adopted by the invention.

Description

technical field [0001] The invention relates to a power supply system, especially a power supply system for industrial computers or servers. Background technique [0002] General industrial computers or servers must operate for a long time, so a high-power power supply system or a power supply system with backup power is required, and because the power requirements of industrial computers or servers produced by each computer factory are different, so General power supply system manufacturers provide a modular power supply system 50 in response to orders for different power specifications, please refer to Figure 9 and Figure 10 shown, which includes: [0003] A casing 51 includes two opposite side openings; [0004] A backplane module 52 is fixed to the opening on one side of the casing 51, which includes a plurality of DC power supply and communication ports 521 and a monitoring circuit 522; wherein each DC power supply and communication port 521 includes a power output ...

AI Technical Summary

Problems solved by technology

[0010] However, at present, power supply manufacturers use commercialized power supplies and DC power supply module boards, and it is difficult to clearly identify the power supply or DC power supply specifications on the outside, resulting in errors in assembling the modular power supply system, such as DC The power module board is plugged into the wrong DC power port on the backplane module; moreover, the modular power supply system still needs to customize the backplane module, so that the production efficiency cannot be effectively improved; therefore, such a modular power supply The modular architecture of the system still needs further improvement
