Abstract

The invention discloses a power supply stability analysis device and a power supply system. The power supply stability analysis device comprises a first voltage sampling circuit, a second voltage sampling circuit and a control circuit. A power supply voltage load curve can be generated according to the load end voltage detected by means of an original BMC voltage detection module in the system, and manual measurement is not needed; moreover, the voltage sampling circuit is additionally arranged to analyze the line loss voltage of the power supply voltage from the source end to the rear end load, so as to correct the voltage of the load end according to the line loss voltage, obtain a more accurate voltage of the load end, obtain a more accurate power supply voltage load curve, and facilitate the stability analysis of the power supply.

Description

technical field [0001] The invention relates to the field of power supplies of server systems, in particular to a power supply stability analysis device and a power supply system. Background technique [0002] In a server system, the stability of the system power supply directly affects the reliability and stability of the entire system. At present, an important technical indicator in power supply stability evaluation is the load curve of the power supply voltage, that is, the stability of the power supply can be analyzed through the load curve of the power supply voltage. The load curve of the power supply voltage means that the power supply is under rated input voltage and rated Within the output current range, the output voltage change curve when pulling (driving) different load currents. [0003] In the prior art, the way to obtain the load curve of the power supply voltage is: connect the power supply to an external load, and manually measure the output voltage of the ...
