Power correction circuit anomaly detection method, system and circuit

Abstract

The invention discloses a power correction circuit anomaly detection method, system and circuit. The method comprises the steps: collecting feedback loop voltage values, control loop voltage values and working currents outputted by multiple groups of power correction circuits and output voltages and output currents of a main power circuit; utilizing the output voltage and the output current corresponding to each group to obtain a plurality of groups of output power; averaging the multiple groups of output power to obtain average output power; when the average output power is smaller than a preset output power threshold value; if so, gradually judging whether the power outputted by the main power circuit and the voltage and current of the power correction circuit are in a normal range; whether the power correction circuit is abnormal due to device parameter drifting or not can be detected in advance, if the power correction circuit is abnormal, abnormal information can be reported as soon as possible, maintenance personnel are reminded to prepare for maintenance, early prediction of faults is achieved, it is ensured that a power source corresponding to the abnormal power correctioncircuit can be replaced in time, and problem diffusion is prevented.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a method, system and circuit for abnormality detection of a power correction circuit. Background technique [0002] With the rapid development of the Internet economy, massive data is impacting the entire data center industry with an unprecedented growth trend. A large number of data centers are under construction and put into use, and the demand for servers is huge. The parameter drift of some components causes the power correction circuit of the power supply to work abnormally, and in some applications, causes the abnormality of the whole server or the tripping of the upper-level power supply unit of the power supply. [0003] In the existing technology, the power supply alarm is usually reported after the power supply fails or the corresponding protection mechanism is triggered, or the positive and negative compensation is adjusted to confirm whether the inductance i...

The parameter drift of some components causes the power correction circuit of the power supply to work abnormally, and in some applications, it causes the abnormality of the whole server or the tripping of the upper-level power supply unit of the power supply

[0003] In the existing technology, the power supply alarm is usually reported after the power supply fails or the corresponding protection mechanism is triggered, or the positive and negative compensation is adjusted to confirm whether the inductance is offset. The above two methods cannot let the user know in advance that the power correction circuit has occurred. The work is abnormal. Once the power correction circuit is known to be working abnormally through the above method, the power correction circuit needs to be maintained immediately, resulting in an abnormality of the server or a trip of the upper-level power supply unit of the power supply, which may easily cause data loss and cause serious problems in production and life. economic loss
