Abstract

The invention discloses a server power supply forced current sharing method and system, equipment and a storage medium. The server power supply forced current sharing method comprises the steps of: reading output currents of a plurality of server power supplies, and calculating the total output current; in response to voltage drop of a current-sharing bus, calculating a current value needing to beoutput by each server power supply according to the total output current and a preset proportion, and taking the current value needing to be output as a target current value; sequentially adjusting the output voltage of each server power supply according to the change sequence of the current values from small to large, and keeping output voltages of other server power supplies unchanged every time the current server power supply is adjusted; and judging whether the output currents of the server power supplies reach the respective target current values or not, and stopping adjustment in response to the fact that the output currents of the server power supplies reach the respective target current values. According to the server power supply forced current sharing method and the system, theserver power supplies adjusted, so that a fault caused by bus voltage drop due to short circuit of the current-sharing bus or other anomalies is avoided, and the stability of the server power suppliesis improved.

Description

technical field [0001] The present invention relates to the field of server power supplies, more specifically, to a method, system, computer equipment and readable medium for forced current sharing of server power supplies. Background technique [0002] With the development of server applications, informatization has gradually covered all fields of society. People's daily work and life are more and more communicated through the network, and the amount of network data is also increasing. As the power supply center of the server, more and more power supplies are used. At present, multiple server power supplies are connected in parallel, that is, multiple power supplies are plugged into the server and powered on at the same time. Generally, multiple power supplies work with current sharing, that is, each power supply bears a similar load. Or some power supplies are working and some power supplies are in standby state. Through the forced current sharing function, the system sid...
