Abstract: An online upgrading method for a power supply, capable of enabling the power supply to simultaneously perform work output in the process of upgrading the power supply without using two sets of power supplies, and including: S1, determining whether the power supply needs to be corrected, and if the power supply needs to be corrected, sending an upgrading request to a master control chip; S2, the master control chip turning off any transformer in the power supply and sending a starting instruction to a secondary control chip, and the secondary control chip controlling the power supply to enter an upgrading mode according to the starting instruction; S3, when the power supply enters the upgrading mode, the power supply transmitting upgrading data to the secondary control chip by means of a transmission protocol.

Abstract: Disclosed are a Power Factor Correction (PFC) control method, apparatus, and device, and a computer-readable storage medium. The method includes: acquiring an input voltage value, input current value, and output voltage value from a PFC circuit (S101); acquiring a current reference value for current loop control by using a Prony's method according to the input voltage value, the output voltage value, and a preset voltage reference value (S102); and performing current loop control according to the current reference value and the input current value, and outputting a corresponding Pulse Width Modulation (PWM) signal, so as to control a switch tube in the PFC circuit to be correspondingly switched on or switched off (S103).
