Zusammenfassung:	Disclosed in embodiments of the present invention are a control method, apparatus, device, and medium for a power factor correction (PFC) circuit, used for solving the problems of high implementation costs and relatively severe THD that exist in existing PFC circuit control methods. The control method for a power factor correction (PFC) circuit, comprising: acquiring circuit parameter information of the PFC circuit; when determining that the circuit parameter information meets a preset switching condition, switching a control mode of the PFC circuit to be a continuous conduction mode (CCM). Des modes de réalisation de la présente invention concernent un procédé, un appareil, un dispositif et un support de commande pour circuit de correction de facteur de puissance (PFC), utilisés pour résoudre les problèmes de coûts élevés de mise en œuvre et de distorsion harmonique totale (THD) relativement importante qui existent dans des procédés de commande de circuit PFC existants. Le procédé de commande pour circuit de
