description The utility model discloses a PFC circuit for a high input voltage, wherein the PFC (Power Factor Correction) circuit comprises a PFC booster module, a PFC control module and a DC high-voltage output module; the external power supply is boosted by the PFC booster module and then is output by the DC (direct current) high-voltage output module; and the PFC control module controls the PFC booster module to work. The PFC circuit has a simple structure and only one level of booster driving circuit needs to be additionally increased. The PFC circuit has wide application scope and can be applied to all APFC (Active Power Factor Correction). During the application, the PFC circuit for high input voltage is applicable to single-phase electricity or three-phase electricity; and the input voltage ranges from 200Vac to 480Vac.
