摘要： A power supply module having a PFC stage has a hold-up capacitor (34) for continuing output power for a time after an ac power supply (2) stops. The hold-up capacitor is charged by a winding (40) driven magnetically from a first winding (24); the first winding (24) may be the winding used in a boost converter stage, such as commonly used in a PFC stage, or alternatively the winding in an alternative stage such as a flyback converter.
