| Abstract: | A power converter control method, charge control,is studied. The relationship between the subharmonic oscillation and line/load condition of charge control is defined. A complete Small-signal analysis is performed. The small-signal model is confirmed. Using charge control, a Flyback converter can operate in continuous conduction-mode (CCM) with unity power factor. Due to its simplicity and low cost, Flyback PFC is suitable for low power applications. The results show good prospects of application. |
