Abstract
A novel tri-state pseudo-continuous conduction mode (PCCM) Flyback power factor correction (PFC) converter and its corresponding control strategy are proposed to improve load power. The proposed converter is built with double MOSFET formed half bridge and operated in PCCM, which provides an additional degree of control freedom for simplifying the PFC controller. The tri-state PCCM Flyback converter can improve the load power effectively compared with the conventional DCM Flyback PFC converter at constant switching frequency. Analyses and 200W prototypes of the tri-state PCCM Flyback PFC converter and conventional DCM Flyback PFC converter have been presented. The results show that the proposed tri-state PCCM Flyback PFC converter is suitable for heavier load power compared with conventional DCM Flyback PFC converter.
