Abstract

See full text

Disclosed herein are an AC-DC converter in which an inductor of boost PFC and a flyback transformer are integrated in one and a method of preventing a magnetic density from being saturated by shifting a phase. The integrated magnetic circuit according to an exemplary embodiment of the present invention includes: a power factor correction stage (PFC-stage) including a boost inductor; and a flyback transformer including a primary winding and a secondary winding, wherein the boost inductor and the primary winding of the flyback transformer and the secondary winding of the flyback transformer are wound around a single core.
