摘要： An integrated filter with both common-mode and differential-mode functions is disclosed. The integrated filter comprises a magnetic core, two windings and a frame for installing the windings. The magnetic core further comprises a rectangular core and an I-shaped core. The frame is fixed to a column of the rectangular core. These two windings are wound on the frame. The I-core is placed across an interior opening of the rectangular core and between these two windings. One integrated filter with a magnetic core composed of a &thgr;-shaped core and an I-shaped core is also disclosed. In addition, the magnetic core may comprise a &thgr;-shaped core and an E-shaped core. The E-core is placed across an interior opening of the &thgr;-shaped core or upright on the &thgr;-shaped core and between these two windings. One integrated filter with a magnetic core composed of a rectangular core and an E-shaped core is also disclosed.
