  • Transformer core
    Patent number: 6985063
    Abstract: A transformer core that can realize a winding having a fractional number of turns. At least one of the two side posts of the transformer core has a trench or a through hole. The winding on the side post passes through the trench or the through hole. For a POT-type transformer core, the trench or the through hole is formed on the bobbin, and winding passes through the trench or the through hole on the bobbin.
    Type: Grant

  • Integrated filter with common-mode and differential-mode functions
    Patent number: 6642672
    Abstract: 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.
