Abstract
Disclosed is a toroidal line filter with coils wound through various winding processes such that an inductance characteristic for a certain frequency can be improved through changes in current flowing direction and/or area, whereby the toroidal line filter can compensate for a poor EMI characteristic at the certain frequency without adding extra components such as an inductor or a capacitor. The toroidal line filter comprises an annular core and coils wound around the annular core. The coils are wound in such a way that first winding is wound over a predetermined partial area of the annular core, which is not the entire area of the annular core, and then second winding is wound over the remaining area of the annular core.
