ELECTROMAGNETIC INTERFERENCE FILTER AND METHOD OF MANUFACTURING THE SAME

摘要

There are provided an electromagnetic interference filter and a method of manufacturing the same. The electromagnetic interference filter includes a base core including a first base core and a second base core facing the first base core, a leg core including first and second leg cores disposed between the first base core and the second base core, the first and second leg cores facing each other, a winding coil part including first and second winding coils wound around the first and second leg cores, respectively, and connected to a power supply, the first and second winding coils respectively providing magnetizing inductance and leakage inductance, and a central core disposed between the first and second cores to provide an inductance leakage path between the first and second base cores.
