Filter Common Mode Inductors For Suppressing Emi Noise Of Electronic Equipment
The line filter prevents excessive noise from being generated between the electronic equipment and the AC line; in general, the focus is on the protection of the AC line. When using a common mode filter between the AC line (through a full impedance matching circuit) and the (noise) power converter. The common mode noise (noise is generated on the two grounded lines at the same time) moves in the direction of the filter from the load end, so that the noise shared by the two lines is greatly attenuated. Finally, the output of the filter added to the AC line (through a full impedance matching circuit) is so small that it can be ignored.
