| Abstract |
This paper considers the effect of copper shields placed between differential-mode CLC filtercomponents and the effect of the component placement on conducted electromagnetic interference of aswitch-mode power supply. The study is based on comparative measurements of a power supplyconducted electromagnetic interference for different configurations of the differential-mode filter. It isshown that using printed circuit board with two metal layers and shields can improve electromagneticinterference attenuation introduced by the filter. |
