Improving Filter Performances for Conducted Electromagnetic Interferences Suppression
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2014, Vol 21, Issue 3
Abstract
Improving the performances of a filter for conductive electromagnetic interferences suppression involves two major directions of action: the first direction refers to the increase of attenuation at high frequency, while the second direction refers to the suppression of the parasitic effects in the constitutive devices. Thus, in this light, the paper presents the authors’ contribution to the two major directions of actions mentioned above; in the first part, techniques for HF loss increase are presented, while in the second part techniques for minimizing the structural parasitic capacitance are shown. In the third part of the paper these techniques are applied simultaneously to an EMI filter made in planar electromagnetic technology in order to study its performance.
