This paper presents and validates an original contactless near-field scan-based method to quantify the performance of EMC filter mounted on power converter boards. The proposed method provides indicators about EMC filter attenuation, decoupling capacitor efficiency and differential-mode to common-mode conversion and may help designer to clarify and debug conducted emission issues of power converter boards.
