Critical parameters and constraints determining the cancellation frequency ranges are identified, and the effective frequency range for each cancellation method is derived based on these constraints. Due to these constraints, each method has specific advantages for certain applications. The cancellation techniques, which all make use of either mutual capacitance or mutual inductance, are applied to different applications based on their advantages, and the experiments are carried out to verify the analysis.

Parasitic effects of grounding paths on common-mode EMI filter's performance in power electronics systems / Shuo, Wang in IEEE transactions on industrial electronics, Vol. 57 N° 9 (Septembre 2010)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 57 N° 9 (Septembre 2010) . - pp. 3050 - 3059 Titre : Parasitic effects of grounding paths on common-mode EMI filter's performance in power electronics systems Type de document : texte imprimé Auteurs : Shuo, Wang, Auteur ; Maillet, Yoann Yorrick, Auteur ; Fei Wang, Auteur Année de publication : 2011 Article en page(s) : pp. 3050 - 3059 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Electromagnetic-interference (EMI) filter Grounding Inductive coupling Motor drive Mutual inductance Parasitic Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : High-frequency common-mode (CM) electromagnetic-interference (EMI) noise is difficult to suppress in electronics systems. EMI filters are used to suppress CM noise, but their performance is greatly affected by the parasitic effects of the grounding paths. In this paper, the parasitic effects of the grounding paths on an EMI filter's performance are investigated in a motor-drive system. The effects of the mutual inductance between two grounding paths are explored. Guidelines for the grounding of CM EMI filters are derived. Simulations and experiments are finally carried out to verify the theoretical analysis.
