Implementation of a transformerless common-mode active filter for offline converter systems / Heldwein, Marcelo Lobo in IEEE transactions on industrial electronics, Vol. 57 N° 5 (Mai 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 5 (Mai 2010) . - pp. 1772 - 1786 Titre : Implementation of a transformerless common-mode active filter for offline converter systems Type de document : texte imprimé Auteurs : Heldwein, Marcelo Lobo, Auteur ; Ertl, Hans, Auteur ; Biela, Jurgen, Auteur Année de publication : 2011 Article en page(s) : pp. 1772 - 1786 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Active  filter  Conducted  emissions  Three-phase  filters  Three-phase  PWM  converters Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a study and practical implementation of an active filter employing a high-frequency (HF) power amplifier and passive-filter components to be connected to the ac power lines in order to mitigate common-mode conducted emissions of three-phase pulsewidth modulation converter systems. The filter topology is chosen from different possibilities listed in a literature survey and studied regarding practical implementation issues, where requirements for an HF power amplifier to be applied in active filtering are derived. Special attention is put on the stability analysis where the challenges for the feedback are discussed, and a simple feedback structure is proposed. Other feedback concepts are analyzed, and limitations posed by stability requirements are presented. A prototype is designed and built, from which mathematical and experimental results are obtained demonstrating the potential and limitations of such a system.

Novel three-phase CM/DM conducted emission separator / Heldwein, Marcelo Lobo in IEEE transactions on industrial electronics, Vol. 56 N° 9 (Septembre 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 9 (Septembre 2009) . - pp. 3693-3703 Titre : Novel three-phase CM/DM conducted emission separator Type de document : texte imprimé Auteurs : Heldwein, Marcelo Lobo, Auteur ; Biela, Jurgen, Auteur ; Ertl, Hans, Auteur Article en page(s) : pp. 3693-3703 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Novel  three-phase  common-mode  Emission  separator Index. décimale : 621 Ingénierie mécanique en général. Technologie nucléaire. Ingénierie électrique. Machinerie Résumé : This paper presents two novel three-phase common-mode (CM)/differential-mode (DM) noise separation networks, which are passive and active networks, to be used in electromagnetic compatibility conducted emission (CE) measurements of three-phase equipment. The passive network is analyzed theoretically, and a prototype is constructed and tested. Its evaluation is presented through frequency response measurements and CE tests performed on a three-phase motor drive and verifies that the network is capable of separating the CM and DM information in a CE measurement condition.
