Public ISBD [article]  inCOST > N° 11 [01/07/2012] . - p. 39 Titre : Multilevel Neutral Point Double Clamping Converter for PM Synchronous motors drive Type de document : texte imprimé Auteurs : S. Stamnin, Auteur ; K. Belmekki, Auteur ; S. Belmehdi, Auteur ; D. Slamnia, Auteur Année de publication : 2012 Article en page(s) : p. 39 Langues : Anglais (eng) Mots-clés : NPC inverter  clamping bridge  rectifier multilevel  PWM strategy  regulation  enslavement Résumé : The aim of this paper is to give a solution to unbatance problem of the input DC voltages of nine-level NPC-VSI used in high voltage and great power applications [1]. For that, one two-level PWM current rectifier-nine-level NPC VSI-PMSM cascade is presented. In the first part, we develop a knowledge model of nine-level NPC VSI and offers a space vector modulation of this converter . In the first case the input DC voltages of the multilevel inverter are assumed constant and equals, After that, we propose to study a new high voltage cascade two-level PWM current rectifier-nine-level NPC VSI-PMSM. This study shows particularly the problem of the stability of the DC voltages of the inverterl. Then, we propose a solution to the problem by employee closed loop regulation using classic PI regulator mode, We add 2 Clamping bridge to stabilize the eight DC input voltages of nine-level NPC VSI.
