Download or read book La commutation douce dans la conversion statique de l nergie lectrique written by Yvon Chéron and published by Tec & Doc. This book was released on 1989 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE TRAITE D'UNE NOUVELLE CONCEPTION DE LA CONVERSION STATIQUE DE L'ENERGIE ELECTRIQUE, FONDEE SUR UNE RECHERCHE SYSTEMATIQUE DE LA COMMUTATION QUI INDUIT LE MINIMUM DE CONTRAINTES SUR LES INTERRUPTEURS: LA COMMUTATION DOUCE. L'AUTEUR PRECISE D'ABORD UN CERTAIN NOMBRE DE NOTIONS FONDAMENTALES DE L'ELECTRONIQUE DE PUISSANCE ET EN INTRODUISANT LA DUALITE, TANT AU NIVEAU DES STRUCTURES ET DES INTERRUPTEURS QUE DES MECANISMES DE COMMUTATION, IL DONNE UNE DIMENSION SUPPLEMENTAIRE A LA DISCUSSION. L'ANALYSE DES PERFORMANCES D'UNE CLASSE DE CONVERTISSEURS, LES ONDULEURS A RESONANCE, MONTRE QU'ELLES TROUVENT LEURS ORIGINES DANS LES MECANISMES PARTICULIERS DE COMMUTATION DES INTERRUPTEURS QUI POSSEDENT CHACUN UNE COMMUTATION COMMANDEE ET UNE COMMUTATION SPONTANEE. LA COMMUTATION DOUCE EST AINSI MISE EN EVIDENCE AVEC SES AVANTAGES, NOTAMMENT LA REDUCTION DES PERTES ET DE LA POLLUTION DE L'ENVIRONNEMENT DU CONVERTISSEUR. APRES AVOIR DETERMINE LES REGLES D'OBTENTION DE LA COMMUTATION DOUCE, L'AUTEUR PROPOSE UNE APPROCHE NOUVELLE DE LA CONVERSION STATIQUE BASEE SUR L'EXPLOITATION SYSTEMATIQUE DE CE TYPE DE COMMUTATION. LES CONVERTISSEURS A RESONANCE FORMENT LA PRINCIPALE FAMILLE DE CES NOUVEAUX CONVERTISSEURS CONTINU-CONTINU, TOUT D'ABORD NON RESERSIBLES, PUIS REVERSIBLES. IL MONTRE ALORS COMMENT ON PEUT CONCEVOIR LA CONVERSION CONTINU-ALTERNATIF ET DEBOUCHE ENFIN SUR UNE GENERALISATION DU PROCEDE A TOUTES LES FORMES DE CONVERSION. LES MONTAGES PROPOSES SONT ORIGINAUX ET ONT FAIT L'OBJET DE DEPOTS DE BREVETS. APRES AVOIR DONNE LES REGLES DE DIMENSIONNEMENT DE CES NOUVEAUX CONVERTISSEURS, LE MEMOIRE DE THESE SE TERMINE PAR UNE DESCRIPTION DES REALISATIONS INDUSTRIELLES QUI EXPLOITENT DEJA LES RESULTATS DE CETTE ETUDE. DE NOMBREUSES ANNEXES EXPLICITENT CERTAINES METHODES D'ETUDE OU MODES SPECIFIQUES DE COMMANDE

Download or read book Electronique de puissance written by Philippe Barrade and published by EPFL Press. This book was released on 2006-01-01 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'électronique de puissance est aujourd'hui une discipline en plein essor, notamment grâce aux nouveaux champs d'applications liés au développement durable et aux énergies renouvelables. Ses bases reposent sur plusieurs décennies d'activités de recherche et développement, que l'auteur expose dans ces pages. Cet ouvrage offre en effet un large exposé sur les structures élémentaires de la conversion statique. Son objectif consiste à proposer une démarche d'analyse et de conception reposant sur une méthode d'étude systématique, et non pas à présenter une simple liste exhaustive des convertisseurs statiques. Fort de cette méthodologie, les montages de base de l'électronique de puissance sont exposés dans le détail, et complétés d'une introduction à la conversion multiniveau. Accompagné d'un CD-Rom d'exercices animés et résolus, cet ouvrage est en premier lieu destiné aux étudiants électriciens ainsi qu'à leurs professeurs. Il constitue en outre une bonne introduction à l'électronique de puissance pour toutingénieur souhaitant s'initier à cette matière.

Download or read book Power Electronic Converters written by Robert Bausiere and published by Springer. This book was released on 2014-03-12 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the third in a series of four devoted to POWER ELECTRONIC CONVERTERS: The first of these concerns AC to DC conversion. The second concerns AC to AC conversion. This volume examines DC to DC conversion. The fourth is devoted to DC to AC conversion. Converters which carry out the DC-DC conversion operate by chopping the input voltage or current: they are called choppers or switch-mode power converters. Their operating frequency is not imposed by either the input or the output, both of which are at zero frequency. A frequency which is much greater than that of the industrial network can be chosen, provided that suitable configurations and semiconductor devices are used. This is the first difference compared to the rectifiers and AC-AC converters, analyzed in the previous volumes and which often operate at the industrial network frequency. The second difference concerns the commutation mode. Choppers operate in forced commutation. The beginning of an operating phase does not auto matically turn off the semiconductor devices which were conducting during the previous phase and which have to be brought to the blocking state. This turn-off must be carried out autonomously. These two differences - the higher frequency of commutations and, espe cially, the different mode of commutation -justify the first two chapters in this work: - Chapter 1 examines general notions concerning converters, supplies and loads, and more especially, how they can be characterized with regard to commutations.
