Model predictive control of multilevel cascaded H-bridge inverters / Corteés, Patricio in IEEE transactions on industrial electronics, Vol. 57 N° 8 (Août 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 8 (Août 2010) . - pp. 2691 - 2699 Titre : Model predictive control of multilevel cascaded H-bridge inverters Type de document : texte imprimé Auteurs : Corteés, Patricio, Auteur ; Wilson, Alan, Auteur ; Kouro, Samir, Auteur Année de publication : 2011 Article en page(s) : pp. 2691 - 2699 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Cascaded  H-bridge  (CHB)  Current  control  Inverters  Model  predictive  control  (MPC)  Multilevel  inverters  Predictive  control Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a model predictive current control algorithm that is suitable for multilevel converters and its application to a three-phase cascaded H-bridge inverter. This control method uses a discrete-time model of the system to predict the future value of the current for all voltage vectors, and selects the vector which minimizes a cost function. Due to the large number of voltage vectors available in a multilevel inverter, a large number of calculations are needed, making difficult the implementation of this control in a standard control platform. A modified control strategy that considerably reduces the amount of calculations without affecting the system's performance is proposed. Experimental results for five- and nine-level inverters validate the proposed control algorithm.

Recent advances and industrial applications of multilevel converters / Kouro, Samir in IEEE transactions on industrial electronics, Vol. 57 N° 8 (Août 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 8 (Août 2010) . - pp. 2553 - 2580 Titre : Recent advances and industrial applications of multilevel converters Type de document : texte imprimé Auteurs : Kouro, Samir, Auteur ; Malinowski, Mariusz, Auteur ; Gopakumar, K., Auteur Année de publication : 2011 Article en page(s) : pp. 2553 - 2580 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Active  filters  (AFs)  Control  Flexible  AC  transmission  systems  (FACTS)  High-power  applications  High-voltage  direct-current  (HVDC)  transmission  Marine  propulsion  Modulation  Multilevel  converters  Photovoltaic  systems  Train  traction  Wind  energy  conversion Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Multilevel converters have been under research and development for more than three decades and have found successful industrial application. However, this is still a technology under development, and many new contributions and new commercial topologies have been reported in the last few years. The aim of this paper is to group and review these recent contributions, in order to establish the current state of the art and trends of the technology, to provide readers with a comprehensive and insightful review of where multilevel converter technology stands and is heading. This paper first presents a brief overview of well-established multilevel converters strongly oriented to their current state in industrial applications to then center the discussion on the new converters that have made their way into the industry. In addition, new promising topologies are discussed. Recent advances made in modulation and control of multilevel converters are also addressed. A great part of this paper is devoted to show nontraditional applications powered by multilevel converters and how multilevel converters are becoming an enabling technology in many industrial sectors. Finally, some future trends and challenges in the further development of this technology are discussed to motivate future contributions that address open problems and explore new possibilities.

Unidimensional modulation technique for cascaded multilevel converters / Leon, José I. in IEEE transactions on industrial electronics, Vol. 56 N° 8 (Août 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 8 (Août 2009) . - pp. 2981 - 2986 Titre : Unidimensional modulation technique for cascaded multilevel converters Type de document : texte imprimé Auteurs : Leon, José I., Auteur ; Vazquez, Sergio, Auteur ; Kouro, Samir, Auteur Article en page(s) : pp. 2981 - 2986 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Modulation  Multilevel  systems  Voltage  control Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a simple and low-computational-cost modulation technique for multilevel cascaded H-bridge converters. The technique is based on geometrical considerations considering a unidimensional control region to determine the switching sequence and the corresponding switching times. In addition, a simple strategy to control the dc-voltage ratio between the H-bridges of the multilevel cascaded converter is presented. Examples for the two-cell topology are shown, but the proposed technique can be applied to develop modulation methods for a higher number of H-bridges. Experimental results are presented to validate the proposed technique.
