Tubes à rayons X Résumé : Multilevel cascaded H-bridge (CHB) converters have been presented as a good solution for high-power applications. In this way, several control and modulation techniques have been proposed for this power converter topology. In this paper, the steady-state power balance in the cells of a single-phase two-cell CHB is studied. The capability to be supplied with active power from the grid or to deliver active power to the grid in each cell is analyzed according to the dc-link voltages and the desired ac output voltage value. The limits of the maximum and minimum input active powers for a stable operation of the CHB are addressed. Simulation results are shown to validate the presented analysis.

Conventional space-vector modulation techniques versus the single-phase modulator for multilevel converters / Leon, José I. in IEEE transactions on industrial electronics, Vol. 57 N° 7 (Juillet 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 7 (Juillet 2010) . - pp. 2473 - 2482 Titre : Conventional space-vector modulation techniques versus the single-phase modulator for multilevel converters Type de document : texte imprimé Auteurs : Leon, José I., Auteur ; Vazquez, Sergio, Auteur ; Sanchez, Juan A., Auteur Article en page(s) : pp. 2473 - 2482 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Modulation  Multilevel  system Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Space-vector modulation (SVM) is a well-suited technique to be applied to multilevel converters and is an important research focus in the last 25 years. Recently, a single-phase multilevel modulator has been introduced, showing its conceptual simplicity and its very low computational cost. In this paper, some of the most conventional multilevel SVM techniques have been chosen to compare their results with those obtained with single-phase multilevel modulators. The obtained results demonstrate that the single-phase multilevel modulators applied to each phase are equivalent with the chosen well-known multilevel SVM techniques. In this way, single-phase multilevel modulators can be applied to a converter with any number of levels and phases, avoiding the use of conceptually and mathematically complex SVM strategies. Analytical calculations and experimental results are shown, validating the proposed concepts.

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.
