Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Asymmetrical cascade multilevel inverters offer a high number of voltage levels with a given switch count. For a given topology, the number of levels depends on the configuration of the dc voltage (ratios). This paper deals with the design and control of such converters with noninteger dc voltage ratio, which leads to unevenly distributed space vectors. It describes how to select the dc voltage ratio configurations that yield space vectors as evenly distributed as possible. It describes how to produce an effective PWM modulation that allows generating undistorted current even in the presence of (some) unevenly distributed space vectors.

Comparison of hybrid control techniques for buck and boost DC-DC converters / Mariéthoz, Sébastien in IEEE Transactions on control systems technology, Vol. 18 N° 5 (Septembre 2010) 

Public ISBD [article]  in IEEE Transactions on control systems technology > Vol. 18 N° 5 (Septembre 2010) . - pp. 1126-1145 Titre : Comparison of hybrid control techniques for buck and boost DC-DC converters Type de document : texte imprimé Auteurs : Mariéthoz, Sébastien, Auteur ; Stefan Almer, Auteur ; Mihai Bâja, Auteur Année de publication : 2011 Article en page(s) : pp. 1126-1145 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : DC-DC  Hybrid  control  Model  predictive  control  (MPC)  Robust  control  Sampled  data  control Index. décimale : 629.1 Résumé : Five recent techniques from hybrid and optimal control are evaluated on two power electronics benchmark problems. The benchmarks involve a number of practically interesting operating scenarios for fixed-frequency synchronous dc-dc converters. The specifications are defined such that good performance can only be obtained if the switched and nonlinear nature of the problem is accounted for during the design phase. A nonlinear action is featured in all methods either intrinsically or as external logic. The designs are evaluated and compared on the same experimental platform. Experiments show that the proposed methods display high performances, while respecting circuit constraints, thus protecting the semiconductor devices. Moreover, the complexity of the controllers is compatible with the high-frequency requirements of the considered application.
