Multilevel topologies have now to serve new purposes, and interest is rising in new application fields. Recent multilevel technologies have the potential to significantly reduce the size of passive filters, thus increasing efficiency and power density. With the more stringent regulations concerning harmonic emissions and reliability concerns, more levels are needed to allow filterless operation while keeping a moderate switching frequency and simple structure. In this context, the new topological family of high-density advanced multilevel inverters, called cross-connected intermediate-level voltage source inverter, is introduced in this paper.

The common cross-connected stage for the 5L ANPC medium voltage multilevel inverter / Chaudhuri, Toufann 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. 2279 - 2286 Titre : The common cross-connected stage for the 5L ANPC medium voltage multilevel inverter Type de document : texte imprimé Auteurs : Chaudhuri, Toufann, Auteur ; Rufer, Alfred, Auteur ; Steimer, Peter K., Auteur Article en page(s) : pp. 2279 - 2286 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Cross  connected  Multilevel  Phase  capacitors  Voltage  source  inverter Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Rising interest in multilevel applications has triggered new research activities. This paper proposes a novel multilevel power electronics building block (PEBB) for the five-level active neutral point clamped (ANPC) multilevel voltage source inverter. The PEBB is composed of six switches in a crossed configuration and one capacitor. It is common to the three phases of a five-level ANPC topology, enabling a large number of levels to be generated. This PEBB is meant to be a reliable upgrade to the 5L topology, increasing output signal quality and reducing the size of the output filter in medium voltage applications. The number of levels generated by the common cross-connected stage (C3S) PEBB and the ANPC depends on the voltage ratios chosen between the phase capacitors of the ANPC and the PEBB capacitor(s). The tradeoff stands between the ability to balance the capacitors, the rated blocking voltage of the devices, and the number of levels produced. Under a given configuration, nine levels can be produced, with the possibility to balance the capacitors up to modulation indexes in the region of m = 0.92. The analysis of the general topology, the description of the nine-level case, and simulation results are first presented. Prototyping results are then shown, and they validate the introduced concept and topology.
