Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper gives an overview of medium-voltage (MV) multilevel converters with a focus on achieving minimum harmonic distortion and high efficiency at low switching frequency operation. Increasing the power rating by minimizing switching frequency while still maintaining reasonable power quality is an important requirement and a persistent challenge for the industry. Existing solutions are discussed and analyzed based on their topologies, limitations, and control techniques. As a preferred option for future research and application, an inverter configuration based on three-level building blocks to generate five-level voltage waveforms is suggested. This paper shows that such an inverter may be operated at a very low switching frequency to achieve minimum on-state and dynamic device losses for highly efficient MV drive applications while maintaining low harmonic distortion.

Synchronous optimal pulsewidth modulation for low-switching-frequency control of medium-voltage multilevel inverters / Rathore, Akshay K. 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. 2374 - 2381 Titre : Synchronous optimal pulsewidth modulation for low-switching-frequency control of medium-voltage multilevel inverters Type de document : texte imprimé Auteurs : Rathore, Akshay K., Auteur ; Holtz, Joachim, Auteur ; Boller, Till, Auteur Article en page(s) : pp. 2374 - 2381 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Medium-voltage  drives  Multilevel  inverters  Optimization  Synchronous  optimal  pulsewidth  modulation  (PWM) Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents the mechanism and details of synchronous optimal pulsewidth modulation (PWM) generation for control of medium-voltage induction motor drives using multilevel inverters at low switching frequency. Multilevel inverters allow operation at multiple of dc-link voltage and reduce the total harmonic distortion (THD). Synchronous optimal PWM control permits setting the maximum switching frequency to a low value without compromising THD. Low switching frequency reduces the switching losses of the power semiconductor devices. An optimal control procedure is explained in detail. The performances of three- and five-level inverter topologies are compared. The experimental results of a five-level inverter drive using optimal PWM control are presented.
