A different multilevel current-source inverter / Vazquez, Nimrod 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. 2623 - 2632 Titre : A different multilevel current-source inverter Type de document : texte imprimé Auteurs : Vazquez, Nimrod, Auteur ; Lopez, Hector, Auteur ; Hernandez, Claudio, Auteur Année de publication : 2011 Article en page(s) : pp. 2623 - 2632 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Current  source  Dc/ac  converter  Low  harmonic  distortion  Multilevel  converter Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : DC/AC converters are widely used in several applications; traditionally, they can be classified in two types: the voltage-source inverters (VSIs) and the current-source inverters (CSIs). Their use depends on their application; however, some of them are common for both types of converters. Another possibility for the dc/ac conversion is the multilevel configuration, and the most analyzed is the VSI. In this paper, a different multilevel CSI is proposed: the paralleled configuration. To control the converter, a different sinusoidal pulse with modulation is employed; it consists of modifying the reference signal instead of using multiple carriers. Additionally, a balancing method for the inductor currents is given. The operation, analysis, and implementation are presented; moreover, simulation and experimental results are shown.

Dynamical sliding-mode control of the boost inverter / Cortes, Domingo in IEEE transactions on industrial electronics, Vol. 56 N° 9 (Septembre 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 9 (Septembre 2009) . - pp. 3467-3476 Titre : Dynamical sliding-mode control of the boost inverter Type de document : texte imprimé Auteurs : Cortes, Domingo, Auteur ; Vazquez, Nimrod, Auteur ; Alvarez-Gallegos, Jaime, Auteur Article en page(s) : pp. 3467-3476 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Sliding-mode  control  Boost  inverter Index. décimale : 621 Ingénierie mécanique en général. Technologie nucléaire. Ingénierie électrique. Machinerie Résumé : The boost inverter is a device that is able to generate a sinusoidal voltage with an amplitude larger than the input voltage. Based on the idea of indirectly controlling the output voltage through the inductor current, a dynamical sliding-mode controller for the boost inverter is proposed in this paper. Unlike the usual approach of generating a sinusoidal voltage in both capacitors of the boost inverter, the strategy proposed in this paper focuses on generating a sinusoidal voltage on the load despite the voltage form of both capacitors. A consequence of doing so is that only the desired output voltage is required as reference to implement the controller. Furthermore, it has a fast response, is robust under load and input voltage variations, and yet, is remarkably simple to implement. Although it is strongly nonlinear, it can be implemented using standard electronics circuitry and only needs voltage measurements.

Electric dynamic modeling of HID lamps for electronic ballast design / Sanchez, René Osorio in IEEE transactions on industrial electronics, Vol. 57 N° 5 (Mai 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 5 (Mai 2010) . - pp. 1655 - 1662 Titre : Electric dynamic modeling of HID lamps for electronic ballast design Type de document : texte imprimé Auteurs : Sanchez, René Osorio, Auteur ; Vazquez, Nimrod, Auteur ; Hernandez, Claudia, Auteur Année de publication : 2011 Article en page(s) : pp. 1655 - 1662 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Acoustic  resonances  Design  Electronics  ballast  High-intensity  discharge  (HID)  lamp  Modeling  Square  waveforms Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper describes a nonlinear model of high-intensity discharge (HID) lamps based on electrical variables. The proposal, oriented to the engineering area, has a special application for the design of electronic ballast. Parameters are obtained from straightforward measurement of electrical variables as power, current, and voltage in the lamp. The lamp resistance is obtained as a function of electrical power; which is estimated from the Saha equation. This model, which can be simulated using software such as ??Simulink?? or ??Pspice,?? takes into account some important dynamic behaviors of HID lamps, which are normally omitted in some other models suggested in literature nowadays. Experimental and simulation results are shown.
