Analysis of flux-reversal machine based on fictitious electrical gear / More, D. S. in IEEE transactions on energy conversion, Vol. 25, N° 4 (Décembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 4 (Décembre 2010) . - pp. 940 - 947 Titre : Analysis of flux-reversal machine based on fictitious electrical gear Type de document : texte imprimé Auteurs : More, D. S., Auteur ; Fernandes, B. G., Auteur Année de publication : 2011 Article en page(s) : pp. 940 - 947 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Fourier  analysis;  air  gaps;  magnetic  flux;  permanent  magnet  machines;  poles  and  zeros;  stators;  synchronous  machines Résumé : This paper proposes a concept of fictitious “Electrical Gear” to analyze the flux pattern in the three-phase flux-reversal machine (FRM). The rotating-flux pattern of FRM has either two or four poles depending on the number of stator poles. FRM can be analyzed on similar lines as permanent magnet synchronous machine with the concept of this gear. The flux-density distribution in FRM is analyzed with Fourier analysis. The magnitude of various space harmonics and their contribution to the winding-flux linkages are determined. The procedure for finding the rms value of air-gap flux density from machine dimensions is described. In order to verify the aforementioned analysis, a 6/14 pole FRM with distributed and concentrated windings is designed and fabricated. The experimental results are compared with those obtained from finite-element method simulation studies and analytical results.

Unique power electronics and drives experimental bench (PEDEB) to facilitate learning and research / Sandeep Anand in IEEE transactions on education, Vol. 55 N° 4 (Novembre 2012) 

Public ISBD [article]  in IEEE transactions on education > Vol. 55 N° 4 (Novembre 2012) . - pp. 573 - 579 Titre : Unique power electronics and drives experimental bench (PEDEB) to facilitate learning and research Type de document : texte imprimé Auteurs : Sandeep Anand, Auteur ; Rajesh Singh, Auteur ; Fernandes, B. G., Auteur Année de publication : 2013 Article en page(s) : pp. 573 - 579 Note générale : Education Langues : Anglais (eng) Mots-clés : Do-it-yourself  Electric  drives  Laboratory  course  Power  conversion  Power  electronics  Reconfigurable  Teaching Résumé : Experimentation is important for learning and research in the field of power electronics and drives. However, a great deal of equipment is required to study the various topologies, controllers, and functionalities. Thus, the cost of establishing good laboratories and research centers is high. To address this problem, the authors have developed a “Power Electronics and Drives Experimental Bench” (PEDEB), whose details are given in this paper. This unique kit includes reconfigurable hardware modules, which can be interconnected to achieve more than 14 different circuit topologies. Moreover, the software (controller) is accessible to users, thereby facilitating quick verification and testing of new ideas. A 2-kVA prototype of the PEDEB was developed and tested for various possible modes of operation. The kit is being used for a first-semester post-graduate laboratory course on “Power Electronics and Drives.” This paper includes observations and learning from experiments on dc-dc buck converter, an induction motor drive, and a grid feeding inverter conducted using the PEDEB.
