Titre : Harmonic impact on distribution transformer no-load loss Type de document : texte imprimé Auteurs : Kefalas, Themistoklis D., Auteur ; Kladas, Antonios G., Auteur Article en page(s) : pp. 193 - 200 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Finite element methods Industrial power system harmonics Magnetic anisotropy Magnetic cores Magnetic hysteresis Magentic losses Nonlinear magnetics Power transformers Soft magnetic materials Transient analysis Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : The losses in European Union distribution transformers are estimated at about 33 TW ·h/year, whereas reactive power and harmonic losses add a further 5 TW ·h/year. The reduction of distribution transformer no-load loss is particularly important as the ratio of no-load to load losses is nearly three. In this paper, the no-load operation of wound-core transformers under sinusoidal and distorted supply-voltage conditions is investigated. For that purpose, a 2-D nonlinear transient finite-element analysis taking into account hysteresis has been developed. The hysteresis model is based on a modified Jiles-Atherton representation, and the proposed analysis is compared to experimental data.

Titre : Internal permanent magnet motor design for electric vehicle drive Type de document : texte imprimé Auteurs : Laskaris, Konstantinos I., Auteur ; Kladas, Antonios G., Auteur Article en page(s) : pp. 138 - 145 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Finite element (FE) methods Geometry optimization Losses Permanent magnet machines Power density Wheel motor Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Power compaction and high efficiency are two key advantages of permanent magnet motors. This paper proposes an enhanced internal permanent magnet motor that delivers high torque, power compaction, and exceptionally high efficiency in the same operation area. The advantage of the proposed scheme is the magnetic flux accumulation in the air gap, which allows much higher values of magnetic flux density, compared to a surface permanent magnet motor of the same size. The original contribution of this paper resides on the adopted motor configuration, enabling to efficiently utilize the energy stored in the permanent magnet and to provide total loss minimization at the most frequently used speed range.
