Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 3 (Mars 2010) . - pp. 831 - 839 Titre : An efficient wind–photovoltaic hybrid generation system using doubly excited permanent-magnet brushless machine Type de document : texte imprimé Auteurs : Chunhua, Liu, Auteur ; Chau, K. T., Auteur ; Xiaodong, Zhang, Auteur Article en page(s) : pp. 831 - 839 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Maximum-power-point  tracking  (MPTT)  Permanent-magnet  (PM)  brushless  machine  Photovoltaic  (PV)  Wind  power Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : With ever-increasing concerns on energy issues, the development of renewable energy sources is becoming more and more attractive. This paper first reviews both the wind power and photovoltaic (PV) power generation techniques and their maximum-power-point tracking (MPPT) methods. Then, a new stand-alone wind-PV hybrid generation system is proposed for application to remote and isolated areas. For the wind power generation branch, a new doubly excited permanent-magnet brushless machine is used to capture the maximum wind power by using online flux control. For the PV power generation branch, a single-ended primary inductance converter is adopted to harness the maximum solar power by tuning the duty cycle. The experimental results confirm that the proposed hybrid generation system can provide high efficiency with the use of MPPT.

A Permanent-magnet hybrid brushless integrated starter–generator for hybrid electric vehicles / Chunhua, Liu in IEEE transactions on industrial electronics, Vol. 57 N° 12 (Décembre 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 12 (Décembre 2010) . - pp. 4055 - 4064 Titre : A Permanent-magnet hybrid brushless integrated starter–generator for hybrid electric vehicles Type de document : texte imprimé Auteurs : Chunhua, Liu, Auteur ; Chau, K. T., Auteur ; Jiang, J. Z., Auteur Année de publication : 2011 Article en page(s) : pp. 4055 - 4064 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Hybrid  electric  vehicle  (HEV)  Hybrid  filed  excitation  Integrated  starter-generator  (ISG)  Permanent-magnet  (PM)  machine Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A new permanent-magnet (PM) hybrid brushless (PMHB) machine is proposed and implemented as the integrated starter-generator (ISG) for hybrid electric vehicles (HEVs). It has the advantages of higher torque density than other PMHB machines and much wider speed range than other PM brushless machines. The key is to tune its dc-field winding current in such a way that three major modes of ISG system operation for HEVs, namely, engine cranking, battery charging, and torque boosting, can be achieved effectively. The finite-element method is employed to simulate its steady-state and dynamic performances. Finally, a 2-kW prototype is constructed and tested to experimentally verify the simulation results and the validity of the proposed ISG system.
