Optimum design of the current-source flyback inverter for decentralized grid-connected photovoltaic systems / Kyritsis, A.Ch. in IEEE transactions on energy conversion, Vol. 23 N°1 (Mars 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 N°1 (Mars 2008) . - pp. 281 - 293 Titre : Optimum design of the current-source flyback inverter for decentralized grid-connected photovoltaic systems Type de document : texte imprimé Auteurs : Kyritsis, A.Ch., Auteur ; Tatakis, E.C., Auteur ; Papanikolaou, N.P., Auteur Année de publication : 2008 Article en page(s) : pp. 281 - 293 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : SPICE;  invertors;  photovoltaic  power  systems;  power  conversion Résumé : Two alternative modes of operation for the current-source flyback inverter are investigated in this paper. The discontinuous conduction mode (DCM), where a constant switching frequency (CSF) control method is applied, and the boundary between continuous and DCM (BCM) that is introduced for photovoltaic (PV) applications in this paper (where a variable switching frequency control method is applied). These two control methods are analytically studied and compared in order to establish their advantages as well as their suitability for the development of an inverter for decentralized grid-connected PV applications. An optimum design methodology is developed, aiming for an inverter with the smallest possible volume for the maximum power transfer to the public grid and wide PV energy exploitation. The main advantages of the current-source flyback inverter are very high-power density and high efficiency due to its simple structure, as well as high-power factor regulation. The design and control methodology are validated by personal computer simulation program with integrated circuit emphasis (PSPICE) simulation and experimental results, accomplished on a laboratory prototype.
