Novel half-bridge inductive DC–DC isolated converters for fuel cell applications / Lembeye, Y. in IEEE transactions on energy conversion, Vol. 24 N°1 (Mars 2009)  

Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 24 N°1 (Mars 2009) . - pp. 203 - 210 Titre : Novel half-bridge inductive DC–DC isolated converters for fuel cell applications Type de document : texte imprimé Auteurs : Lembeye, Y., Auteur ; Bang, V. D., Auteur ; Lefevre, G., Auteur Année de publication : 2009 Article en page(s) : pp. 203 - 210 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : DC-DC power convertors  fuel cells  electronics  zero current switching  voltage switching Résumé : This paper proposes a new class of converters based on the inductive input converters for the design of a power electronic interface for fuel cell (FC) applications. After studying the half-bridge structure, two soft-switching dc-dc converters are analyzed: one operating in zero-voltage-switching (ZVS) mode and the other in zero-current-switching (ZCS) mode. The ZVS converter can overcome the drawbacks of the original structure but is more complicated. The ZCS converter cannot operate at duty cycles below 0.5, but is simpler and more suitable for FC applications. Flexible choice of components, low losses, high efficiency, and modular converter possibility are all interesting characteristics of these converters. Their operation principle and characteristics are presented in this paper. Experimental results on 2 kW converters of each structure validate the theoretical analysis.
