Abstract
Un appareil convertisseur de tension comprend un transformateur à fer saturable 10 comportant des enroulements primaire, secondaire et tertiaire, un premier et un second dispositif de commutation 18, 20 disposés pour connecter une source de tension d'entrée continue + V en circuit avec l'enroulement primaire 12 de telle sorte que les premier et second dispositifs de commutation, lorsqu'ils sont conducteurs, tendent respectivement à provoquer la saturation du transformateur dans des directions opposées, et un dispositif de sortie 29 couplé à l'enroulement secondaire 14. Un dispositif de commande 24 rend alternativement conducteurs le premier et le second dispositif de commutation, des périodes de non-conductivité se chevauchant étant intercalées entre les périodes de conductivité, et un dispositif de polarisation 26, 27 fait que l'enroulement tertiaire 16 assure la saturation du transformateur pendant chacune des périodes de non-conductivité avec chevauchement De cette façon, sont éliminés les problèmes résultant du déséquilibre entre les webers appliqués à l'enroulement primaire dans des directions opposées. L'invention trouve une application dans les convertisseurs continu/continu.
