A method for a single-phase or polyphase three-point converter which is connected to a DC voltage intermediate circuit, series-connected main switches/inverse diodes between each DC voltage connection and each load connection, with the common junction point forming the load connection, and with an active clamped switch with an inverse diode being connected between each common junction point of an inner main switch and an outer main switch and the centre tap of the DC voltage intermediate circuit, as a result of which two possible paths are formed for connecting a load connection to the centre tap. At least one active clamped switch is connected to the centre tap together with at least one inner main switch for connection of a load connection, so as to carry the current deliberately through the upper path and/or the lower path to the centre tap during a null state.

L'invention concerne un procédé de commande et de régulation pour un convertisseur de courant en montage Hartley monophasé ou polyphasé, comportant deux interrupteurs principaux (T1, T2, T3, T4) / diodes inverses (D1, D2, D3, D4) montés en série, entre chaque connexion de tension continue et chaque connexion de charge, le point de connexion commun des deux interrupteurs principaux intérieurs (T2, T3) formant la connexion de charge, cependant qu'entre chaque point de connexion commun d'un interrupteur principal intérieur (T2, T3) avec un interrupteur principal extérieur (T1, T4) et la prise médiane du circuit intermédiaire à tension continue, il est prévu un interrupteur de verrouillage actif (T5, T6) à diodes inverses, de manière à réaliser deux trajets possibles permettant la jonction d'une connexion de charge avec la prise médiane. L'invention est caractérisée en ce qu'indépendamment du sens du courant de charge, au moins l'un des deux interrupteurs actifs (T5, T6) est mis en circuit, conjointement avec au moins un interrupteur principal intérieur (T2, T3) pour la jonction d'une connexion de charge avec la prise médiane, de façon que le courant circule, de manière appropriée, pendant un état zéro, à travers le trajet supérieur, le trajet inférieur ou les deux trajets de la prise médiane.
