Abstract

Convertisseur en phase bloquée comprenant un transformateur avec un primaire, un secondaire et un enroulement de réaction; un transistor de commutation dont le circuit émetteur-collecteur contient le primaire et dont la base est commandée par l'enroulement de réaction; un redresseur relié à l'enroulement secondaire et une résistance de commande de la base du transistor. Un élément de retard R28, R29, R30, R32, R33, C15, T7 est relié à l'un des enroulements du transformateur Trl de façon à pouvoir être commandé par ce dernier et bloque le transistor de commutation T8 après un temps prédéterminé.Blocked-phase converter comprising a transformer with a primary, a secondary and a feedback winding; a switching transistor the emitter-collector circuit of which contains the primary and the base of which is controlled by the feedback winding; a rectifier connected to the secondary winding and a control resistor of the base of the transistor. A delay element R28, R29, R30, R32, R33, C15, T7 is connected to one of the windings of the transformer Tr1 so as to be able to be controlled by the latter and turns off the switching transistor T8 after a predetermined time.
