Title (DE) VORRICHTUNG ZUR SPANNUNGSWANDLUNG
(EN) VOLTAGE TRANSFORMER
(FR) DISPOSITIF DE TRANSFORMATION DE TENSION
Abstract:
(DE) Es wird eine Vorrichtung zur Spannungswandlung angegeben, die insbesonders in Kraftfahrzeugen eingesetzt werden soll. Zur Spannungswandlung werden mehrere kleine Spannungswandler als Teilwandler zueinander parallel geschaltet. Durch sequentielles Einschalten der einzelnen Teilwandler und Überlagerung des Ausgangsstromes wird ein gleichmäßiger Ausgangsstrom bei geringer Eingangsbelastung erzielt.
(EN) The invention pertains to a voltage transformer intended for use in vehicles. In order to carry out that voltage transformation, a plurality of small transformers operating as partial transformers are arranged parallel to each other. Owing to the sequentially connected partial transformers and the output current ripple, a steady output current flow can be obtained with a low input charge.
(FR) La présente invention porte sur un dispositif de transformation de tension conçu pour être placé notamment dans des véhicules. Pour opérer cette transformation de tension, plusieurs petits transformateurs à fonction de transformateurs partiels sont disposés en alignement parallèle. Grâce au branchement séquentiel des divers transformateurs partiels et à la superposition du courant de sortie, on obtient un courant de sortie régulier pour une faible charge à l'entrée.
