Abstract
(DE)
Die Erfindung beschreibt ein Batterieladegerät (1) mit aktiver Gleichrichtung, mit zumindest einer Steuervorrichtung (1a), einem Gleichrichter (2), einer Brückenschaltung (5), einem Transformator (6) und einem Ausgangsgleichrichter bzw. einem Synchrongleichrichter (7) mit einem Ausgangsfilter. Sekundärseitig ist für jede Sekundärwicklung (13, 14) ein Stromsensor (10, 11) oder bei einer Sekundärwicklung zumindest ein oder zwei Stromsensoren (10, 11) vorgesehen, der mit einer Auswerteeinheit (12) zur Übertragung eines dem Stromwert korrespondierenden Signals (15), insbesondere eines Spannungs-Istwertes, verbunden ist und die Auswerteeinheit (12) zum Ansteuern des Synchrongleichrichters (7), insbesondere zum Ausschalten von Schaltelementen im Nulldurchgang, ausgebildet ist.
(EN)
The invention describes a battery charging device (1) with active rectification, having at least one control apparatus (1a), a rectifier (2), a bridge circuit (5), a transformer (6) and an output rectifier or a synchronous rectifier (7) with an output filter. On the secondary side, for each secondary winding (13, 14) a current sensor (10, 11) or, in the case of one secondary winding, at least one or two current sensors (10, 11) is/are provided which is/are connected to an evaluation unit (12) for transmitting a signal (15), which corresponds to the current value, in particular an actual voltage value, and the evaluation unit (12) is designed to drive the synchronous rectifier (7), in particular to switch switching elements off in the zero crossing.
(FR)
L'invention concerne un appareil chargeur de batterie (1) avec redressement actif comprenant au moins un dispositif de commande (1a), un redresseur de courant (2), un circuit en pont (5), un transformateur (6) et un redresseur de sortie ou un redresseur synchrone (7) doté d'un filtre de sortie. Du côté secondaire, chaque enroulement secondaire (13, 14) est affecté d'un détecteur de courant (10, 11) ou, dans le cas d'un enroulement secondaire, au moins d'un détecteur de courant (10, 11) qui est relié à unité d'évaluation (12) pour le transfert d'un signal (15) correspondant à la valeur de courant, notamment d'une valeur réelle de tension. L'unité d'évaluation (12) est destinée à commander le redresseur synchrone (7), notamment pour mettre hors tension des éléments de commutation dans le passage par zéro.
