Abstract (en)
[origin: WO2007041729A1] 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.
