Abstract
In a filter circuit (6) with a low-pass filter (7), the output of the low-pass filter (7) is regenerated over a reverse current diode (11) with the input of the low-pass filter or of a further low-pass filter (8) pre-connected to the low-pass filter (7). A circuit arrangement includes such a filter circuit (6) and a battery charger circuit (1) with a battery (2) and a d.c. generator (A).
Claims4
Circuit arrangement with a filter circuit with a low-pass filter, where the output of the low-pass filter is regenerated over a reverse current diode with the input of the low-pass filter or of a further low-pass filter pre-connected to the low-pass filter, wherein the circuit arrangement comprises a battery charger circuit, which includes a battery and a d.c. generator, an internal resistance of the reverse current diode being adapted to an internal resistance of the battery in such a way that a maximum current through the reverse current diode is not exceeded.
