Abstract
The invention relates to a device for rejecting interference signals in bipolar voltage sources, in particular in high-voltage sources in a powertrain of an electric vehicle, wherein an amplifier circuit is provided, with an input stage the input of which is symmetrically connected by means of an electrically isolated tap to a positive power line and a negative power line of a voltage source in order to tap an interference signal, and with an output stage, actuated by the input stage, the output of which is symmetrically connected in each case via an output capacitor to the positive power line and the negative power line, in order to feed in a correction signal.
