Abstract

The invention relates to a method for suppressing interference signals in at least one supply line, especially in at least one supply line for high-voltage sources in a powertrain of an electric vehicle. The at least one supply line has at least two inductive transformers coupling an amplifier circuit to the supply line in a galvanically insulated manner. The at least two inductive transformers each have a primary circuit and a secondary circuit, each of the at least one primary circuits being associated with the supply line and each of the at least one secondary circuits being associated with the amplifier circuit (2). An inductance of the at least one primary circuit of a first transformer is formed in the at least one supply line to suppress interfering signals. A signal from the supply line is tapped by means of a second transformer and supplied to an input of the amplifier circuit (2). The inductance of the at least one primary circuit of the first transformer is increased by the amplifier circuit (2) supplying a correction signal to the first transformer and the amplifier circuit (2) producing the correction signal depending on the interference signals from the signal of the second inductive transformer by amplification.
