HIGH-FREQUENCY LINE FILTER

In a high-frequency line filter for a converter, the converter has three phase connections for receiving a three-phase alternating signal from a three-phase voltage network and is adapted to convert the received three-phase alternating signal into an output signal for a load. The high-frequency line filter includes: a first filter path for establishing a conductive connection between a first phase connection of the three phase connections and a ground connection; a second filter path for establishing a conductive connection between a second phase connection of the three phase connections and the ground connection; and a third filter path for establishing a conductive connection between a third phase connection of the three phase connections and the ground connection. The high-frequency line filter includes a series connection of a pulse-proof capacitor and a parallel connection of at least two Y capacitors, the series connection being provided in each filter path.
