    Patent number: 7453330
    Abstract: A line filter has a filter unit, which has an input and an output and also a current-compensated choke and a capacitance network. The choke has several phase windings on a common core. Each phase winding is connected in series with a phase conductor. The capacitance network has capacitors, which are each connected between a phase conductor and a neutral conductor. Another choke is provided in series to the neutral conductor, which is wound separately from the core.
