1. A converter station comprising:

  • a voltage source converter (VSC1) coupled between a direct current link (W1, W2) and an alternating current network (N1) in a high voltage direct current transmission system; and

    a filter block (F1) coupled between the voltage source converter and the alternating current network for filtering current harmonics in the alternating current network;

    characterized in thatthe resistive part of the second filter block (F1) comprises a common ungrounded electrical zero between phases.
