摘要： One circuit includes first and second primary terminals for connection to first and second power transmission lines and a current transmission path extending between the primary terminals and having current transmission path portions separated by a third primary terminal. A first current transmission path portion includes at least one primary switching element connected in series between the first and third primary terminals, the second current transmission path portion includes an energy conversion block connected between the second and third primary terminals, and the energy conversion block includes at least one primary energy conversion element for removing energy from the power transmission lines. The control circuit further includes a converter limb connected across the second and third primary terminals that includes an auxiliary converter. The control circuit further includes a control unit which controls the auxiliary converter to selectively provide a voltage source.

摘要： A voltage source converter includes three branches connected at a first end to a junction to form a star configuration, the second end of each branch defining a DC terminal, the second ends of the second and third branches being connectable to a first DC voltage, and the second ends of the first and second branches being connectable to a second DC voltage. The first and second branches include primary switching elements, and the third branch includes a primary inductive element. The converter includes a converter limb connected in parallel with one of the first and second branches, the converter limb including a chain-link auxiliary converter including multiple series-connected modules controllable to selectively provide a voltage source to modify a branch voltage across the branch connected in parallel with the converter limb, each module including at least one secondary switching element and at least one energy storage device.
