Abstract

See full text

A control circuit (20) comprises: first and second terminals (22,24) for respective connection to first and second power transmission lines (26,28); a current transmission path (30,32) extending between the first and second terminals (22,24), the current transmission path (30,32) including at least one module (36), the or each module (36) including at least one energy storage device, the current transmission path (30,32) including at least one inductor (38); a control unit (46) which selectively removes the or each energy storage device of the or each module from the current transmission path (30,32) to modulate a voltage across the or each inductor (38) in a filtering mode to modify current flowing through the current transmission path (30,32) and thereby filter one or more current components from the power transmission lines (26,28); and at least one energy conversion element, wherein the control unit (46) selectively removes the or each energy storage device of the or each module (36) from the current transmission path (30,32) in an energy removal mode to cause current to flow from the power transmission lines (26,28) through the current transmission path (30,32) and into the or each energy conversion element to remove energy from the power transmission lines (26,28).
