Abstract: A control circuit (20) comprising: first and second terminals (22,24) for respective connection to first and second power transmission lines (26,28); a current transmission path extending between the first and second terminals (22,24) and having first and second current transmission path portions (30,32) separated by a third terminal (34), either or both of the first and second current transmission path portions (30,32) including at least one module (36), the or each module (36) including at least one energy storage device; an auxiliary terminal (42) for connection to ground or the second power transmission line (28); an energy conversion block for removing energy from the power transmission lines (26,28), the energy conversion block extending between the third and auxiliary terminals (34,42) such that the energy conversion block branches from the current transmission path, the energy conversion block including at least one energy conversion element (44); and a control unit (46) which selectively removes the or each energy storage device from the current transmission path.
