Abstract
A voltage source converter comprises a converter arm extending between two terminals each terminal being connectable to a or a respective electrical network, the converter arm including a valve that includes at least one module, the or each module being operable to selectively provide a voltage source; and a controller programmed to selectively operate the valve to clamp a voltage at either or both of the two terminals and thereby operate the valve as a current limiter to limit a selected current flowing in the converter arm at or below a fixed or variable current threshold.
