Abstract:
A converter includes first and second DC terminals for connection to a DC network, limb(s) connected between the first and second DC terminals, and a controller. Each limb includes a phase element and DC side sub-converter(s). The phase element has switching elements and AC terminal(s) for connection to an AC network, the switching elements being switchable to selectively interconnect a DC side voltage at a DC side of the phase element and an AC side voltage at an AC side of the phase element, The DC side sub-converter(s) connected to the DC side of the phase element. The controller selectively controls the switching elements and the operation of each DC side sub-converter as a voltage synthesiser. The controller also controls the switching elements to provide a blocking voltage to limit or block the flow of a fault current between the AC and DC networks and through each limb.

Claim (Index 1):
A converter comprising first and second DC terminals for connection to a DC network, the converter further including at least one limb connected between the first and second DC terminals, the or each limb including:\n a phase element having a plurality of switching elements and at least one AC terminal for connection to an AC network the plurality of switching elements configured to be switchable to selectively interconnect a DC side voltage at a DC side of the phase element and an AC side voltage at an AC side of the phase element, each switching element of the phase element configured to have forward and reverse voltage blocking capabilities; and at least one DC side sub-converter connected to the DC side of the phase element, the or each DC side sub-converter configured to be operable as a voltage synthesiser, wherein the converter further includes a controller configured to selectively control the switching of the switching elements of the phase element of the or each limb and configured to selectively control the operation of the or each DC side sub-converter of the or each limb as a voltage synthesiser, and wherein the controller is configured to control the switching of the switching elements of the phase element of the or each limb to provide a blocking voltage to limit or block the flow of a fault current between the AC and DC networks and through the or each limb.
