Abstract

A voltage source converter (30) comprises: first and second DC terminals (32,34) for connection to a DC electrical network (44); and a converter limb (36) directly connected between the first and second DC terminals (32,34), the converter limb (36) including: an AC terminal (42) for connection to an AC electrical network (46); a first limb portion (38) directly connected between the first DC terminal (32) and the AC terminal (42); and a second limb portion (40) directly connected between the second DC terminal (34) and the AC terminal (42), wherein only one of the first and second limb portions (38,40) includes a multilevel converter block (52), the other of the first and second limb portions (38,40) includes a switching block (48), the switching block (48) is switchable to selectively permit current flow in at least one direction in the corresponding limb portion (38) and inhibit current flow in at least one direction in the corresponding limb portion (38), and at least one of the first and second limb portions (38,40) is controllable to control the configuration of an AC voltage waveform at the AC terminal (42).
