A voltage source converter (10) for use in three-phase high voltage DC power transmission and reactive power compensation. The voltage source converter (10) comprises three converter limbs (12,14,16) connected in a bridge circuit arrangement wherein each of first and second converter limbs (12,14) includes a multilevel converter (18) and a third converter limb (16) includes a capacitor (20) on each side of a series AC phase connection (22). The multilevel converters (18) are controllable to synthesize waveforms at series AC phase connections (24,26) of the first and second converter limbs (12,14). |
