Abstract

A voltage source converter comprises a number of converter modules, one for each phase of an AC waveshape to be generated, connected between two DC terminals and each comprising a first and a second DC connection point (DCCP1, DCCP2), a string of director switches (SI, S2), the midpoint of which provides a third connection point (CP3), and waveshaper branches (WSB1, WSB2) connected in parallel with each other as well as to the string, each waveshaper branch (WSB1, WSB2) comprising submodules (SMA1, SMA2, SMA3, SMA4, SMB1, SMB2, SMB3, SMB4) and being connected to an AC connection point (ACCP1, ACCP2) provided for the branch, wherein at least one of the AC connection point and the third connection point is provided for connection to a corresponding phase of an AC link, the first and second waveshaper branches produce two similar waveshapes for the AC link and the switches change the way the waveshapes are applied to connection points.
