Abstract (en)
[origin: WO2019174732A1] A voltage source converter (12) converts between AC and DC is connected between at least three DC terminals (DC1, DC2, DC3) and comprises three parallel AC phase modules each comprising an corresponding AC terminal (ACA1, ACB1, ACC3), where each comprises a lower converter arm (1a) connected between a first DC terminal (DC1) and the AC terminal (ACA1), a first upper converter arm (ua0, ua1) connected between the AC terminal (ACA1) and a second DC terminal (DC2) and a second upper converter arm (ua2), the lower and first upper converter arms forming a phase leg and the second upper converter arm stretching out from a connection point (CP) on the phase leg to a third DC terminal (DC3), where the phase leg comprises submodules (CLAL, CLAC, CLAB1) for supplying a first DC voltage, while the second upper converter arm comprises circuitry (CLAB2) for, together with the submodules between the first connection point and the first DC terminal, providing a second DC voltage and the first DC terminal is adapted to be connected to ground.
