An installation for transmission of electric power between a dc-voltage side of a VSC converter (1) and a three-phase ac-voltage network (2), connected to the ac-voltage side of the converter, exhibits a transformerless connection between a phase terminal (19, 19', 19'') of the respective phase leg of the converter and the three-phase ac-voltage network. The transformerless connection is formed by connecting the respective phase terminal of the converter to the respective phase of the ac-voltage network through a phase conductor (27-29) wound around an iron core (30) that is common to the other two phase conductors and that is dimensioned to essentially take care of zero-sequence currents generated during the pulse-width modulation of the current valves includes in the converter. |
