PCT No. PCT/SE95/00782 Sec. 371 Date Oct. 10, 1996 Sec. 102(e) Date Oct. 10, 1996 PCT Filed Jun. 26, 1995 PCT Pub. No. WO96/01517 PCT Pub. Date Jan. 18, 1996An HVDC transmission including at least two converters. Each converter is adapted for connection between a three-phase alternating-voltage network. At least a first converter has ac leads for connection of the first converter to the alternating-voltage network without the use of a separate winding transformer. A dc link is common to the converters. A zero-sequence inductor connection is arranged in the ac leads of the first converter and designed such that the zero-sequence inductor connection exhibits a high impedance to zero-sequence currents and a low impedance to positive-sequence currents.
