Abstract: A DC cable for high voltages has at least an inner conductor (8) surrounded by an insulating layer (10) configured to take the voltage to be taken between the conductor and the surroundings of the cable. The insulating layer is formed by a plurality of superimposed film-like layers (12) of insulating material each having isolated areas of metal (13) on top thereof. The metal areas of consecutive such film-like layers are at least partially overlapping each other as seen in the radial direction of the cable so as to create a large number of small capacitors in said insulating layer of the cable.

Abstract: A Voltage Source Converter of M2LC-type has a series connection of switching cells (7), in which each switching cell has on one hand at least two semiconductor assemblies connected in series and having each a semiconductor device of turn--off type and a free-wheeling diode connected in parallel therewith and on the other at least one energy storing capacitor (20). The series connection of switching cells has one first end (61) connected to a direct voltage pole (5) on high voltage potential and an opposite end (62) connected to a phase output (10) of the converter. An arrangement (70) is configured to connect the phase out-put (10) to another said pole (6) on neutral voltage potential on a direct voltage side of the converter and to deliver voltage pulses to said phase output being both positive and negative with respect to said neutral potential.
