<p>A VSC converter has each current valve (7, 10) of a phase leg (4) formed by a plurality of units (22) of semiconductor elements and rectifying members piled on top of each other in at least one stack. The phase leg is constructed according to the ribbon cable principle with the phase leg formed by such stacks arranged side by side in pairs at small distances (d) and running to and fro and having a cooling plate (23) of electrically conducting material arranged between and connected in series with each unit in the stacks. <IMAGE></p> |
