Abstract
A VSC converter has each current valve of a phase leg formed by a plurality of units of semiconductor elements and rectifying members, located on top of each other forming at least one stack. The phase leg is constructed according to the flat cable principle with the phase leg formed by such stacks arranged side by side in pairs at small distances (d) running back and forth. A cooling plate of electrically conducting material is arranged between each unit in the stacks.
