Abstract

In a VSC-converter for converting direct voltage to alternating voltage and conversely at least one phase leg (2) is arranged according to a NPC-connection. At least two of the four current valves (3-6) and the clamping rectifying members (10, 11) thereof are arranged close to each other and so that commutation currents generated on commutation of the converter therein will flow in substantially opposite directions.
