Abstract
It is presented a converter cell () arranged to be used in a high voltage multilevel converter. The converter cell comprises: an energy storage element () and a plurality of switching elements (S, . . . , S). The plurality of switching elements comprises at least one thyristor (S; S) and a plurality of transistors (S, S, S; S, S, S). Each one of the at least one thyristor (S; S) is provided in a position for a switching element in the converter cell where, during normal operation of the converter cell, the at least one thyristor is in a continuous conducting state. This reduces the power losses of the converter cell. A corresponding multilevel converter and a method are also presented.
