It is presented a converter cell (10,10a,10b) arranged to be used in a high voltage multilevel converter. The converter cell comprises: an energy storage element (16,16a,16b); and a plurality of switching elements (S1,S2,S3,S4,S5,S6,S7,S8). The plurality of switching elements comprises at least one thyristor and a plurality of transistors; and each one of the at least one thyristor (S3,S8) 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 thyristors is in a continuous conducting state. A corresponding multilevel converter and a method are also presented. |
