    Abstract: A converter arrangement and a method of controlling a three-phase converter arrangement connected to a transmission grid are provided. The converter arrangement includes three phase legs and an energy transfer circuit. The method includes providing a varying respective output phase voltage to the transmission grid by selecting energy storage elements of both the phase legs and the energy transfer circuit and connecting the selected energy storage elements to the transmission grid output. The method further includes selecting energy storage elements for performing a transfer of energy between the energy storage elements during the control period.

    Abstract: It is presented a converter cell (10a; 10b) arranged to be used in a high voltage multilevel converter. The converter cell comprises: an energy storage element (16a; 16b) and a plurality of switching elements (S1, . . . , S8). The plurality of switching elements comprises at least one thyristor (S3; S8) and a plurality of transistors (S1, S2, S4; S5, S6, S7). 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 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.
