A multilevel converter cell (DVC) comprises a first section (SEC1) with a first group of series connected switching units in parallel with a first energy storage element (C1), where a junction between a first and a second switching unit (SW1, SW2) forms one cell connection terminal (TEDVC1), a second section (SEC2) with a second group of series connected switching units in parallel with a second energy storage element (C2), where a junction between a third and a fourth switching unit (SW3, SW4) forms another cell connection terminal (TEDVC2), and an interconnecting section (ISEC) with a third group of series-connected switching units comprising a fifth, sixth and seventh switching unit (SW5, SW6, SW7), with the fifth and sixth switching units (SW5, SW6) connected in parallel with the first energy storage element and the sixth and seventh switching units (SW6, SW7) connected in parallel with the second energy storage element (C2). |
