The invention relates to a modular switching unit of a high-voltage DC power converter, comprising a base module (18) having a first switching device (2), a second switching device (3), a first capacitor (4) and a second capacitor (5), the first switching device (2), the second switching device (3), the first capacitor (4) and the second capacitor (5) being mounted on a chassis (15), characterized in that the first capacitor (4) and the second capacitor (5) are mounted on the chassis (15). The base module (18) is adapted to receive at least three different groups of busbars, each group of busbars comprising a plurality of busbars for interconnecting the first switching device (2), the second switching device (3), the first capacitor (4) and the second capacitor (5), the first cell terminal is connected to the second cell terminal to form one of two parallel half-bridge circuits between the first cell terminal and the second cell terminal, two series half-bridge circuits between the first cell terminal and the
