A sub module for a converter has first and second subunits. Each subunit has an energy storage device, a first series circuit with two power semiconductor switching units, each with a power semiconductor which can be switched on and off, which have the same forward direction and which are conductive in the direction opposite the forward direction. The first series circuit is connected in parallel with the energy storage device. A connection terminal is connected to the potential node between the power semiconductor switching units in the respective series circuit. The first and second subunits are connected via an emitter connection branch, a collector connection branch, and a switching branch with a switching unit connected between the emitter and collector connection branches. At least one power semiconductor switching unit is arranged in the emitter connection branch or the collector connection branch. |
