Zusammenfassung:A switchgear cell is disclosed having a first energy store and a second energy store connected in series therewith, having a first, second, third and fourth power semiconductor switch, which are connected in series, wherein the first, second, third and fourth power semiconductor switch are in each case one drivable bidirectional power semiconductor switch with a controlled unidirectional current-conducting direction. The first power semiconductor switch is connected to the first energy store, and the fourth power semiconductor switch is connected to the second energy store. A third energy store is connected to the junction between the first and the second power semiconductor switch and the junction between the third and the fourth power semiconductor switch.
