1. A power converter, comprising:
a first connection, a second connection, a third connection and a fourth connection;
energy store connections, to which an energy store is connectable;
four inverter bridge branches formed from semiconductor switching devices;
wherein the inverter bridge branches each have a center tap, wherein a respective center tap is assigned to one of the connections, and
wherein the inverter bridge branches are connected and are controllable in such a manner that electrical energy is transmitted bidirectionally between the energy store connections and the first connection, the second connection, the third connection and/or the fourth connection; and
a control unit designed to control the semiconductor switching devices of the inverter bridge branches, wherein
the control unit is designed, in a first operating mode, to control the semiconductor switching devices of the inverter bridge branches in such a manner that one connection of the four connections forms a neutral conductor of an AC voltage grid and the three other connections of the four connections form phase conductors of the AC voltage grid.
