Abstract
The disclosure relates to an inverter including a first bridge branch with a first phase output, a second bridge branch with a second phase output, a third bridge branch with a third phase output, wherein the phase outputs of the bridge branches can each be connected to a phase conductor of a three-phase power distribution network. The inverter is configured, in a normal operating mode of the three-phase power distribution network and/or of a higher-level power supply network connected thereto, to connect the phase outputs to the relevant phase conductor and, in the event of a fault in the three-phase power distribution network and/or in the higher-level power supply network connected thereto, to disconnect the three-phase power distribution network from the higher-level power supply network via a network disconnector, to disconnect the first phase output from the first phase conductor by means of a switching unit and to connect same to a neutral conductor of the three-phase power distribution network, and to establish a neutral potential for the neutral conductor via the first bridge branch. The disclosure further relates to a method for operating an inverter of this kind.
