Abstract

An apparatus for connecting a converter to an AC voltage grid has a grid connection for connection to the AC voltage grid and a converter connection for connection to the converter. The grid connection and the converter connection can be connected to one another via two transformers that are connected in parallel with one another and which, in addition to a primary winding and a secondary winding, are equipped with a tertiary winding. At least one switch is connected in series with each transformer. A connection unit is connected to the tertiary windings of each of the transformers and is configured to connect the tertiary windings to one another.
