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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transformer connection apparatus","description":"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.
