Beschreibung
Zusammenfassung:	The invention relates to a power converter (200), in particular of a wind energy installation for feeding electrical power into an electrical supply network, at least comprising: a multiplicity of rectifiers (210) which are connected to a first AC voltage network (125) in order to convert a first AC voltage into a DC voltage, a DC voltage intermediate circuit (220) which is connected to the multiplicity of rectifiers and is configured to carry the DC voltage, and a multiplicity of inverters (230) which are connected to the DC voltage intermediate circuit and to a second AC voltage network (126) in order to convert the DC voltage into second AC voltage, and a switchable converter module (240), at least comprising: a converter (242) connected to the DC voltage intermediate circuit (220) and a switching unit (244) which is connected to the converter, can be connected to the first and the second AC voltage network and can be connected to the first AC voltage network such that the converter is in the form of a rec
