  • Medium voltage land connection for marine vessels
    Patent number: 8026629
    Abstract: A device for electrically connecting a polyphase ship distribution network to a polyphase land supply network includes a connection unit for connecting the land supply network. The connection unit is connected to a back-to-back link by way of an input transformer, the link having current converters that are interconnected via at least one direct current voltage circuit. An output transformer is connected downstream of the back-to-back link. The output voltage of the transformer lies between 5 and 50 kV. The output transformer can be connected to the ship distribution network via a single multi-phase interconnecting cable.
