Abstract
A method is disclosed for supplying external energy to electrical on-board power networks of ships, with there being at least one generator, one converter and electrical loads in the ship's on-board power network. In at least one embodiment of the method, the converter (shore connection converter) on board the ship, for transfer into the on-board power network, is fed by a connectable external current source with current of a different frequency and voltage to that of the on-board network and the current is converted in the converter semiconductors into current with the voltage, and the frequency of the on-board power network and fed to the on-board power network.

Method for supplying current to at least one electrical on-board power networks of a ship including at least one generator, at least one converter and electrical loads in the ship's on-board power network, the method comprising:
- receiving at a shore connection converter located on board the ship, for transfer into the at least one electrical on-board power network and via a connectable external current source on an input side, a current with a frequency and a voltage differing from that of the at least one electrical on-board power network;
- and
- converting the current in the shore connection converter into current with a voltage and a frequency of the at least one electrical on-board power network;
- and
- supplying the converted current to the at least one electrical on-board power network, wherein, in ships with an electrical drive system, at least one converter of the drive system is used as the shore connection converter.
