Analysis of the topology of „Shore to Ship” systems - power electronic connection of ships with land

The possibility of building efficient and universal systems for the use of electricity land network by ships berthed in the port appeared along with the development of power electronic technologies. The need to connect ships to the land network is primarily related to ecological reasons. The choice of the appropriate topology by the investor (usually port authorities) is mainly connected with ensuring high quality of electricity provided to the ship and local conditions. The article reviews topologies of power electronic system (possible to use) for connection of ships with the land network - their disadvantages and advantages.
