One of the methods to improve the efficiency of the ship’s propulsion is the increase of efficiency in ship generators by using permanent magnet synchronous generators (PMSG - Permanent Magnet Synchronous Generator). Due to the lack of voltage regulator in PMSG, it is necessary to use power electronic converters to maintain a constant voltage level. One of the modes of operation for a ship’s power plant is a parallel work of generating sets. In the parallel work, there are problems in the fluctuation of active and reactive electrical power between generators. The article presents the concept of using inverters in the IHBI topology, which enables the parallel operation of generating sets with PMSG generators. This solution enables the adjustment of the flow of active and reactive powers between generating sets.

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.
