The use of topology of IHBI inverters in parallel operation of ship generating sets with PMSG generators

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.
