Abstract: Integrated power systems (IPSs) with medium voltage direct current (MVDC) distribution are gaining importance in civil and defense marine vessels as they promise to provide cleaner, more reliable operation of vessels along with reduced fuel consumption. The integration of battery energy storage systems (BESSs) in the MVDC distribution system enables peak shaving of generators, optimal scheduling of generators, and near instantaneous power reserve. In this paper, an isolated bipolar dc-dc converter is presented which interfaces the BESS with the bipolar dc distribution bus. The proposed converter uses high frequency transformer isolation which helps in protecting the BESS against rapid discharge in the event of short circuit faults on the dc bus. Detailed steady-state analysis of the proposed converter is presented in this paper. A closed loop control system is developed in the MATLAB®/Simulink simulation platform which regulates the output of the isolated bipolar converter to its reference value. The dynamic performance of the converter is demonstrated with load variations on both the positive and negative buses. The battery discharge limiting capability is also verified.
