Next generation of MVDC ships will be characterized by a power-electronics-based power distribution system. Since onboard power generation is in AC, special attention is pointed at the AC/DC interface converters forming the MVDC bus of the shipboard power distribution system. In this paper preliminary design of two AC/DC power conversion stages and their voltage control is provided. Besides the respective local control systems, a coordination strategy is required between the two AC/DC power conversion stages in order to achieve loads power sharing. In the proposed case study, a MVDC bus control based on the droop control theory is adopted. Simulation results support the proposed coordination strategy.
