The Power Conversion Module (PCM) plays an important role in a shipboard MVDC system which transforms power from a medium-voltage dc to a low voltage dc bus. In this paper, an isolated modular multilevel dc-dc converter (iM2DC) and a dual active bridge (DAB) converter are designed for a 300 kW PCM converter respectively. The total device rating, passive component size, and conversion efficiency of these two topologies are calculated and compared. In addition, their performance during fault have been analyzed and simulation results are presented.
