Abstract

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.

船用MVDC系统中基于双有源桥式变换器和模块化多电平变换器的DC-DC功率转换模块的比较研究

电源转换模块(PCM)在船舶MVDC系统中起着将中压直流电源转换为低压直流母线的重要作用。本文分别为300kw PCM变换器设计了隔离模块化多电平dc-dc变换器(iM2DC)和双有源电桥(DAB)变换器。计算并比较了两种拓扑的总器件额定值、无源器件尺寸和转换效率。此外，还对其故障时的性能进行了分析，并给出了仿真结果。
