: Unlike conventional propulsion systems that use low-frequency transformers, propulsion systems for railway vehicles using solid-state transformers include isolated DC/DC converters to improve power density and system quality. As DC/DC converters have different characteristics, it is necessary to compare and analyze each DC/DC converter when applying to solid-state transformer. Therefore, in this paper, the design process of DAB and CLLC converters, which are the most widely used bidirectional DC/DC converters, is introduced for application to SST system. After that, design parameters and loss of two converters are analyzed and compared through PLECS simulation.
