6. Abstract
: Solid-state transformers (SST), alternatives to conventional oil-immersed transformers, are cutting-edge technology with advantages of high efficiency, high power density, small volume, and low weight. To design the SST system, proper topology considering target parameters of applications should be selected and a control scheme must be designed for stable DC output control. In this paper, to construct an SST system with the objective of practical implementation on domestic urban railway vehicles, optimal topology is configured with appropriate semiconductor devices, and control architecture is developed. The effectiveness of designed system is demonstrated by simulations and results of loss analysis under operation conditions of urban railway vehicles are provided.
