철도 전력망을 이용한 EV용 충전방식 설계 및 시스템 설치 분석 연구

초록

In this paper, a study on the charging method appropriate for establishing an EV(Electric Vehicle) charging infrastructure using railway power grid is described. Currently, EVs are being developed with the emerging need of environmental transportation methods regarding depletion of fossil fuel and pollution. However, growth of EVs is being delayed due to insufficient charging infrastructure and one solution to this matter is utilizing the railway power grid. In this paper, design of an AC-DC convertor and phase transition full-bridge convertor is proposed to check efficiency of EV charging infrastructure configuration, AC/DC charging methods, and high capacity DC charging methods by simulating the effect of increasing EVs being charged. In addition, charging facilities appropriate for establishing an EV charging infrastructure using railway power grid was proposed.
