전기자동차용 무선 전력 충전의 적정 선정을 위한 자기 공진 회로구조의 비교 분석

Abstract

In this paper, four circuits of magnetic resonance circuit systems for improving the performance of wireless power charging for electric vehicles were compared and analyzed. Currently, wireless charging is widely used in real life and commercialized, and a wireless charging method is being studied to compensate for the problems of the wired charging method of electric vehicles. In order to wirelessly charge an electric vehicle, a magnetic resonance method is used, and to compare the efficiency of the most basic four magnetic resonance circuit system structures, parameters are obtained through the design formula of the magnetic resonance circuit system, and the efficiency of each magnetic resonance circuit system are compared and analyzed through PSIM.
