60kHz 자기 공진형 무선전력전송 시스템의 회로 모델링 및 비교 실험

Abstract

In this paper, circuit model of magnetic resonant wireless power transmission system is analyzed. In the area of wireless power transmission, most studies are concentrated in analyzing electro-magnetic field using numerical method. However, the numerical methods have difficulties in representing the entire system. Circuit model of wireless power transmission system makes the analysis fast. The circuit model is calculated using mutual inductance of different distance. To verify the validity of the circuit model, magnetic resonant wireless power transmission system of 60kHz was experimented and comparatively analyzed with the circuit model. As a result, it was observed that the voltage prediction of circuit model was similar to the experimental result.
