Abstract

Problems in high-power contactless power transmission systems using series and parallel resonance capacitors arise from the maximum voltage limit of the series capacitor due to high reactive power. In this study, the characteristics of the reactive power are analyzed using an equivalent circuit and a contactless power transfer system is designed with the reactive power characteristics taken into consideration. The self-inductance and the frequency can be used to determine the distribution of reactive power on the primary side and the secondary side. In addition, the optimal winding number, size of the coil, and the appropriate frequency are investigated through electromagnetic field analysis.
