Study on a power transmission characteristics of wireless power transmission system by using the novel coil structure with auxiliary resonant tank circuit

Abstract

In decade years, the magnetic coupled resonance have been attracted interest to realize the effective WPT (Wireless power transmission) system under the long distance condition. The novel power transmission coil structure, which is consists of the additional resonant tank circuit nearby and connect with the transmission coil, is proposed in this paper. The effectiveness of additional resonant circuit topology to improve the power transmission efficiency are explained and discussed based on the simulating results.
