Research and optimization design of transmitting and receiving system in wireless power transfer via coupled magnetic resonances

Abstract

This paper presents a research and optimization design of transmitting and receiving system in wireless power transfer via coupled magnetic resonances. The system connects the coil to the metal obstruction, which helps to eliminate the negative impact of metal obstacles on the wireless power transmission system and improve system transmission efficiency and direction compatibility. The influence of the coil connected with the metal obstacle on the resonance frequency of the system is studied and the optimized design has improved the transmission efficiency and direction compatibility compared with the metal-free systems is proved by establishing a universal wireless power transmission experimental device.
