Abstract

Aiming at short distance and weak misalignment of inductively coupled power transmission system and the problem of resonant coupled structure susceptible to interference

a cooperative operating coupler featuring tight-strong coupling is proposed innovatively. The transmission performance varying with coupling coefficient and quality factor is studied by developing a mathematical model of dynamic wireless charging system. Based on finite element simulation

the transmission efficiency and power are analyzed. In order to improve the anti-misalignment capability and reduce the electromagnetic radiation

magnetic shielding component is added to the receiving coil. A prototype is built to verify the feasibility of the proposed structure. The results indicate that the proposed coupler has high dynamic transmission performance

the transmission efficiency reaching 93. 9% at 85 kHz. This work is supported by National Natural Science Foundation of China(No. 51677132)
