摘要：
The magnetic coupling structure is the core part of a magnetically coupled resonant wireless power transfer system. The establishment of an analytical model, the analysis of misalignment performance and the optimization of structure play a key role in the study of the transmission performance of the whole system. Consequently, the circular planar pad was taken as the research object. Firstly, a new mutual inductance analytical model was derived for the magnetic coupling structure without or with dislocation using the theory of electromagnetic field. Then, the mutual inductance characteristics of the magnetic coupling structure in the presence or absence of ferrite were studied and the concept of the stable variation range of mutual inductance was proposed, and the coil structure was optimized. Finally, in order to test the misalignment performance of the magnetic coupling structure, an experimental prototype with transmission power of 1 000 W was built. The measurement and operation results show that the mutual inductance analytical model and the misalignment performance analysis method of the magnetic coupling structure established in this paper have high accuracy and effectiveness. The results play a positive role in promoting the analysis and performance improvement of wireless charging system. © 2020, High Voltage Engineering Editorial Department of CEPRI. All right reserved.
