Abstract
In this paper, we have investigated effects of lateral and angular misalignment on the wireless power transfer (WPT) system. The parameters of electric circuit model and the magnetic field distribution was obtained under misalignments. Coupling coefficient, transmission efficiency, current in the coil were analyzed. Also, the magnetic field perpendicular to the receiving coil surface was calculated. The results can show the insight to characterize the type of misalignments and its quantitative evaluation, so the transmission efficiency can be improved, and an overcurrent can be prevented in system by adapting a proper compensation topology.
