摘要：

The wide-scale adoption of electric vehicles may have the capability of efficient and fast charging while the car is in motion or dynamic wireless power transfer (DWPT) technology. Magnetic pad and compensation topology are two major factors affecting the amount of power transfer and efficiency of dynamic wireless power transfer. This article presents an iterative approach to designing magnetic pads and optimization of a double-side LLC compensation network. The optimization of coil pad was performed using a parametric sweep. Finite-element modeling in ANSYS Maxwell 3D was developed to achieve a desired value of self and mutual inductance of the coils. The effect of coil misalignment was also analyzed. A case study of a 3-kW dynamic wireless power transfer system was simulated under different loads using MATLAB/Simulink to verify the features of the proposed system. The system showed DC-DC efficiency as high as 97.80% with constant voltage output.
