Abstract: How to charge more conveniently is a challenging problem, which affects people's daily life from two aspects of distance and portability. Considering the coil characteristics and coil size, the transmission system must adapt to these variables. Planar and layer wound coils are two widely used transmission coils. However, there is no further analysis on the layer wound coil in the previous publications. Compared with the planar structure, the layer wound structure has many advantages, such as longer transmission distance, faster energy accumulation speed. Therefore, there are more energy requirements in the scenarios of high-power electric locomotive and electric vehicle charging and household appliances. In addition, a new reference variable (coil turn spacing) is added in this paper, which is used to further optimise the system. Therefore, it is of great significance for the research of radio power transmission system.

Keywords: wireless power transmission; layer wound structure.
