Document Type and Number:
WIPO Patent Application WO/2023/060647
Kind Code:
A1
Abstract:
Disclosed in the present invention are an optimization method and apparatus for a coupling structure for multiple repeating coils in a long-distance WPT system. The optimization method comprises: determining all permutation and combination models according to the different sizes and types of coils; establishing WPT system efficiency models under different permutation and combination models; according to the WPT efficiency models, analyzing factors that affect improvement of the efficiency of a WPT system under coils of different sizes; optimizing the distance between adjacent coils by means of optimal designs under the different permutation and combination models and in view of various factors; and by means of comparing the efficiencies of the different permutation and combination models after analysis and optimization, determining permutations and combinations under which the WPT system under the coils of different sizes has the optimal efficiency. In the method, by means of optimizing the distance between adjacent coils, permutations and combinations under which the optimal efficiency is achieved are determined, such that a system always operates in an efficient state during an energy transfer process, thereby effectively ameliorating the problem of lower efficiency during a medium-long-distance wireless power transfer process.
