- Title
Anti-offset Wireless Power Transfer System Based on Parameter Optimization.
- Abstract
In order to solve the problem of coupling mechanism offset in wireless power transfer system, the S-S and LCC-LCC dual topological wireless power transfer system based on parameter optimization was proposed. Firstly, the output characteristics of S-S and LCC-LCC topological energy transmission channels were analyzed. According to the current output conditions, DDQ coil structures were selected to achieve their decoupling characteristics. Then, in order to have better anti-offset characteristics, a parameter optimization method was proposed to optimize the parameters of compensation network. Finally, an experimental prototype was built to verify the feasibility of the theory. The experimental results show that the maximum offset of the optimized coupling mechanism was up to 160 mm, the current gain fluctuation range was 0.163 1~0.180 1, the current fluctuation ratio was ±4.9%, and the system efficiency was up to 89.47%.
