Abstract

Against the backdrop of the rapid development of the global electric vehicle industry, wireless charging technology has gradually become a focal point of attention in both academia and industry due to its convenience and safety. However, a prominent challenge in practical applications is the positional misalignment between charging coils, which often leads to a significant decline in power transmission efficiency, thereby constraining the widespread adoption of this technology. In response to this practical issue, this paper proposes and designs a simple anti-misalignment control algorithm based on the proportional control principle. By establishing a MATLAB/Simulink simulation platform, the algorithm can sense the degree of misalignment between coils in real time and dynamically adjust the driving current of the transmitter, thereby effectively compensating for energy losses caused by misalignment. Simulation results confirm that, under varying degrees of misalignment scenarios, the proposed control strategy consistently enhances the charging efficiency and overall robustness of the system. This study not only offers an economical and practical technical approach to addressing misalignment issues in wireless charging but also provides valuable references for engineering practice and educational demonstrations in related fields.
