To desensitize wireless charging systems (WCSs) to misalignment and to achieve a stable output voltage without using additional control methods, a laminated magnetic coupler (LMC) optimized by the balanced particle swarm optimization (BPSO) method is proposed to improve the performance of WCSs. First, the output characteristics of the LCC-S compensated WCS are analyzed to illustrate the working principle of the LMC. Next, the misalignment characteristics of the LMC, which employs the magnetic integration technique and coil self-decoupling method, are analyzed. Then, the operating principle of the BPSO method is analyzed and used to optimize the LMC in terms of the mutual inductance and anti-misalignment range. Finally, experimental results indicate that the optimized LMC achieves high-efficiency constant voltage charging within a reasonable horizontal misalignment range. When compared to commonly used methods (such as the exhaustive method) for optimizing magnetic couplers, the BPSO method avoids complex algorithms and a heavy computation burden.

为了在不使用额外控制方法的情况下降低无线充电系统（WCS）对错位的敏感性并获得稳定的输出电压，提出了一种通过平衡粒子群优化（BPSO）方法优化的叠层磁耦合器（LMC）来提高WCS的性能。首先，分析LCC-S补偿WCS的输出特性，说明LMC的工作原理。接下来，分析了采用磁集成技术和线圈自去耦方法的LMC的失准特性。然后，分析BPSO方法的工作原理，并根据互感和抗错位范围优化LMC。最后，实验结果表明，优化后的LMC在合理的水平错位范围内实现了高效恒压充电。与优化磁耦合器的常用方法（如穷举法）相比，BPSO方法避免了复杂的算法和繁重的计算负担。
