提出了一种无线电力传输（WPT）设备磁芯的拓扑优化方法。在此优化中，WPT的线圈和磁芯形状由高斯基函数表示。采用遗传算法和三维有限元分析对其进行序贯优化，使WPT器件的耦合系数最大化。此外，提出了一种鲁棒优化方法，使线圈在不对准的情况下保持最大的连锁磁链。计算和实验结果表明，优化后的器件性能优于传统器件。
This paper presents the topology optimization of the magnetic core for a wireless power transfer (WPT) device. In this optimization, the coil and magnetic-core shapes for WPT are represented by the Gaussian basis functions. They are sequentially optimized using the genetic algorithm and 3-D finite-element analysis so that the coupling coefficient of the WPT device is maximized. Moreover, a robust optimization method is proposed to keep the interlinkage flux as large as possible against misalignment in the coils. It is shown by the computational and experimental results that the optimized device outperforms the conventional devices.
