谐振式WPT耦合线圈形状设计与参数优化
|
摘要
耦合线圈是无线电能传输系统的核心部分,它直接影响着电能传输的性能,线圈的最佳形状与参数亟需深入研究。本文针对无线电能传输系统构建了高频电路模型,推导出耦合电能传输系统的功率与效率表达式,随后借助COMSOL Multiphysics对平面圆形、平面方形与螺旋筒形三种常见形状进行了仿真分析,得出不同距离下功率与效率的曲线图。确定了耦合线圈的最佳形状,并在最佳形状下进行不同线圈参数仿真,得出最佳谐振线圈参数变化规律,即线圈直径和线径越大,而且匝间距越小,线圈的品质因数越高。本文为无线电能传输系统的优化与设计提供了依据与参考。
Coupling coil is the key of a wireless power transfer(WPT) system, which affects the capability of wireless power transfer system. So the shape and structure optimization of the coupling coil is important. In this paper, a high-frequency circuit model is constructed for wireless power transfer system, and the power and efficiency expression of the coupled energy transfer system is deduced. The COMSOL Multiphysics is used for the simulation of three common shapes including plane circle, plane square and spiral barrel. The variations of power and efficiency at different distances are compared. The optimal shape of the coupling coil is given. And the simulation applying different structure parameters is achieved with the optimal shape to obtain the optimum resonance coil parameters. We find that the larger the coil diameter or wire diameter and the smaller the pitch, the higher the quality factor of the coil. This paper provides the basis and references for the optimization of wireless power transfer system.
