摘要

为了设计高效率的WPT系统，我们根据l形集总常数双元件匹配电路的质量因子和输入/输出阻抗(复杂阻抗而非简单电阻)来表示插入损耗。推导公式明确，从而使高效匹配电路的分析设计具有清晰的视角。文中还给出了用该公式进行分析的一些实例，揭示了一些有趣的事实。

Power loss formula for impedance matching circuits dedicated to wireless power transfer

To design high efficiency WPT systems, we formulate the insertion loss in an L-shaped lumped-constant two-element matching circuit in terms of the elements' quality factors and the input/output impedances which are complex impedances rather than mere resistances. The derived formula is explicit, and thus enables analytical design of high-efficiency matching circuits with a clear perspective. Some analysis examples by the formula are also given, which reveal interesting facts.
