本論文提出一具有水平與角度偏移抵抗能力之混合耦合四線圈架構 (Mixed Coupling Four-Coil Structure, MC4C)，而其可被應用於生醫植入裝置或消費型電子裝置之無線能量傳輸應用。

透過分析磁耦合與電耦合之互補性及四線圈架構的高傳輸效率特性，本文所提出的混合耦合四線圈架構得以在水平與角度錯位下相較傳統磁耦合四線圈架構仍保有良好的功率傳輸效率。此外，本文提出一個完整分析模型後，經適當簡化藉由數學軟體驗證MC4C之電路模型其可完整且準確的描述了其功率傳輸效率與錯位容忍力特性。

最後，本文所提出之架構其功率傳輸效率在傳輸距離D = 40 mm時傳輸效率為46%，在傳輸距離為50 mm時傳輸效率為32%。S21於水平錯位DL = 50 mm時MC4C的衰減率為41 %小於傳統四線圈佳構的衰減率58 %。於角度錯位 = 72 deg時本論文所提出之架構的衰減率為7 %小於傳統四線圈佳構的衰減率32 %。透過比較衰減率間接的驗證本文所提出之架構有較佳的錯位容忍力。

In this thesis, a mixed coupling four-coil (MC4C) structure be proposed to improve the lateral and angular misalignment tolerance in this thesis for the applications of biomedical implants or consumer electronics. The MC4C structure applies both the complementarity of magnetic coupling and electrical coupling and the high power transfer efficiency (PTE) of a four-coil structure. Compared with the traditional magnetic-coupled four-coil structure under the existence of lateral and angular misalignment, the MC4C structure can improve its power transfer efficiency. In addition, the circuit model of MC4C is verified by mathematical software and can describe the PTE and misalignment tolerance characteristics completely and accurately.

From experiment, the proposed MC4C structure achieve a PTE of 46% and 32% at a transmission distance of 40 mm and 50 mm, respectively. The degradation rate of MC4C is 41% under laterally misalignment of DL = 50 mm, which is less than that of the conventional four-coil configuration, 58%, implying a smaller performance degradation. For angular misalignment, the degradation rate of MC4C is merely 7% at an angular misaligned of 72 deg, which is much smaller than that of the conventional four-coil configuration, 32%. Therefore, it can verify that the proposed structure has a better misalignment tolerance.
