相對於市面上的無線充電產品，很少人提出穿越金屬屏障的相關論文，目前為磁感應無線充電產品及技術較廣為使用，經過金屬屏障時，強大的渦流損將伴隨著高溫，對使用產品安全產生影響，效率也跟著降低。
本文提出一種能穿越金屬屏障的概念，首先介紹各種無線傳輸技術，並進一步介紹磁感應傳輸技術中的磁場分析，穿越金屬屏障的原理與方法。為了驗證此方法與實驗之可行性，先設計市面上常見的金屬隔板縫隙，並對無線充電系統中發射線圈與接收線圈進行設計與模擬，再由模擬結果設計磁性元件，用來集中磁場，並對各種串並聯補償架構及不同種控制方法進行評估與選用。最後選用串聯-串聯補償電容，及使用變頻控制，進行五階交流電路之電壓增益推導與模擬，並實作一台400瓦CLLC之諧振式無線充電系統來驗證所提方法。由實驗結果顯示，當未隔金屬隔板時，輕載效率為82.40%，滿載效率為89.55%。添加金屬隔板時，輕載效率為68.45%，滿載時系統效率為84.68%。

Few wireless charging products on the market can transfer energy through metal barriers. The main reason is that most products currently use magnetic induction wireless charging technology. When passing through metal barriers, strong eddy current loss will be accompanied by high temperature, which will affect the safety of products and the efficiency will also be decreased.
This thesis proposes a concept charger that can transfer energy through the metal barrier. This study firstly introduces various wireless transmission technologies and further introduces the magnetic field analysis in the magnetic induction transmission technology, and the principle and method of passing through the metal barrier. To verify the feasibility of this method, the common metal partition gaps on the market were first designed, and the transmitter coil and receiver coil in the wireless charging system was designed and simulated, and then the magnetic cores were designed based on the simulation results to concentrate the magnetic field. This study also evaluates and selects various series-parallel compensation architectures and different control methods. Finally, series- series compensation capacitors are used, and frequency control is used to acquire the voltage gain of the fifth-order AC circuit. A 400-watt CLLC resonant wireless charging system is also implemented to verify the proposed method. The experimental results show that when the metal separator is not added, the light load efficiency is 82.40%, and the full load efficiency is 89.55%. When the metal separator is added, the light load efficiency is 68.45%, and the system efficiency at full load is 84.68%.
