臺灣博碩士論文加值系統

本論文建立於一般E類功率放大器的系統架構，配合微處理器(MCU)LPC1768在RLC匹配上面去偵測參數做出一個自動的匹配。傳統E類功率放大器要達到傳遞的最佳能量效率值，必須經過阻抗匹配、耦合線圈的分析與設計等複雜的計算還有不斷的驗證才能找出最合適的RLC匹配值。本研究中利用電感耦合式E類功率放大器來達到無線傳電的功能，再用微處理器中的類比數位轉換器(ADC)去偵測一次側與二次側的功率值，進行各個電容與已知電感的效率進行比對，找出一個最適當也是效率最佳的效率值。其次，在二次側的部分加入橋式整流電路，經由整流之後產生直流電，即可對此做出應用。

In this thesis, establishment of Class-E Power Amplifier structure, with MCU detecting parameters in order to finish automatic matching at RLC. To transfer the best power efficiency with traditional Class-E Power Amplifier, it has to go through impedance matching, analysis and design of coupling coil and other complicated calculation, at last, verifying constantly to find the most suitable RLC matching parameters. In the study, using inductive coupling Class-E Power Amplifier to wireless charging. MCU detects efficiency of primary and secondary side, comparison their efficiency with variety capacitance and known inductance and find the most suitable as well the best efficient of it. Finally, bridge rectifier was joined in the secondary side. By using it, it will generate DC power, and we can do some application with it.
