本論文主要是對無線傳能系統中的傳送端電路進行研究與實現。主要應用於符合A4WP規範的13.56 MHz頻率下之磁共振無線充電系統,此傳送電路為可提供高功率與高效率的E類功率放大器。
首先論文第一章對無線傳能系統之分類與應用做簡單之介紹;第二章針對現在常用的幾種功率放大器各別的原理與差異做介紹;第三章則著重在功率放大器中的E類功率放大器進行細部的分析與探討,藉由理論與數學推導得到各參數的公式,方便未來進行設計使用;第四章為利用PCB四層板技術,製作一個可應用於13.56 MHz頻率下之磁共振無線充電系統傳送端功率放大器,其直流供應電壓為24V,且在最佳負載下有90%以上的效率和5W以上的輸出功率;第五章則利用此E類功率放大器對一般四級共振線圈和自製的3D四級共振線圈進行能量的傳輸,藉由觀察系統使用上之變化,對系統進行分析;第六章則是為了提升無線傳能系統效率,利用台積電的25 um互補式金氧半場效電晶體製程搭配外掛其負載網路的被動元件來設計一個一樣應用於13.56 MHz頻率下之磁共振無線充電系統,但可根據變動負載進行調控切換式的E類功率放大器;最後第七章為結論與未來展望。


This thesis goal is to design the transceiver in wireless power transfer system (WPTs). Transceiver mainly use 13.56 MHz high-power and high-efficiency Class E power amplifiers, which conform A4WP magnetic resonance WPTs standard.
First, chapter one is about the simple introduction and the application of WPTs. In chapter two, we will simple present some differences in several types of power amplifier which we commonly used. In chapter three, we focused on the analysis and the discussion in details. By using the theoretical and the mathematical derivation, we can get the formula of each parameter to design the class E power amplifier. In chapter four, a class E power amplifier is presented for 13.56 MHz WPTs applications by using four-layer board PCB technology. The voltage of the DC power is 24V and the measurements of the best efficiency and the best output power have to be more than 90% and 5W. In chapter five, we used this experimental board as transceiver in WPTs, which is operated on general four stages magnetic resonance coil system and 3D four stages magnetic resonance coil system. By measuring and observing the experimental results in the system, we can analyze the results and improve it. In chapter six, in order to improve the efficiency in WPTs, a class E power amplifier is presented for 13.56 MHz WPTs applications by using TSMC 25um CMOS process and off chip passive components. The class E power amplifiers can be regulated by varying the load in WPTs. Finally, the conclusion is given in chapter seven.
