臺灣博碩士論文加值系統

本論文主要是分析與設計一組同時具有高效率以及高輸出功率的MHz頻率無線傳能(WPT)系統。為了要使系統高效率，傳送端的設計很重要，除了設計好E類功率放大器，此論文藉由匹配網路使系統負載壓縮在一定值實部範圍內使在寬負載範圍下維持高效率。
本論文完成一個含有傳送端(TX)、共振線圈(Resonator)以及接收端(RX)的無線傳能系統，其操作頻率為6.78MHz，其規格符合AirFuel聯盟所規範。傳送端的設計為E類功率放大器、線圈設計為共振電路以及接收端的設計為E類整流器，每一部分在本論文都會詳細的介紹與分析，最後整合整體系統電路完成無線傳能系統並且實作完成。此系統在實驗結果顯示在線圈耦合距離7公分其負載電阻為7Ω時，其效率最高可以達到82.5%且輸出功率為100W。且在不同負載範圍為4~25Ω其效率皆有75%，並且設計目標為可以應用在電動腳踏車的無線充電上面。

This paper mainly analyzes and designs a group of MHz frequency wireless power transmission (WPT) systems with high efficiency and high output power. In order to make the system high efficiency, the design of the transmitter is very important. In addition to designing a class E power amplifier, this paper uses a matching network to compress the system load within a certain real part range to maintain high efficiency under a wide-range load.
This paper completed a wireless energy transmission system that includes a transmitter (TX), a resonance coils (Resonator) and a receiver (RX). This operating frequency is 6.78MHz, and specifications are based on AirFuel Alliance specifications. The design of the transmitter is a class E power amplifier, the coil is designed a resonant circuit, and the design of the receiver is a class E rectifier. Each part will be introduced and analyzed in detail in this paper. Finally, the overall system circuit is integrated to complete the wireless power transmission system and the experiment is finish. The experiment results of this system show that when the coil coupling distance is 7 cm and the load resistance is 7 Ω, its efficiency can reach up to 82.5% and the output power is 100W. And the efficiency is 75% in different load ranges from 4 to 25Ω. The design goal is to be applied to the wireless charging of electric bicycles.
