摘要:	無線電力傳輸是一種具有潛力的技術，因具較高的便利性而漸漸受到重視。而本論文的目的是在無線電力傳輸的架構上加入訊號傳輸的功能。在無線電力傳輸的架構上傳送端跟接收端皆有一組LC諧振電路，並調整LC值使其諧振頻率相同。在傳送端以半橋式電路來驅使傳送端的線圈產生一交變磁通。依此架構實際所量測到的最大傳輸效率為53.34%輸出功率為2.22W。並在此無線電力傳輸架構上輸入以1KHz的方波模擬數位訊號，利用系統的主頻約109KHz為載波將訊號傳送到接收端，接收端可解調出1KHz的訊號。從實驗結果證實，在無線電力傳輸上做訊號傳輸是具有可行性。 The wireless power transfer technique is potential, due to a more convenience and getting attention. The purpose of this work is to add the signal transmission functions over the wireless power transfer. In the architecture of the wireless power transfer, both the transmitter and receiver side individually have an LC resonant circuit, which has been adjusted with the same LC resonant frequency. On the transmitter side a half-bridge circuit is used for driving coil to generate an alternating magnetic flux. In this design, the maximum efficiency of wireless transmission is about 53.34%, and the maximum output power is about 2.22W. With an input 1 KHz wireless square wave, over a carrier with frequency of about 109 KHz. To transfer the signal to the receiver, then the receiver can demodulate the 1 KHz signal. From the measurement results it demonstrated that the signal transmission over the wireless power transfer system is feasible.
