| Summary: | 碩士 === 國立中央大學 === 通訊工程學系在職專班 === 101 === 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.
