摘要
Abstract
In recent years,the wireless power transmission via magnetic resonant coupling has been extensively researched for various applications.In the process of wireless power transmission,the change of distance leads to a significant reduction in the power transmission efficiency.To solve this problem,a new impedance matching method inverting the impedance of receiving port as equivalent impedance of the load port is proposed,which makes the system power transmission efficiency fluctuation reduced when both the position and the load changes,so as to achieve the efficient transformation of the high-frequency signal from the transmitter to the receiving end and reduce the signal reflection.Through ADS software simulation verification,this method can improve the system transmission efficiency in case of small changes in the transmission distance.关键词
