摘要：
The wireless power transfer efficiency of tunable load impedance is addressed in this paper. The load impedance is a key factor to dominant the whole system efficiency. This paper addresses individual efficiency of the transmitter, receiver, resonant coils by the variation of load impedance. Afterward, the integration of transmitter, receiver, resonant coils to achieve a power trasfer system. Measurement demostrates the total efficiency is 60% at the enviroment of load impedance of 10 Omega and coupling distance of 5cm.
