Abstract

Wireless power transmission (WPT) technology has been applied to many areas that driven by batteries. WPT system based on coupling coils is a popular method to realize WPT. In general, two coils are used in such system including a transmitting coil and a receiving coil. Two coils have to reach the same resonant frequency and impedance matching to assure high power transfer efficiency. In this paper, the influence of resonant frequency on transfer efficiency is studied. Inductance is closely related with frequency and capacitor. Hence, the influence of compensation capacitor on efficiency is also studied. Simulations have been done to perform the study. When the frequency is 130 kHz and the capacitance is 46.7 nF, the efficiency of the system reaches its maximum, and the efficiency of the system is 82.26%.
