Optimum design of coil for wireless energy transmission system based on resonant coupling

Coupler as an important component of the wireless power transfer system, its parameters properties are closely related to transmission efficiency of the wireless energy transmission system. This article discusses the optimum design of the coil, studies the impact of parameters of coil, including resistivity and number of turns, on the transmission efficiency in wireless energy transmission. Results from theoretical analyses and experiments indicate there is no relationship between the circle number of coil and the wireless energy transmission system transmission efficiency.
