Frequency is an important parameter that affects the efficiency of a wireless energy transmitting system. By derivation, an expression is presented which can indicate the relation among efficiency, capacitance and resonant frequency. Be aimed at a simulation model for a loosely coupled transformer, curves of the expression show detuning of the primary circuit will significantly affect system efficiency. Then a frequency tracking module is specially designed to add into a wireless energy transmission system to constitute an experimental platform. Experiments confirm that the frequency tracking module can help the system get higher efficiency which is measured to be 2.527%.
