With the rapid development of mobile appliances, wireless power transfer technique has been a hot issue for researchers. A resonant coupled power system called witricity with high efficiency and the middle range transfer distance is presented by MIT. The main circuit of the witricity system acts as a resonant converter operating in high frequency. The converter is a complex time variant and non-linear systems. So, it is difficult to obtain its accurate mathematical models. In this paper, the

With appropriate values for the circuit parameters, numerical results are compared with which in time domain model. The results show that theoretical analysis are well agree with the simulation, and by proposed method the computational time is remarkably reduced.
