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, thedoi:10.11591/telkomnika.v12i5.4525 fatcat:hebmfejc3jaurnxjnsoy6tur3e
