In this study, the power transfer principle and resonant topology selection method of the wireless power transfer system are explained. The magnetizing inductance and mutual inductance models, which are representative modeling methods for representing the magnetic coupling between the transmitting and receiving coils in wireless power transfer systems, are analyzed; additionally, the differences between the two modeling methods are explained. Furthermore, the active and reactive power of the wireless power transfer coils are analyzed in detail using the mutual inductance model; based on this, the differences between the transformer and the wireless power transfer coil system are described. In addition, through active and reactive power analysis, the phase difference between the transmitting and receiving sides required for maximizing power transmission is derived. Finally, the representative topologies of the wireless power transfer system are analyzed, and the required selection method for the optimal wireless power transfer resonant topology is described by considering the power transfer principle and the input and output characteristics of the wireless power transfer system.
