| Abstract(in English) | The impedance expansion method (IEM), which was previously proposed by the authors, is a circuit-modeling technique for electrically-very-small devices. This report describes a circuit-modeling procedure for a wireless power transfer system by the IEM. First, the modal currents of the coil are obtained via eigenmode analysis, and it is shown that the behavior of the system can accurately be approximated only by the fundamental mode. Then, an equivalent-circuit model based only on the fundamental mode is proposed, and it is shown that the topology of the circuit model corresponds directly to the physical constitution of the system. |
