要約(英語): Recently, research on wireless power transfer using a repeating coil has been increasing. We derived an output estimation equation with a basic equivalent circuit converted from a practical circuit with a repeating coil. Further, a novel simple equivalent circuit could be obtained by omitting the input resistance of the basic equivalent circuit. In this paper, the simple equivalent circuit is proposed. The output characteristic estimated by the simple equivalent circuit was almost the same as that estimated by the basic equivalent circuit. The characteristic calculated with the simple equivalent circuit was confirmed to be estimated well by measurements from multiple experiments. In addition, from the simple equivalent circuit, the estimation formula for the no-load output voltage could be derived. Furthermore, we investigated the effects on the estimation accuracy due to the omission of a parameter using an equivalent circuit. As a result, when ignoring the magnetic coupling of the nonadjacent coils, a clear difference in the estimation was confirmed. The cause was identified from a simple equivalent circuit.
