- Abstract
In this study, the analysis of a three-coil wireless power transfer (WPT) system, which can be divided into source, communication and load circuits, is discussed in details. Among the three-coil WPT systems features, it is demonstrated, for instance, that maximum efficiency (ηMAX) and maximum power transferred to the load (P3MAX) do not depend on the load resistance, neither on the mutual inductance between communication and load coils. In fact, it is shown that ηMAX and P3MAX depend only on source and communication circuits parameters. Practical results are also presented, showing good agreement with the developed theory and validating the proposed analysis.
