N2 - Inductive power transfer (IPT) offers a convenient and flexible charging way. Such superiority can be further enlarged by inserting intermediate coils and ferrite cores. In this paper, an IPT system with a reconfigurable intermediate circuit and ferrite cores is proposed. Two working modes, i.e., load-independent constant voltage (CV) and load-independent constant current (CC), can be realized. Zero voltage switching (ZVS) can also be achieved. By designing the entire system delicately, the magnetic coupler can significantly enhance the main magnetic couplings and reduce the unwanted cross-coupling phenomenon simultaneously. The fundamental analysis, coupler design, compensation topologies, and experimental validation results are all discussed in this article.
