Abstract

Magnetic resonant coupling is one of the conditions for electromagnetic induction using a circuit topology. On the other hand, the relation between the main magnetic flux and the near magnetic field has not been sufficiently discussed in the discussion of the circuit topology, even though the main magnetic flux is used for energy transfer in wireless power transfer. The full explanation of the contribution of the main magnetic flux was not proposed with regard to a comparison between the magnetic resonant coupling and the other topologies. Therefore, in this paper, a series of explanations from the main magnetic flux to circuit topologies is presented, and the mechanism of magnetic resonant coupling is proposed with regard to circuit theory and electromagnetism. The proposed theory is validated through an electromagnetic field analysis and experiment.
