Comparison Between Electromagnetic Induction and Magnetic Resonance Coupling

  • Takehiro ImuraEmail author


In this chapter, we compare the five circuits (N–N, N–S, S–N,S–S, S–P) and show the transition from the conventional method of electromagnetic induction. This way, we analyze the mechanism of magnetic resonance coupling, which sets the same resonance frequencies on the primary and secondary sides and can exert high efficiency and power under large air gaps and misalignment. Moreover, we discuss how magnetic resonance coupling corresponds to electromagnetic induction with narrower conditions to unify the understanding of electromagnetic induction and magnetic resonance coupling. We also discuss improvements in efficiency and power attributable to differences in circuit topology.
