When three-coil structures is mor efficient for wireless power transfer

What is it about?

In this paper, the condition for a three-coil structure obtaining higher energy efficiency over its two-coil counterpart is derived, Additionally, it also shows that the three-coil system has the significant advantage of reducing the current stress and the electromagnetic field emission that is caused by misalignments.

Why is it important?

This paper provides very intuitive analysis for understanding the three-coil structure of wireless power transfer system. And the electromagnetic field (EMF) effects when the coils are misaligned is discussed
