The fundamental operation principles of magnetic resonance WPT will be given in this chapter, which starts with the introduction to WPT of two coupled inductors. Then it is proved that both the power transfer capability and the efficiency can be improved by properly compensating the coupled inductors. Later, the characteristics of a typical series-compensated primary and secondary (SS) WPT system are discussed in detail.
