Abstract This chapter covers different methods of wireless power transfer (WPT) with the main focus on weakly coupled inductive WPT systems. Such systems are increasingly getting popular due to the advantages they bring compared with wired power transfer. A typical two-coil inductive WPT system is analyzed, and the system parameters such as magnetic link efficiency are derived. Various WPT resonance topologies for both primary (transmitter) and secondary (receiver) coils are reviewed. Main elements of the system including high-frequency (MHz region) inverters such as class-D and class-E are explained. The WPT systems with multiple coils in primary, secondary, or in between them are covered. And the effects of coil size, shape, and alignment on the link efficiency are studied. The chapter concludes by exploring various coil components such as winding type, ferrite pad, and metal shielding plate for high-frequency and high-quality-factor coils.
