Coil Design for Magnetic Resonance Chargers

The pair of coupled coils constitutes the core of magnetic resonance chargers. Several geometries are possible for these elements. The geometry of the coils must be judiciously selected in the design process in order to meet requirements regarding sensitivity to misalignment, efficiency and leakage magnetic flux. This chapter reviews the usual geometries for coils in EV wireless chargers, including static and dynamic applications. It also describes the method to effectuate an adequate shielding.
