Coil Design for Wireless Power Transfer with Series-Parallel Compensation

The correct choice, calculation and design of the magnetic components of the system is a key factor of the high efficiency of the transmission of energy and reduce the mass-dimensional parameters of the coils. The paper is devoted to optimization of inductance coils for inductive power transfer. The paper compares and selects the shape of the coil and the core, and substantiates required for shielding. The influence of the design of the geometric parameters on magnetic and electrical characteristics of coils is investigated. On the basis of the conducted analysis, coils with and without a ferrite core are developed and simulated, a change in the parameters of the coils in case adding of ferrite coil are shown.
