Design of a Wireless Power Transmission System With Magnetically Integrated Compensation Network

Abstract

Inductive power transfer (IPT) technology has the advantages of convenience and safety. The complete, reliable and excellent performance has been a hot research topic worldwide. Magnetic integration technology refers to the winding of two or more discrete magnetic elements in the same core to form a complete magnet. The magnetic integration is a promising process which integrates the magnetic elements in a single structure, allows the magnet loss, volume and net weight on a pair of cores to be reduced, thus increasing the portability and circuit performance. In this paper, we propose an IPT system with magnetic integration. Its double D round structure coils enable the absence of the compensation network at the receiver side and has an advantage on improving the misalignment performance on IPT system, meanwhile effectively reduces the weight and volume of the system, making miniaturization of the system possible and maintaining the power transmission capability.
