EMI Reduction Method in Wireless Power Transfer System with Increasing Efficiency using Frequency Split Phenomena
This paper describes a method to reduce magnetic field leakage from a Wireless Power Transfer (WPT) systems. By using frequency split phenomena, the reactive shield can reduce the magnetic field of the target frequency band with increasing power transfer efficiency. The simulation results of the suggested reactive shielding coil structure are verified with a 50W-WPT system.
