Wireless power transfer system with a simple receiver coil

This paper proposes a wireless power transfer system that consists of a transmitter with a resonator and a receiver without a resonator. This system utilizes magnetic coupling and resonance. The receiver is simple, but this system has longer transfer distance than electromagnetic induction and requires no resonant frequency synchronization between the transmitter and the receiver that is required for magnetic resonance method. In general, receivers have main function other than power receiving function and it is favorable that receivers have less restriction for placement and simple adjustment mechanism. The proposed system offers solutions for these issues.
