COUPLED RESONATOR TYPE RADIO POWER TRANSMISSION SYSTEM, AND POWER RECEPTION SIDE RESONATOR USED FOR COUPLED RESONATOR TYPE RADIO POWER TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a coupled resonator type radio power transmission system which is subject to little influence of a dielectric body between a power transmission side resonator and power reception side resonator and is capable of suppressing reduction in power transmission efficiency.SOLUTION: A coupled resonator type radio power transmission system having a configuration including a first coil 21 and second coil 22 arranged close to each other, and a capacitor 23 comprises: a power transmission side resonator 2 in which one of both ends of the first coil 21 and one of both ends of the second coil 22 are connected through the capacitor 23, and the other of both ends of the first coil 21 and the other of both ends of the second coil 22 are connected without using a capacitor, respectively; a controller 4 for controlling excitation of the power transmission side resonator 2; and a power reception side resonator which is arranged outside both coils 21 and 22 of the power transmission side resonator 2 and receives power transmitted from the power transmission side resonator 2.
