Title:
Radio electric power transmission systems
Document Type and Number:
Japanese Patent JP5934934
Kind Code:
B2
Abstract:
A wireless power transmission system is designed to transmit power between a power-transmitting resonator 105 and a power-receiving resonator 107, which are implemented as inductors LL and Ls of mutually different sizes, by a non-contact method over a resonant magnetic field with a resonant frequency f0 . When measured at the resonant frequency f0, the resistance value Rs per unit length of at least a part of wiring that forms the smaller inductor Ls is lower than that (RL) of wiring that forms the other larger inductor LL.
