Title:
WIRELESS POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/125328
Kind Code:
A1
Abstract:
A wireless power transmission system transmits power without contact between a power transmitting resonator (105) and a power receiving resonator (107) which have different sizes through a resonant magnetic field having the resonance frequency (f0). A resistance value (Rs) per unit length at the frequency (f0) of the wiring forming an inductor (Ls) having the smaller size out of a power transmitting inductor and a power receiving inductor is set to be smaller in at least one section than a resistance value (RL) of the wiring forming the inductor (LL) having the larger size.
