Title:
WIRELESS POWER TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2019187237
Kind Code:
A
Abstract:
To provide a wireless power transmission system capable of enhancing power transmission efficiency from a transmission-side apparatus to a power incoming-side apparatus by controlling distribution of non-radiation electromagnetic fields from the transmission-side apparatus.SOLUTION: A wireless power transmission system 1 for wirelessly transmitting electric power from a transmission-side apparatus 2 to a power incoming-side apparatus 3 by using non-radiation electromagnetic fields, includes a dielectric substance or an inductor 4 of magnetic material which refracts non-radiation electromagnetic fields from the transmission-side apparatus 2, guides the electromagnetic fields toward the power incoming-side apparatus 3, thus controls distribution of the non-radiation electromagnetic fields.SELECTED DRAWING: Figure 1
