Title:
Radio electric power transmission equipment
Document Type and Number:
Japanese Patent JP6094820
Kind Code:
B2
Abstract:
A wireless electric power transmission apparatus as an embodiment of the present disclosure includes: two antennas 107, 109 having the ability to transmit electric power by a non-contact method via resonant magnetic coupling, one of the two antennas being a series resonant circuit, of which the resonant frequency is fs, the other antenna being a parallel resonant circuit, of which the resonant frequency is fp; and an oscillator 103 which is connected to one of the two antennas that transmits RF power. If the coupling coefficient between the two antennas 107 and 109 is k, then fs and fp are set so as to satisfy the inequality −1.1516×k2+0.0363×k+0.9983≰fs/fp<1.
