<p>This wireless power transmission device is provided with a pair of antennas capable of transmitting power through a resonant magnetic field coupling without contact therebetween, wherein one antenna in the pair is a series resonant circuit in which the resonant frequency is fs, while the other is a parallel resonant circuit in which the resonant frequency is fp. The wireless power transmission device is also provided with an oscillator connected to the antenna on the side transmitting high-frequency power, and a control unit for controlling the transmission frequency according to the amount of power transmitted between the antennas. fs/fp is set to be less than 1.</p> |
