Title:
ELECTRIC POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/079082
Kind Code:
A1
Abstract:
Provided is an electric power transmission device capable of effectively wirelessly transmitting power to an underwater vehicle in water. The electric power transmission device transmits power to an electric power receiving device having a power receiving coil in water and is provided with: one or more transmission coils including a power transmission coil for transmitting power to the power receiving coil through a magnetic field; an electric power transmission unit transmitting AC power to the power transmission coil; capacitors connected to the transmission coils and forming resonant circuits that are resonant together with the transmission coils; and a buoyant body connected to at least one of the transmission coils.
