Abstract
A power transmission device is configured to transmit power underwater to an underwater vehicle having a power reception coil. The power transmission device includes a power transmission coil configured to transmit power to the power reception coil through a magnetic field, a power transmission unit configured to transmit an alternating current voltage having a frequency a 10 kHz or lower to the power transmission coil, and a first capacitor connected to the power transmission coil and configured to form a resonance circuit resonating at the frequency with the power transmission coil.
