発明の名称: (EN) NON CONTACT POWER SUPPLY SYSTEM AND POWER TRANSMISSION DEVICE
要約:
(EN) A non contact power supply system is provided with: a power transmission device (10c) that comprises a power transmission coil (14); and a power reception device (40) that comprises a power reception coil (41). Power is transmitted in a non contact manner from the power transmission coil (14) to the power reception coil (41) and power is supplied to a battery (44) that is mounted to the power reception device (40). The power reception device (40) comprises a first efficiency calculation unit (55) that calculates a first efficiency from a transmitted power command value and the power that is supplied to the battery (44). The power transmission device (10c) comprises: a second efficiency calculation unit (31) that calculates a second efficiency from the phase difference between the voltage and the current that are supplied to the power transmission coil (14); and a control amount calculation unit (29) that controls the power that is supplied to the power transmission coil (14) on the basis of the transmitted power command value and limits the power that is supplied to the power transmission coil (14) when the first efficiency becomes equal to or less than a preset first threshold efficiency or when the second efficiency becomes equal to or less than a preset second threshold efficiency.
