発明の名称: (EN) WIRELESS POWER SUPPLY SYSTEM AND POWER TRANSMISSION DEVICE
要約:
(EN) A wireless power supply system includes a power transmission device (10c) having a power transmission coil (14) and a power receiving device (40) having a power receiving coil (41). The power transmission coil (14) transmits electric power to the power receiving coil (41) via a wireless connection, so as to supply the electric power to a battery (44) installed in the power receiving device (40). The power receiving device (40) includes a first efficiency calculator (55) configured to calculate a first efficiency based on a transmission power command value and the electric power supplied to the battery (44). The power transmission device (10c) includes a second efficiency calculator (31) configured to calculate a second efficiency based on a phase difference between a voltage and a current supplied to the power transmission coil (14). The power transmission device (10c) further includes a control amount calculator (29) configured to control electric power supplied to the power transmission coil (14) according to the transmission power command value, and regulate the electric power supplied to the power transmission coil (14) when the first efficiency falls to a predetermined first threshold efficiency or less or when the second efficiency falls to a predetermined second threshold efficiency or less.
