| 摘要 |
The present invention relates to a wireless power transmission system comprising a transmitter (100) and a receiver (200). The transmitter (100) comprises a transmission power unit (110), a transmission driving unit (120), a transmission control unit (130), a transmission terminal (140), and a transmission sensor unit (150). The receiver (200) comprises a receiving terminal (210), a receiving sensor unit (220), a receiving control unit (230), a receiving driving unit (240), and a load (250). The wireless power transmission system which has a power transmission efficiency sensing function applies an efficiency recognizing unit to the transmitter or the receiver. The efficiency recognizing unit comprises an efficiency sensing unit which senses the efficiency of power transmission and an efficiency output unit which informs the degree of the sensed efficiency in order for a user and a device to sense the degree of the sensed efficiency. [Reference numerals] (130) Transmission control unit; (140) Transmission terminal; (150) Transmission sensor unit; (163) Power transmission determination unit |
