POWER TRANSMITTING DEVICE, POWER RECEIVING DEVICE, NON-CONTACT POWER TRANSMISSION SYSTEM, AND METHOD FOR CONTROLLING TRANSMISSION POWER IN NON-CONTACT POWER TRANSMISSION SYSTEM |
摘要 |
<p>A non-contact power transmission system (1) comprises a power transmitting device (4) and a power receiving device (7). The power transmitting device (4) transmits AC power modulated on a carrier to the power receiving device (7). The power receiving device (7) changes the resonance frequency of a power receiving antenna (20) by changing the load of the power receiving device (7) to control the reception of the AC power. The power transmitting device (4) detects, in response to the change in the load of the power receiving device (7), a modulated signal that is superimposed on the carrier of the AC power, and controls the transmission of the AC power on the basis of the detected modulated signal.</p> |
