NON-CONTACT POWER FEEDING SYSTEM, NON-CONTACT POWER FEEDING DEVICE, AND METHOD FOR TRANSMITTING NON-CONTACT POWER FEEDING BY NON-CONTACT POWER RECEIVING DEVICE

摘要

Of the plurality of transmitting antennas (11), power is supplied from the receiving antenna (211), the feeding unit (25), and the feeding unit (25), which can receive power from any transmitting antenna (11) in a non-contact manner, and an operation instruction is given. Upon receiving the signal, the power receiving device (2) having the start signal transmitter (211) for transmitting the start signal to the power transmission device (1,1a), the start signal receiver (1051) for receiving the start signal, and the start signal are transmitted. Upon reception, it has a power transmission unit (1042) that starts supplying power to a plurality of transmission antennas (11) and an antenna determination unit (1043) that determines a transmission target transmission antenna, and the power transmission unit (1042) is a transmission target. By supplying power to the transmitting antenna, the receiving antenna (211) of the power receiving device (2) is provided with a power transmission device (1,1a) for non-contact power supply.
