Title:
NON-CONTACT POWER SUPPLY SYSTEM AND CONTROL METHOD FOR NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/076802
Kind Code:
A1
Abstract:
[Problem] To efficiently supply power in a non-contact manner using a relay device. [Solution] A non-contact power supply system (1) in which the transmission efficiency of a first route mode in which power is supplied from a power supply device (10) to a power receiving device (20) indirectly via a relay device (30) is compared with the transmission efficiency of a second route mode in which power is supplied directly without passing through the relay device (30), the route having a higher transmission efficiency is selected, and power is supplied. When using the first route mode, the power supply circuit (14) of the power supply device (10) is made to resonate with the power receiving circuit (31) of the relay device (30) and the power transmission circuit (32) of the relay device (30) is made to resonate with the power receiving circuit (31) of the power receiving device (20), but the power supply circuit (14) of the power supply device (10) and the power receiving circuit (21) of the power receiving device (20) are not allowed to resonate. When using the second route mode, the power supply circuit (14) of the power supply device (10) and the power receiving circuit (21) of the power receiving device (20) are made to resonate, but the power supply circuit (14) of the power supply device (10) and the power receiving circuit (31) of the relay device (30) are not allowed to resonate.
