NON-CONTACT POWER SUPPLY SYSTEM AND CONTROL METHOD FOR NON-CONTACT POWER SUPPLY SYSTEM
First Claim
1. A non-contact power supply system comprising a power supply apparatus, a power receiving apparatus, and a relay apparatus, whereintransmission efficiency in the case of performing non-contact power supply in a first route mode which is a mode of not performing direct non-contact power supply from the power supply apparatus to the power receiving apparatus but performing indirect non-contact power supply from the power supply apparatus to the power receiving apparatus through the relay apparatus, and transmission efficiency in the case of performing the non-contact power supply in a second route mode which is a mode of not performing the indirect non-contact power supply from the power supply apparatus to the power receiving apparatus through the relay apparatus but performing the direct non-contact power supply from the power supply apparatus to the power receiving apparatus are acquired, andthe mode of higher transmission efficiency is selected from the first route mode and the second route mode, and the non-contact power supply is performed from the power supply apparatus to the power receiving apparatus.

Abstract
A non-contact power supply system compares transmission efficiency between a case of a first route mode of indirectly supplying power from a power supply apparatus to a power receiving apparatus through a relay apparatus and a case of a second route mode of directly supplying power without interposing the relay apparatus, and selects a route of higher transmission efficiency to supply the power. In one potential route mode, a power supply circuit of the power supply apparatus and a power receiving circuit of the relay apparatus are made to resonate, and a power transmission circuit of the relay apparatus and a power receiving circuit of the power receiving apparatus are made to resonate, but the power supply circuit of the power supply apparatus and the power receiving circuit of the power receiving apparatus are not allowed to resonate.
