NON-CONTACT POWER SUPPLY APPARATUS AND NON-CONTACT POWER SUPPLY SYSTEM
First Claim
1. A non-contact power supplying apparatus configured to supply a primary coil with AC power to transmit power in a non-contact manner from the primary coil to a secondary coil, the non-contact power supplying apparatus comprising:
- an AC power output unit capable of outputting AC power;
a power transmission unit including the primary coil;
a cable electrically connecting the AC power output unit and the power transmission unit;
a detector that detects a ratio of an output voltage and an output current output from the AC power output unit or a phase difference of the output voltage and the output current; and
a determination unit that determines whether or not an abnormality is occurring in the non-contact power supplying apparatus based on at least one of the ratio and the phase difference detected by the detector, wherein.each of the primary coil and the cable includes bundled conductive wires, andthe determination unit determines from the ratio and the phase difference whether or not at least one of the primary coil and the cable is partially broken and whether or not the primary coil is deformed.

Abstract
A non-contact power supply apparatus is configured to transmit power in a non-contact manner from a primary-side coil to a secondary-side coil by supplying alternating current power to the primary-side coil. The non-contact power supply apparatus is provided with an alternating current power output unit, a power transmitting unit, wiring, a detecting unit, and a determining unit. The alternating current power output unit is capable of outputting alternating current power. The power transmitting unit has the primary-side coil. The wiring electrically connects the alternating current power output unit and the power transmitting unit to each other. The detecting unit detects a ratio between an output voltage and an output current, which are outputted from the alternating current power output unit, or a phase difference between the output voltage and the output current. On the basis of the ratio and/or the phase difference detected by means of the detecting unit, the determining unit determines whether an abnormality has generated or not in the non-contact power supply apparatus.
