NONCONTACT POWER SUPPLY APPARATUS AND NONCONTACT POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a noncontact power supply apparatus capable of supplying power to a power supply target without precise positioning between a power supply coil and a power reception coil and supplying and ensuring the power supply from the noncontact power supply apparatus to a power supply target even when alignment between the power supply coil and the power reception coil is poor.SOLUTION: The noncontact power supply apparatus includes: plural power supply coils 23 disposed along an opposite plane 22; a power source unit 25 that selectively supplies a high-frequency voltage to the power supply coil 23; a coil selection unit 42 that selects one or plural power supply coils 23 disposed at a position opposing to the power reception coils 33 at least a part of which is disposed on the opposite plane 22 as the target coil of excitation; and a coil control section 42 that controls the power source unit 25 to supply a high-frequency voltage to the power supply coil 23 selected by the coil selection unit 42 as the target coil of excitation.
