Noncontact power feed system, noncontact relay apparatus, noncontract power reception apparatus, and noncontact power feed method

摘要

A noncontact power feed system includes: a noncontact power feed apparatus including a power feed resonance device to supply alternate-current power to an electronic apparatus by resonance in a noncontact manner, and an alternate-current power source section to generate the alternate-current power and supply it to the power feed resonance device; a noncontact relay apparatus including a relay resonance device to receive the alternate-current power and relay it to another electronic apparatus by resonance in a noncontact manner, a relay-side rectifier circuit to form direct-current power for output, and a movement means for moving the noncontact relay apparatus by the direct-current power; and at least one noncontact power reception apparatus including a power reception resonance device to receive the alternate-current power by magnetic field resonance in a noncontact manner, a power-reception-side rectifier circuit to form direct-current power for output, and a load means driven by the direct-current power.
