NONCONTACT RECEIVING DEVICE, AND VEHICLE HAVING THE DEVICE

摘要

Provided is a noncontact receiving device comprising a load such as a charging unit (150) or a power supply object, and a secondary self-resonant coil (110) for receiving an electric power to be fed to the load from a primary self-resonant coil (240) disposed outside. The secondary self-resonant coil (110) is so constituted as can be switched between a first state, which is magnetically coupled to the primary self-resonant coil (240) by the resonance of a magnetic field and which is selected at a receiving time, and a second state, which is less magnetically coupled than the first state by the resonance of the primary self-resonant coil and which is selected at a non-receiving time.
