Title:
ELECTRIC POWER FEED DEVICE FOR VEHICLE AND ELECTRIC POWER RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/099106
Kind Code:
A1
Abstract:
Each of a plurality of electromagnetic induction coils (130) is configured to supply high-frequency electric power output from a high-frequency power supply device (110) to a resonance coil (150) by electromagnetic induction. The resonance coil (150) is an LC resonant coil, and it is configured to transmit electric power to a resonance coil (210) mounted on a vehicle (200) in a non-contact manner as a result of resonance with the resonance coil (210) through electromagnetic field. A switching device (140) is provided between the plurality of electromagnetic induction coils (130) and the high-frequency power supply device (110), and configured to be able to switch the electromagnetic induction coil (130) to electrically be connected to the high-frequency power supply device (110).
