Contactless power transfer system and method
DRIVE
September 28, 2011
A contactless power transfer system is proposed. The system includes a first coil (12) coupled to a power source (14) and configured to produce a magnetic field. A second coil (16) is configured to receive power from the first coil via the magnetic field. A field focusing element (18) is disposed between the first coil and the second coil and configured as a self resonant coil having a standing wave current distribution. The field focusing element is further configured to focus the magnetic field onto the second coil and enhance the coupling between the first coil and the second coil.
