APPARATUS FOR TRANSFERRING ELECTROMAGNETIC ENERGY

摘要

An apparatus for transferring electromagnetic energy comprising a coil arrangement operable to transmit a magnetic flux linkage to a receiver or to receive a magnetic flux linkage from a transmitter,wherein the coil arrangement includes a main coil and at least one auxiliary coil electrically combined with the main coil such that the combination of the main coil and the at least one auxiliary coil is arranged to alter an electromagnetic coupling between the coil arrangement and the transmitter or the receiver to increase an operation alignment range between the coil arrangement and the transmitter or the receiver.
