WIRELESS POWER TRANSFER TRANSMITTER, SYSTEM AND METHOD OF WIRELESSLY TRANSFERRING POWER

An apparatus for use in a magnetic induction wireless power transfer system comprises at least one booster coil positioned adjacent an active coil of a magnetic induction wireless power transfer system and a capacitor electrically connected to the booster coil. A capacitance of the capacitor is selected such that a current in the booster coil is approximately equal to a current in the active coil during wireless power transfer. The apparatus may comprise at least one shielding coil positioned adjacent an active coil of a magnetic induction wireless power transfer system, a capacitor electrically connected to the shielding coil, and a conductor positioned adjacent the shielding coil opposite the active coil. The conductor encompasses the shielding coil.
