APPARATUS AND METHODS FOR SHIELDING A WIRELESS POWER TRANSMITTER |
| 摘要 |
Methods and apparatus are disclosed for wirelessly transmitting power. In one aspect, an apparatus for wireless transmitting power is provided. The apparatus comprises a first metal sheet having a shape that defines a plurality of slots, the plurality of slots inwardly extending from a periphery of the first metal sheet. The apparatus further comprises a coil configured to generate a magnetic field sufficient to charge or power a load, wherein the first metal sheet extends over a width and a length of the coil, and wherein the plurality of slots are configured to at least partially cancel eddy currents generated in the first metal sheet via the magnetic field. |
