Patent ID: 10153664

Abstract:
A power transmitter includes: a first power transmission electrode having a flat surface; a second power transmission electrode that is spaced from the first power transmission electrode in a direction along the surface of the first power transmission electrode and has a flat surface; a power transmission circuit that is electrically connected to the first and second power transmission electrodes and outputs AC power to the first and second power transmission electrodes; a first conductive shield that is disposed between the first and second power transmission electrodes, the first conductive shield being spaced from each of the first and second power transmission electrodes; and at least one second conductive shield that is spaced from the first and second power transmission electrodes in a direction perpendicular to the surface of the first power transmission electrode and covers at least one of a first gap and a second gap, the first gap being disposed between the first power transmission electrode and the first shield, the second gap being disposed between the second power transmission electrode and the first shield.
