摘要

One embodiment provides a non-contact power transmitter device including a sealed housing provided at least partially within a surface, and a transmitter coil within the sealed housing configured to inductively transfer power to a power receiver device. The power transmitter device also includes a transmitter control unit coupled to the transmitter coil, a transceiver configured to communicate with the power receiver device, and an electronic processor coupled to the transmitter control unit and the transceiver. The electronic processor is configured to establish, using the transceiver, communication with the power receiver device, and negotiate power transfer requirements between the power transmitter device and the power receiver device. The electronic processor is also configured to control the transmitter coil unit to transfer power to the power receiver device.

說明書

The first control unit 140 is controlled by the first electronic processor 120 to provide the alternating current to the first coil 145. The alternating current through the first coil 145 creates an oscillating magnetic field around the first coil 145. The oscillating magnetic field induces an alternating electromotive force that creates an alternating current in the second coil 175. The second electronic processor 150 controls the second control unit 170 to provide the alternating current from the second coil 175 to the second power conversion circuit 165. In one example, the second power conversion circuit 165 converts the AC power received from the second coil 175 into a DC power at a power output 185. For example, the second power conversion circuit 165 may include a rectifier to convert the AC power from the second coil 175 to a DC power output to a load. In some embodiments, when the load requires an AC power, the second power conversion circuit 165 may not be required or may be modified accordingly.
