The method 400 also includes negotiating power transfer requirements between the power transmitter device 310 and the power receiver device 315 (at block 420). The transmitter electronic processor 320 and the receiver electronic processor 345 negotiate over the wireless connection established between the power transmitter device 310 and the power receiver device 315. The transmitter electronic processor 320 and the receiver electronic processor 345 negotiate to determine the power requirement, for example, the voltage, frequency, and the like for the non-contact power transfer. In one embodiment, the receiver electronic processor 345 communicates the power requirements of the power receiver device 315 to the transmitter electronic processor 320 and the transmitter electronic processor 320 controls the transmitter control unit 335 accordingly.
The method 400 also includes providing, using the transmitter control unit 335, alternating current to the transmitter coil 340 (at block 430). For example, as described above, the transmitter control unit 335 provides alternating current from the power input 375 to the transmitter coil 340. The method 400 further includes generating, using the transmitter coil 340, an oscillating magnetic field (at block 440). The alternating current flowing through the transmitter coil 340 generates an oscillating magnetic field. The method 400 also includes generating an alternating current in the receiver coil 370 (at block 450). The oscillating magnetic field induces an electromotive force that creates the alternating current in the receiver coil 370.
