Another embodiment provides a method for bi-directional non-contact power transfer including establishing communication between a first electrical device and a second electrical device of a bi-directional power transfer system, and determining one of the first electrical device and the second electrical device as a power transmitter and other of the first electrical device and the second electrical device as a power receiver. The method also includes converting input power of the power transmitter to an AC power, and providing the AC power to a transmitter coil of the power transmitter. The method further includes generating, using the transmitter coil, an oscillating magnetic field, and generating an alternating current in a receiver coil of the power receiver based on the oscillating magnetic field. The method also includes converting the alternating current to a direct current, and providing the direct current to a load of the power receiver.
Another embodiment provides a method for non-contact power transfer including establishing communication between a power transmitter device and a power receiver device, and negotiating power transfer requirements between the power transmitter device and the power receiver device. The method also includes providing a first alternating current to a transmitter coil of the power transmitter device, and generating, using the transmitter coil, an oscillating magnetic field. The method further includes generating a second alternating current in a receiver coil of the power receiver device based on the oscillating magnetic field, and converting the second alternating current to output power. The method also includes providing the output power to a load of the power receiver device.
