Abstract:
A system for providing power signals to peripheral devices on a vehicle using magnetic resonance coupling. The system includes a transmitter circuit having a variable current source, a base coil and a variable capacitor, where the current source and the capacitor are tuned to provide a predetermined AC current to the base coil so as to generate an oscillating magnetic field at a predetermined frequency. The system also includes a receiver circuit for each peripheral device, where each receiver circuit includes a receiver coil and a rechargeable power source. When the base coil is tuned to the receiver coil the power source can be recharged through magnetic resonance coupling to power the device. The transmitter circuit can be on the vehicle or can be separate from the vehicle, such as in a charging pad.
