An inductive wireless power system consists of a transmitter that generates a high frequency alternating magnetic field and a receiver that collects power from that field. The resonant coupled system described here provides for increased power transmit distance and reduced alignment sensitivity, with no need for a coupling core. To build a wireless power system four items are required: transmitter electronics, transmit coil, receive coil and receiver electronics. The LTC4120 wireless synchronous buck charger combined with minimal external circuitry comprises the receiver electronics.
