    Abstract: A large area wireless power system having a synchronization transmitter and a plurality of synchronization receivers for receiving a plurality of differential signals from the synchronization transmitter and outputting a plurality of second single-ended signals. The synchronization transmitter generates a first single-ended signal and converts the first single-ended signal into the plurality of differential signals to be transmitted to the synchronization receivers over a plurality of differential line pairs that also provide power to the synchronization receivers. The large area wireless power system also includes a plurality of high power amplifiers for receiving the plurality of second single-ended signals from the respective synchronization receivers and generating power, and a plurality of wireless power coils for receiving the power generated by the plurality of high power amplifiers and wirelessly providing power.
