SYNCHRONIZATION BASED ON FUNDAMENTAL HARMONIC RESONANCE

Abstract

Synchronization within a wireless power transmission system is used to ensure proper transfer of power. An example wireless power system includes a wireless power transmitter and a wireless power receiver, wherein the wireless power transmitter comprises a transmitter controller. The wireless power receiver comprises filter circuitry configured to receive an input signal from the wireless power transmitter, identify a harmonic signal of the input signal, and generate a filtered signal. The wireless power receiver also comprises converter circuitry configured to convert the filtered signal to an output signal, and a receiver controller configured to control the converter circuitry, wherein the receiver controller is synchronized with the transmitter controller based on the harmonic signal identified by the filter circuitry.
