Abstract
Techniques for improving efficiency of wireless power transfer to shunt-based receiver are provided. In an example, techniques can optimize wireless power transfer by comparing instantaneous peak voltage of a transmit coil of a wireless power transmitter to an average peak voltage of the transmit coil, and then, based on the comparison, adjust a setpoint of the wireless power transmitter to a more efficient level.
