Abstract
This application includes systems and techniques relating to wireless power transfer, such as a system including: sensing and measurement circuitry configured to process signals associated with a resonator and an impedance matching network coupled with the resonator; a PWM (pulse width modulation) generator configured to control a driving signal to drive the resonator through the impedance matching network; and a controller coupled with the sensing and measurement circuitry, the controller configured to adjust operation of the PWM generator and operation of the impedance matching network based on measured signals from the sensing and measurement circuitry.
