Abstract
Systems and methods for improved wireless recharging efficiency and decreased processing requirements are described. A plurality of duty cycle/input voltage pairs are stored in a recharger, corresponding to three subsets: a first subset corresponding to a constant minimum input voltage and an increasing duty cycle; a second subset corresponding to a constant duty cycle and an increasing input voltage; and a third subset corresponding to a maximum input voltage and an increasing duty cycle.
