Abstract: A wireless power transfer circuit can include an input port that can be configured to couple to a power source, an ac excitation circuit having a port coupled to the input port, a resonant circuit coupled to the ac excitation circuit, and a controller circuit that can be configured to operate the ac excitation circuit. The wireless power transfer circuit can operate to inductively transfer power from the resonant circuit and the controller circuit can be configured to change an operating frequency of the ac excitation circuit and change a configuration of the resonant circuit responsive a change in indicated efficiency of the wireless power transfer.
