Abstract
An apparatus includes a controller configured to control switches of a rectifier circuit, wherein the rectifier circuit is coupled to two terminals of a receiver coil configured to be magnetically coupled to a transmitter coil of a wireless power transfer system, and wherein in response to a high system gain of the wireless power transfer system, the controller configures the rectifier circuit as a half-bridge rectifier, and in response to a low system gain of the wireless power transfer system, the controller configures the rectifier circuit as a full-bridge rectifier.
