Abstract
System apparatus and method for providing wireless power transfer (WPT) from a WPT transmitter to a receiver. A switching arrangement is configured to have a first portion of the switching arrangement coupled to a first portion of the WPT transmitter, and a second portion being coupled to a second portion of the WPT transmitter. A controller may determine if a desired amount of power is being provided by an adaptive power supply, wherein the switching arrangement is configured to control the first and second portions of the switching arrangement to selectively operate the adaptive power supply between a single-ended mode and a differential mode to provide the desired amount of power with optimized efficiency.
