Abstract: Methods and apparatus to clamp overvoltages for inductive power transfer systems are described herein. An example overvoltage protection circuit is described, including a first terminal configured to receive an alternating current signal for conversion to a second signal, a capacitor, a first switch configured to selectively electrically couple the capacitor to the first terminal based on an overvoltage detection signal to reduce an overvoltage on the second signal, and an overvoltage detector. The example overvoltage detector is configured to determine a signal level of the second signal and, in response to determining that the signal level of the second signal is greater than a threshold, to output the overvoltage detection signal to cause the switch to electrically couple the capacitor between the first terminal and a second terminal.

Abstract: Systems and methods of dynamic current limit are disclosed herein. A current is sensed a wireless charging circuit, for example. When the current sense reaches a reference current level while a communication is active, the current limit is enabled for the next packet. The current limit signal may be cleared for the next packet.
