Abstract
A method includes in a switching cycle of a power converter in a wireless power transfer system, finding a time instant corresponding to one fourth of the switching cycle, wherein the power converter is coupled between an input power source and a transmitter coil magnetically coupled to a receiver coil, at the time instant, detecting a current flowing through the transmitter coil, wherein power transferred between the transmitter coil and the receiver coil is proportional to the current flowing through the transmitter coil, comparing the current flowing through the transmitter coil with a plurality of predetermined thresholds to determine whether a transient occurs, and applying a control mechanism to the power converter in response to an occurrence of the transient.
