Abstract:
A method for operating a wireless charging transmitter includes switching, by the wireless charging transmitter, an operating mode of a full bridge inverter of the wireless charging transmitter from a first mode to a second mode; and changing, by the wireless charging transmitter, an operating point of the wireless charging transmitter from a first operating point associated with the first mode to a second operating point associated with the second mode, the second operating point being selected to dampen a change in a rectifier voltage of a wireless charging receiver inductively coupled to the wireless charging transmitter.
