Classification: CPC H | IPC H

Claim 11:
12. The method of claim 11, further comprising:
setting, by the wireless charging transmitter, the full bridge inverter of the wireless charging transmitter to the full bridge inverter mode;
reducing, by the wireless charging transmitter, the transmit power of the wireless charging transmitter until the induced rectifier voltage of the wireless charging receiver meets the target rectifier voltage; and
saving, by the wireless charging transmitter, the operating point of the wireless charging transmitter as a lower induced voltage operating point associated with the full bridge inverter mode, the lower induced voltage operating point being selected to dampen a-change in the induced rectifier voltage of the wireless charging receiver when switching the full bridge inverter to the full bridge inverter mode; and
dampening the change in the induced rectifier voltage of the wireless charging receiver while switching the full bridge inverter from the half bridge inverter mode to the full bridge inverter mode by setting the operating point of the wireless charging transmitter to the lower induced voltage operating point.
