1. A method for a receiving device to wirelessly receive electric power from a transmitting device, the method comprising the steps of:
- sending a first target level of a parameter associated with the electric power to the transmitting device;
receiving the electric power from the transmitting device; and
when the parameter of the received electric power reaches the first target level, sending a second target level of the parameter to the transmitting device, wherein the second target level of the parameter is determined based on a magnitude of a load coupled to the receiving device.

Abstract
Method and apparatus for wireless power transmission. A first target level of a parameter associated with the electric power is sent to the transmitting device. The electric power is then received from the transmitting device. When the parameter of the received electric power reaches the first target level, a second target level of the parameter is sent to the transmitting device. The second target level of the parameter is determined based on a magnitude of a load coupled to the receiving device.
