Claim 0:
1. A power transmitter comprising:
a receiver circuit, wherein the receiver circuit is configured to receive at least one message(s) from;
an output circuit,
wherein the output circuit comprises a transmitter coil,
wherein the transmitter coils is configured to generate a power transfer signal,
wherein the power transfer signal is generated in response to a drive signal;

a driver circuit, wherein the driver circuit is configured to generate the drive signal;
a power loop controller circuit,
wherein the power loop controller circuit controls the drive signal so as to adjust a power level of the power transfer signal,
wherein the power control loop controller circuit is configured to apply changes to the power level of the power transfer signal in response to the at least one message(s);

a mode memory circuit,
wherein the mode memory circuit is configured to store a plurality of power level modes,
wherein each of the plurality of power level modes is associated with a reference power level;

a mode circuit,
wherein the mode circuit is configured to adapt the drive signal so as to set the power level of the power transfer signal to a first reference value in response to receiving a mode request message,
wherein the first reference value corresponds to a first reference power level of a first power level mode,
wherein the first power level mode is indicated in the mode request message,
wherein the first power level is one of the plurality of power level modes.
