Claim 13:
14. A method of transmitting wireless power from a base station comprising a power transmitter, the power transmitter including a control and communications unit and a coil configured to transmit a power signal, the method comprising:
providing, by the control and communications unit, power control signals to control a power level of the power signal configured for transmission to a power receiver;
providing, by the control and communications unit, a power request to an external power supply;
determining, by the control and communications unit, if the power signal at the coil is compliant with the power request;
storing a flag of non-compliance for the external power supply if the power signal is non-compliant with the power request;
determining if the flag of non-compliance was caused by a shutdown of the power transmitter or a brownout of the power transmitter when the flag of non-compliance is stored;
restarting the power transmitter when the flag of non-compliance was caused by a shutdown of the power transmitter, and repeat providing, by the control and communications unit, power control signals to control the power level of the power signal configured for transmission to the power receiver;
providing, by the control and communications unit, a reduced power request to the external power supply when the flag of non-compliance was caused by a brownout of the power transmitter;
determining, by the control and communications unit, if a reduced power signal at the coil is compliant with the reduced power request;
restarting the power transmitter when the reduced power signal at the coil is non-compliant with the reduced power request, and repeat providing, by the control and communications unit, power control signals to control the power level of the power signal configured for transmission to the power receiver; and
transmitting, by the coil, the power signal to the power receiver when the power signal is compliant with the power request or when the reduced power signal is compliant with the reduced power request.
