Abstract
A wireless power supply with an adaptive control system that is capable of adjusting various operating characteristics and that avoids operating at those operating characteristics that present adverse affects, such as impaired communications or interference with operation of the remote device. In one embodiment, the control system is capable of adjusting two or more of the operating frequency, duty cycle, rail voltage and switching circuit phase. In one embodiment, the wireless power supply control system is configured to detect operating characteristics that present adverse affects, maintain a record of those operating characteristics and avoid those operating characteristics once detected. In another embodiment, the remote device may be configured to advise the wireless power supply control system of certain “keep-out” ranges that adversely affect operation of the remote device.
