Abstract
A wireless power system and method are provided that employ a hybrid approach to adjusting transmission power to take advantages of the best features of frequency mode adjusting and duty cycle mode adjusting. The wireless system and method attempt to modify duty cycle as a first adjustment, unless the duty cycle adjustment causes the duty cycle to be outside a predefined range. If the duty cycle adjustment causes the duty cycle to be outside a predefined range, the wireless system and method employ frequency mode adjusting to adjust transmission power.
