Abstract
Systems and methods for feedback control of output power in a wireless power transmitter are disclosed. According to one aspect, one of a voltage level at an input of a wireless power transmit coil and a level of current passing through the wireless power transmit coil are sensed. The wireless power transmitter includes a controller configured to adjust an electrical characteristic of the wireless power transmitter to maintain at least one of the level of current and the voltage level at a constant level.
