Abstract
A wireless charging system having a power transmitting device may wirelessly transfer power to a power receiving device. The power receiving device may include a voltage regulator that operates independently from the power transmitting device. The voltage regulator may output a rectified voltage and may activate pull-down rectifier switches during zero voltage crossings to boost the rectified voltage. The power receiving device may send control error packets to the power transmitting device to direct the power transmitting device to adjust the transmit power level.
