Abstract: A wirelessly powered implantable medical device, a system for synchronized time-division wireless power transfer, and a method for closed-loop carrier waveform adaption for wireless power control are provided. The system for synchronized time-division wireless power transfer includes a wireless transmitter for generating and transmitting time-division wireless power transfer signals and a wirelessly powered device. The wirelessly powered device includes a wireless receiver for receiving the time-division wireless power transfer signals and a time division switching module. The time division switching module is coupled to the wireless receiver and generates multiple supply voltages synchronized to the time-division wireless power transfer signals for powering different circuitry of the wirelessly powered device.
