The system for synchronized time- ii- division wireless power transfer includes a wireless transmitter for generating and transmitting time-division wireless power transfer GC signals and a wirelessly powered device. The wirelessly powered device includes a wireless receiver for receiving the time-division 1-1 --.... wireless power transfer signals and a time division switching module. The time division switching module is coupled to the wireless Ir ---- receiver and generates multiple supply voltages synchronized to the time-division wireless power transfer signals for powering different 1-1 C circuitry of the wirelessly powered device.
