Communication Slots In A Wireless Power System

Abstract: This disclosure provides systems, methods and apparatuses for a managing timing of communication slots in a wireless power system. The communication slots are centered on zero-cross instances. The Power Transmitter and/or Power Receiver can use a phase locked loop (PLL) to determine the timing of the zero-cross instances. The wireless power system can determine when to begin a communication slot based on the timing of the zerocross instance and the slot width. For example, the beginning of the communication slot can begin at a time that is half the slot width before the time of the zero-cross instance.
