Summary: This article presents an analysis and design of a high-efficiency, 6.78-MHz burst-mode controlled inductive wireless power transfer system without back-channel communication. The power flow between the transmitter and receiver is controlled through load modulation. By utilizing the inherent load modulation properties of the system, the need for traditional back-channel communication is eliminated. Experiments show that the quality factor of the transmitter can be detected to eliminate the back-channel communication. The proposed system only requires an additional switch in the receiver power stage to regulate the output voltage.

Summary: This article presents a wireless power transfer system that provides extended controllability of transmitting power for a wide range of link distances and load variations. The system uses a single-stage rectification and regulation process to deliver a stable 3-V dc voltage from a 13.56-MHz sinusoidal waveform. The transmitting power is controlled by the reflected impedance from the receiver to the transmitter, enabling high power transfer efficiency under different link distances and load variations. The proposed system also includes rising and falling edge detectors for low power and accurate zero current detection, as well as a digital voltage regulation controller for stable dc supply with fast response.
