A 6.78 MHz Multiple-Transmitter Wireless Power Transfer System with Integrated Coupling Coefficient Sensor
A 6.78 MHz multiple-transmitter wireless power transfer (WPT) system with integrated coupling coefficient magnetic and polarity sensor is proposed to achieve misalignment-free WPT. Compared to conventional systems, the perpendicular WPT efficiency increased 212x from 0.3% to 63.7%, with the load power increased from 0.3mW to 2W.
