Power Efficient Simultaneous Wireless Information Transception and Power Reception Through an Isolation Barrier

IEEE Wireless Power Technology Conference and Expo (WPTCE), pp. 872–875

Abstract

We present a power efficient structure for simultaneous wireless information transception and power reception through an isolation barrier. The structure utilises a binary frequency shift keying (BFSK) communication scheme for efficient power and information reception and on-off-keying (OOK) harmonic backscattering for information transmission. The structure achieves an overall system efficiency above 55 % from 20 dBm to 26 dBm input power while receiving a BFSK signal with up to 40 MSym and backscattering a 100 kHz PWM signal.
