  Abstract

Wireless power transfer is a paradigm that reflects the need for an efficient charging system providing convenience. In this paper, we propose a DC-biased OFDM-based SWIPT(Simultaneous Wireless Information and Power Transfer) system. In the proposed system, wireless power transfer is performed through unmodulated high-power continuous wave, and information transfer is performed through small modulated signal. We designed receiver circuit for processing the SWIPT signal to minimize power consumption and circuit complexity. The receiver circuit serves to rectify and divide the received signal into power and information signal. We have fabricated the proposed receiver circuit and implemented for experiment of simultaneous transmission of information and power. Through the experiments, the performance of the proposed SWIPT system was verified.
