A Half-Duplex Simultaneous Wireless Power and Data Transfer System and Its Design Method Based on Amplitude Shift Keying
2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)(2023)
Abstract
This paper proposes a half-duplex simultaneous wireless power and data transfer (SWPDT) system and its design method based on amplitude shift keying (ASK). Since the setup of steady data carrier takes several periods of data carrier, the data rate is limited and delay is introduced. Therefore, in this paper the transient process of transferring bit ‘0’ and ‘1’ is analysed in detail and the relationship of system parameters with delay time and data rate and is given. Compared with previous research, the system design method takes communication delay and data rate into account. A 180W laboratory prototype was built to verify the correctness of the analysis.
