- Abstract
- To achieve parallel power and data transmission in domino-resonator wireless power transfer (WPT) systems, a novel simultaneous power, and data transfer (SPDT) technology based on coil multiplexing is proposed in this letter. Benefiting from the magnetic field characteristics of the bipolar coil structure, the power and data can be injected into multiplexed coils with different flow directions, leading to opposite induced voltage polarities in each coupling coil. Subsequently, a corresponding resonator circuit is developed to form independent power and data resonance loops. In addition, an injected data transmission scheme is developed for domino-resonator WPT systems. Compared with traditional SPDT methods, additional wave trappers and coupling structures are avoided by this proposed technology, and the interference between power and data transfer is significantly eliminated. A 23.6 W laboratory prototype with five domino resonators is built to validate the feasibility of this proposed technology. The experimental results show that the power transfer efficiency reaches 70% at 50 kb/s data transfer rate. © 1986-2012 IEEE.
