Abstract
Simultaneous wireless power and data transfer (SWPDT) technology is usually needed in wireless power transfer (WPT) systems. In this paper, to achieve the efficient and stable SWPDT, the signal to noise rate (SNR) is first optimized through the analysis of data transmission gain and the interference of power transfer on data transfer. In order to reduce the interference of power channel to data transfer channel, the compensation topology of double-sided LCC and the band-stop networks are used. To solve the problem of SNR limitation, the coupling relationships between each circuit are taken into consideration and a matching method of resonance parameters to improve the SNR is presented. Based on the relationship between SNR and the parameters of data transfer channel, an optimization design method focused on parameters of data transfer channel for improving the SNR is presented. Finally, the feasibility and the correctness of the parameter design method proposed in this paper is verified by simulation and experiment.

To increase the signal to noise rate (SNR) of simultaneous wireless power and data transfer (SWPDT) system, the increment of data transmission and decrement of power interference are considered by optimization of the data transfer channel
Summary
Flexibility, and high efficiency, wireless power transfer (WPT) technology is becoming more and more popular, and it has been applied in many fields, such as electric vehicles, mobile phones, wireless sensors, medical equipment, robotics [1,2,3,4], etc. Is carried out toout transfer data based based on the high-order harmonic of power flow to improve the data transmission rate. The power modulation toto some content, because it can avoid thethe using of data transfer coils modulationmethod methodisiscost costeffective effective some content, because it can avoid using of data transfer and modules. This method will inevitably lead to output power fluctuation. In reference [21],[21], the the data data transfer is achieved with the partial coil the while the data transmission is −10. In references transfer is achieved with the partial coil while data transmission gain is gain.
