Abstract

This brief proposes a Simultaneous Wireless Power and Data Transfer (SWPDT) method utilizing the third-harmonic component of a phase-shift modulated inverter for downlink communication. By dynamically adjusting the phase-shift angle, data is modulated via improved Differential Pulse Position Modulation (DPPM). A secondary-side harmonic isolation network is designed to suppres harmonic currents in the load. Theoretical analysis validates the load-independent nature of the transmission. Experimental results demonstrate a 310.45 W power transfer with 91.05% peak efficiency and a 36.3 kbps data rate.

基于改进DPPM的谐波同步无线供电和数据传输方法

本文提出了一种同时无线电源和数据传输（SWPDT）方法，利用相移调制逆变器的三谐波分量进行下行通信。通过动态调节相移角，通过改进的差分脉冲位置调制（DPPM）对数据进行调制。设计了一种二次侧谐波隔离网络来抑制负载中的谐波电流。理论分析验证了该传动的负载无关性。实验结果表明，传输功率为310.45 W，峰值效率为91.05%，数据速率为36.3 kbps。
