中文摘要:
      利用πS-S补偿网络结合恒定互感耦合线圈实现无调压模块接收端的恒压输出. 首先,对πS-S补偿网络进行建模与分析. 其次,提出恒定互感耦合线圈的通用设计方法,实现接收端横向偏移下的互感恒定. 最后,通过样机实验,验证所提出设计方法的可行性与准确性. 实验样机的接收端直流输出电压波动小于3.6%,补偿网络与耦合线圈的传输效率达到95%,整机效率峰值达到82%.
英文摘要:
      A novel WPT system which contains πS-S compensation network and coupling coils with constant mutual inductance is proposed. The output voltage of receiver keeps constant without regular. It overcomes the drawbacks of present receiver with regular. Firstly,the πS-S compensation network is modeled and analyzed. Secondly,a design method of transmitting coil,which makes the mutual inductance constant,is also proposed. The mutual inductance of coupling coil keeps constant with the lateral movement of receiving coil. Finally,a WPT prototype with 1 megahertz is built to verify the deign method proposed. The output voltage drift of receiver is less than 3.6% with the variation of output power. The efficiency of coupling coils and its compensation network reaches 95%. The peak efficiency of prototype reaches 82%.
