摘要：

A novel long distance multi-coil wireless power transfer (WPT) system with constant voltage (CV) output characteristic is designed and optimized in this paper. The CV output multi-coil WPT system mathematical model is systematically analyzed and summarized, and the system operating frequency can be calculating by this model. Through state deconstruction analysis, this paper has analyzed the distance between adjacent coils on the transmission efficiency of WPT system at a long distance. Finally, the experimental results are consistent with the theoretical analysis, and the maximum transmission efficiency is 54.2% under the transmission distance of 1.1 m.
