本文讨论了低功率高频无线电能传输系统的损耗分析。理想的WPTS效率评估模型可以预测出与真实性能相差较远的性能。该模型考虑了半导体器件的损耗以及二次侧整流的占空比和相位的调制。通过数值求解本文讨论的非线性方程组，确定了半导体器件和控制参数对整体WPTS性能的整体影响。在2 W@6.78 MHz的WPTS上实现的实验测量证明了该分析的有效性。
This paper discusses the losses analysis of low power high-frequency Wireless Power Transfer Systems (WPTSs). Ideal models for efficiency evaluation of WPTS can predict performances that are quite far from the real ones. The model proposed in this paper includes semiconductor devices losses, as well as modulation of duty-cycle and phase for the secondary side rectifier. The global influence of semiconductor devices and control parameters on the overall WPTS performances is numerically determined by solving the herein discussed non linear equations system. Experimental measurements realized on a 2 W@6.78 MHz WPTS demonstrate the validity of this analysis.
