Abstract

Aiming at the problem that the transmission efficiency and transmission power are difficult to achieve at the same time in the coupled resonant radio energy transmission process, based on the modeling and analysis of the equivalent structure of wireless power transmission S-S structure, this paper gives a method to synchronize transmission power and transmission efficiency under different loads and different distances, and further obtains that the optimal working frequency and the matching load resistance at a certain distance can make the power-efficiency synchronization reach the maximum value. By means of MATLAB simulation software, the experiment platform is set up to analyze the variation rule of system transmission efficiency and transmission power under different loads and different distances. The results demonstrate the correctness of the previous theory and provide a certain reference for improving the transmission efficiency and power of radio energy.
