Abstract :
In this paper, a resonant coupling wireless power transmission system whose resonator using single-layer helical coils is designed. Based on analysis of equivalent circuit, the efficiency and optimal transmission distance are obtained, and its correctness is verified by experiment. The resonant frequency and electromagnetic field distribution of system are obtained through high frequency finite element simulation, and experimental result is consistent with the simulation. Based on experiments, the output load voltage related with different distance, driving frequency and displacement is analyzed.
