- Abstract
- In this paper, the efficiency of resonators for WPT using various litz wires is analyzed. By adjusting the value of distance between source coil and resonance coil (D_SR) and pitch of resonance coil (P_RC), the impedance bandwidth and efficiency of resonators can be optimized. It is observed that the thickness of wire forming resonator is the most critical parameter to determine the performance of a wireless power transfer system.
