Comparison of Two Basic Structures in Magnetically-Coupled Resonant Wireless Power Transfer
Wireless power transfer (WPT) has been a research focus in recent decades.Based on magnetically-coupled resonant wireless power transfer (MCR-WPT),this paper made a comparison of 2 basic structures in MCR-WPT,namely the 2-coil structure and the 4-coil structure.Their equivalent electric circuits were built.To illuminate the difference between these 2 structures,the input impedance,the transfer efficiency,and the load matching were studied and verified by experimental results.The conclusion can be drawn that without reducing the transfer efficiency,the additions of the source coil and the load coil in the 4-coil structure make it easier for the system to perfectly match the source and the load.
