An innovative extendible wireless power transfer system with load independent output voltage is developed in this paper. This system eliminates the interference caused by the cross coupling between nonadjacent coils and unrelated circuit networks among the receiving coils. The wireless power transfer system consists of a full-bridge converter power supply, transmitting resonator, relay resonators, and multiple receiving resonators. The theory of load independent output voltage is demonstrated in detail in this paper. The structure and features of the system has also been carefully illustrated. The simulation and experimental results show that the multiple receiving resonators do not affect each other when obtaining power and that the system can obtain load-independent output voltage. Experimental results and simulation analysis are highly consistent and the integrity of the theory is verified.
