A multi-receiver WPT system with load-independent class-E/F inverter <Abstract> This paper proposes a load-indepedent high frequency wireless power transfer (WPT) system for multi receivers with single transmitter. The proposed system achieveszero-voltage switching (ZVS) at the transmitter and constantoutput voltage at all the receivers without specific controlagainst load variations. Therefore, the system requires no wirelesscommunication between receiver to transmitter and betweenreceivers. The design process of the proposed system is given.In the experiment, the demonstration for two receuivers system is conducted, achieving 83.4 efficiency% at 6.78 MHz and total output power of 50 W. |
