Title: Design of high-efficiency inductive-coupled wireless power transfer system with class-DE transmitter and class-E rectifier
Abstract: This paper proposes an inductive coupled wireless power transfer (WPT) system with class-DE transmitter and class-E rectifier along with numerical design procedure. The proposed WPT system can achieve high power-transfer efficiency at high-frequencies because both the transmitter and the rectifier satisfy the class-E ZVS/ZDS conditions. By using numerical design procedure, it is possible to design the WPT system without analysis of the circuit and consideration of the impedance matching. By carrying out the circuit experiment, the validity of the design procedure and effectiveness of the proposed WPT system were confirmed. The laboratory measurement showed the 90.4 % overall power-transfer efficiency with 100 W output at 500 kHz operating frequency.
