Abstract

This paper presents a RIC-WPT system with class-E inverter and class-DE rectifier along with its analytical design procedure. By using the class-E inverter as a transmitter and the class-DE rectifier as a receiver, the designed WPT system can achieve a high power-delivery efficiency because of the class-E ZVS/ZDS conditions in both the inverter and the rectifier. In the experimental results, the system achieved 73.0 % overall efficiency at 9.87 W (50 Ω) output power, coil distance 10 cm, and 1 MHz operating frequency. The experimental results showed good agreement with the design specifications, which indicates the validity of the design procedure.
