Design of auto-tuning capacitive power transfer system for wireless power transfer
International Journal of Electronics, 2015ABSTRACTThis paper presents the design of capacitive wireless power transfer systems based on a Class-E inverter approach. The main reason for adopting the Class-E inverter approach is because of its high efficiency, theoretically 100%. However, the operation of a Class-E inverter is highly sensitive to its circuit’s parameters. In a typical capacitive
