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

LQG control of capacitive power transfer system
2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW), 2017This paper presents the design and simulation of an auto-tuning capacitive power transfer (CPT) system based on Class-E converter approach. The reason of selecting Class-E converter is due to the remarkably high efficiency that it can achieve. However, the load's variation affects the output voltage of Class-E converter significantly and increases the ...

Capacitive power transfer with impedance matching network
2016 IEEE 12th International Colloquium on Signal Processing & Its Applications (CSPA), 2016This paper presents the development of a new wireless power transfer technique using capacitive coupling. Capacitive power transfer (CPT) system has been introduced as an attractive alternative to the traditional inductive coupling method. This is due to the CPT benefits of simple topology, fewer components, better EMI performance and robustness to ...
