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 ...
