DESIGN OF A WIRELESS CAPACITIVE POWER TRANSFER SYSTEM [PDF]
International Journal on Smart Sensing and Intelligent Systems, 2017 Abstract This paper presents the design of a capacitive power transfer (CPT) system by using the Class-E amplifier approach. The Class-E amplifier approach is chosen to be adopted since it produces high efficiency as close as to 100%, theoretically.
