Efficient transmitters and receivers for high-power wireless powering systems

The efficiency of a wireless powering system is maximized when the power transmitter power-added efficiency (PAE), power receiver conversion efficiency (ηC) and wireless coupling efficiency (ηW) are maximized. This paper focuses on a general approach to the design of an efficient transmitter and receiver of a high-power wireless powering system, which is valid for any type of wireless power coupling. Experimental results for high-efficiency power transmitters and receivers at various frequencies and with various power levels are discussed.
