Three-phase electric power (three-phase) is an essential technology for high power electric wiring. Three-phase, however, has not been attached to wireless power transfer (WPT). The authors suggest that characteristics of three-phase system are suitable for high power WPT with magnetic resonant coupling. Three-phase WPT has three times as large capacity as conventional single-phase WPT has. The power...
Wireless power transfer via magnetic couple resonance has been widely studied as an attractive research target. In order to improve the transmitting efficiency, not only increasing performance of antenna is important but also controlling secondary (receiver) side input impedance value. As a method of controlling secondary input impedance, the method of using a DC-DC converter is proposed in previous...
