Using self-resonant coils in a strongly coupled regime, we experimentally demonstrated efficient nonradiative power transfer over distances up to 8 times the radius of the coils. We were able to transfer 60 watts with ∼40% efficiency over distances in excess of 2 meters. We present a ...

Theoretical analysis of wireless power transfer (WPT) via strongly coupled magnetic resonances (SCMR) is given on the coupled-mode theory (CMT) and circuit theory (CT). Furthermore, differences and similarities between these two theories are described. Some kinds of practical system structures are...

Strongly coupled four-coil wireless power transfer (WPT) system is presented in this letter. Conformal architecture is used for both transmitter (TX) and receiver (RX) coils. Thus, a high mutual coupling coefficient is achieved between the coplanar coils. Furthermore, the quality factors of prima...
For development of inductive coupled wireless power transfer (WPT) systems, it is important to consider the overall efficiency of the WPT systems, where the overall efficiency is expressed as the product of the transmission efficiency of coupling coils and the power-conversion efficiency of power con...

A novel analytical model of inductively coupled wireless power transfer is presented. For the first time, the effects of coil misalignment and geometry are addressed in a single mathematical expression. In the applications envisaged, such as radio frequency identification (RFID) and biomedical implants...
