摘要: A system and method is provided for the inductive transfer of electric power between a substantially flat primary surface multitude secondary devices in such way that localized to vicinities individual device coils. The contact free does not require precise physical alignment can allow or be placed anywhere arbitrary orientation with respect surface. Such realized without need complex high frequency switching network turn coils on off completely scalable almost size. local anti-resonance architecture will block current from flowing when no are proximity RF network. presence tuned detunes surface; thereby enable transferred device. uniformity coupling active improved novel multi-pole driving technique which produces an apparent traveling wave pattern across
