As　an　emerging　technology,　wireless　power　transfer　(WPT)　can　be　applied　in　many　fields　such　as　consumer　electronics.　Due　to　the　limited　charging　area,　the　user　experience　of　wireless　charging　for　consumer　electronics　needs　to　be　enhanced.　Based　on　the　tilted　long-track　transmitting　coil　array,　this　brief　proposes　a　high-degree-of-freedom　WPT　system　to　achieve　free　positioning　wireless　charging　when　the　receiver　is　placed　horizontally　or　with　a　tilted　angle　on　the　charging　plane.　Using　long-track　transmitting　coils　can　enlarge　the　charging　area　along　the　track　direction.　Using　the　transmitting　coil　array　and　supplying　power　via　two　adjacent　transmitting　coils　when　the　receiver　is　placed　in　between　the　transmitting　coils　can　enhance　the　charging　area　along　the　direction　perpendicular　to　the　track　direction.　Using　the　tilted　transmitting　coils　can　enable　wireless　charging　when　the　consumer　electronics　are　in　use,　normally　in　a　tilted　angle.　The　adopted　LCC-S　(inductor-capacitor-capacitor-series)　topology　facilitates　wireless　charging　with　a　weak　coupling.　The　proposed　system　can　achieve　free　positioning　wireless　charging　horizontally,　based　on　a　limited　number　of　transmitting　coils　and　no　selection　switches.　The　experimental　results　have　validated　the　proposed　WPT　system.　©　2004-2012　IEEE.
