This Master's thesis work proposes an analytical study of the effects that misalignment causes in a wireless power transfer (WPT) system. WPT systems may become more practical charging solutions in the near future that will enable more frequent recharging, thus opening up the possibility of reducing the size of vehicle battery packs. Among the most important challenges to be faced, however, appear to be those of ensuring high transferable powers at efficiencies comparable to those of "wired" systems; in addition to the chosen geometry and electrical characteristics, misalignment is one of the factors that most degrades the performance of such systems: designing structures with high tolerance to misalignment and ensuring as much alignment as possible during energy transfer seem to be the two most important objectives in this regard.
