Abstract: The present application relates to an apparatus which comprises a wireless power transfer system. This system comprises features which allow it to transfer more power wirelessly at extended distances than other systems operating in the same frequency range. The system possesses heat dissipation features; these features allow it to operate effectively in elevated-temperature environments, and to transfer power at higher levels and/or greater distances than a typical power-transfer system. The system also might include design features to withstand mechanical shocks, stresses, and impacts for use in a rugged environment. The system can also comprise adaptations to reduce electromagnetic interference, and can comprise specially shaped components with magnetic/ferrimagnetic properties that enhance performance. Other potential features include power conditioning by combining, within one circuit or one board, multiple elements that protect against excessive current, over-voltage, and/or reverse voltage.
