Abstract
The present application relates to an apparatus which comprises a wireless power transmission system. This system comprises features which allow it to transfer more power wirelessly to multiple devices simultaneously, each at extended distances than other systems operating in the same frequency range. The system including heat dissipation features, allowing the system 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 may include design features to withstand mechanical shocks, stresses, and impacts for use in a rugged environment. The system may include features to reduce electromagnetic interference (EMI) and/or 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.
