Abstract

Wireless Power Transfer (WPT) is a field of science where energy can be transferred between two points (such as from a power source to an electrical load or consuming device) to charge electronic devices wirelessly. Examples of such electronic devices are cellphones, portable computers (laptops), integrated circuits, light emitting diodes, and electric vehicles. WPT can avoid the disadvantages of the traditional charging systems such as, power failure due short circuits, and dangerous battery materials. The advantages of WPT in comparison to the wired system include reducing the copper material, which is necessary to make cables, transmit power to isolated areas (deserts, mountains, and islands) where wired transmission is very difficult to implement, and the reduction of expenses. Wireless transmission is beneficial in cases where using cables or attached wires can be dangerous or unavailable. This research paper focuses on finding a valid distance range for Friis’ equation. MATLAB® program was used to calculate the predicted results for far-field WPT. By looking at the results, it is safe to conclude that the directed WPT is much more convenient in terms of transmitting covered distance and the Beam Efficiency compared to the isotropic WPT.
