Critical Review and Simulation of Mid-range Wireless Power Transfer for Electronic Device

Functionality of wireless power transfer is yet to be utilized for the purpose of sustaining a green environment. This paper presents a critical review on the functionality of mid-range wireless power transfer using magnetic resonance coupling. Simulation of a 4-coils magnetic resonance for mid-range wireless power transfer is performed using CST microwave studio. The radius of source and load coil are 3 cm, while the radius of the transmitter and receiver coil are 5 cm. Distance between the source coil and load coil is set at 4 cm and resonance magnetic frequency is observed. At the load coil, electric field is achieved at 2140 V/m and surface current is recorded at 52.21 A. The change in impedance along the transmittance are plotted and discussed.
