Abstract:
Wireless Power Transfer (WPT) is a technology of transmitting electric, magnetic, optical, or microwave power without the use of physical connections. This technology is used to charge electric vehicles and other applications. It has several advantages over conductive charging method in terms of automation, safety in harsh environments, as well as reliability during environmental disasters. However, this technology faces challenges such as complex design, high cost, and sensitivity to misalignment and safety conditions for people. These challenges are associated with receiver and transmitter coils. This paper provides an overview of transmitter coil types, magnetic materials used, types of shields to provide safety for people, various pads structures, as well as the types of methods used to charge electric vehicles and electronic compensation circuits. This paper will be a reference for researchers and those interested in wireless power transfer to check these factors.
Keywords: Pads, Ferrite, Compensation Circuits, Shielding, Coupling Factor, WPT.
