PLANNING AND EXECUTION OF A MINIATURE WIRELESS POWER TRANSFER CHARGING SYSTEM

Abstract

Wireless power transmission has come a long way because to advancements in simulation speed and power electronics. Electric cars are seen as a potential alternative to vehicles powered by internal combustion engines that use oil in the transportation sector of the future. To achieve sustainable transportation, the idea of electric vehicles (EVs) has been put forth. Despite the fact that EV adoption is on the rise, addressing the challenges associated with batteries will need a technological breakthrough. One possible solution to the problems caused by EV batteries is the idea of Wireless Power Transfer (WPT) equipped EVs, which allow for the charging of EVs whether they are moving or at a standstill. Using inductive coupling as a framework, this research examines current technologies for wirelessly charging electric vehicles. Without physical connections, WPT transfers electrical power from a source to a load. When the car approaches the charging location, the WPT circuitry installed within it is triggered. The charging station supplies power to the main coil. The EV's main coil radiates flux, which is then induced by the secondary coil. The secondary coil's induced voltage is rectified and used to charge the electric vehicle's battery. This research demonstrates a method for efficiently charging a small electric vehicle model without the need of wires or other plug-in technologies. We successfully manage electromagnetic induction and establish efficient wireless power transfer, which allows us to charge our batteries effectively.
