Wireless power transfer

Abstract

Electric vehicles are making a new era in the world of vehicles and electronics where Bangladesh has just started getting the touch of this technology. It is very efficient and a way of saving our natural resources aiming to modernize these fuel free transports of Bangladesh. This paper is about a wireless charging system for EV and solar vehicles. The purpose of this project is designing and implementation of a system to enhance the performance of wireless power transfer system and to reduce the use of wires by using a Tesla coil as a transmitter to produce high frequency, high voltage with low alternating current in order to produce high density flux to transfer electric power. Power is transferred wirelessly by magnetic field which is created by direct induction followed by resonant magnetic induction which is a form of inductive coupling where the carried flux can be captured by inductive coil at the receiver that coupled to the primary coil. This tesla coil is involved to transfer power at a distance to a load or an electrical equipment that need to be charged or powered wirelessly. This system is developed so as to reduce the use of wire, save natural resources, on going power for electric vehicle and wireless charging. As a core factor, charging for solar vehicle is also mentioned.
