Mobile Phone Charging by Using Witricity Technology with Charge Monitor

Abstract

Nowadays, requirement of continuous power utilization on daily basis is increasing. Users additional fascinated for technologies that can make their production convenience. Wireless mobile charger is a wireless energy transport that processes whereby electrical energy is transmitted from source to an electrical load as named battery, that does not have built-in power source or without the exploit of interconnecting wires or cables, this technology is called Witricity (Transformation of Electricity by means of Wireless ) electricity technology. This technique is one of the effective ways to transfer power wirelessly.The main aim of this study, i.e., wireless power transmission mobile charger circuit using inductive coupling is to charge the low power device by using wireless power transmission scheme. This aim is achieved by using charging a resonant electrical coil from AC followed by transmitting following power to the load. The work is meant to charge a low power apparatus or appliance (Mobile Phone) quickly and efficiently by inductive coupling without the need of wires.The transformation of energy from one form to another without using wire but through air medium is known as inductive charging. An inductive charging uses concept of inductive coupling known as mutual to transfer energy between the circuits by the electromagnetic field as its fundamental process.This paper helps in understanding the concepts and application of mutual Inductance in wireless charging.
