Wireless charging a.k.a inductive charging, uses an electromagnetic field to transfer power and charge the device. It consists of having an inductive coil placed in the base of charging station and one in the device.
The operation method of wireless electricity transmission is done by magnetic induction technology. There are two coils, a transmitter coil and a receiver coil. An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiver coil. This voltage can be used to power a mobile device ..............etc

BATTERY CHARGERS & BATTERY BANKS
INTRODUCTION
NEED OF BATTERY CHARGERS & BATTERY BANKS
Station battery charger is used to supply the control power to the electrical switchgear like breakers etc which need the DC supply for it’s operation and in case of failure of electrical power the control power is continued to be fed by the battery.
Battery Charger consists of
1) Float Charger
2) Boost Charger
Schemes for Battery Chargers
1) FC & FCBC scheme
2) FCBC & FCBC scheme

Abstract “
A chip for inductive battery charging is presented, which needs no external components except an antenna to capture the energy from an electromagnetic field. The integrated system blocks are a front-end to limit and rectify the induced alternating voltage and a charge regulator with three control loops for the current, the vol..............etc

WIRELESS BATTERY CHARGING SYSTEM USING RADIO FREQUENCY ENERGY HARVESTING




INTRODUCTION AND MOTIVATION

Cellular telephone technology became commercially available in the 1980’s. Since then, it has been like a snowball rolling downhill, ever increasing in the number of users and the speed at which the technology advances. When the cellular phone was first implemented, it was enormous in size by today’s standards. This reason is two-fold; the battery had ..............etc

Abstract

It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use, you need an efficient way of charging the battery in the phone. But, like most people, you probably don’t like being tethered to the wall. Imagine a system where your cellular phone battery is always charged. No more worrying about forgetting to charge the battery. Sound Impossible?
It is the focus of this thesis to discuss the first step toward ..............etc
