ppt presentation of wireless battery charger using microwaves rf to dc conversion

Battery life of mobile phone is always been a problem for manufacturers. People are complaining about their mobile s battery life, that they don t have long battery life and they have to charge their phone several times. Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing, the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It i ....etc

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

The battery is charged with small amount of AC voltage or DC voltage. So if you want to charge your battery with AC source then should follow these steps, we need first limit the large AC voltage, need to filter the AC voltage to remove the noise, regulate and get the constant voltage and then give the resulting voltage to the battery for charging. Once charging is completed the circuit should automatically turned off.

The AC source is given to the step down transformer which converts the large AC source into limited AC source, filter the AC ....etc

LEAD-ACID BATTERY CHARGER WITH
VOLTAGE ANALYSER
INTRODUCTION
Nowadays maintenance-free lead-acid batteries are common in vehicles, inverters, and UPS systems. If the battery is left in a poor state of charge, its useful life is shortened. It also reduces the capacity and rechargeability of the battery. For older types of batteries, a hygrometer can be used to check the specific gravity of the acid, which, in turn, indicates the charge condition of the battery. Howev ....etc
