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

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel.

Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed. Sin ....etc

ABSTRACT:-
The coin-based mobile battery charger developed in this paper is providing a unique service to
the rural public where grid power is not available for partial/full daytime and a source of revenue for site
providers. The coin-based mobile battery charger can be quickly and easily installed outside any business
premises. The mobile phone market is a vast industry, and has spread into rural areas as a essential means of
communication.While the urban population use more sophisticated mobiles with good power batteries lasting
for sev ....etc
