Wireless Battery Charger (RF/Microwave to DC Conversion)
Because of technological advancements in electronics it is now possible to charge the portable devices batteries using wireless power transfer technology. This paper deals with wireless battery charging, its current limitations and exploration on communication possibilities to conserve power. Also, efficiency improvement of wireless power transfer was accomplished with modified receiver architecture. Wireless power transfer contains transmitter and receiver, the hand held will have the power receiver circuit which charges the battery and communicate the status back to vary the power intensity or charge status.
