WIRELESS POWER TRANSFER

Submitted By

IntroductionThe main objective of this project is to develop a system of wireless power transfer for medical applications. Many people use pace makers implanted in their body that runs on a

battery.This project is designed to charge a rechargeable battery wirelessly . This project is formed out of an ac 230 volt 50 Hz to ac 20 KHz at 12 volt circuit. But in the project a DC fan motor is provided in place of a battery charging arrangement for better visibility.

Description of HF transformersElectric power transmission over long distances. High-voltage direct-current HVDC power transmission systems Large, specially constructed power transformers are used for electric arc furnaces used in steelmaking. Rotating transformers are designed so that one winding turns while the other remains stationary. A common use was the video head system as used in VHS and Beta video tape players. These can pass power or radio signals from a stationary mounting to a rotating mechanism, or radar antenna.
