  2. Introduction The 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.

  10. Description of HF transformers • Electric 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.
