Model no:174 The main objective of this project is to develop a system of wireless power transfer for medical applications. Many people use pace makers (An electronic device that works in place of a defective heart valve) implanted in their body that runs on a battery. The patient is required to be operated every year to replace the battery. This project is designed to charge a rechargeable battery wirelessly for the purpose.

This project is formed out of an AC 230V 50Hz to AC 20 KHz at 12V circuit. The output is fed to a tuned 20 KHz coil forming as primary of an air core transformer. The secondary coil develops a voltage of 20 KHz at 12volt while it is kept over the primary coil where air is used as the core. The output of the secondary is given to a high frequency bridge rectifier that delivers DC which is then regulated to maintain a constant charging current to a NiCd (Nickel Cadmium) rechargeable battery.

Normally these batteries have a long life of 7 years. Thus the patient’s operation time can be deferred to each 7 year after for replacement of the battery as the charging can be done for 7 years externally. But in the project a DC fan motor is provided in place of a battery charging arrangement for better visibility.
