Wireless power transfer for small scale application

The password security wireless power transfer system is the integration of password security into wireless electrical power design which has a separate power design from source to load controlled by password controller. The revolution for wireless power and communications has arrived with wireless technologies widely integrated into wide range of products, provides new levels of convenience, interaction and monitoring. Consumer behaviours and demands have shifted for better reliability, convenience and innovative products. The research idea is innovative and no familiar design application and products are developed within designated electrical area. The research aims to design and develop a small scale wireless power transfer system via resonance inductive coupling wireless power technique to transmit power through high resonant frequency. A robust password security system is designed and developed using Arduino Deumilanove microcontroller, which adopts knowledge-based authentication technique to control the wireless power system. Full system analysis and experimental tests were conducted and it recorded 60% efficiency across transmitting distance of 50mm and the best transmitting and receiving antenna position are identified with range of 1 cm to 2 cm offset for antenna intersection for maximum efficiency. The research serves a good platform for electrical power design in security system and could be improvised further with advance system development, which can be commercialized to the public.
