Wireless Battery Charger
In the future all electronic devices will be wirelessly powered. Small, battery-powered gadgets make powerful computing portable. The battery charger should be capable of charging the most common battery types found in portable devices today. In addition, the charging should be controlled from the base station and a bidirectional communication system between the pickups and base station should be developed. Inductive Power Systems: Inductive Power Transfer (IPT) refers to the concept of transferring electrical power between two isolated circuits across an air gap. While based on the work and concepts developed by pioneers such as Faraday and Ampere, it is only recently that IPT has been developed into working systems. Essentially, an IPT system can be divided into two parts; Primary and Secondary. The primary side of the system is made up of a resonant power supply and a coil. This power supply produces a high frequency sinusoidal current in the coil. The seconda
