Abstract: In this paper a revolutionary concept for handheld electronic devices is suggested for a wireless battery charger. The wireless power transmission is carried out by means of a magnetic coupling between a power transmitter that is connected to the grid and a power receiver that is built into the load unit. It presents an advanced receiver architecture which greatly improves the efficiency of power conversion. The solution proposed is norm compatible and appropriate for application of IC. SPICE simulations perform a distinction between a modern and the new receiver architectures. As shown by simulation tests, the proposed solution produces a power consumption gain of 40-45 per cent. A laboratory version of the planned wireless battery charger was performed and evaluated for system performance tests. As the experimental results reveal, due to the suggested design, the receiver performance lies within the 95.5 percent 99.5 percent range over the entire range of operating conditions
