Abstract
In this paper, we proposed an effective coil design for canceling the electromagnetic field noise from the wireless power transfer system by using shielding coil in transmitter and receiver for laptop computer application. EMF noise was significantly reduced with negligible change in induced voltage by using proposed coil with shielding coil near the coil. Difference between exiting coil and shielding coil is proven by simulation. And the guidelines to positioning of the shielding coil and the pros and cons of the shielding coil designs are discussed.
