Abstract

In this paper, a wireless power transfer system with semi-random magnetic flux is studied. Directions of semi-random magnetic flux are changing almost randomly which can induce voltages at coils irrelevantly to coil's posture. So, very convenient charging is possible. Semi-random magnetic flux can be generated by a coil system which has three coils perpendicular to each other and carrying currents with different frequencies. A prototype for charging mobile devices is constructed and tested, and the proposal is verified.
