The purpose of this paper is to propose a new control method of wireless power transfer system that can maintain stable power supply even when the positions of the primary and secondary coil or distance between the two coils largely change. The new method will be done by adjusting the switching frequency to a frequency that can obtain the desired output. We confirmed the effectiveness of new wireless power supply control method through experimental result which show that the maximum horizontal position deviation that can obtain a 20W output is 2.8 times longer.
