Abstract

Along with the progress of the technology, people have an increasing demand of electricity. In the process of power transmission, the copper loss and wire aging will bring hidden trouble to the equipment. On special occasions, such as mining engineering and underwater working, the traditional power transmission system with wire will lead fatal harm to the workers. In this case, the technology of wireless power transmission has received more and more attention from all over the world. In this paper, an eight-figure coil is designed and analyzed to apply in wireless power transmission system. Compared with the circular coil and square coil, the eight-figure coil will generate relatively uniform magnetic field. When this coil is applied in wireless power transmission system, it will reduce the effect on the coil misalignment to the power transmission efficiency. Thus, it will broaden the application range of the wireless power transmission system.
