Along with the prosperous of magnetic coupled inductive power transfer( MCIPT) technology which is widely used in industrial applications such as electric vehicle charging,the topology of double D coils( DD coils) with a spatial quadrature Q coil arises with great research interest. The Q coil, however, has been thoroughly studied by adding to the receiving side but seldom to the transmitting side. By using finite element simulation, this paper presents a preliminary study on the effectiveness of Q coil in the transmitting side,and its inner dimension is optimized for optimal compensating the misalignment between the transmitting and receiver sides. Simulation results show that the windings of the Q coil should be placed in the center of the aperture of the DD coils,and these results render a useful guidance for mechanical structural design and circuit controller design of MCIPT. 相似文献
