This paper studies regular polygonal electromagnetic Halbach arrays used as transmitters in wireless power transfer systems. Four polygonal configurations are selected as typical research subjects. Through DC electromagnetic simulations in Ansys Electromagnetic Suite and experiments using practical circuits, this paper confirms the superiority of the proposed structures compared to conventional two-coil systems by generating an improved transmission power, which is 3 to 5 times higher than that of two-coil wireless power transfer systems, and a superior transmission efficiency, which is 5 to 10 times greater than that of two-coil systems, when the transmission distance exceeds 20 mm with a coil height of 50 mm. The average transmission power and efficiency at various z-coordinate positions and their standard deviations were obtained to compare the four selected structures. The ratio of the average transmission power (or efficiency) value to the standard deviations of each structure is analyzed quantitatively. The quantitative analysis reveals that, for polygonal EHA structures with uniform coil parameters, the pentagonal Electromagnetic Halbach Array emerges as the optimal structure in the four selected structures.
