In applying inductive power transfer technology to a variety of devices, there are two issues to be resolved. The first is the limitation of the amount of transmission power due to the restriction on the strength of the magnetic field leakage. The magnetic field leakage has adverse effects on the surrounding environment, such as interference in wireless communications and inducing malfunctions in electronic devices. The second is that no general design method in arbitrary environments has been established for the transmitter and receiver coils although the design has a significant impact on power transfer efficiency and the magnetic field leakage. Up to now, a coil design is achieved through a trial-and-error process by adjusting parameters manually, therefore it is expensive to design coils for each device to be installed. In order to solve the above problems, this study first analyzes the two-dimensional current distribution using meshed conductors to maximize the efficiency while canceling the magnetic field leakage between transmitter and receiver coils, and then derives the coil shape from the current distribution based on the magnetic dipole moment. As a result of electromagnetic simulations, it is confirmed that the magnetic field leakage of the coils designed by the proposed method can be reduced by about 20 dB compared with that of the coils designed to maximize the efficiency without considering the magnetic field leakage. |
