| Abstract(in English) | In recent years, Dynamic Wireless Power Transfer has been attracting attention as an application of wireless power transmission. There are several challenges in realizing wireless power transfer while driving, one of which is the effect of leaking magnetic fields. Since leaky magnetic fields have adverse effects on the human body and electronic equipment, they must be suppressed. Many suppression methods, such as cancellation coils and magnetic shielding, have been studied, but few studies have focused on the far-field leaky magnetic fields that are generated. In this paper, the far-field leakage magnetic field generated by wireless power transmission is estimated by vector potential. The validity of the estimation by vector potential is demonstrated by analyzing the intensity of the magnetic field generated 3 m to 20 m from the center of the coil when a cancellation coil for suppressing the magnetic field is installed in addition to the transmitting and receiving coils, and by comparing the results with the calculation results. Compared with the results of the analysis using the FEKO electromagnetic field analysis software, the vector potential estimation was confirmed to be accurate to within 1 % error. |
