提出了降低电动汽车感应功率传输系统辐射噪声的方法。在电动汽车IPT系统中，由于IPT系统的辐射噪声必须被抑制才能满足标准，因此需要采用降噪技术。通过改变逆变器的输出频率，传输线圈的辐射噪声在频域内传播。实验结果表明，与恒频系统相比，该方法对基频附近的谐波分量抑制了33.1%。
Reduction methods in radiation noise of inductive power transfer (IPT) systems for electrical vehicles (EVs) are proposed. In the IPT system for EVs, noise reduction technologies are required because radiation noise from the IPT system have to be suppressed to satisfy the standards. By changing the output frequency of the inverter, the radiation noise from the transmission coils is spread in a frequency domain. From the experimental results, the harmonics components around fundamental frequency are suppressed by 33.1% by using the proposed method in comparison with the system using a constant frequency.
