To investigate the noise reduction of reactors driven by inverter power supplies, the method of the coupled magnetic and vibration analyses taking account of both electromagnetism and magnetostriction was developed, and the mechanism of noise generation was analyzed and verified by the measurement. Moreover, the methods of determining the optimal hardness of gaps and adding gaps in the yokes without changing the balance and reluctance of a three-phase reactor were also proposed. It was shown that the displacements of the improved reactor can be reduced to be 1/ 25 of the ordinary reactor in the 3-D analyses.

为了研究由逆变器电源驱动的反应器的降噪，开发了耦合磁和振动分析的方法，考虑了电磁和磁磁体，并开发了噪声，并通过测量进行了分析和验证噪声的机理。此外，还提出了确定间隙的最佳硬度和在不改变三相反应器的平衡和不情愿的方法中的最佳硬度和增加间隙的方法。结果表明，在3-D分析中，改进的反应器的位移可以降低为普通反应器的1/25。
