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.

为了研究变频电源驱动电抗器的噪声降低问题，提出了考虑电磁学和磁致伸缩的磁振动耦合分析方法，并通过测量分析和验证了噪声产生的机理。此外，还提出了在不改变三相电抗器平衡和磁阻的情况下确定间隙最佳硬度和在磁轭中添加间隙的方法。 3D分析表明，改进后的反应堆的位移可以减少到普通反应堆的1/ 25。
