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.

为了研究逆变电源驱动电抗器的降噪问题，提出了考虑电磁场和磁致伸缩效应的磁振耦合分析方法，分析了噪声产生的机理，并通过实测进行了验证。此外，还提出了在不改变三相电抗器平衡和磁阻的情况下，确定最佳间隙硬度和增加磁轭间隙的方法。三维分析表明，改进后的反应器的位移仅为普通反应器的1/ 25。
