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效果，提出了同时考虑电磁和磁致伸缩的磁振耦合分析方法，分析了电抗器噪声产生的机理，并通过测量对其进行了验证。此外，还提出了在不改变三相反应器平衡和磁阻的情况下确定最佳间隙硬度和在线圈中增加间隙的方法。结果表明，在三维分析中，改进后的反应器的位移可以减少到普通反应器的1/25。
