The test results show that the transformer wound with this magnetic core will not enter the saturation zone when the magnetic bias continues to increase,which avoids deep saturation of the transformer and inverter failure,enhances the transformer’s ability to resist magnetic bias,greatly improvesthe reliability of the inverter welding machine and eliminates the arc whistling. 纳米晶磁心 偏磁 剩磁 逆变焊机 电弧啸叫 nanocrystalline magnetic core magnetic bias remanence inverter welding machine arc whistling TG434 国家重点研发计划重点基础材料技术提升与产业化项目资助（2016YFB0300500） 2022-03-08 12 50
