【摘要】：对Fe73.5Cu1Nb3Si13.5B9纳米晶铁芯分别进行普通热处理与横磁处理,并检测铁芯经两种热处理后的各项磁性能。获得了各频率下损耗与幅值磁密的关系。结果表明,横磁处理降低损耗效果较明显,该方法在高频电力电子变压器铁芯领域具有潜在应用前景。损耗分离结果表明,横磁处理后,磁滞损耗、涡流损耗、剩余损耗在总损耗中所占比例分别为不变、升高、降低。横磁处理后,磁畴结构改变,以磁矩旋转磁化为主要磁化方式,降低畴壁共振造成的异常损耗是除降低磁滞损耗外,降低总损耗的另一原因。
[Abstract]:The Fe73.5Cu1Nb3Si13.5B9 nanocrystalline cores were ordinary heat treatment and transverse magnetic treatment, and the detection of the core magnetic properties of two kinds of heat treatment. The relationship between the density and amplitude of each frequency magnetic loss was obtained. The results show that the transverse magnetic treatment reduces the loss of the effect is obvious, this method has a potential application prospect in high frequency power electronic transformer core loss field. Separation results show that the transverse magnetic treatment, hysteresis loss, eddy current loss and residual loss in the total loss ratio was unchanged, increased, decreased. The transverse magnetic treatment, magnetic domain structure change, with magnetic moment rotation magnetization as the main mode of magnetization, reduce the abnormal loss caused by domain wall resonance in addition to reduce hysteresis loss, reduce the total loss of another reason.
