摘要
设计加工了一套可用于测量环形磁芯在8~12 T/μs恒定磁化速率下脉冲性能的实验平台,该实验装置主要包括脉冲形成网络、放电开关、匹配负载及被测磁芯。基于该平台对国产的铁基纳米晶磁芯的磁化曲线进行了测试,得到了铁基纳米晶磁芯在200~300 ns范围内的损耗和非饱和脉冲导磁率。实验结果表明:铁基纳米晶磁芯的相对脉冲导磁率随着磁感应增量增大及工作脉宽减小而减小,磁芯损耗则逐渐增大。
Abstract
A test stand was developed to measure magnetic properties of toroidal magnetic cores at a constant magnetization rate of 8-12 T/μs. The test stand consists of pulse forming network(PFN), discharge switches, load and magnetic core. On the basis of the test stand, the magnetization curves of domestic nanocrystalline magnetic core were measured. The energy losses and relative permeability at 200-300 ns pulse width of toroidal magnetic cores were also tested. The experiment results show that the relative pulse permeability of the nanocrystalline magnetic core decreases with increasing the magnetic induction increment and decreasing the pulse width, while the energy loss increases.
