[Abstract]:Iron-based nanocrystalline materials are widely used in pulsed magnetic elements because of their excellent soft magnetic properties. In order to better guide the design and performance analysis of pulsed magnetic elements, it is necessary to test the pulse magnetization characteristics of Fe-based nanocrystalline cores according to the applied environment. In this paper, based on the LC ferroresonance discharge test platform, the initial magnetization curve and hysteresis loop of Fe-based nanocrystalline materials with high and low remanence magnetization rates and magnetic induction increments are obtained by selecting appropriate measuring circuits. The change trend of key magnetic parameters such as pulse permeability and loss is obtained. The mathematical relations among impulse permeability, loss, magnetization rate and magnetic induction increment are established by curve fitting method, which fully reflect the pulse magnetization characteristics of Fe-based nanocrystalline cores. Based on the basic data of pulse magnetization characteristics of Fe-based nanocrystalline cores, it is possible to accurately analyze the working characteristics of typical pulsed magnetic elements and optimize their design.
