Abstract

In recent years, with the rapid development of new energy power system and energy Internet, how to select excellent magnetic core materials of high-frequency transformers and solve the loss problem of transformers under high-frequency conditions is one of the current research hotspots. As an ideal core material for high-frequency transformers, nanocrystalline iron cores have excellent magnetic properties and have attracted extensive interest in the field of electrical engineering. In order to understand the mechanism of magnetic properties of nanocrystalline materials under high frequency sinusoidal conditions, a three-dimensional mesoscopic model of nanocrystalline magnetic core was constructed by using micromagnetic simulation software. The mechanism of high-frequency magnetization reversal is revealed by studying the process of magnetic domain from forward saturation to reverse saturation, and the influence of frequency on magnetization rate and hysteresis is studied. The results show that the magnetization reversal process of nanocrystalline magnetic core is faster at higher magnetic field frequency and has more obvious hysteresis effect.
