摘要

磁粉磁芯由于其独特的磁性能，被广泛应用于电力电子领域的许多电感中。这项工作研究了一些由铁和FeCo颗粒制成的低成本磁粉芯的滞后曲线，用标准化系统测量。实验表明，对于这些表现出显著损失的样品，在较高频率下使用经典设备的局限性。测得的随频率变化的磁滞曲线显示出不同的有效磁导率。研究结果有助于比较这些粉末芯的总磁损耗随频率增加的变化规律。

Frequency Dependent Hysteresis Curves of Fe and FeCo Magnetic Powder Cores

Magnetic powder cores are involved in many inductors used in power electronics, due to their tailored magnetic properties. This work investigates the hysteresis curves, measured by a standardized system, of some low-cost magnetic powder cores made from Fe and FeCo particles. The experiments show the limits of using classical equipment at higher frequencies for these samples that exhibit significant losses. The measured frequency dependent hysteresis curves show various effective magnetic permeabilities. The results are useful to compare the evolution of total magnetic losses of these powder cores with the frequency increasing.
