Abstract

Amorphous and nanocrystalline magnetic cores allow lighter, smaller and more energy efficient designs of many industrial high frequency applications such as: adjustable speed drives (ASD), invertors, uninterruptible and switched-mode power supply (UPS and SMPS). The aim of this paper is to present a complex comparison between two soft magnetic materials, frequently used in electromagnetic devices, that operate in a wide range of frequencies. Aspects regarding their first magnetization curves, magnetic permeability, and energy losses at different frequencies are analyzed. Additionally, a magnetic loss separation study, using Bertotti method, for each investigated material is performed.
