Abstract

There is currently a need of magneto-electrical apparatus such as inductor and transformer that operate at hundreds of kHz up to several MHz, or even higher frequency. The material based on polymer-bonded magnetic powder has a feature of the magnetic property and can be used as the power transformer, electromagnetic interference shielding, and power inductor, etc. It is so promising that this material has been found good results for power conversion and screening. In this work, a magnetic ring core was fabricated using the composite of the magnetic powder and polymer, nickel, rare earth materials and poly(methyl methacrylate) (PMMA). This ring core was used as the output filter in a buck converter, and the electrical properties were studied.
