Abstract

This paper presents details of a study undertaken to measure the magnetic properties of magnetic powder cores and assess the applicability of a numerical modeling technique for the prediction of losses under a range of nonstandard magnetizations. The modeling technique aims to allow prediction of magnetic properties under a wide range of magnetizing conditions, including pulse width modulation (PWM) magnetization, based on obtaining limited information of the material's near-dc magnetic properties and electrical resistivity. This approach, based on a concept known as magnetic viscosity, offers significant advantages and has been shown previously to be accurate in its application with soft magnetic lamination materials.
