The ability to provide an accurate measure of core losses is of considerable significance to magnetic and thermal design. This topic is becoming increasingly important due to the introduction of new semiconductor technologies, such as silicon carbide and gallium nitride, able to operate at increasingly higher frequencies. These new materials requiredifferent types of filters and inductive components. Choosing the right components is today a quite difficult task. Although there is a profound knowledge about the characteristics and chemical-physical properties of materials, it is not easy to compare different types of ferrite cores or chokes, choosing the one which best fits our design. This article will explain how to find a solution to this problem, introducing a technique that provides an accurate measurement of core losses.
