Improved Rectangular Extension of Steinmetz Equation Including Small and Large Excitation Signals with DC Bias

Year: 2025

Type: article

Abstract: The core loss of the ferrite-based magnetic components is usually characterized by the well-known Steinmetz equation and its derivatives. This occurs when the magnitude of the excitation signal is high enough; otherwise, the core loss is defined by the complex permeability. These two models are based on different assumptions, and thus, this paper aims to combine the large- and small-signal core loss models into a single, unified model. Moreover, the paper presents improvements to the existing state-of-the-art core loss model, specifically regarding the influence of the switching duty-cycle of rectangular excitation signals and the DC bias.
