Unified magnetic equivalent circuit-based model of two-core Sen transformer for low-frequency electromagnetic transients and its numerical calculation

Transformer Modelling Considering Power Losses Using an Inverse Jiles-Atherton Approach

“…Compared to mathematical models without a physical basis, models with a physical background such as the Preisach and Jiles-Atherton models are more applicable in the engineering field because they can more accurately describe magnetization process under any magnetic excitation [14][15][16][17] in both permanent and transient conditions [18,19]. Both Preisach and Jiles-Atherton models use the magnetic field H as an independent variable [20], which allows to simulate the hysteresis and saturation characteristics of ferromagnetic materials [21].…”
