A transformer model based on the Jiles-Atherton theory of ferromagnetic hysteresis [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2008
This paper presents a transformer model that is useful for lowfrequency applications. To describe the iron-core magnetic behavior, the Jiles Atherton hysteresis model is used, which is able to generate minor asymmetric loops and remanent flux.
