The article describes a feedback Preisach hysteresis model equivalent circuit implementation of a medium frequency single-phase transformer being a part of a high power and high efficiency DC-DC converter. The macroscopic models of magnetic hysteresis are introduced and the feedback Preisach model is selected for further analysis. The hysteresis model is developed for a prototype transformer and the hysteresis loops are compared against a measurement. The equivalent circuit implementation of the hysteresis model is proposed and analysed. The equivalent circuit model is validated in no load operation and compared with a measurement.
