Hysteresis Modeling for Power Magnetic Devices Based on Magnetic Circuit Method

Research output: Contribution to journalReview articlepeer-review


This paper introduces the latest research achievements on the hysteresis modeling for power magnetic devices based on the magnetic circuit method. First, the magnetic circuit model considering the magnetic hysteresis behavior is derived. Next, this magnetic circuit model is developed to the reluctance network model, to analyze more complicated devices such as an electric motor. Furthermore, this magnetic circuit model is improved to take the dynamic hysteresis characteristics including the skin effect into account. Finally, the prediction method of the deteriorated hysteresis loops in core material due to machining process is established.
