The Jiles-Atherton (J-A) model is widely used in the modeling of the magnetization process of magnetic cores, but its simulation accuracy in the nonlinear section of hysteresis loops is low due to its theoretical defect. To improve its simulation accuracy, a method for reducing simulation errors arising from the original J-A model is proposed, and thereby a modified J-A model is established. Measured hysteresis loops of nanocrystalline alloy cores at different frequencies are simulated using the original J-A model, and simulation errors are concentrated mainly in the nonlinear section of the hysteresis loops. Simulation results of the original J-A model are modified using the modified J-A model, and thereby the simulation errors in the nonlinear section are greatly reduced. This indicates that the modified J-A model can more accurately describe the magnetization process of cores.

Didier Power transformer model in railway applications based on bond graph and parameter identification. (2020) IEEE Transactions on Transportation Electrification.Abstract-Validation and verification are the most important issues in railway applications due to cost and security reasons. Therefore, having a model of the system would be necessary in this case. Due to non-ideal test conditions in industrial applications, an accurate parameter identification process has to be defined. In this paper, bond graph method is used to model energy exchanges within components of a traction chain. More precisely, the nonlinear transformer model and its parameter identification is studied. In the case of non-ideal test conditions, the usual Jiles-Atherton parameter identification procedure can not be performed. Regarding state of the art, the Jiles-Atherton parameter identification is discussed. It is highlighted that an uncomplete hysteresis cycle, including extremum point and coercive field are mandatory for an accurate parameter identification. The proposed identification process is applied to a real application case. The obtained parameters are then inserted into the overall system model. The consecutive simulations are compared to experimental data obtained through traction chain test bench.

Reducing induction motor losses is very important because of the fulfilment of increasingly stringent requirements set by international regulations for reducing electricity consumption. Since core losses begin to dominate in motors operating at higher frequencies the exact calculation becomes more and more important. The common view is that losses due to higher harmonics caused by stator and rotor slotting constitute an important part of losses in the motor core. Proper calculation of the core losses requires inclusion both hysteresis and eddy current phenomena. For the hysteresis simulation, method included in package Opera 3D has been used. Using that model it was possible to investigate flux behavior at high frequency like as for higher harmonics field. Next part is focused on practical determining of proper method for higher harmonics losses limitation.
