This paper motivates the development of sophisticated data–driven models for power magnetic material characteristics.Core losses and hysteresis loops are critical information in design process magnetics, yet physics behind them is not fully understood or directly applicable. Both change each depend heavily on electrical operating conditions (e.g., waveform, frequency, amplitude, dc bias), mecha...

Version 1b, August 1994 A procedure for modeling and simulation of arbitrary nonlinear magnetics components is presented. A set of electromagnetic primitives is described as implemented in Verilog-A. The primitives include cores, gaps, and windings that are combined to model ferromagnetic inductors and transformers. The physics of the ferromagnetic core model is described. The model is used to ...

Preisach modeling, long known in the area of magnetics, has introduced mathematical abstraction to the modeling of the highly nonlinear and complex phenomenon of hysteresis. The 2D Preisach-type models presented here, departing slightly from the classical formulation, waive some of its limitations while maintaining the major advantages of simplicity and speed in calculations. Results on differe...

Magnonics addresses the physical properties of spin waves and utilizes them for data processing. Scalability down to atomic dimensions, operation in GHz-to-THz frequency range, utilization nonlinear nonreciprocal phenomena, compatibility with CMOS are just a few many advantages offered by magnons. Although magnonics is still primarily positioned academic domain, scientific technological challen...

New planar construction alternatives for blending the various power magnetic components of switch mode power processing circuits and systems are presented. These unique approaches are based on the use of core designs with multiple winding areas and core sections which provide common flux paths for transformer and inductor operations, arranged so as to minimize magnetic interactions and core mat...
