Theoretical Assessment of Electrical Steel Magnetic Components During PWM-Type Conversion: A Comparison Between Two Hysteresis Models
Year: 2024
Type: conference-paper
Abstract: Accurate simulations of frequency-dependent hysteresis cycles and the associated power losses within electrical steel magnetic components during PWM -type conversion are essential, as they provide crucial insights into converter efficiency and performance. To this end, this study aims to compare two hysteresis models; one combines the Maxwell diffusion equation and a fractional differential equation material law, and the other is based on Bertotti's loss separation theory, extended to include the skin effect. Criteria such as accuracy, simulation time, and number of parameters, among others, aid in determining the most suitable simulation approach. This paper gives precise definitions of the simulation methods, presents comparative results, and draws specific conclusions pertinent to the industrial context.
