On the variation with flux and frequency of the core loss coefficients in electrical machines [PDF]
, 2006 A model of core losses, in which the hysteresis coefficients are variable with the frequency and induction (flux density) and the eddy-current and excess loss coefficients are variable only with the induction, is proposed. A procedure for identifying the

Iron Losses Prediction with PWM Supply Using Low and High Frequency Measurements: Analysis and Results Comparison [PDF]
, 2008 In this paper, two different methods for iron loss prediction are analyzed. The first method is based on the classical separation of loss contributions (hysteresis, eddy-current, and excess losses).

The Mitigation of Eddy-Current Losses in Ferromagnetic Samples Produced by Laser Powder Bed Fusion
IEEE Access, 2022 We study the use of topology optimization in the design of low-loss ferromagnetic core structures for additively manufactured electrical machines. The test case was a simple toroid core with a primary and a secondary winding.

Power Losses Models for Magnetic Cores: A Review
Micromachines, 2022 In power electronics, magnetic components are fundamental, and, unfortunately, represent one of the greatest challenges for designers because they are some of the components that lead the opposition to miniaturization and the main source of losses (both ...

Minimum Loss Operation and Optimal Design of High-Frequency Inductors for Defined Core and Litz Wire
IEEE Open Journal of Power Electronics, 2020 This paper studies the loss-optimal design of a power inductor employed in a 2 kW, 400 V input DC-DC converter. The design of an inductor is subject to a large number of design parameters and the implications of the different design parameters on the ...
