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.

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

An Ultra-Low Bending Loss Negative Curvature Hollow Core Fiber With a Polygon Jacketing Layer
IEEE Photonics Journal, 2023 We design and simulate a new type of hollow-core antiresonant fiber with the polygon jacketing layer. Through numerical calculations, the confinement loss is approximately 0.003 dB/km at 1.45 μm and the bandwidth is ∼ 410 nm @

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 ...

Non‐linear model of the switched reluctance motor with included core losses’ effects
IET Electric Power Applications, 2021 To accurately predict motor performance, considering the effects of core losses is of great importance, especially at speeds much higher than the base where the core losses represent a considerable portion of the total drive losses.

Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core
Photonics, 2022 We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to
