Fe-6.5 wt%Si Powder Cores with Low Core Loss by Optimizing Particle Size Distribution

Metals, 2020
The effect of different particle size distribution of Fe-6.5 wt%Si powder on the microstructure and soft magnetic properties of the corresponding soft magnetic powder cores (SMPCs) was investigated.

The impact of the mixing properties within the Antarctic stratospheric vortex on ozone loss in spring [PDF]

, 2001
Calculations of equivalent length from an artificial advected tracer provide new insight into the isentropic transport processes occurring within the Antarctic stratospheric vortex. These calculations show two distinct regions of approximately equal area:

Magnetization-Dependent Core-Loss Model in a Three-Phase Self-Excited Induction Generator

Energies, 2018
Steady-state, transient, as well as dynamic analyses of self-excited induction generators (SEIGs) are generally well-documented. However, in most of the documented studies, core losses have been neglected or inaccurately modeled.

Core Structure and Electromagnetic Field Evaluation in WPT Systems for Charging Electric Vehicles

Energies, 2018
The electromagnetic field (EMF) in a wireless power transfer (WPT) system needs to couple inductively between the primary and the secondary coils through a large air gap, thus giving the system a loosely coupled characteristic.

Stability of solitons in PT-symmetric couplers [PDF]

, 2011
Families of analytical solutions are found for symmetric and antisymmetric solitons in the dual-core system with the Kerr nonlinearity and PT-balanced gain and loss. The crucial issue is stability of the solitons.

Differential Inverters: A General Design Procedure Integrating a Novel Power Losses Modeling Approach for Utilized DC–DC Modules at Different Modulation Schemes

IEEE Access, 2023
Differential inverters develop the PWM of internal DC-DC modules by correlating fundamental frequency of load with high switching frequency to maintain inherent characteristic operation and achieve pure higher/lower AC output voltage with smaller size ...

Temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites

, 2010
The temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites was investigated. Co2+ ions are known to lead to a compensation of the magneto-crystalline anisotropy in Ni-Zn ferrites, at a temperature depending on the cobalt content and ...
