Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Design of LLC Magnetically Integrated Transformer Based on Nanocrystalline Soft Magnetic Composite Leakage Core

CES Transactions on Electrical Machines and Systems
Magnetic integration technology can reduce the printed circuit board (PCB) size of inductor-inductor-capacitor (LLC) converters. However, conventional methods for adjusting leakage inductance by modifying the transformer's air gap exhibit low sensitivity

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

Advanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Comparative Analysis in Single-Phase Induction Motors: Analytical, Numerical, and Load Tests

IEEE Access
Single-phase induction machines have two windings in the stator to produce a rotating field: a main winding and an auxiliary winding. The stator slot leakage inductance varies with the position of the coils within the slot.

Defining and Computing Equivalent Inductances of Gapped Iron Core Reactors

, 2011
The paper revisits the fundamental definitions and explores computational alternatives of equivalent inductances of gapped iron core reactors. Unlike in a transformer, the physical meaning of component inductances of a reactor is subject to uncertainty ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

A Novel Method of Estimating Induction Motor q-axis Leakage Inductance

Kongzhi Yu Xinxi Jishu, 2010
The q-axis leakage inductance Ls is always used in the control of induction motor. The parameters generally come from the analysis and calculation of the magnetic field or magnetic path, so some errors are hard to avoid.

Impact of Asymmetrical Leakage Inductance on a 380 V–12 V LLC Converter with Synchronous Rectifier for DC Transformer Application

Energies
High-density 380 V–12 V LLC resonant converters typically employ planar transformers with integrated leakage inductance. To achieve Zero-Voltage Switching (ZVS), an air gap is introduced to adjust the magnetizing inductance (Lm). However, this gap alters

Analytical calculation of resonant inductance for zero voltage switching in phase-shifted full-bridge converters [PDF]

, 2013
The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the ...
