Short-circuit protection of LLC resonant converter using voltages across resonant tank elements

The Journal of Engineering, 2015
This paper describes two methods for the short-circuit protection of the LLC resonant converter. One of them uses the voltage across the capacitor and the other uses the voltage across the inductor of the resonant tank.

Fast Detection of Current Transformer Saturation Using Stacked Denoising Autoencoders

Energies, 2023
Malfunctions in relay protection devices are predominantly caused by current transformer (CT) saturation which produces distortion in current measurements and disturbances in power system protection.

Current Limiting Characteristics of Parallel-Connected Coated Conductors for High-Tc Superconducting Fault Current Limiting Transformer (HTc-SFCLT) [PDF]

, 2009
We have been developing superconducting fault current limiting transformer (SFCLT) as a superconducting transformer with current limiting function. As the step-5 of the SFCLT project for the up-graded ratings of current and voltage, in this paper, we ...

Emapalumab for Immune Effector Cell‐Associated Hemophagocytic Lymphohistiocytosis‐Like Syndrome Following CD19‐Directed CAR‐T in Two Patients With B‐ALL: Clinical and Biomarker Correlates

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Immune effector cell‐associated hemophagocytic lymphohistiocytosis‐like syndrome (IEC‐HS) is a life‐threatening hyperinflammatory toxicity distinct from cytokine release syndrome (CRS) and neurotoxicity following chimeric antigen receptor T‐cell (CAR‐T) therapy. In a single‐institution retrospective cohort of pediatric and young adult patients

The two-stage current transformer [PDF]

Journal of the American Institute of Electrical Engineers, 1922
This paper presents a brief discussion of the current transformer as used with measuring and controlling apparatus with special reference to the degree of accuracy which can be attained in the ratio and phase angle. A new type of current transformer is then described, in which it is possible to secure much higher accuracy with a given amount of iron ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.
