On Simplified Calculations of Leakage Inductances of Power Transformers

Energies, 2020
This paper deals with the problem of the leakage inductance calculations in power transformers. Commonly, the leakage flux in the air zone is represented by short-circuit inductance, which determines the short-circuit voltage, which is a very important ...

Power module stray inductance extraction: Theoretical and experimental analysis

ETRI Journal, 2021
We propose a stray inductance extraction method on power modules of the few‐kilovolts/several‐hundred‐amperes class using only low voltages and low currents.

Evaluation Model of Loop Stray Parameters for Energy Storage Converter of Hybrid Electric Locomotive

IEEE Access, 2020
When the silicon carbide (SiC) power module is applied to the energy storage converter of a hybrid locomotive, under the action of di/dt and loop stray inductance, it is easy to produce excessively high voltage overshoot, which affects the battery life ...

Greatly Improved Small Inductance Measurement Using Quartz Crystal Parasitic Capacitance Compensation

Sensors, 2010
Generally, quartz crystal inductance frequency pulling in oscillators is very low and therefore is not often used in practice. The new method of improving frequencypullability uses inductance to compensate for quartz stray capacitances.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Leakage Inductances of Transformers at Arbitrarily Located Windings

Energies, 2020
The article presents the calculation of the leakage inductance in power transformers. As a rule, the leakage flux in the transformer window is represented by the short-circuit inductance, which affects the short-circuit voltage, and this is a very ...

Parameters Design and Optimization of SiC MOSFET Driving Circuit with Consideration of Comprehensive Loss and Voltage Stress

Micromachines, 2023
In conventional parameters design, the driving circuit is usually simplified as an RLC second-order circuit, and the switching characteristics are optimized by selecting parameters, but the influence of switching characteristics on the driving circuit is
