A Reliable Ultrafast Short-Circuit Protection Method for E-Mode GaN HEMT

IEEE transactions on power electronics, 2020
A unique three-step short-circuit protection method is proposed for the 650-V enhancement mode (E-mode) gallium nitride high-electron mobility transistor (GaN HEMT).

Gate Failure Physics of SiC MOSFETs Under Short-Circuit Stress

IEEE Electron Device Letters, 2020
The unique gate failure mode of SiC MOSFETs is often identified but has not been fully understood yet. In this letter, post-failure cell inspections demonstrate that its main cause is the crack at the SiO2 dielectric layer with melted source aluminum ...

Micro-Short-Circuit Diagnosis for Series-Connected Lithium-Ion Battery Packs Using Mean-Difference Model

IEEE transactions on industrial electronics (1982. Print), 2019
Micro-short-circuit (MSC) is a latent risk in power batteries, which may give rise to thermal runaway and even catastrophic safety hazards. The motivation of this paper is to quantitatively analyze MSC in an initial stage, particularly for lithium-ion ...

MIG short-circuit welding: on the short circuit duration

Journal of Physics D: Applied Physics, 1986
The short circuit duration in MIG short-circuit welding is evaluated using the Bless relationship which refers only to mass of drops and surface tension to molten metal. In a typical experiment, the experimental values of short circuit duration fit with the expected ones, considering acceptable value for the surface tension of molten iron.

Assessing Strength of Multi-Infeed LCC-HVDC Systems Using Generalized Short-Circuit Ratio

IEEE Transactions on Power Systems, 2019
In this paper, a generalized short-circuit ratio (gSCR) is proposed for assessing the grid strength of multi-infeed LCC-HVDC (MIDC) systems by the theoretical analysis of the relationship between static voltage stability and grid strength.

The conventional short-circuiting technique under-short-circuits most epithelia

The Journal of Membrane Biology, 1981
The relationships among ion current, membrane potential difference, and resistance of an epithelium are studied. The short-circuit technique introduced by Ussing and Zerahn does not completely short circuit the epithelium if the series resistance parallel to the cell layer between the voltage electrodes is not properly compensated.

Short-circuited neuron: a note

Neuroscience, 2000
Here, we demonstrate in a direct electrophysiological experiment that a neuron can form electrical connections to itself. An isolated identified neuron with a long axon was plated in culture and the axon was looped so that its distal end contacted the cell body.

Assessing Impact of Renewable Energy Integration on System Strength Using Site-Dependent Short Circuit Ratio

IEEE Transactions on Sustainable Energy, 2018
The increasing penetration of renewable energy sources (RESs) can challenge both power system planners and operators to maintain system reliability. Potential power system stability issues may arise when a large amount of RESs are connected to a weak ...
