Analysis of influencing factors of short-circuit spark discharge in electric potential capacitance circuit

Gong-kuang zidonghua, 2020
Most of existing models and methods for research of capacitive circuit spark discharge and high-power intrinsic safety power supply only consider discharge characteristics of energy storage elements during discharge process， and do not consider influence

A Scheme of DC-side Short-circuit Protection for Bi-directional Converterin Urban Rail Traction Power Supply System

Kongzhi Yu Xinxi Jishu, 2021
Using bi-directional converters for traction power supply in urban rail transit, traditional PWM rectifiers cannot meet the requirement of DC feeder protection for 27 kA short-circuit current with 120 ms continuous time.

Transistor current and voltage limiting switch [PDF]

, 1970
Limiting circuit protects the main power supply of electronic modules and limits the current drawn by each module should a short circuit occur. It limits current within one mA when used with direct current of either polarity, or with pulse or ac power ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Influence of Short‐Circuit Current Nonperiodic Component Increasing on Radial Dynamic Stability of Power Transformer Winding Under Reclosing

IET Electric Power Applications
As one of the key main equipment of the power system, the transformer directly affects the safe and reliable operation of the system. In the process of transformer reclosing, the internal electromagnetic environment is obviously different from that of ...

Design of high-power intrinsically safe power supply based on fault current change rate

Gong-kuang zidonghua, 2021
In order to solve the problems of low output power, poor protection effect, and slow dynamic response speed of existing intrinsically safe power supply, a high-power intrinsically safe power supply based on fault current change rate is designed.
