Research on Optimization Method of Short-Circuit Current-Limiting Measures Based on Combination Assignment

Energies
This paper puts forward a selection principle and an optimization configuration method for short-circuit current-limiting measures to address the increasingly severe short-circuit current-exceeding problem brought about by the high-speed development of ...

Ultra-stable oscillator with complementary transistors [PDF]

, 1974
A high frequency oscillator, having both good short and long term stability, is formed by including a piezoelectric crystal in the base circuit of a first bi-polar transistor circuit, the bi-polar transistor itself operated below its transitional ...

Comparing the Effect of Semi‐Immersive Virtual Reality, Computerized Cognitive Training, and Traditional Rehabilitation on Cognitive Function in Multiple Sclerosis: A Randomized Clinical Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...

An improved discharge technique for excimer lasers [PDF]

, 1990
The further development of discharge excimer lasers depends upon a better degree of control over the discharge stability. A problem is the large difference between the breakdown and steady-state voltage which requires a time dependent impedance of the ...

Short-circuit protection for direct-current sub-stations [PDF]

Journal of the American Institute of Electrical Engineers, 1920
The author includes an outline of the progress made in protection of direct-current machinery from short circuits since the publication of a paper at Atlantic City on this subject. The improvements mentioned include the refinement and perfection in details of the flash barriers; a new design of high-speed circuit breaker for both direct-current ...

PV control system based on short-circuit current

2013 IEEE 8th International Symposium on Applied Computational Intelligence and Informatics (SACI), 2013
The article is focused on specific issues arising for a photovoltaic panel (PV). In this case, the short circuit current is measured to determine the value of prescribed current corresponding to maximum power point. The results obtained by imposing a load resistance with this method are energy maximum possible, thus justifying the usefulness of this ...

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Calculation and Analysis of the Strands Short-Circuit in Stator Transposition Bar for Large Generators

IEEE Access, 2019
The transposition of the stator bar is an important technique in the large generator design. Under the excitation of vibration and thermal effect, the insulation of strand is easily damaged, which leads to short-circuiting fault, and adversely impacts ...

Design study of a thermocouple power sensor as a monolithic fin-line [PDF]

, 2011
Making traceable power measurements above 110 GHz using current measurement technologies is challenging. We investigate a design of power sensor consisting of a thermocouple-based integrated circuit (IC) mounted as a finline component in WR-6 waveguide ...

Influence of short circuit conditions on IGBT short circuit current in motor drives [PDF]

2011 Twenty-Sixth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2011
Protecting the IGBTs against short circuit conditions is a critical aspect of the Industrial motor drive design. The SC (short circuit) conditions can occur in a variety of ways in an industrial environment. The SC applied across the motor drive terminals result in a different fault current profile than a SC that happens at the motor terminals or ...
