Voltage fluctuations in small conductors
Physical Review B, 1987The mean-squared voltage fluctuations of an ensemble of disordered conductors, measured between probes less than an inelastic scattering length apart, are independent of the separation of the probes. The mean-squared fluctuations of the conductance can exceed ${e}^{2}$/h by many orders of magnitude. To obtain these results, it is essential to take into

Voltage Fluctuations in Neurons: Signal or Noise?
Physiological Reviews, 2011Noise and variability are fundamental companions to ion channels and synapses and thus inescapable elements of brain function. The overriding unresolved issue is to what extent noise distorts and limits signaling on one hand and at the same time constitutes a crucial and fundamental enrichment that allows and facilitates complex adaptive behavior in an

Stable Frequency Response for Multi-Terminal MMC-HVDC System with DC Voltage Fluctuations
Annual Conference of the IEEE Industrial Electronics Society, 2019This paper presents a control strategy for a Multi-Terminal MMC-HVDC system to enhance the frequency response of AC grids. Using power sharing of both upper and lower arms of MMC combined with a basic equation of control functions, the proposed upper and

Fluctuations of High Voltage Impedance
2020A 59-year-old man with ischemic cardiomyopathy had a single-chamber Medtronic Entrust™ ICD and Sprint Fidelis™ Model 6949 dual-coil true bipolar lead implanted over 2 years ago after out-of-hospital VF. His NYHA Class is III and left ventricular ejection fraction is 34%.

SMES Based Dynamic Voltage Restorer for Voltage Fluctuations Compensation
IEEE Transactions on Applied Superconductivity, 2010This paper presents a superconducting magnetic energy storage (SMES) based dynamic voltage restorer (DVR) to protect consumers from the grid voltage fluctuations. Due to the characteristic of high energy density and quick response, a superconducting magnet is selected as the energy storage unit to improve the compensation capability of DVR.

A Synchrosqueezing Transform-Based Hybrid Method for Voltage Fluctuations Assessment
IEEE Transactions on Power Delivery, 2018Voltage fluctuations caused by rapid reactive power consumption of loads and photovoltaic or wind generator output variations may produce flickers and cause undesired effects on electric power components and human eyes.

Dependence of Voltage Fluctuation Severity on Clipped Sinewave Distortion of Voltage
IEEE Transactions on Instrumentation and Measurement, 2021The article presents the novel findings on the dependence of voltage fluctuation severity on voltage distortion caused by power electronic loads. The results indicate the need to modify the recommended limitation of the IEC flickermeter bandwidth to cut-off frequency at least 450 Hz by the IEC standard, to consider the possible obnoxious voltage ...

Calculation of Three-Phase Voltage Fluctuation
2005/2006 PES TD, 2006An accurate computation algorithm has been presented in this paper to calculate the voltage fluctuation components of three-phase circuits. Three voltage vectors have been used and compared. After the voltage waveforms of three-phase circuits have been recorded, the voltage vectors are calculated.
