On voltage stability regions and voltage secondary control
PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003This paper presents some new results on the geometry of the reactive load-flow problem. These results have implications in order to asses the system margin to the voltage collapse and to design a secondary voltage control aimed to avoid the voltage collapse.

Most of the treatment in the text so far covered the special case of the transfer function which happened to be the impedance one. In that case, input is current and output is voltage. While that is one of the most relevant cases in circuit theory, it by no means is the only one!

The voltage-sensor structure in a voltage-gated channel
Trends in Biochemical Sciences, 2005A recent electron paramagnetic resonance study of KvAP, a prokaryotic voltage-gated channel, in its lipid native environment has revealed the location of the transmembrane segments, the connecting loops and the relative position of the voltage-sensing charges.

Effects of arc voltage on recovery voltage
Electrical Engineering, 1958THE CHARACTERISTICS of the interrupting device may have an appreciable effect on the recovery voltage obtained on interrupting an a-c circuit. This effect may appear as (a) an abrupt cutting off of the current, (b) the introduction of an arc voltage, or (c) the gradual introduction of a resistance.

High Voltage Versus Low Voltage
Physical Therapy, 1986To the Editor: The conclusions stated in the article “High Voltage Versus Low Voltage Electrical Stimulation: Force of Induced Muscle Contraction and Perceived Discomfort in Healthy Subjects” (Physical Therapy 66:1209–1214, 1986) contradict an extensive body of literature1–5 that suggests that optimal pulse duration for neuromuscular stimulation in ...

Using the Pull-In Voltage as Voltage Reference
2001The reproducibility of the pull-in voltage of a single side clamped free-standing beam has been investigated for application as a DC voltage reference. A 2 mm long beam has been fabricated in an epipoly process with, at the tip, poly-poly electrodes extending into the axial direction for electrostatic lateral deflection and a comb-drive operating in ...

Voltage gradients on high-voltage lines
Electrical Engineering, 1955AKNOWLEDGE of the voltage gradient which exists at the surface of a transmission-line conductor is necessary in many instances. This knowledge is especially important in studies regarding corona losses and radio interference.

Voltage Sag Detection Technique for a Dynamic Voltage Restorer
IEEE Transactions on Industry Applications, 2003Dynamic voltage restorers (DVRs) are used to protect sensitive loads from the effects of voltage sags on the distribution feeder. This paper presents and verifies a novel voltage sag detection technique for use in conjunction with the main control system of a DVR.

Voltage regulation optimization in low voltage network based on Voltage Quality Index
Proceedings of the 2014 15th International Scientific Conference on Electric Power Engineering (EPE), 2014The paper deals with an optimization procedure in terms of a network voltage parameters improvement. A software based approach is used to select optimal type of voltage regulator, its power and ideal location for application in a Low-Voltage (LV) test network, where it is required to enhance Voltage Quality (VQ).

Voltage-to-Frequency Converter for Ultra-Low-Voltage Applications
2019 42nd International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2019The paper is focused on the design and analysis of a Voltage-to-Frequency Converter (VFC) that was implemented in 130 nm CMOS technology. The proposed VFC was designed using the bulk-driven technique and can reliably work with the power supply voltage of 0.4 V.
