A voltage‐controlled resistor for a linear voltage‐controlled oscillator

Electronics and Communications in Japan (Part II: Electronics), 1996
AbstractTo realize a linear voltage‐controlled oscillator (VCO), a voltage‐controlled resistor (VCR) whose reciprocal resistance is linear with respect to the control voltage Vcwas fabricated and tested. The VCR was composed of an analog multiplier (AM) and an operational amplifier (OA). The. static effective resistanceReof the VCR varied asR−1e=R−1(1 +

Rectifier Voltage Control

Transactions of the American Institute of Electrical Engineers, 1926
Lack of voltage control is one of the objections which have been made to the use of rectifiers. The author describes a method of voltage control for rectifiers based on the use of a saturated core interphase transformer. Saturation of this device produces a gradual change from two three-phase rectifiers operating in parallel to one six-phase rectifier ...

Voltage control in low voltage systems with controlled low voltage transformer (CLVT)

CIRED 2012 Workshop: Integration of Renewables into the Distribution Grid, 2012
The rapidly growing penetration of Germany's distribution grids with all forms of DG causes a high pressure on voltage stability according to several normative guidelines. Beside conventional network reinforcements increasing short-circuit-power, new technical alternatives awake interest.

Interaction among voltage controlling devices and voltage control effect identification

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
This paper presents a method to verify the adequacy of voltage control actions in the operation of electrical systems. The assessment is done through a sensitivity matrix, whose characteristics are presented and discussed. The goal is to identify whether the usual logic of voltage controlling equipment is occurring normally or not.

Voltage control of multiple step voltage regulators by renewing control parameters

2014 Power Systems Computation Conference, 2014
This paper presents a novel method of determining the control parameters and a voltage control method for multiple step voltage regulators (SVRs) in a single feeder. The main feature of the proposed method is the updating of the control parameters at constant intervals to minimize the amount of voltage violations and the tap operation times of the SVRs

On voltage stability regions and voltage secondary control

PowerTech Budapest 99. Abstract Records. (Cat. No.99EX376), 2003
This 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.

"Semiconductor voltage controllable reactance"

IRE Transactions on Electron Devices, 1955
A germanium alloy-junction diode has been developed which is useful as a voltage controlled reactance up to and including ultra high frequencies. Special attention has been paid to electrical losses and lead inductance. Typical performance at 500 mc/s and 6 volts bias is a capacitance of 30 µµfd with a change in capacitance at this voltage of 2 µµfd ...

Voltage-controlled photonic oscillator

Optics Letters, 2010
We report the development and demonstration of an X-band voltage-controlled photonic oscillator based on a whispering gallery mode resonator made of an electro-optic crystalline material. The oscillator has good spectral purity and wide, agile, linear tunability.
