Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

Using voltage data down to the consumer level is essential for grid optimisation and operational flexibility in the new era of intermittent generation and fast-changing user demand. Power grids were ...

In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

A control voltage is a voltage in the range of 0 - 10 volts (usually) which is used to control various modules in an analogue system. it may be alternating or direct current, though most often the ...

ACCORDING TO THE American Wind Energy Association, by the end of 2001, an additional 2000 MW of wind power will be added in the U.S. This new capacity includes four new wind farms of 200 MW or more ...

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Ameren Transmission Co. LLC has energized the first two of four innovative upgrades to ensure its grid remains stable during the utility’s transition to clean energy sources. Known as static ...

This isolated current regulator produces currents up to ±10 A, depending on load configuration, with current determined by the tap chosen and a 0- to 1-V control voltage V ISET. When measuring the ...

The distribution system, a key subset of the overall electric grid, provides power to residential, commercial and industrial customers. Voltage and reactive power management and control have been done ...
