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 ...

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 ...

Single-phase power factor correction (PFC) circuits--a kind of front-end AC/DC converters--are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

There are a handful of relatively dirt cheap synths out there like the KORG Monotron, but many of them use ribbon controllers that aren’t very precise. Ribbon controllers basically slide pots that you ...

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 ...

Here are some answers to frequently asked questions about motor control. Motors provide the driving power in almost every stage of the manufacturing and production process. With this much productive ...
