Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

The evacuation of bulk electrical power over long distances can be done mainly by high voltage alternating current (HVAC) ...

An SCR topology transmogrifies into BJT two-wire precision current source with a self-resetting fault-current limiter.

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...
