The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...

Current source inverters and converters represent a crucial class of power electronics devices that convert direct current from a constant current source into alternating currents with precise control ...

Recently, we’ve seen Design Ideas for programmable current sources with improved accuracy using the LM3x7 series of three-legged regulators. These designs also take advantage of those classic devices’ ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...

The general-purpose current source in Figure 1 is accurate within 1% and insensitive to temperature (less than 50 ppm/°C). It also has a high output resistance and a wide compliance range (4.3 to 34..

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...
