Even without the capacitor, the time constant and non-linear nature of the design idea’s (DI’s) PWM-driven circuit has limitations if used as a source of AC signals. Of course, the title of the DI ...

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 … ...

Through simple circuit modifications, designers can use peak current limiting to produce a constant current source.

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 ...

This design idea reprises another “ 1A, 20V, PWM controlled current source.” Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, ...

If you prefer, you can charge with a constant current source and get a nice linear charge. You can watch the voltage as the capacitor charges and when it reaches a certain point, you know a ...
