Sometimes when a project is coming together, you need to cobble a tool together to get it completed. Whether it’s something very involved, like building a 3D printer to fabricate custom parts, or ...

We mentioned Pulse Width Modulation (PWM) when talking about [sprite_tm]’s marquee control. It’s a method of power control. While [sprite_tm] did it in software, [Afroman] sent along a very straight ...

Pulse-width modulation (PWM) generators are integrated in nearly every switching power device. This article shows two methods for implementing a stand-alone analog PWM waveform generator. These ...

Find a downloadable version of this story in pdf format at the end of the story. Boost power converters have been widely used for Power Factor Correction (PFC) in ac-dc conversions [1] and for power ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

The power stage of switching converters can be modeled essentially as a PWM-switch. A switch seems to be far from the kind of circuit element that can be linearized, but it can be. This Part 2 ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...
