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 ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

This application note presents Z16FMC microcontroller used to control 3-phase brushless BLDC motors in a sinusoidal PWM modulation mode. It discusses the ways in which to implement sinusoidal PWM ...

The point of this guide is to show the latest and greatest in fan control technology on Intel Z270 motherboards and to help you understand what each brand has to offer in their high-end products. I ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude Pulse width modulation is a form of signal ...

Infineon claims to have come up with the industry’s first 16-phase digital PWM multiphase controller which enables currents up to 1000A and higher for next ...

Normal fan ports are only 1 amp, so I don't typically like running more than one fan per. That's only 5 watts, after all. Normal fan ports are 12V, not 5V. A lot of 12V fans won't even start at 5V, ...

Knowing what you know today about the enormous penetration of power supplies and their component parts at every level of electronic products and systems, would you believe that this huge industry rode ...

Interesting question. Before we could really answer it, we had to read up on pulse width modulation and why virtually all of the OEs now use PWM to control their fuel systems. To be clear, we will ...
