PWM (Pulse Width Modulation) or modulation with the width of an impulse, is a widespread term in the world of electrical engineering. It has a broad range of application, like in the field of telecommunications, audio equipment, servo motors, etc. Interesting for us enthusiasts is the application of PWM in voltage regulation. If you’ve followed our recent blog article on MOSFETs and VRMs, you know what we are talking about. Some of you probably already know the principle on which pulse width modulation (PWM) works, but nevertheless, we will explain how it actually controls the speed of a fan or a pump.
In short, PWM operates like a switch which constantly cycles on and off, thereby regulating the amount of power the fan or pump motor gains. The PWM system that is used for controlling fans and pumps works with the motor, either getting +12V (full power) or 0V (no power). To have a better understanding how this works, take a look at the chart bellow.
