Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...

A simple software method to increase the duty-cycle resolution in a digital pulse width modulation (DPWM)-controlled power ...

“Two halves make a whole” is a very old and often true maxim. For example, it’s almost always true when said about AC phase angle power control. You rarely want significant alternating half-cycle ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

Deciding between PWM and DC case fans can be confusing, but it’s important for the optimal performance of your computer. In general, PWM fans are quieter, more controllable, and more durable than DC ...
