What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

The aim of this tutorial is to introduce PWM functionalities. More specifically, we will experiment with creating and changing the duty cycle of a PWM signal. The example will be to change ...

PWM Output Another popular timer function is outputting PWM signals. Take a look at the sparkfun tutorial if you're not familiar with this topic. Put simply, PWM works by switching a signal on and off ...

How pulse-width modulation (PWM) works with switch-mode converters. How PWM can be used in different power-switching applications. Switch-mode converters employ a power semiconductor switch (usually a ...
