PWM

Pulse width modulation

Description of the function used within the sequencer or implemented by

the pulseloop module

During Pulse Width Modulation, a duty cycle is modulated by a fixed
frequency square wave. This describes the ratio of ON to OFF as duty
factor or duty ratio.

Why PWM?

Many electrical components must be provided with a defined voltage.
Whether it’s because they do not work otherwise or because they have the
best performance at a certain voltage range (such as diodes or LEDs).

Diode characteristic

Since LEDs have a bounded workspace, the PWM ensures a variable
intensity of illumination at a constant voltage on the diodes.

In addition, the lifetime of a diode increases. The internal resistance is
ideal in this area. The diode gets time to cool down when operated with a
PWM in its workspace.

Implementation of PWM

Modulation frequency:

The basic frequency of the modulation is
defined by the cycle duration "T".
