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".
