Is there a PWM block available in Simulink?

Hello.

I wonder if there is a PWM block avaible in Simulink?

It needs to be a 10-bit PWM.

I want to transform a signal between 0 and 1023 to 1 and 0.

The time period needs be avaible to change if needed so. For example 1 second or 1 milli second.

hi,

search for PWM in Simulink library, few are available in Simscape

You'll either need to buy the Simulink library or implement it yourself.

There are so many options for the generation of PWM in MATLAB. Some are listed as below: 1. You can use a function generator and specify your time period. 2. You can generate a PWM signal by comparing a modulating and carrier signals 3. You can write a simple .m file code for PWM and can send the coding to the simulink using PWM generator There are so many PWM generation options available in MATLAB/Simulink 2016 b like SVPWM generator, 2 level/3 level/multi level PWM generators

Hi. What is the name of the block on the function generator?

[ALBERT ALEXANDER STONIER]

it's a pulse generator..

We shipped a new PWM block in the Simulink library in R2020b. It is placed under Discontinuities library. Please check it out.

Also, we have introduced a new variable pulse generator block in R2020b as well.
