Hey guys,
do you have a simulation using Simulink or Pscad(?) of a PWM modulator using a NE555 timer?

 

Welcome and No. I do not.

 

Do you know any simulator that simulates this ne555? I have pscad and simulink and i didn't find yet this dispositive.

 

how about NI multisim

 

Do you know if it works using Win 7?

 

If I am not wrong. Many here in this forum use the free version of LTspice http://www.linear.com/designtools/software/ I do not use it my self. But take a look

 

Do you know if it works using Win 7?

LTSpice IV can simulate using the 555 and yes it does work on Win 7 and Win 7 x64bit.

 

LTSpice is a free download; google: "LTSpice download" and you will find it.

There is a model of the NE555 in the Misc directory; however it is an "idealized" 555 timer instead of a component model to make the simulation run faster. You can't buy a 555 timer that good.

I've posted LM555.zip, accessible from this post:
http://forum.allaboutcircuits.com/showpost.php?p=277737&postcount=6
with instructions on how to add the LM555 model to LTSpice.

 

LTSpice is a free download; google: "LTSpice download" and you will find it.

Note: will launch download of installer executable.
