eZdspLF2407 PWM problem

Submitted by Korhan44 on Wed, 08/03/2011 - 08:47

I want to generate a single PWM which duty cycle entered external at Vissim. When i use T1PWM, it give 2 kHz(constant) PWM and i cant change its frequency. I changed Time Rate Scaling and period but it wasnt effected. I couldnt use SV PWM, single PWM or dual PWM.. when i put it simulation screen and after run, this error was seen at screen (...can work only compiled mode). How can use Compiled MODE??

Thank you very much

You have two problems

  1. You must compile the diagram and download it. I suggest you watch the following on-line videos to understand how to do this:
    http://vissim.com/downloads/movies/vissim-ECD.html
    http://vissim.com/downloads/movies/vissim-ADC_usage_and_Digital_Scopes.html

  2. You need to scale the outputs of 3rd harmonic space vector wave form generator from +1..-1 to 0..1 as in the enclosed diagram.
