Title: Modeling Converter Load Changes
Post by: sean0118 on May 30, 2014, 02:23:42 pm
Hi everyone,

I have a pretty basic question for you. At the moment I'm simulating an LLC resonant converter of my own design. It all seems to be working fairly well...  except changes in load.

I just want to see how it reacts if the load is changed form say 100% to 50%. However, at the moment I just switch one off and the other on. Which of course means the load changes instantaneously causing a large voltage spike.

What's a better way to model a load change? Some sort of transition period where it ramps down from 100% to 50%? How fast are load changes expected to happen in real life?   :scared: ;)
