Improving convergence problems in the harmonic balance analysis


Convergence problems in harmonic balance analysis are a classic. I think every single human being involved in this stuff have struggled with them in many occasions. You will find plenty of technical papers talking about it. But most of them describe the issue in terms of the mathematical algorithm that is used to build the harmonic balance analysis in the CAD simulators. Not many of them help indeed to understand what can be done once the simulation has failed to converge.
Now, in a new entry in the section "Answering some Questions" it is available for downloading a brief studio regarding this problem, but focused in the case of QUCS Studio, using several examples of circuits and describing the problems that you will find when the convergence of the harmonic balance is an issue.

It is related to a question sent by email to the email address of this site.
