If you hit the 15-node limit in the free PSCAD and cannot afford the $15,000+ license, do not panic. There are open-source and free alternatives that can handle power system transients surprisingly well.
Think of Scilab as the free version of MATLAB. Its graphical editor, Xcos, has a "Electrical" palette. While it is more suited for control systems than high-frequency transients, for educational power electronics (buck converters, inverters), it works perfectly and is 100% legal freeware. pscad free version download

PSCAD (Power Systems Computer Aided Design) is the industry-leading graphical user interface for the EMTDC (Electromagnetic Transients including DC) simulation engine. Developed by the Manitoba Hydro International (MHI) in collaboration with the University of Manitoba, PSCAD is the gold standard for analyzing transient behavior in power systems. Its graphical editor, Xcos, has a "Electrical" palette
Engineers use PSCAD to model everything from wind farms and HVDC transmission lines to protective relay coordination and fault analysis. It is a powerful, complex, and expensive piece of software—which is why the search term "PSCAD free version download" is so popular among students, researchers, and professionals looking to upskill.
However, the phrase "free version" comes with significant caveats. This article will clarify your legitimate options, warn you about common pitfalls, and guide you toward legal and safe alternatives.
