We have been big fans of Plexim’s PLECS simulation tool for power electronics for quite some time. We use it across most of our projects for component sizing, controls development and looking at system level behaviour. Our technical partner first came across it many years ago when it was still a free netlist-based basic tool provided by a university. Since then it has been fully commercialised and has come on in leaps and bounds. We have just added another seat of PLECS as we are so busy. This time we have decided to go for the standalone version which doesn’t require Matlab or Simulink. This version also has some additional features which we will no doubt find useful.
