Gettings started with PLECS

PLECS is a software tool for system-level simualtions of electrical circuits developed by Plexim. It is not open-source, but it remains very accessible, which is a reason why we adopted it as one of the solutions to model our power converters. In this section we will explain to you how to get started with PLECS and run your first simulation.

Installing PLECS

To install PLECS, go to their website and download the standalone package. Choose your platform and follow the instructions.


There are three ways where you can use PLECS. Choose the one of your convenience.

PLECS provides a 90 days trial license for its products. Follow their dedicated page to get yours.

If you do not want to ask for a license, you can still use PLECS in its demo mode. You will still be able to run the simulations, but you will not be able to modify the model or save its data.

During the JCGE 2024 conference we will provide you with a special license that you can get with by clicking here.

This License will expire on June 23rd 2024.

Once PLECS is installed, you will see its library browser. You are now ready to start working with OwnModels.
