Reliable simulation software is essential for designing modern power electronics. Plexim’s PLECS (Piecewise Linear Electrical Circuit Simulation) is a top tool for modeling complex electrical systems, thermal behaviors, and control loops.
| Feature | Trial License Limitation | |---------|--------------------------| | Simulation time | Max 20–30 seconds (typical) | | Component count | Restricted (e.g., ≤ 8–10 semiconductor switches) | | Thermal library | Partially disabled or limited nodes | | Export/Code gen | No C-code or HDL generation | | Save/load | Cannot save modified libraries | | Time limit | 30 days from first use |
Choose between Standalone or Blockset (depending on whether you have MATLAB/Simulink) and select your operating system (Windows, Linux, or macOS).
Navigate to the Plexim Trial Request page.
When requesting a trial license, you must select the PLECS edition that suits your workflow. The choice primarily depends on your existing software ecosystem and performance requirements. plecs trial license
This article provides a detailed overview of the PLECS trial, how to obtain it, its limitations, and how to maximize your evaluation period.
Start with a simple Buck converter to get accustomed to the environment, such as the open-loop and hysteresis controller models shown in.

The 15-state limit restricts model complexity. Examples of models:
She had solved it.
Note: Plexim often offers a free viewer version of PLECS that allows you to open and simulate pre-made models without a license, but the trial is required to create new circuits or modify existing ones.

For 72 seconds, the progress bar crawled. Then… convergence. The waveforms snapped into reality. The grid currents were clean. The junction temperature of the upper IGBT never exceeded 125°C. The efficiency was 98.2%.
PLECS includes an extensive library of pre-built application examples. Instead of building a complex system from scratch on day one, open a built-in demo model close to your application. This helps you quickly learn the software's UI, solver configuration, and scoping tools. 3. Test Thermal and Magnetic Modeling
PLECS is designed specifically for power electronics systems. Unlike general-purpose simulators that can become bogged down by the sharp switching transitions of power semiconductors, PLECS uses an efficient, piecewise linear approach. It allows users to model: Converters, inverters, and rectifiers.
Once Plexim approves your request, they will email you a license file (usually with a .lic extension). Save this file to your local drive.
