Plexim PLECS 5.0.6: Power Electronics Simulation Software

PLECS 5.0.6 is the latest stable release of Plexim’s high-speed simulation platform for power electronic systems, released July 13, 2026. It is available in two editions: PLECS Standalone (independent environment) and PLECS Blockset (integrated with MATLAB/Simulink).

Key Features

PLECS 5.0 Core Additions (Carried into 5.0.6)

The 5.0 series introduced major architectural improvements that continue to benefit users in this maintenance release:

  • PLECS Spice Add-on: Import SPICE netlists and connect them with other PLECS schematic components

  • Frequency Response Analysis: General-purpose small-signal analysis for time-domain simulations

  • FMI 2.0 & 3.0 Support: Import and export Model Exchange and Co-Simulation FMUs

  • Nanostep Functionality: New library blocks for on-board charger topologies including Bidirectional PSFB Converter and matrix converter frontends

  • Enhanced Solver Performance: Analytical Jacobian calculation by default for improved simulation of stiff systems

Version 5.0.6 Enhancements

  • Expanded component library with updated manufacturer models

  • Improved solver performance for complex systems

  • Enhanced support for the latest microcontroller families

  • Updated thermal loss models for modern semiconductor devices
