Electrical Engineering Software

The PLECS® product family has been specifically developed to assist engineers with the design and implementation of complex power electronics systems. PLECS tools facilitate the selection of power-conversion topologies, allow for the sizing of components and thermal management systems, and expedite the conception and realization of sophisticated control algorithms.

PLECS Circuit Simulator

The PLECS Circuit Simulator makes it simple to model and simulate complex electrical systems along with their controls. Recognizing that power electronics systems have to be designed as a whole, Plexim has optimized PLECS to efficiently model and simulate complete systems, including non-linear elements and widely ranging time-constants. Supporting a top-down approach, PLECS tools can be used very early in the design process when detailed information about a new system is not yet available. As the design becomes more mature, the fidelity of the PLECS models can be enhanced by adding lower-level details to account for parasitic and non-linear effects.

With the intuitive, easy-to-use schematic editor, new models are set up quickly. Thanks to a proprietary handling of switching events, simulations of power electronic circuits are fast and robust. Whether one is simulating a simple power electronic converter or a complex electric drive, PLECS is a powerful tool that will quickly lead to accurate and meaningful results.

PLECS is available in two different editions. The user can choose between PLECS Blockset for MATLAB®/Simulink® and the independent PLECS Standalone solution.


The PLECS Coder generates ANSI-C source code from PLECS circuits by the simple push of a button. This allows you to simulate a system in PLECS first, then generate C code e.g. for real-time simulations or to execute on an embedded control platform. The code generation integrates seamlessly with Simulink Coder® (formerly Real-Time Workshop).
