PLECS Standalone


PLECS® tools can be applied to many disciplines of power electronics engineering. Conceived with a top-down approach in mind, PLECS facilitates the modeling and simulation of complete systems, including power sources, power converters, and loads.

Included with PLECS is a comprehensive component library, which covers the electrical, as well as the magnetic, thermal, and mechanical aspects of power conversion systems and their controls.

Power electronics circuits are captured with a schematic editor in a way that is familiar and intuitive for electrical engineers. Typical power electronics components such as semiconductors, inductors and capacitors are placed on the circuit diagram and simply connected by drawing wires.

Powerful Functional Design Tools

In addition to the modeling interface and component library, PLECS provides several tools to aid in the design and analysis of power electronic systems.

  • During or after simulation, data is visualized in the PLECS Scope. Inspired by a real power electronics measurement and instrumentation system, the scope allows a user to extract the exact waveforms of interest as well as examine the data for post-processing and reporting.

  • The built-in Analysis Tools are easily set up to provide steady-state operating points or open-loop and closed-loop transfer functions. Additionally, state space matrices of a system can be extracted for advanced analyses.

  • Using Simulation Scripts the user can change parameters and invoke simulations or post-process output data and evaluate results.

  • The separately available PLECS Coder can generate real-time C code from a circuit or block diagram created with PLECS Blockset.

PLECS Standalone, The Independent Simulation Platform

PLECS Standalone is an autonomous software package for time-domain simulation of power electronic systems. If independence from other simulation platforms is important, PLECS Standalone provides the all-in-one solution for modeling complex electrical circuits and sophisticated controls in a single environment.

Due to its optimized engine, PLECS Standalone runs much faster than PLECS Blockset. With the comprehensive block library, PLECS Standalone offers a cost-effective yet powerful solution for dynamic system simulation in general.

Dedicated Solvers

PLECS Standalone comes with its own engine for solving circuit equations. The user can choose between variable-step and fixed-step solvers. Variable time-step solvers are generally preferred for accurate and efficient simulations, because they adopt the step size during the simulation depending on model dynamics. PLECS Standalone provides optimized implicit and explicit variable-step solvers for stiff and non-stiff systems.

Sampled Data Systems

The simulation engine allows the user to model sampled data systems, i.e. discrete systems that change only at distinct times. Users can model systems that are sampled periodically or at variable intervals, systems containing blocks with different sample rates, and systems that mix continuous and discrete blocks.


Simulation models can be exchanged with users of PLECS Blockset via import and export functions. All library components and modeling tools offered in PLECS Standalone are also available in PLECS Blockset. When importing a model created with the PLECS Blockset, the Simulink part is ignored.
