The PLECS® Blockset is a unique tool for the fast simulation of power electronic circuits within the Simulink® environment. It allows combined simulations of electrical circuits modeled in PLECS with controls modeled in Simulink.

PLECS Circuit block

Each PLECS circuit is represented in a Simulink model as an individual block. You can feed signals into the block in order to control electrical sources or switch devices. Measurements taken in the circuit are accessible at the block outputs. You can display the measurements in a scope, post-process them in MATLAB®, or use them for controlling your system. Take advantage of the entire Simulink library and the vast choice of extensions to model special controls or other physical domains.

Intuitive schematic editor

To define the interface of a PLECS block you simply drag input and output blocks into the schematic. In fact, in many ways a PLECS block behaves just like a regular Simulink subsystem. Additionally you can use subcircuits (circuits within another circuit) to hide complexity or to create your own reusable components.

Use of Simulink solver

As you start a simulation the electric circuit is converted on the fly into a set of equivalent equations. Rather than relying on co-simulation, the Simulink engine itself solves the equations alongside the control system. The PLECS Blockset offers full compatibility with simulation settings, supporting both variable and fixed time-step solvers.

PLECS Viewer

The free PLECS Viewer enables licensed PLECS Blockset users to share their circuit models with users that do not have a license for PLECS. The PLECS Viewer allows you to simulate — but not modify — a circuit model, provided that it bears a special signature. This signature can be created by any licensed user with the full version of the PLECS Blockset.

Simulation of Electric Circuits at System Level

Whether you are simulating a simple power electronic converter or a complex electrical drive, PLECS is a powerful tool that will help you quickly obtain the results that you need. The simulation combines the electrical power ciruit, the control with a standard IC and the thermal behavior of the semiconductors. PLECS® is a circuit simulator that makes it simple to model and simulate complex electrical systems along with their controls.

Simulation of Electric Circuits at System Level - plecs standalone

If you want to be independent from other simulation platforms, PLECS Standalone gives you the all-in-one solution for modeling complex electrical circuits and sophisticated controls in a single environment. The simulation engine allows to model sampled data systems, i.e. discrete systems that change only at distinct times. PLECS Standalone provides optimized implicit and explicit variable-step solvers for stiff and non-stiff systems.
