PLECS Blockset

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

If you are familiar with Simulink you will be able to use the PLECS schematic editor right away. A double-click on a PLECS block opens the editor window, and you can click and drag components and create connections with the same ease as in Simulink.

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.
