PLECS® is a circuit simulator that makes it simple to model and simulate complex electrical systems along with their controls. Supporting a top-down approach, it lets you start with ideal component models in order to focus on system behavior. Low-level device details can be added later to account for parasitic 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 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.
PLECS is now available in two different editions. Choose between the blockset for MATLAB®/Simulink® and the independent standalone solution:
Rather than relying on co-simulation, the Simulink engine itself solves the circuit equations alongside the control system. The PLECS Blockset offers full compatibility with simulation settings, supporting both variable and fixed time-step solvers.
PLECS Standalone (new)
Above you see a PLECS model of a 300 W switch mode power supply with power
factor correction. The simulation combines the electrical power ciruit, the
control with a standard IC and the thermal behavior of the semiconductors.
