Welcome to the PLECS Demo Model Library!

You can browse the model library on the left using the different model category types. Each model has documentation and is an actual circuit that is ready to use and that you can open and modify. In addition, you can filter the models by domain, including examples that contain detailed control schemes, thermal circuits, magnetic circuits, and mechanical systems.

The Controls model list contains circuits regulated in a closed-loop fashion using either analog or digital controls. These include various forms of current and voltage control for converters as well as scalar and vector control for variable frequency drive applications.

The Thermal model list includes circuits containing loss information for switches and the thermal structures they are connected to. Calculations for switching and conduction losses as well as waveforms for instantaneous and steady-state operating temperatures are shown.

The Magnetics model list includes circuits containing custom inductor or transformer designs based on magnetic components. This domain is intended for modeling complex magnetic geometric structures within a circuit with lumped elements using primitives such as windings, cores and air gaps. The available core models include saturation and hysteresis.

The Mechanical model list contains one-dimensional mechanical systems including highly non-linear effects such as backlash, hard stops and stick-slip friction. Combined with the electrical and control domains, the mechanical components facilitate the design of complete systems such as advanced servo drives and electric powertrains for vehicle applications.

The Tools model list contains examples showing some of the PLECS modeling tools, including steady-state and small-signal analyses for calculating open and closed-loop transfer functions. Also shown is the use of simulation scripts to control a simulation and perform parameter sweeps.
