As we have a constant current source and a constant voltage source in PLECS, how to model a constant power source/sink? Does any block exist in PLECS which represents a constant power source/sink?

Hi bhaskar\_245,

Please have a look at the **DC Microgrid** demo model, which includes an implementation of a constant power load. This model is part of the TI Target Support Package and can be downloaded from our website.

You can access the zip file here:

Hope this helps!
