Hi,
When I am trying to import the thermal description file for MOSFET NTH4L014N120M3P which is in xml format it does not show in plecs even after importing the file in thermal description search path. How to resolve it or is there any way to use this file?
The onsemi models are not loaded by directly importing the *.xml files. Rather you need to load the onsemi device library, which contains the *.xml descriptions as well as a set of PLECS circuit components specific to onsemi devices. The *.xml files cannot be associated with generic MOSFET or Diode blocks from the PLECS library.
For instructions, refer to the Install.txt
file in the onsemi device library download, accessible through their Elite Power Simulator Tool (requires login). See the attached screenshot showing where to download the package from their website.
After installation, you can then add components from the “onsemi Block Library” section of your PLECS Library to your schematic, at which point you can assign the desired device specific thermal model.
