Error in the thermal simulation model

Question

I am getting this error while using the thermal simulation model of my inverter circuit.

 

The device current (-1.13687e-13) is less than the lower limit specified in the thermal description (0).

You can turn this error into a warning on the Diagnostics page of the PLECS Simulation Parameters dialog.

 

 

I have reduced the input dc. Voltage to 1 volt. After that, I am also getting the same error.

 

 

This lower negative current should b rounded off to zero.

 

I am attaching here the.xml files of the switch and diode, which I have downloaded from the infneon website.

 

 

 

 

Please help me to resolve this issue.

Ajit, it looks like you reached out to support@plexim.com as well as posted on the forum.  I am going to copy the answer you received via support below so other users can benefit as well.  It also looks you didn't successfully attach your *.xml files as intended.

Answer 1

The XML files are missing a zero for conduction loss. Since PLECS has to extrapolate once no more information is available, the extrapolated device current for 0 V is less than 0 A, which is obviously not correct. With an additional point of 0 volts at 0 amps, this should no longer occur.
