I determine losses of cores and windings with the thermal module. I would like to know how PSIM determines winding losses, as I get different results with my calculations.
I also noticed that winding losses increase by using larger conductors. However, this does not make sense since the resistivity (Ohm/m) decreases with size.
For example, if I use the example project Buck - inductor losses and change the wire size (e.g. from AWG18 to 17 or 10) and nothing else, I get higher winding losses.
I need the thermal module for a paper. It would be great if you could help me with some information.
