I remember there is a way to import the picture of “Transient Thermal Impedance vs. Pulse Width” (a plot where the Y-axis is C/W or K/W and the x-axis is Pulse Width (seconds). that is typically available on vendor’s datasheet for power devices, and make it to become the Thermal Chain (Cauer or Foster). But I don’t remember how to do it. Can someone help remind me the step by step instructions please?
Please see this video on the Thermal Import Wizard starting at T=6:25. The feature is described in the PLECS documentation as well.
