I have followed the demo buck converter model for understanding thermal modelling. Now I have few questions:
1. I have extracted the Ri, Ci... parameters of foster circuit from datasheet for calculating Zth_Jc (junction to case thermal impedance). I want to verify these parameters by giving the power input to this foster circuit and observe the junction temperature. e.g at Ambient temp = 25 C, power dissipated is 92 W, R1 to R4 = 0.1746 0.6273 0.6306 0.0033, C1 to C4 = 0.0094 0.9217 1.1628 0.3433
How do I give an input of 92 W to this circuit? Is there a block of heat flow to physical signal converter available in plecs? How do I model this circuit?
