I have a question about a tutorial video from PSIM: https://www.youtube.com/watch?v=iATO3mUKBPc
In this video, a MOSFET circuit is created using LTSpice .lib files from Cree. The parasitic drain and source inductance is indicated in the video with a parallel resistor. This resistance value and also the parasitic inductance can be taken from the .lib file. For the MOSFET used in the video the following is given in the .lib file: Ls = 9n, R_Ls = 10, Rg = 11.4, Lg = 15n, R_Lg = 10, Ld = 6n, R_Ld = 10.
My question is why this resistance value of 10 ohms corresponds to a parallel resistance of the inductance. I always thought that the parasitic inductance and the resistance are present due to the pins of the package (like TO-247). However, to my knowledge, such pins would present a series connection of parasitic inductance and parasitic resistance. Can someone please explain to me why a parallel connection is assumed?
Thank you in advance!
