(Alternatively, you could add a SPICE Directive to your schematic, and paste the line in that SPICE Directive, and edit the name.) Edit the word "IPB036N12N3" to something new, such as "My_IRFB23N15D". txt file, and paste (Ctrl-V) the line of text into it. Close the file standard.mos without re-writing it. When you find it, copy (Ctrl-C) the entire line that includes that text. Open the file "standard.mos" in any text editing program. If using LTspice XVII, go to Documents\LTspiceXVII\lib\cmp\. Everything from ".model" to the end of the line is the SPICE model.Ī better way to get access to the model, is to do this: Go to your LTspice library area. Scroll to the right until you see ".model IPB036N12N3 VDMOS" followed by a lot of parameters. A list comes up, with the IPB036N12N3 highlighted. ![]() You can see its SPICE model by doing this: Right-click on the symbol, then click "Pick New MOSFET". You used the IPB036N12N3 transistor, which is built-in to LTspice. Let's start with your schematic, "SC_Converter_Switch_model.asc". (The trick is knowing what/how to modify.) ![]() If you have the model for a transistor that you want to change, it is easy to modify it. txt file and include it in the simulation, but I am still not sure if this works?" etc but I don't have access to those parameters, i.e I can't change them is spice. "I was thinking to change some parameters of the transistor, like Rdson, Is.
